PUBLIC HEAAINGS: (Continued) John Bridges, Consultant with Cotton/Beland/Associates, Inc., and Rob Greene, Senior F Scientist, Woodward-Ctyde Consultants, explained the purpose of a Master EIR and con that a master EIR does not preclude the opportunity for public input. Council Member Nygaard stated she would like to have something written in the Plan stal Amendments would also be reviewed for compliance with the Vision Statement contained Plan. Mayor Lewis opened the duly noticed Public Hearing at 8:20 p.m., and issued the invita speak. Dolores Welty, 2076 Sheridan Road, Leucadia, representing Project Future, read a letter, i of which is on file in the City Clerk's Office, expressing concerns about the proposed upc Mark Chomyn, San Oiego Gas 8 Electric, 101 Ash Street, San Diego, expressed concer Policy Item C. 11, which suggested the elimination of 'powerline' easements from considc as meeting the 15 percent Growth Management open space performance standard. He felt C.ll should be re-written or dropped, so powerline easements could be considered to mc 15 percent Growth Management Plan. Mr. Chomyn also stated that SDG&E has had correspondence with the State Lands Comrr in which they say that the Agua Hedionda Lagoon is located under the Agua Hedionda Grant and is precluded from public holding by the State. Therefore, he requested that sta at the issue and make the appropriate modification to the EIR. In response, the CW Attorney stated that the City, in the EIR, is not adjudicating ownershig Lagoon and the issue is a private matter between SOGdE and the State, Pat Knox, 2002 Pintoresco Court, stated she had concerns about noise, traffic and air ( She stated that. she thougM the Growth Management Plan was supposed to precluc occurring of any 'hot spots' as mentioned in the General Plan, and wanted to know how cc those areas would be, including the intersections that will fail the Growth Manag requirements. Ms. Knox stated that the traffic circulation and noise issues need to be addi more fully. Bob Ladwig, Ladwig Design Group, Inc., 1947 Camino Vida Roble, Suite 108, read his letter August 9, 1994, a copy of which is on file in the City Clerk's office. He asked for langu be inserted allowing Melrose Avenue to be reclassified as a major arterial. I I I I I I I I I 1 I I 1 1 1 I I 7 August 9,1994 Page 5 PUBLIC HEARINGS: (Continued) Ofelia Escobedo, 161 1 James Drive, President, Barrio Carlsbad Association, stated they support the General Plan update, and requested staff to complete the Barrio Plan to be presented for final adoption and incorporation into the General Plan. Mike Howes, Hofman Planning Associates, 2386 Faraday, stated that it is difficutt to reduce the noise level to 60 CNEL in developments by prime arterials, freeways and the railroad. He requested that the staff be given the flexibility to allow developers to exceed the 60 CNEL, if a project cannot meet the standard without undue hardships. Leslie Sipple, 1:287 Vera CNZ, Oceanside, stated that she hoped staff would consider the people impacted by th43 changes in the General Plan. She stated that she is an Owner of 246 acres that is under the Mello-Roos, and there is no consideration given to property owners who might not be able to pay the taxes. Ms. Sipple asked for something to be done to give relief from the tremendous tax bill they owe. Smce no one else wished to speak on this matter, Mayor Lewis closed the Public Hearing at 8:47 p.m. Clarifications arid Responses to Questions Mike Holzmiller stated that powerline easements have never been counted toward the 15 percent open space requirement. The 15 percent open space is in addition to things already constrained, and this was addressed by the Open Space Citizens Committee. If all requirements have already been me?, and if this is an enhancement, such as a trail system or a buffer, then it can be counted. In repVy to query, Mr. Holzmiller stated that railroad rights-of-way are the same as future roadways--and not open space. Council Member Finnila stated if the Crty continues to grow, it will be necessary to look at a comprehensive noise ordinance where enforcement can be phased in gradually. With respect to the intersection ‘hot spots’, Mike Holzmiller stated that the EIR looks at a worst case srtuation. ‘The City’s ordinance says we can’t have a failure at an intersection, and that will still be the situation. Assistant Crty Engineer David Hauser, in response to query, stated that through the master planning process for Canillo Ranch, design standards for Melrose were reduced to those of a major arterial rather than a prime. However, it was still designated as a prime arterial and the width and improvements met the requirements of the prime designation. Mike Hokmiller stated that an annual report will be brought to the City Council which will provide an opportunity for the public to say what needs to be looked at with regard to the implementation of the General Plan. When land is changed to the Limited Control Zone, it is removed from the Mello-Roos and the tax burden stops at that time. Tem Woods, Planning Department, stated that the General Plan provides flexibility with regard to the 60 CNEL noise level, in that there are three findings required which would allow a project to exceed that level. I August 9,1994 Page 6 WBUC HEARINGS: (Continued) Mike Holuniller stated staff's concurrence with a suggestion in the letter from Project Future to include language that says *If a Regional HCP/NCCP is approved, the General Plan shall be amended to be consistsrf.

MINUTI PLANNING COMMISSION April 20, 1994 PAGE 2 Adrienne Landers, Senior Planner, reviewed the events of the General Plan public hearing from the two previous meetings, for the benefit of the Commissioners. She then explained the housekeeping changc contained in Errata #5. This errata includes changes requested by the Commission at the previous two meetings as well as an addendum that needs to be made to the EIR. The reason for the addendum is because the circulation study outlined 20 impacted intersections which could not be mitigated; however study failed to mention that some of those impacted intersections were not located within the City limits. Staff has corrected the number of impacted intersections from 20 to 12 full intersections and 2 partial intersections. Ms. Landers stated that the addendum also includes comments from the City of Encinitas which state th there may be additional impacted intersections south of La Costa Avenue and El Camino Real if project2 proposed within the City of Encinitas are constructed. These intersections would be impacted by region through traffic and are beyond Carlsbad's jurisdiction to control. However, the General Plan does conta statements which require the City to work with nearby cities in addressing land uses where there is potential incompatibility. Staff is doing as much as possible to address those issues but there still may t impacts which are beyond the City's jurisdiction. The inclusion of this comment from the City of Enciniti does not change either the impacts or the conclusions of the EIR. There are still significant but unmitigable impacts with regard to circulation. Commissioner Welshons referred to the map which shows the intersections of Melrose and Rancho San Fe and inquired if the projected intersections are based on developments which have been approved in other jurisdictions but not yet constructed. Ms. Landers replied that the information used by staff was based on the 1990 traffic model provided by SANDAG. That model was based on information provided SANDAG by adjacent cities. Ms. Landers stated that only one comment was received regarding the Housing Element. Margie Monro representing the League of Women Voters, requested that the technical information for the Housing Element be updated to include the census data from the 1990 census. Although this information may bf available on a local level, it cannot be used until SANDAG has compiled the data on a regional level, wh may take two more years. Commissioner Welshons inquired if the Housing Element could be invalidated if we don't use the same data throughout the document. Ms. Landers replied that the 1990 census data was used as a baseline fc noise and circulation, however it was not available when the Housing Element was prepared. Mr. Wayne added that the Housing Element is governed by an entirely different section of State law, whic specifies what data must be used. Carlsbad cannot replace the 1980 census data in the Housing Elemer with 1990 census data until SANDAG completes their regional needs study. Commissioner Welshons inquired when the SANDAG study will be available. Mr. Wayne replied that Carlsbad was due to update its Housing Element in 1996. However, due to budget constraints, that has been pushed back two years. He anticipates that it will probably be in 1998. Ms. Landers stated that the Housing Element was adopted and has already been certified by HCD. Commissioner Hall referred to page 60 of the Housing Element regarding CEQA Program 4.1 and asked staff to explain the housing impact fees. Mr. Wayne replied that this section means that when you provid for all levels of income within the City boundaries based upon jobs/housing, that the employees don't havc to travel as far to work in the City, and that contributes to an overall reduction of air pollutants. Commissioner Hall thought it had been decided to strike that. Ms. Landers replied that the Commission had discussed deleting it as a mitigation measure under air quality; however, there was no decision mad Staff had mentioned that the Commission may want to include a recommendation to the City Council to not approve that particular study when it is completed. MINUTES PLANNING COMMISSION April 20, 1994 PAGE 3 I 1 I I I I I I I I I I I Commissioner Hall stated that there is a lot of documentation in the General Plan which relates to that study. He does not like to vote on something if he hasn't seen the facts to substantiate it. Ms. Landers replied that the Comrnission would only be voting on having a study done; the City Council has alread approved the Housing Element and the need for a study to evaluate that particular fee. commissioner Hall referred to page 72 regarding job/housing impact fees and inquired if the study will call for some type of impact fees. Ms. Landers replied that the study would evaluate the possibility of dc that. Commissioner Erwin inquired if this section means that a nexus study is needed and that those corporations bringing in higher paying jobs would not be required to pay the fee. Mr. Wayne replied th would probably be done by categories, i.e. retail, research and development, manufacturing. Michael Holzmiller, Planning Director, added that the nexus study only shows that businesses located in the Ci have employees that need lower income housing. That nexus study will be used by the City Council tc decide whether or not the City wants to charge a fee. Commissioner Erwin inquired if this means that the impact of the particular company will dictate the amount that they will have to pay. Mr. Holzmiller replied yes. Commissioner Schlehuber commented that whenever you establish a nexus and fee situation, it has tc legally upheld. He is, sure that the City attorney will give it close scrutiny. Commissioner Hall rleferred to page 99, Objective 2.2, Development Standards, and requested staff to address modified codes and standards. Mr. Holzmiller replied that this is the ordinance which has air€ been adopted. It allows, by site development plan, consideration for modifying development standard5 The Planning Commission and the City Council have already used that ordinance on a couple of proje It allows the City the ability to modify development standards in order to get affordable housing in projc Commissioner Hall referred to page 109 and requested staff to explain the balance regarding housing impact fees. Mr. Hollzmiller replied that this is the study which has been done to determine if the City to charge nonresidential housing impact fees. Commissioner Erwiri referred to page 108, Objective 3.1 1, where it discusses reducing the size of hou by reducing costs arid increasing affordability. In the policy paragraph, where it discusses reducing tt size, he inquired if we will maintain our minimum setbacks, (20 ft. front, 5 ft. side, and 10 ft. back) or \ setbacks also be reduced. Mr. Holzmiller replied that there are no plans to reduce the setbacks. This program has already been implemented by the PUD ordinance which is currently in effect. When the Housing Element wits written, it included all of the things that were currently being done. Commissioner Erwin stated that he is also concerned about Objective 4.1. He states that this indicate will do a study and then take action. Mr. Holzmiller replied that the nexus study has already been pre by staff, although it hasn't gone to City Council yet. That nexus study fulfills all the programs and objectives in the Housing Element. Staff considers this study to be complete. The City Council may / decide to file the information. Commissioner Erwin inquired if it will be up to the City Council whether or not to charge a fee and wt be required to pay the fee. Mr. Holzmiller replied that this is correct. As far as staff is concerned, the have completed their task. Commissioner Hall doesn't read it that way. He believes that a lay person who reads this would assu Chairman Savary stated that the Commissioners should state their views and objections before the tentative vote. That will go into the record as a recommendation to the City Council. 1 I I I fee is required. I MINUTE I PLANNING COMMISSION April 20, 1994 PAGE 4 Commissioner Welshons inquired if the Commission is allowed to change a word from "will" do some to "may" do something. Mr. Holzmiller replied yes. Commissioner Welshons commented that Commissioner Erwin's point is that the sentence reads " ... tt measures will include but are not limited to the requirement for the developers to contribute and in-lie fee." She thinks Commissioner Hall is correct in assuming that a lay person picking this up would thir fee is required. Gary Wayne, Assistant Planning Director, replied that the structure of the paragraph is that staff will d study and where adverse impacts are identified, mitigation measures will be considered. The Council the right, ability, and purvue to say they don't want to do anything. The measures they will be conside include all of those things and they can say no to every one of them. Doing the study is all the City h ever committed to. It hasn't committed to adopting it, it hasn't committed to taking actions on initiatinc fee or requiring employer assistance to finance affordable housing, it hasn't committed to any of those things by the City Council approving this program 4.1. Commissioner Hall stated that this study has a tremendous impact on the future of Carlsbad. Not kno what the outcome of that is, and the way the sentence is worded, he has a lot of difficulty accepting it. thinks we have the cart before the horse. In his opinion, this should be added after the study, not now. sees no reason to do it now. Commissioner Schlehuber stated that the City can only amend the General Plan four times a year. Th a General Plan proposal. He is in favor of doing something tonight because we can't turn around and amend the General Plan the moment the City Council adopts it. Commissioner Schlehuber could acce the use of the word "may" as suggested by Commissioner Erwin. Mr. Holzmiller reptied that if the word a causing a problem, it can be changed. He reassured the Commission that the only intent is to bring 1 study forward to City Council. Commissioner Welshons stated that some of the Commissioners may have no qualms about a study bi they may have a problem with the whole idea of a fee. She thinks using the word "may" might diffuse t problem. Commissioner Schlehuber doesn't know how the Commission can vote on this when they have no information on the study. Until all the facts are on the table, it would be impossible to decide the feasibi of such a fee, and that in itself would require a full public hearing. Commissioner Erwin couldn't find any reference in the Housing Element to the use of minimum densitie Ms. Landers replied that this information is not in the Housing Element, but rather the Land Use Elemer It was also included in the EIR but has now been deleted. Commissioner Schlehuber stated that he could not accept any reference to minimum densities in the Housing Element and, if it is included, he would like it stricken. Ms. Landers requested a clarification of which "will" needs to be changed to "may." Commissioner Welshons stated: "Where adverse impacts are identified, mitigation measures will be considered to redl the impacts. These measures may include...". Commissioner Welshons called for an informal poll on all those in favor of changing "will" to "may" in Program 4.1. The sentence should read, "These measures may include...". The vote was 6-0 in favor. Commissioner Schlehuber called for an informal poll on all those in favor of accepting the Housing Element and all errata sheets, with the understanding that staff will correct anything in the Element that refers to a requirement for a minimum density. The vote was 5-1 with Cornmissioner Hall voting no. MINUTES PLANNING COMMISSION April 20, 1994 PAGE 5 I I I I I I I I I I I I I 1 I I I I I Commissioner Hall requested that the record show he voted no because of the wording in 4.0 and 4. Ms. Landers advis6d the Commission that when the General Plan goes forward to the City Council, i be in the form of a clean copy, including all of the changes made by the Commission. The agenda b include a discussion of the issues that are important to the Planning Commission. All comments anc opinions will be included. Terri Woods, Associate Planner, reviewed the comments made regarding the Open Space and Conservation Element. * Density Transfers. Ms. Besecker recommended density transfers in conjunction with providing op space. Staff believes it is premature to include this wording in the Open Space Element because just one of the methods under consideration at this time as part of City habitat management planr efforts. This topic is covered in the preliminary draft of the Habitat Management Plan and staff fec is the correct place for density transfers to be addressed. a Protection Measures. Dolores Welty, on behalf of Project Future, discussed a lack of specific pro1 measures for sensitive resources. She also expressed concern about the amount of time the City take in developing future programs for open space. Ms. Welty cited several policies which she be might take a long time to develop. One policy is to develop an inventory of habitat in the City. St already completed this program through the HMP efforts. The open space mapping has been cor through the Open Space & Conservation Resource Management Plan. Constrained lands have b mapped to a level of 400 scale, which is much more highly defined than that of most cities. Ms. V suggested that the City consider a much larger percentage of land to be set aside as open space claims that we only set aside 15%. In actuality, the City requires 15% of the developable land. FI all constrained lands must be set aside. Together, this far exceeds 15%. Staff is currently workir multi-species habitat plan which, if the HMP is ever approved, would result in far more open spa( the City. Staff does not recommend changing the 15% growth management requirement for ope at this time. e Financing. Ms. Welty made several comments regarding financing of open space. The Open SF Conservation Resource Management Plan does include several means to finance open space, in a possible general obligation bond and an assessment district to pay for maintenance and liabilit] trail system. Staff is also looking at numerous financing mechanisms for a habitat management including a mitigation fee and general obligation bond. e Sherman Property. Richard Chick commented about the constrained lands mapped on the She1 Property in Zone 25. A good portion of his property is heavily constrained. To alleviate his concl staff has no problem leaving the designation as hatched, with the understanding that a General I Amendment will be required at the time a specific plan comes forward. - Sunny Creek Property. Chase Coman commented about the heavy constraints on his mother's [ in Sunny Creek. Staff has written him a memo stating that we agree with a minor adjustment of open space boundary on his property. This change is reflected on the new draft Land Use Map. . Trails. Commissioner Hall commented that whenever trails are mentioned, they should be referr proposed trails. Staff has looked at the logistics of doing this but decided it would be cumbersoi add the word proposed throughout every document which discusses trails. Therefore, staff wou to include a citation in the minutes that the trails are proposed until a financing mechanism is in This would alleviate the need to process a General Plan Amendment once financing is confirme Commissioner Hall inquired if the Open Space Element or the Parks & Recreation Element should changed. Ms. Woods replied that staff would prefer to remove the reference to proposed trails in tl - MINU PLANNING COMMISSION April 20, 1994 PAGE 6 ti Recreation Element and then leave the Open Space Element alone. A citation would be added that tr are proposed until maintenance and liability can be financed. commissioner Hall stated that his only concern is next week or next month there may be a whole new SI of players. He wants the General Plan to mention that the trails are proposed rather than have to refer back to Minutes. After several suggestions were discussed, Commissioners and staff agreed that a sentence be added to C.l as follows: "Until such financing mechanism is in place, the trail system shall be considered proposed." Commissioner Welshons called for an informal poll on all those in favor of accepting the Open Space & Conservation Element, with the added sentence in C.l regarding the trail system as proposed, and a change to the Sherman property to the split general plan designation of TS/O/OS. The vote was 6-0 in favor. Adrienne Landers, Senior Planner, stated that there had been no public comments with regard to the Public Safety Element. Commissioner Welshons called for an informal poll on all those in favor of accepting the Public Safety Element and any errata corrections related to it. The vote was 6-0 in favor. Adrienne Landers, Senior Planner, stated that there had been no public comments with regard to the Ad Element. Commissioner Welshons called for an informal poll on all those in favor of accepting the Arts Element an any errata corrections related to it. The vote was 6-0 in favor. Adrienne Landers, Senior Planner, stated that the next item would be a final vote on the Master EIR and addendum. Commissioner Hall inquired if he needed to restate his objections for the record. Michael Holzmiller, Planning Director, replied that no errata sheets will be forwarded to the City Council. All changes will be made and a clean copy of the General Plan will be sent forward. As for the EIR, staff will place the addendum in the front of the EIR. The addendum to the EIR will contain all of the corrections which havc been made. The agenda bill which goes to the City Council will explain the process which was followed c the General Plan Update and it will include a detailed staff report of each informal poll which was taken and any comments or objections by Commissioners on specific items. A copy of the Minutes will also be included in the Council package. Commissioner Hall wants to make sure that the City Council members are made aware of why each Commissioner voted the way they did. Mr. Holzmiller replied that he could also cross reference the Minutes to each specific item. Commissioner Erwin commented that in the past, impacted intersections were identified as were proposec developments in surrounding communities which could have an effect on the City of Carlsbad. Mr. Holzmiller replied that the overall findings being made on the EIR do not override growth management.

Title 7 of the California Government Code states that prior to purchasing any land for public purposes, the City must bring the proposed acquisition forward tlo the Planning Commission to make sure it is consistent with the General Plan. /I course is allowed in any zone in the City with a Conditional Use Permit. Staff recommends approval. Commissioner Welshons noted that the Planned Industrial zone allows outdoor recreation uses on an interim basis. She inquired how staff can justify a golf course as an interim use. In her opinion, a goll course would seem to be more of a permanent use. Mr. Hunter replied that golf courses generally sta place until a better use comes along. Commissioner Hall inquired if the Commission is to assume that a golf course can be built at this loca Mr. Hunter stated no--only that it is consistent with the General Plan.

ZCA 92-4 - SECOND DWELLING UNITS ZONE CODE AMENDMENT - Request for approval o Negative Declaration and an amendment to various chapters and sections of the Carlsbad Munic Code (Title 21) to: (1) add a definition for Second Dwelling Unit, (2) allow the development of Second Dwelling Units through administrative permit in the R-A, R-E, R-if R-2, and R-3 zone and areas designated by a master plan for single-family detached dwellings in the P-C zones of City, and (3) amend the requirements for the creation of Second Dwelling Units in the R-A, R-E, R-1 , R-2, and R-3 zones and areas designated by a master plan for single-family detached dwellings in the P-C zones of the City. Chris DeCerbo, Senior Planner, reviewed the background of the request and stated that on March 2, 19 this Zone Code Amendment pertaining to second units was heard by the Planning Commission and the voted for a continuance to enable staff to research and respond to concerns regarding inclusionary housing requirements for second dwelling units, second dwelling units on smaller single-family residen lots of less than 7,500 sf., tandem parking for second dwelling units, and the impact of second dwelling units on the excess dwelling unit bank. In response to these concerns, staff is recommending the folloM ordinance revisions: . lnclusionary Housing Requirement - Staff recommends the deletion of the requirement for second dwelling unit owners to either pay the inclusionary housing in-lieu fee or deed restrict the second unii affordable to lower income households. Instead, staff recommends that the ordinance be amended tc stipulate that the maximum monthly rental rate for a second dwelling unit shall be affordable to lower income households. This provision would not be placed as a deed restriction on second units, nor wc it be monitored and enforced by the City, except on a complaint basis. It would, however, require tha the owner provide the City with prospective rental rate information for the second unit, upon applicatic for a building permit. The proposed rental rate would then be reported to the State Department of Housing & Community Development during our yearly report to the State. Provided that the rental rai is affordable, it would be counted towards satisfying the City‘s regional share housing needs. He note that staff has been advised by HCD that they will count second dwelling units in their calculation as 101 as the rental price meets the affordable criteria. - Second Dwelling Units on Smaller Single-Family Lots - Staff recommends the addition of new development standards to the planned development chapter of the municipal code which would reguli the placement of second units on single-family lots less than 7,500 s.f. as follows: (1) all second dwelling units shall be set back the same distance from the front and side property lines as the priman, unit on the lot; (2) the second dwelling unit shall be set back a minimum of 10 ft. from the rear properi line; (3) second dwelling units shall not be permitted to encroach into the recreation area of the primar residence and (4) for detached second dwelling units, the distance between the MINUTES PLANNING COMMISSION April 6, 1994 PAGE 3 1 I I I I I I I I 1 I i I I I 1 I I I Primary dwelling unit and the detached dwelling unit shall not be less than 10 feet. He showed ( on the overhead of where a second dwelling unit could be placed on various sized lots under 7,50 He also showed a photo of the only granny flat now existing in the City. Tandem Parking - Mr. DeCerbo stated that the present requirement for one additional parking sp( be located outside of the setback areas has prohibited the development of second dwelling units. recommends that the parking requirement be changed to allow tandem parking fo satisfy the park requirement. He showed several photos of tandem parking now existing throughout the City. Excess Unit Bank - There are currently 2,000 units in the City's Excess Unit Bank. These excess exist as a consequence of residential projects being approved at lower densities than permitted. E on this historical trend, staff believes that the units in the Bank are sufficient to meet our affordabl housing objectives without exceeding the dwelling unit limitations of the Growth Management Plai Commissioner Welshons inquired what kind of agreement the homeowner would have to sign sayinc the second dwelling unit is affordable. Mr. DeCerbo replied that no agreement would be signed. Th homeowner would only need to provide the City with the prospective rental rate upon application for building permit. Commissioner WeYshons inquired what would happen when a complaint is received. Mr. DeCerbo r that the City would then have the option of enforcing the rental rate. Commissioner Wellshons inquired if that means that today we won't enforce it but tomorrow we migt Gary Wayne, Assistant Planning Director, stated that the City couldn't selectively enforce the rental Zone code enforcement is on a complaint basis. Our ordinance stipulates that the rent for a second dwelling unit must be affordable. If the homeowner rents the unit for more than the affordable rate, would be considered a zone code violation, which is enforceable. However, enforcement is on a cor basis. Commissioner Schlehuber stated that he thinks this will be good because the units are small, and th affordable rental rate is relatively high. He doesn't think a homeowner would realistically be able to I higher rent than the affordable rate because of the size of the unit. For instance, the average rental a one bedroom apartment is $556 per mo. However, the affordable rental allowance for two person occupancy is $673 per mo. Commissioner Schlehuber feels the ordinance is well written and doesn there is anything to be lost. He thinks it is a win-win situation. Commissioner Hall commented that the average second dwelling unit will house a child, mother, or so, in all probability, there may be no rent paid at all. He also thinks it will be a win-win situation. Commissioner Welshons doesn't understand the requirement to rent to only low income. Mr. DeCei replied that this is necessary to ensure that second dwelling units qualify as affordable housing. Commissioner Welshons inquired if the reference to low income also includes very low income. Mr. DeCerbo replied that the mandate is only for 80% of the median income. Commissioner Betz stated that if a second unit is built on a new lot, she would rather see an extra p place provided for in the plans--perhaps a three car garage; she is not in favor of tandem parking I instance. Furthermore, she noted that second dwelling units can only be single story. She inquired the possibility of having a parking garage located under a living unit. Mr. DeCerbo replied that it is i to have a detached garage with a living unit above it. Commissioner Betz would like to see more flexibility if the lot is large enough. Gary Wayne, Assista Planning Director, replied that unique situations could be handled with a variance. - * MlNUT PLANNING COMMISSION April 6, 1994 PAGE 4 Commissioner Betz stated that variances are very exclusive and hard to get. If a lot is large enough, sh feels the ordinance should allow some flexibility. Commissioner Hall stated that the other complaint might be having a neighbor peer out a back window you while you are in your back yard around the pool. In order to protect the privacy of neighbors, he doesn't think added height should be allowed. Commissioner Schlehuber thinks that a second dwelling unit with two floors and parking below would lo like a Spite House. He is still convinced that tandem parking is a good idea. Commissioner Welshons inquired how services and facilities would be calculated and addressed for the second dwelling units which are created after the local facilities management plans (LFMPs) are in placc Mr. DeCerbo replied that the LFMPs are broken up into critical and non-critical facilities. For instance, sewer, water, and roads would be critical facilities associated with the preservation of health, safety, and welfare. Those have all been planned with excess capacity above the Proposition E caps. Second dwelling units would not exceed those caps. Commissioner Welshons inquired if fees are collected for second dwelling units. Mr. DeCerbo replied yt public facilities fees would have to be paid for each second unit when the permit is pulled. Those fees would go into the capital improvement project (CIP) budget for freeway interchanges, roads, libraries, Ci administration, parks, etc. Commissioner Schlehuber inquired if staff had any comments on the letters received from Fieldstone (dated April 6, 1994) and the Ladwig Design Group (dated March 31, 1994). Mr. DeCerbo replied that tt Ladwig letter requested second dwelling units in the R-P, R-T, R-W, and RD-M zones. Staff can supp that on lots which have single-family residences. As far as the request for gravel paving is concerned, staff explained to Mr. Ladwig that this requirement applies only to the rural estate zone with minimum on acre lots and 70 ft. front yard setbacks. Staff feels that concrete and asphalt paving are needed to preve erosion. Mr. Ladwig understands the reasoning and concurs with staff. Mr. DeCerbo stated that the Fieldstone letter requests that second dwelling units of less than 500 s.f. not counted as a unit under growth management. Staff does not have the authority to exclude these units from counting as dwelling units under growth management since they would be equipped with bath and kitchen f aci 1 it ies . Chairman Savary stated that the public hearing had been closed at the previous meeting but she reopenc it for new comments only. Sharon South, Director of Business Services for the Encinitas Union School District, 101 So. Rancho Santa Fe Road, Encinitas, addressed the Commission and stated that she is concerned about possible impacts to the district since the requirement for senior citizen occupancy was replaced with no age restriction. She feels that many of the units on larger lots could house parents with small children. Brooks Worthing, 1136 Larkspur Lane, Carlsbad, addressed the Commission and stated that he is a sma builder. He has had three requests over the years about the granny flat concept but the fees which were required stopped the projects cold. He likes the idea of this concept being loosened up because it is a good solution to the affordable housing shortage. He thinks it will be self-policing and that the units won' be rented anywhere near the maximum unless it is on a view site in La Costa. Robert Ladwig, 1947 Camino Vida Roble, Suite 108, Carlsbad, addressed the Commission and urged the Commission to support the revised ordinance. He thinks staff did an excellent job in researching what other cities have done regarding second dwelling units. He would be happy to answer questions, if any. MINUTES PLANNING COMMISSION April 6, 1994 PAGE 5 1 I I I f 1 I I I I 1 I I I 1 I I Doug Avis, Fieldstone-La Costa, 6670 El Camino Real, Carlsbad, addressed the Commission and s that he was a member of the affordable housing task force. Early on, he advocated the use of secor dwelling units to help fulfill the affordable housing quota. He likes the ordinance and thinks there ar places where this can be used. However, he would like to see a threshold below which the second d units would not count as dwelling units. Mr. Avis thinks there are many second dwelling units alreac there which need to be qualified so they can count towards affordable housing. He welcomed quest Commissioner Hall stated that there has been some discussion regarding an additional garage on n construction. Mr. Avis did not hear the earlier comments regarding the additional garage. However thinks the market would respond well to a second dwelling unit in the rear yard for some product tyy new project. Unfoirtunately, under the existing code, that unit in the rear yard would count as anothc unit. In his mind, lit should be counted towards the affordable housing quota. Commissioner Erwin inquired if a third garage could be dedicated to the second dwelling unit. Mr. 1 replied that he feels tandem parking, if any, should be allocated to the primary house. The third gar could be framed in and allocated to the granny flat. However, the reality of it is that people will still i the street, no matter what. People have a tendency to put their bicycles, barbecues, and storage in garage, and park the cars outside. Commissioner Welshons inquired if a tandem garage is one that houses two cars, side by side, with cars behind them. Mr. Avis replied that is correct. Many homes down by the lagoon have this arrangement because the lots are thinner and longer. Unfortunately, the market will not respond to tandem garages so they probably wouldn't get built. That is why you see three car garages in some developments. There being no other persons desiring to address the Commission on this topic, Chairman Savary c the public testimony closed and opened the item for discussion among the Commission members. Commissioner Erwin cannot accept tandem parking but he thinks second dwelling units will work 01 which are large enough. Commissioner Schlehuber stated that he likes the improvements to the ordinance which staff has presented tonight. The tandem parking doesn't bother him. He thinks it is a really good ordinance. Commissioner BeRz can support it as long as new construction does include a third garage designai particularly for the second dwelling unit. Mr. DeCerbo replied that this provision could be added for developments if the Commission desires. Commissioner Hall stated that he is neutral. He thinks the ordinance is necessary in order to proce Gary Wayne, Assistant Planning Director, requested a clarification regarding new construction. Commissioner Betz replied that she is talking about a new house being built from the ground up, wI be a single or a development. Commissioner Wels.hons requested staff to comment on Mr. Avis' comment regarding second dwell units being counted as separate units. Mr. DeCerbo replied that a second dwelling unit with kitcher facilities and a separate entrance would be counted as an individual unit under growth managemer has no authority to interpret otherwise. Commissioner Walshons inquired about Mr. Ladwig's request for gravel paving. Mr. DeCerbo replic this was only for very large lots with 70 ft. front yard setbacks. Staff cannot support that request. 1 I - MINU1 PLANNING COMMISSION April 6, 1994 PAGE 6 Commissioner Welshons inquired if dedicating a third garage specifically to the second dwelling unit wil diminish the tool to get these affordable units built. Mr. DeCerbo replied that it would be another hurdle and could possibly have that effect. Gary Wayne, Assistant Planning Director, stated that if a PUD came in for approval, the Planning Commission would have an opportunity to see it. But if someone came in with a standard R-1-7500 subdivision, all the Commission would see is lots. When they come in with the houses, they come for building permits and it doesn't come back to the Commission. He knows that it is a whole lot cheaper to build the second dwelling unit at the same time the primary unit is being built. If dedicating the third garage to the second unit is required, he is reasonably sure they will find a way to do it. Commissioner Schlehuber feels that putting a three car garage up front on a 7,500 s.f. lot, it will look like all garage and the house gets pushed aside. He thinks it will affect the design of the project and he is nc in favor of it but he will be neutral if that is what it will take to get it approved. Commissioner Welshons would like to know if this requirement will tie the hands of developers. Commissioner Noble supports the ordinance as it was presented. He feels that tandem parking works. t has seen it work in Terramar. The object of the ordinance is to get more affordable housing. He doesn't think it will have any impact on schools because schools will base their decisions on growth managemen He doesn't think very many of these units will be built and even if they are, he doesn't feel we will reach tl maximum growth established in the Growth Management Plan. Chairman Savary asked if staff wished to comment further. Gary Wayne, Assistant Planning Director, stated that the Deputy City Attorney has suggested that on page 5 of the ordinance, item (P), line 6, we should replace "the household" with "a low income household". He feels it would be more clear. ACTION: Motion was made by Commissioner Schlehuber, and duly seconded, to adopt Planninc Commission Resolution No. 3542 recommending approval of the Negative Declaration issued by the Planning Director, and adopt Planning Commission Resolution No. 3543 recommending approval of ZCA 92-04, based on the findings contained therein, including the change recommended by Robert Ladwig to also include zones R-P, R-1 R-W, and RD-M, as well as the wording change recommended by staff on page 5, item (P), line 6, and recommending that the City Council direct staff to subsequently open up the six week public review period to amend the City's six Local Coastal Progra segments accordingly.

EIR 93-01/GPA 94-01 - GENERAL PLAN UPDATE - A request for recommendation of certificatio of an Environmental Impact Report and recommendation of approval of a General Plan Amendmeni to comprehensively update the General Plan. Adrienne Landers, Senior Planner, reviewed the actions which had taken place at the last meeting and then reviewed each of the attachments which were included in the Commissioners' packets. She then MINUTES PLANNING COMMISSION April 6, 1994 PAGE 7 I I I I I I I I I I I I I I I I I I stated that after the public testimony, she or another member of the staff would present information on each Of the elements, discussion would take place, and an informal poll would then be taken. When al the elements have been considered, a final vote would be taken. Commissioner Hall inquired when the commercial aspect of property and the minimum dwelling units i zone would be discussed. Ms. Landers replied that they would both be discussed under Land Use. Chairman Savary stated that the public hearing had been closed at the previous meeting but she reopc it for new comments only. Mark Chomyn, representing San Diego Gas & Electric, 101 Ash Street, San Diego, addressed the Commission and stated that in the Land Use Element and the Parks & Recreation Element it discussa accessory uses in powerline easements and access to wetlands along the south shore of the Agua Hedionda Lagoon. SDG&E would appreciate the opportunity to review accessory uses and any matte1 public access becau!je of the topographical constraints along the south shore. Further, he stated that SDG&E is very open to expanding recreational facilities on the Agua Hedionda Lagoon but noted that lagoon was dredged and flushed as an adjunct to cooling waters for the power plant. Any consideratic uses in the lagoon must be considered along with the uninterrupted supply of cooling water to the po~ plant and SDG&E's continued ability to maintain dredging, etc. Mr. Chomyn also noted that in the Op Space & Conservation Element it identifies several portions of SDG&E's existing transmission easeme which might become components of the trail system. Where components of the trail system are implemented within the easements, SDG&E would appreciate the opportunity to consult with staff and private developers to ensure that access for maintenance is not compromised. He was happy to see E discussed and stated that SDG&E would be happy to provide information on this subject if there is intc Lastly, Mr. Chomyn's major concern is on page 18 of the Land Use Element where it discusses Precis Development Plans (PDPs). It is not clear if this refers to wastewater treatment facilities or if it also ap to electrical energy treatment of wastewater, maintenance and storage of operating facilities, and othc functions. He woulcl like a clarification since substations are currently serviced under a CUP. He thir the PDP process might be too involved for those types of uses. Commissioner Schlehuber advised Mr. Chomyn that the City cannot arbitrarily put a trail within an easement without talking to SDG&E. Mr. Chomyn stated that he was only reaffirming their concerns regarding implementation of some of the elements in the General Plan and they are willing to work WI staff to make them happen. However, there may be times when SDG&E may not be able to accompli 100% of the goals and objectives of the specific plan. He would like to know if the PDP is being appli all uses or just to uses defined as treatment of wastewater. Paul Yrisarri, 181 7 IHanscomb Drive, South Pasadena, addressed the Commission and stated that hc spoke at the last meeting but now wished to comment on the sunset provisions proposed for the commercial zones. He feels that the sunset provision will result in an undersupply of commercially z( land. If there is an iundersupply of commercial land, developers will go elsewhere and Carlsbad resid will be sending their sales tax dollars to other cities. He also commented on the open space maps an noted that they contain a legend that they are imprecise. He would like to see this comment carried Sharon South, Director of Business Services for the Encinitas Union School District, 101 So. Ranchc Santa Fe Road, Encinitas, addressed the Commission and reviewed the text of her letter dated April 1994. Essentially, the school district can accept the school mitigation as long as the growth manage plan continues in force. However, the school district is still concerned about the open space designa which they feel discounts the value of school sites. Mr. Holzmiller has advised them that existing ant future school sites would be noted on the maps and would bear the same designation as surroundin! properties. With this change, the school district could support adoption of the Plan. Ms. South subn copy of her letter to each Commissioner and a copy of the letter is also on file in the Planning Depart I text as well. MINUTE PLANNING COMMISSION April 6, 1994 PAGE a Elsa Benguiat, 2947 Lexington Circle, Carlsbad, addressed the Commission and stated that her comr were in regard to the Noise Element. She and her husband had written a letter to the Planning Commission suggesting an alternative process for handling barking dogs. They received a reply stat1 that staff would look into the possibility of changing the City's enforcement method for barking dogs. Stated that it took them over two years to take care of one dog using the present system. Even after 5 to court twice, there are still other barking dogs in her area which need to be controlled. She has a lei from the Office of Noise Control explaining a very simplified system which is used in San Diego Couni and the North County cities of Del Mar, Solana Beach, Encinitas, Oceanside, and Escondido. She wc be interested in what type of effective system the City might be considering. Commissioner Erwin inquired if they had to file a criminal complaint in order to take care of their probi Ms. Benguiat replied that they had used two systems and a citation was finally issued, but it did requirl them filing a criminal complaint. It was a very frustrating ordeal. Commissioner Erwin asked to see the letter from the Office of Noise Control. Ms. Benguiat replied tha only had one copy. She let Commissioner Erwin read it and stated she would send staff a copy of it a1 this meeting. Mark Chomyn, SDG&E, returned to the podium and stated that he had neglected to mention a possiblc error on page 23 of the Parks & Recreation Element, Table 5, where it states that Agua Hedionda Lagc is owned by the State. He thinks that should be changed to SDG&E. Commissioner Noble advised Mr. Chomyn that this had come up once before when he served on the Beach Erosion Committee. He stated that the Parks & Recreation staff has determined that the lagoon owned by the State because it is considered to be navigable waters. Mr. Chomyn stated that he will als look into it further. John Freidlander, 2245 Nob Hill Drive, Carlsbad, addressed the Commission and stated that he is concerned about the landing pattern for aircraft at Palomar Airport. He spoke at the March 16, 1994 meeting but wanted to mention tonight that, since the last meeting, another airline is currently in the process of being approved for landing. This will essentially double the number of commercial flights pel day into Palomar Airport. In effect, this doubles the impacts to all residential property within the flight pattern. Commissioner Hall inquired if this is commercial flights or total flights. Mr. Freidlander replied that he is speaking of commercial flights. There being no other persons desiring to address the Commission on this topic, Chairman Savary declal the public testimony closed and opened the item for discussion among the Commission members. Before going into the individual elements, Ms. Landers stated that the consultant, John Bridges, would lil to address some of the EIR comments made at the last meeting by Dolores Welty. John Bridges, Cotton Beland & Assoc., stated that the letter from Project Future, presented by Dolores Welty at the last meeting, mentioned that the EIR document and the mitigation were both very broad in scope and relied on City programs which may or may not take place. Mr. Bridges stated that a General Plan is supposed to be broad in scope because it is a set of actions (rather than a single action) which wil take place over the next 10 to 20 years. As a result, the environmental analysis which is conducted is als of a broad nature because it, too, covers a 10 to 20 year span. As each project comes forward, there will be a specific assessment made regarding environmental impacts and mitigation. The Project Future lette also stated that the draft EIR needed to be recirculated because new information has become available which was not included in the document. He noted that their were only 10 or 11 comments received on tt EIR when it went out for public review. In accordance with CEQA, Section 9 of the EIR includes all of the MINUTES 30RRECTED PLANNING COMMISSION April 6, 1994 PAGE 9 written comments which were received, as well as the responses. Several changes were made as a of those comments. There is a letter from Project Future in Section 9, and the response is there as That letter was almost identical to the Project Future letter presented by Dolores Welty at the March 1994 meeting. Mr. Bridges sees no reason for the document to be recirculated since there have bec substantial changes. Ms. Landers stated that Housing Program 4.1 which was discussed at the last meeting has now bee completed and is in the City Manager's office for review. It contains information on a non-residenti, impact fee for commercial development. It is mentioned as a mitigation measure for air quality and Commission woulld like it deleted, it could be included in the Minutes of this meeting as a citation ac the City Council of the Commission's desires. Commissioner Welshons asked where this information is located in the document. Ms. Landers reF that it is contained in the Mitigation Monitoring Checklist on page 13 under Air Quality, item 16. Commissioner Erwin referred to the Project Future letter and stated that they see it as deficient bec the defects they listed. Karen Hirata, Deputy City Attorney, replied that Mr. Bridges addressed theii concerns appropriately because a General Plan is intended to be broad in scope and more details a provided when specific projects come forth. In the Laurel Heights case, there was an allegation tha information came up after the draft EIR was prepared. When the final EIR document came forward Board of Regents, it was substantially different than the document which the public had received, si had not been given an opportunity to comment. Mr. Bridges responded adequately to Project Futui concern by stating that this draft El R , ~~~fBm~/IWI6fIln~~~bT~I~~~~/~/~~~/~~~/~~~~ the exception of a few minor changes, is the same one which was presented to the public, sc same as the Laurel Heights situation. Adrienne Landers, Senior Planner, inquired if there were any questions regarding the Vision Staten the General Plan. Commissioner Hall requested she explain how the goals, policies, and objectives work and how the carried on through each of the elements. Ms. Landers replied that the goal is a very broad concept in mind as you go through the element. The objective breaks down that goal into various compone discusses how it will be achieved. In effect, the objective is an intermediate step towards attaining i The program and policy breaks the goal down even further. The Vision Statement incorporates the goal of each element and then as you go through each element that goal is reinforced. Adrienne Landers;, Senior Planner, reviewed the comments made regarding the Land Use Element - Carlsbad Research Center. Mr. Eyreni objected to the change of land use designations from PI/RS/CTTS to PI (Planned Industrial). After reviewing this request, staff still recommends the PI designation change. This change is consistent with what has been done for other industrial spec plans and eliminates a long series of designations on the Land Use Map. e Minimum Density. Ms. Besecker commented that it would be difficult to achieve the minimum dc some residential projects due to environmental constraints or neighborhood compatibility. This ( in Arroyo La Costa. Exhibit "A" prepared by staff, includes revisions which allow more flexibility e So. Coast Commuter Corridor. Ms. Besecker recommended that this corridor be deleted from th section. Since Specific Plans will be required for the large vacant parcels along this corridor, st2 accept this recommendation if the Commission concurs. I Feasibility Study on Commercial Sites. Ms. Besecker questioned this policy because she felt it p fundamental decisions about a project into the hands of a third party. This is a program that ha MINU I I I I I I I I I I I I I I I I I I I regarding density. PLANNING COMMISSION April 6, 1994 PAGE 10 the General Plan for many years with regard to Neighborhood Commercial development and staff is simply broadening the policy to include community and regional commercial development. It is appropriate to require feasibility studies for larger sites as well to determine if they are appropriate for commercial development. * Periodic Reviews of Commercial Sites. Comments were made by Ms. Besecker and Messrs. Yrisarri i Ladwig regarding the two year periodic reviews. Exhibit "B prepared by staff, modifies this section wi regard to larger commercial properties. * Schools. Marshall Krupp expressed concern with regard to the deletion of the performance standards from the Land Use Element and how this affects school mitigation. These standards have been put ba into the Land Use Element. He also had a problem with the zoning of school sites as open space. Sta felt that zoning of school sites would be more appropriately discussed at the time a school conditional use permit is reviewed. Zoning is not really an appropriate discussion in the General Plan and therefo all references to zoning of school sites have been removed in Errata #3. Mr. Krupp has reviewed both changes and has found them to be acceptable. The Commission has received a copy of the revised language which includes a minor modification as follows: "...with the previous General Plan land use designation or a land use designation compatible with adjacent uses...". Mr. Krupp was also concerne that the generation rates for schools were not included in the text. The generation rates referenced in the EIR were received from the school district. If these are out-of-date or inaccurate, staff requests th the school district note this in the record. Arto Nuutinen requested a condition be included in the General Plan which was used in the Zone 20 Specific Plan to fund new school facilities using Mello Roos. Staff indicated that this is a project mitigation measure which should not be included in a broad policy document like the General Plan. Staff would prefer to do that on a project level basis. Mr. Nuutinen also stated that the school mitigatio measures in the EIR and Growth Management Plan are inadequate. The City disagrees because the current process through the Growth Management Plan allows the school district to vary mitigation as student generation rates vary. The City believes funding sources are the district's issue and that this is matter which the school district needs to pursue with the State. * Precise Development Plans. SDG&E inquired about the use of PDPs for all types of utility uses, including substations. Mr. Wayne stated that PDPs will be used for all utility uses with a "U" designatio Substations would still come under the CUP process. Commissioner Welshons inquired if the Olivenhain Elementary school site on El Camino Real had been corrected. It should be located on Rancho Santa Fe Road. Ms. Landers stated that this was overlooked and would be corrected. Commissioner Erwin referred to Exhibit "A" and stated that he has a problem encouraging developers to increase densities. He does not feel that the citizens of Carlsbad want densities increased. Commissioner Schlehuber agrees with Commissioner Erwin. He would like the entire last paragraph of page 16 deleted. Michael Holzmiller, Planning Director, feels that something needs to be included which states that if anyone goes below the density range it is still consistent with the General Plan. Staff has had some problems with this in the past and they are trying to eliminate them now. Commissioner Hall agrees with Commissioners Schlehuber and Erwin, although he could accept something if it was very simple. Mr. Holzmiller stated that they could eliminate the whole thing and includc a sentence to the effect that if the City approves a project below the minimum General Plan density range, it would still be consistent with the General Plan. MINUTES PLANNING COMhAlSSlON April 6, 1994 PAGE 11 I 1 I Commissioner Erwin referred to Mr. Nuutinen's letter of March 16, 1994, and asked if staffs recommendation is to not include in the General Plan the agreement between the City Council and MS. Landers replied that staff does not feel this statement should be included in the General Plan be it is something which should be done at the project level review. Mr. Wayne stated that once it is co in the General Plan, it would require a General Plan Amendment to make even a minor modificatior Karen Hirata, Deputy City Attorney, advised the Commission that this language was approved by th Council but only for certain zones. The Council did not adopt a general policy. Commissioner Sctilehuber referred to Exhibit "B" and stated that he likes the five year review for commercial sites because it allows for changes if they are needed. He thinks this is quite fair. Commissioner Betz disagrees. She would like to see that part stricken. commissioner Hall inquired if this has been done in the past. Ms. Landers replied that it is somethii and has not been done before. Commissioner Hall would like to see it stricken also. He feels that a owner of commercial land should be able to develop his property whenever he sees fit. He thinks th is a property right which should not be taken away by a City or governmental agency. If a property has been paying tiaxes on commercial land, he should not have to come to the City every two years order to keep his commercial zoning active. This sends a very clear message that we do not want I to invest in our community. Michael Holzmiller , Planning Director, stated that the proposed program came about as a result of t economic development policy which was adopted about six months ago. Sometimes when a comm venture wants to locate in the city, it may be on land which is not zoned commercial. He used as ai example the Price Club. Staff had tried to encourage them to locate at El Camino Real and Collegr one of the reasons they did not locate there was because of the commercial designation right acros! street which had been zoned commercial for eight years. Commissioner Hall replied that the property owner who has been paying taxes on commercially zor property for eight %years should have more rights than someone new coming into town. He thinks it the wrong message to people who have invested in this community over the past eight years. It sa) you don't do something with your property soon, those outsiders who wish to come to the communi have priority. Commissioner Erwin says he can support the review because it makes it consistent with the way WE master plans. Ms. Landers replied that it is similar after the first two years. Then they would be sut a five year review just like a master plan. Commissioner Hall stated that he may not want to do something in two years. As a property owner should have that right. He should not be demanded to do something with his property. Commissioner Welshons asked the attorney if this would be an impingement on a property right. h, Hirata replied that in a general sense it is a property right. However, zoning can be changed by the and there is no legal impediment to going in and changing zoning. There are laws against spot ZOI because, in the past, there have been some dishonest dealings which have taken place. She feels ' Commissioner Hall's argument is more of a moral issue than a property right where the City could ( Gary Wayne, Assistant Planning Director, stated that many cities that create general plans will desi up front, certain areas as potential commercial. Carlsbad has traditionally been very different. Whc project comes into this City, commercial zoning is often created for that project. He thinks that is w original General Plan carried this review clause. If the project did not get completed for one reason I I I I I I I I I I I sued. I I I I I MlNUl PLANNING COMMISSION April 6, 1994 PAGE 12 another, the zoning was not deemed to be a God-given right and it could be changed. If we are going change our philosophy now, we would also need to change our zoning ordinance. Commissioner Betz stated that there are so many things which go into developing commercial property that five years may not be enough time. She would like to see this stricken. Commissioner Hall stated that if people in Carlsbad who own commercial property realized what was or the table tonight, he would venture to say this room would be packed and out the door. He thinks this is the wrong message to send. Furthermore, he feels that five years is too short a time and this is a major issue. He believes this topic should have its own hearing. Ms. Landers replied that all of the vacant commercial property owners were notified of this hearing. She did not hear from anybody, although she notices that Mr. Morey is here tonight. Mr. Holzmiller commented that when staff originally started working on this, consideration was given to only applying it to the future and grandfathering the existing zoning. Staff is currently dealing with somc commercial proposals where the applicant has said they can't get someone interested in a particular site unless it has a commercial designation. They have had requests for conditional two year zoning so the property can be marketed. If, after two years, nobody is interested in the property, they are willing to rei back to the existing zoning. Commissioner Hall could buy off on the future but he is concerned about those property owners who ha1 owned commercial lots for many years. These properties don't change hands that often. Ms. Landers stated that if the Commission would like to make that change, it could be easily accommodated. Commissioner Hall would like to hear from Mr. Morey, who is in the audience. Fred Morey, representing La Costa Towne Centre, addressed the Commission and stated that this prope has been on the General Plan Land Use Map since 1972. The development of Phis property depends on development north and south of it, which could take another ten years. In their most optimistic viewpoin they hope to have occupancy on some part of it within 5-6 years but they can't do any planning if they have to deal with these reviews every few years. It is of great concern to him. Commissioner Erwin noted that staff seemed to need this review in order to take care of some problems. He would like to know if this tool is needed in order to review existing commercial property to make some decisions or if it is only needed as a future tool. Ms. Landers replied that it would be a valuable tool to us to evaluate existing commercial sites because some sites impact other sites. However, staff would be opc to some modifications to Exhibit "B if necessary. Commissioner Schlehuber called for a straw vote on all those in favor of accepting Exhibit "B." The vote was 5-2 with Commissioners Haft and Betz opposed. Commissioner Welshons inquired about the option to delete the study for the commuter corridor (red-lin version, page 35). Ms. Landers replied that this section could be deleted if it is felt that the comprehensic plan is not needed. Mr. Wayne feels that item #C could be deleted since there is already a requirement fl a Specific Plan along this corridor. Commissioner Schlehuber called for a straw vote on all those in favor of accepting the Land Use Elemenl as presen!ed and amended, namely the language in Exhibit "A deleted and replaced by one sentence as read into the record by Michael Holzmiller, Exhibit "B" retained as is, item #C regarding the South Coast Corridor study deleted, Attachment #6, and all changes pertinent to Land Use on Errata Nos. 1,2 and 3. The vote was 5-2 with Commissioners Hall and Betz opposed. MINUTES PLANNING COMMISSION April 6, 1994 PAGE 13 I I I I 1 I 1 1 I I I I I I I I I Terri Woods, Associate Planner, reviewed the comments made regarding the Noise Element. - 60 CNEL. Comments were made by Ms. Besecker and Mike Howes that they are opposed to the 61 CNEL and the statement that noise walls are discouraged. Staff believes 60 CNEL is a reasonable standard. The City has been implementing the 60 CNEL standard since Policy #17 was adopted ir 1990. There has been only one project since Policy #17 was adopted where 60 CNEL was not ach and, in that case, findings were made to exceed the standard. - Noise Walls. Staf is recommending various types of noise walls. Ms. Besecker requested informa on how the noise walls would be implemented. Staff has proposed a draft Noise Guidelines Manu which would contain that information. The manual is available in draft form and is anticipated to bc brought forward for review and approval by the Planning Commission following adoption of the Gel I Plan. e College Avenue. Several comments were received about noise along College Avenue in the northe portion of the City. It is the City's policy that we won't go back and retrofit areas, In this case, hor cost estimates anld mitigation measures will be provided to the homeowner associations and they w have to decide how they want to proceed. * Aircraft Noise. The County is preparing a master plan for the airport and is in the process of install noise monitoring equipment in the City which will be able to detect which aircraft is violating airporl take-off and landing procedures. This will enable the County to go directly to the offender and ad\ them of the violation. * Barking Dogs. The issue has been looked at extensively by City staff. The City has adopted the County's Animal Control Ordinance by reference. The City contracts with the County to implement procedures. The City Council has determined that these methods are adequate. Commissioner Welshons called for a straw vote on all those in favor of accepting the Noise Element fi all references to CNEL being changed to 60 CNEL, and all changes pertinent to Noise on Errata Nos. and 3. The vote was 7-0 in favor. David Hauser, Assistant City Engineer, reviewed the comments made regarding the Circulation Elemc - Melrose Drive. Ruth Besecker, on behalf of the Fieldstone Company, requested that Melrose Drive of Rancho Santa Fe Road be fully downgraded from prime arterial to secondary arterial status. Thc Circulation Element presently calls for this to go from prime arterial to major arterial, with the poten secondary arterial. Staff would like to keep this flexibility in case plans change and in order to pres( adequate right of way. He stated that the map is in error and should correctly read major arterial. The Friends of Carrillo Ranch have requested that Melrose Drive between Palomar Airport Road ar Alga Road be deleted or greatly downgraded since Highway 680 was cancelled. Staff would like to retain the existing classification of prime arterial since SANDAG predicts that, even without the soul connection, Melrose Drive will have traffic volumes ranging from 34,000 to 54,000 ADT on this segn In addition, the recently approved Carrillo Ranch Master Plan provided a standards reduction on thr horizontal and vertical design criteria from prime arterial to major arterial. This reduction reduced t Melrose fill height from 80 ft. to 50 ft. * Future Transportation Needs. Dan Downing has requested more consideration be given to future n of transportation, Le. public transportation. Staff does not recommend changes or taking additional dedications at thb time since transportation needs are served by North County Transit District and 1 have no plans in place to move beyond established roadways and the rail corridor. I MINUTE: PLANNING COMMISSION April 6, 1994 PAGE 14 . Palomar Airport Road Access. Paul Yrisarri, who represents property owners along Palomar Airpor Road, has requested that the City provide some policy to protect historical access to those propertie the Laurel Tree intersection. Staff believes existing policy is adequate regarding limiting access to F arterials and does not recommend any changes at this time. Mr. Yrisarri's request can be accommodated through the standards variance process and is best considered at the time a development application is submitted. . Commissioner Betz stated that C-1, Alternative Modes of Transportation, states that the Plan encoura construction of sidewalks in high pedestrian areas such as schools and commercial centers. She note that there are no sidewalks at Magnolia Elementary School nor Valley Junior High School. She would to know where on the prioritization list for sidewalks that these schools fall. Mr. Hauser replied that thc are many variables to establish the priority for sidewalks. Schools are very high priority and he knows plans are currently in process to construct sidewalks on Valley, between Chestnut and Magnolia and al along Monroe Street at its intersection with Magnolia Street. Commissioner Welshons called for a straw vote on all those in favor of accepting the Circulation Eleme including any changes pertinent to Circulation on Errata Nos. 1,2 and 3. The vote was 7-0 in favor. Terri Woods, Associate Planner, reviewed comments made regarding the Parks and Recreation Elems . Trails. Commissioner Hall commented that he would like all references to the Citywide trail system noted as the "proposed" trail system. Staff has noted that request, is in agreement, and will make th appropriate changes. Keith Beverly, Senior Management Analyst, Parks and Recreation, discussed the comments made by SDG&E. * SDG&E. Mr. Beverly stated that SDG&E has requested that the City enter into agreements to establi and maintain access along the south shore of Agua Hedionda Lagoon. The City currently has in piac long term lease agreement for a 92 acre Hub Park area on the south shore of the Lagoon with provis for significant extensions of time. There is also an agreement in place for Macario Canyon which includes the hub area. There are also conceptual plans for a beach area boat dock facility on the sot shore of the Lagoon. In addition, there are conceptual plans to establish connecting access between Veteran's Memorial Park and Hub Park. SDG&E has also requested limited public access to the Agc Hedionda Lagoon wetlands. This issue will be regulated by the environmental agencies and is identi on the conceptual pian of Macario Canyon. SDG&E is concerned about safe recreational use at the Lagoon on a self-sustaining basis. The City currently provides a Lagoon patrol to ensure safety of boaters and passive use of the Lagoon. Commissioner Welshons inquired as to who owns the Lagoon, the State or SDG&E. Mr. Beverly stated that in the ownership matrix the owner is identified as the State. There is a question regarding the stati of the lagoon as an open navigable waterway. There was a question about the City's ability to require insurance and the State Lands Commission has advised that it is an open navigable waterway. The Cil has since dropped its requirement for insurance because the owners and operators of Snug Harbor reqi insurance. Commissioner Erwin inquired about the issue of pocket parks in master planned communities and inqui if we were changing our philosophy. Mr. Beverly replied that the City supports pocket parks to the exter that those parks are owned and maintained by homeowner groups and not the City. Commissioner Erwin called for a straw vote on all those in favor of accepting the Parks and Recreation Element with any changes pertinent to Parks and Recreation on Errata Nos. 1 through 3. The vote was 7-0 in favor.

APPROVAL OF MINUTES: Approval of the Minutes for March 2, 1994 was continued to the April 6, 1994 meeting. PUBLIC HEARING: 1. EIR 93-01GPA 94-01 - GENERAL PLAN UPDATE - A request for recommendation of cert of an Environmental Impact Report and recommendation of approval of a General Plan Amer to comprehensively update the General Plan. Adrienne Landers, Senior Planner, explained that since the General Plan is a very lengthy docume Environmental Impact Report will be reviewed first and then each section of the General Plan will b reviewed and discussed. She will make her presentation first, Planning Commissioners will ask qu and then public testimony will be taken. After public testimony is closed, Planning Commissioners have their discussion followed by a straw vote. At the completion of all discussion, a final vote will taken. Commissioner Hall commented that he wants to make sure that everyone in the audience has an opportunity to cornment on the various elements. MlNUl March 16, 1994 PAGE 2 PLANNING COMMISSION Commissioner Erwin stated that he agrees with Commissioner Hall. Also, he would like the purpose of i straw vote to be whether or not to move forward to the next element. He wants the approval vote taken i the very end, after all of the elements have been discussed. Commissioner Noble indicated that the straw vote merely means that all of the questions have been answered and staff can move on to the next element. Chairman Savary assured the Commission and audience that no one would be denied the opportunity tc ask questions or express their opinion. Everyone will be exchanging ideas in an effort to come up with a satisfactory General Plan that will benefit all of the citizens of Carlsbad. Adrienne Landers, Senior Planner, reviewed the background of the request and stated that the City prepared, in conjunction with Cotton Beland & Associates, a Master Environmental Impact Report (MEIR to assess the environmental impacts that will result from implementation of the updated General Plan. T Master EIR assumed the worst case or that maximum buildout will occur in the year 201 0. This year wa! picked to avoid over-estimated long-term impacts. However, due to the present economic climate, buildout probably will not occur until after 201 0 so that actual development and associated impacts will probably be less than those identified in the EIR. The EIR is a program level document. It establishes mitigation programs through the General Plan policies and programs which were based on public input received during the public participation program and the review of the EIR. These programs will then be included as mitigation measures when later development projects come in. The EIR addressed all the usual issue areas and determined that impacts were mitigable in-all areas except air quality and circulation. In these two areas, the impacts were significant and cannot be mitigated by the City. Ms. Landers stated that air quality impacts cannot be mitigated for four reasons. As the City builds out a the population and workforce increases, air quality will be impacted due to increased gas and power consumption as well as vehicle miles traveled. These all result in increased air pollutants such as carbon monoxide. Due to the City's proximity to Interstate-5 and Highway 78, we will also experience regional traffic traveling through the City. Lastly, the City is located within the San Diego air basin which is presently a non-attainment basin and does not comply with State and Federal standards regarding air quality. The City has no jurisdictional control over either the through traffic or the San Diego air basin so while there are local impacts to air quality, it is really a regional issue over which the City has no control. However, the General Plan is proposing numerous programs to improve air quality and reduce traffic congestion. Some of these include roadway and intersection improvements, methods to reduce the number of daily trips, steps to address alternative modes of transportation such as bicycles and mass transit, and participation in regional strategies to improve air quality. However, even with these measures impacts to air quality will still be significant and unmitigable due to regional impacts which are beyond thc City's ability to control. Ms. Landers stated that circulation is the other area with unmitigable impacts. Again, as buildout occurs, there will be an increase in traffic volumes. Roadway segments will be adequate to handle buildout traffic however, 20 intersections will be severely impacted by regional through traffic over which the City has no jurisdictional control. These generally include freeway interchange areas and major intersections along Carlsbad Boulevard. Even with the implementation of roadway improvements such as striping and additional dedication, a number of intersections are projected to fail the growth management performance standards at buildout. The General Plan proposed a number of programs to address this issue. Included are policies to ensure that roadway facilities are in place when needed, programs addressing alternative modes of transportation (bicycles, trails and the commuter rail) which address not only circulation impacts but are also an attempt to improve air quality as well. There are programs to participate in regional growtl management and traffic congestion strategies, when finalized by SANDAG. Despite the City's best efforts, however, there are still significant unmitigable impacts due to regional through traffic which, again, the Cit cannot control. MINUTES PLANNING COMMISSION March 16, 1994 PAGE 3 I I I I Because the Master EIR has determined that there are significant and unmitigable impacts to air qual and circulation, the City is required by CEQA to provide a Statement of Overriding Considerations to the EIR. This has been provided in the EIR resolution which is part of the packet. It simply states tha impacts in these two areas are regional impacts requiring a regional solution. In accordance with Government Code, lhis statement is supported by findings which are also included in the resolution. introduced John Bridges, the EIR Consultant, and stated that he was available to answer questions 01 Master EIR and how it affects subsequent projects as they come forward. Commissioner Noblt! inquired if the reason it is difficult to control the traffic impacts is because a large percentage of it comes from Los Angeles. Mr. Bridges replied yes. There is evidence that a large am1 of transport smog affects the San Diego basin during certain times of the year. Commissioner Erwin inquired if the public will be allowed to speak on each separate issue, even thou! they may have spoken before. Chairman Savary replied yes. Chairman Savary opened the public testimony for the EIR and issued the invitation to speak. Marshall Krupp, President of Community Systems Associates, Inc., 730 El Camino Way, Suite 200, TI California, representing the Encinitas Union School District, addressed the Commission and stated th comments cross over EIR and Land Use, but he will only address EIR issues at this time. He referred Commission to page 5.1 2.7-1 which discusses education. In Section 5.12.7-3, it makes qualitative conclusions of the impacts of the General Plan on schools. It is his understanding that CEQA require! both a qualitative and quantitative analysis of impacts and there is no quantitative impact within the El There is no statemerit in the EIR of what the impact on schools will be. There is no statement on the number of students which will be generated, the number of facilities which will be required. However, Section 5.12.7-4 it states that there will be an impact on schools, regardless of the fact that there was quantitative analysis. It then states that the impact can be mitigated to a level of less than significant. Krupp contends that the EIR cannot conclude impacts can be mitigated to a level of insignificance if tt quantitative impact is unknown. Although the conclusion may be appropriate, it is not supported by tt' EIR documentation. Under mitigation measures (5.12.7-5) it then states that mitigation will be in conformance with the growth management plan, i.e. school capacity to meet projected enrollment witt the zone as determined by the appropriate school district must be provided prior to projected occupan This statement references Land Use Element section C-2. If you turn to the Land Use Element, the redlined strike out copy eliminates this provision. There is no longer any performance standard in the Use Element. So the EIR suggests a mitigation measure that is supposedly in the Land Use Element I the Land Use Element has eliminated the performance standard. Therefore, the mitigation measure is inappropriate. Finally, he stated that development fees under the statutory provisions of State law do I mitigate impacts to 61 level of insignificance which makes that mitigation inappropriate as well. Furthermore, Mello-Roos Community Facility Districts must be agreed to by the developer in question when he moves forward so that may not mitigate the impacts either. Mr. Krupp believes that, in additic air quality and circulation, schools should also be identified as not being able to be mitigated to a level insignificance. Ruth Besecker, Benchmark Pacific, 6670 El Camino Real, Carlsbad, addressed the Commission and stated that she had f'AXed over a letter dated March 16, 1994 which set forth her comments on the El She requested that her letter be entered into the record and become a part of the Minutes. She will thi make verbal comments during the public testimony period for the Land Use Element. Dolores Welty, 2076 Sheridan Road, Leucadia, speaking on behalf of Project Future, addressed the Commission and stated that considering the abundance of open space, rare, threatened, and endange natural resources, Project Future is astonished that this project states that only air quality and traffic w result in unmitigable impacts. All the mitigation is set aside for the future. She cannot see how there c be a finding that natural resources will be mitigated to a level of insignificance when there is no identification of what natural resources will be lost. Some of the natural resources to be considered an I 1 I I 1 I 1 I I 1 I I I I I MINUTES PLANNING COMMISSION March 16, 1994 PAGE 4 endangered species, threatened species, endangered habitats, vernal pools, sage scrub, three wetland riparian areas, etc. There isn't even a map which shows where these things are. She doesn't understa how the City can say they have mitigated for all of these resources when nobody has even defined whf they are located. Arto Nuutinen, 4920 Campus Drive, Newport Beach, California, representing the Carlsbad Unified Schc District., addressed the Commission and stated that his concerns overlap somewhat those made by Mr Krupp earlier. He referred to his letter dated March 16, 1994 which details his objections to the EIR ani the Land Use Element, and requested that the letter be entered into the record. In essence, the Districl concerned about approving an element of the General Plan which would allow the City to grant development approvals on affordable housing projects which would result in unmitigable facilities impa One of the bases for this concern derives from conclusions in the EIR which suggest that affordable housing is characterized by lower student generation rates than that of equivalent standard housing in community. In fact, the District alludes to certain findings of the consultant firm of Recht, Hausrath & Associates which indicates that affordable housing demographics are characterized by student genera rates in excess of what is normally characteristic of student generation in this community. He will makc available to staff copies of that report after he makes his comments on the Land Use Element. Mr. Nuutinen feels that the fundamental flaw of the environmental analysis is the supposition that there will a lower student generation. Commissioner Erwin referred to Section 5.12.7-3 of the EIR, second paragraph, which states that "...higher density affordable housing does not generate larger number of school-aged children than sir types of housing for the general population." He inquired if this is the statement that the District conter is in error. Mr. Nuutinen replied yes. That conclusion was based on certain findings involving certain census reports which were the same fundamental analyses which were used by the Recht, Hausrath report. He passed out pages 10-1 6 of the report for the benefit of the Commissioners. Commissioner Noble inquired if the survey was conducted in Carlsbad. Mr. Nuutinen replied that it wa taken in the Carlsbad area and surrounding communities. It was a two-tiered analysis. There being no other persons desiring to address the Commission on the EIR, Chairman Savary decla the public testimony closed and opened the item for discussion among the Commission members. Commissioner Schlehuber would like staffs response to the issues raised by the two school districts. Michael Holzmiller, Planning Director, replied that the performance standards for schools, referred to b Mr. Krupp, have been incorporated back into the Land Use Element (Errata #2). They were deleted in error. Staff used the Growth Management Plan as mitigation for schools because they felt that was the proper vehicle. In regard to the issue of affordable housing and student generation, he stated that this the first time he has seen the Recht, Hausrath study. Staff has not been aware of any studies or reseal which indicated that affordable housing projects generate more students than moderate income housin In fact, SANDAG prepared a study that compared bedroom size to low-income and moderate-income it concluded that there is no difference. Staff would have to disagree with the school district's conclusic based on the information they studied. Commissioner Erwin asked Mr. Holzmiller if "bedroom size" means number of children per s.f. of bedrc He replied no; that the study compared family size of one bedroom/low income with family size of one bedroom/moderate income. A total project comparison is not as valid as when the project is broken do into bedroom size. SANDAG's report concluded that there is no difference. Commissioner Erwin stated that he would like to read that report. Mr. Holzmiller replied that he did noi bring the report with him. Commissioner Schlehuber stated that Mr. Krupp was concerned about the conclusions in 5.12.7-4. Hc inquired if staff feels this has been remedied by Errata #2. Mr. Holzmiller replied that his understandin1 the speaker's comments was that it was significant but it is mitigable by the performance standard of MINUTES PLANNING COMMISSION March 16, 1994 PAGE 5 I I I I I I I I I I I I Growth Management. The copy of the Land Use Element which Mr. Krupp had showed those standa being deleted. Errata #E reinserts those performance standards so they are, in fact, a part of the Lam Element. commissioner Schlehuber would like to know if this reinsertion of the Growth Management performar standards would satisfy their concerns. Marshall Krupp, CSA, replied that this reinsertion does addre their concern because it now provides a mitigation measure. However, that doesn't resolve the fact tP EIR is still inadequate in defining what the environmental impact is. In essence, the mitigation measu mitigating something that has not been defined. The previous statement about level of significance is based upon the impact. When you read the language in the EIR, you cannot determine what the imp; As long as the performance standards are there, the school district is satisfied that there is a remedy t can use in order to ensure that the implementation of the General Plan will not impact the district. Th difficulty is that anyone who reads the EIR, once it has been certified, and once the General Plan has adopted, can come to the same conclusion that there was no definition of what the impact was. It is undefined at this point. In that case, the impact would have to be defined on every single project as it comes forward to the City Council. Commissioner Schlehuber believes this is a full protection because the school district has to, in effect, certify the impact. Mr. Krupp replied that once the performance standard has been reinserted into the General Plan, it satisfies his client's concern about impact mitigation. He is not sure, however, if it wil satisfy CUSD's concjern regarding affordable housing. Mr. Nuutinen, representing CUSD, stated that he was aware of Errata #2 and he recognizes that this provides a mitigation measure. His client's concern relates to the actual analysis in the EIR which stal that schools will be able to meet incremental growth in the community as it evolves. If that conclusion premised on what they believe to be inaccurate information regarding student generation, they cannol agree with it because they feel there may be a worst case scenario. Commissioner Schlehuber commented that even with the worst case scenario, the school district has hammer. Mr. Nuutirien replied that is true since affordable housing units will be pulled from the exces fund. However, the school district has not received confirmation that this is true with the General Plar Amendment. They want more clarification of the analysis so that they can point out where they disagi with the analysis. They just want to make sure that the policy established by the City Council will con1 I to be implemented. Commissioner Schlcthuber inquired if the school district would have no problem with the EIR if, in fact, determined that all housing is governed by the City's growth management plan and that affordable hoi must come from excess units. Mr. Nuutinen replied that even if the overall cap is met and excess unit! pulled from the excess unit reserve, the school district would still be impacted when certain regions art maximized. Their concern is that individual discretionary approval would still be allowed and could re: in the approval of uriits beyond the control points. Commissioner Schlehuber pointed out that even if that happens, the school district still has the hamm Mr. Nuutinen appreciates that reminder. Karen Hirata, Deputy City Attorney, requested that the study which Mr. Holzmiller referred to on stude generation for low income versus other types of housing be included as part of the record, even thougt did not bring that inlormation to the meeting. The Commissioners unanimously agreed to that inclusic Commissioner Hall stated that in the EIR we speak to Housing Program 4.1 of the Housing Element. 1 asked staff to explain Housing Program 4.1 (page 146) for the benefit of the audience. Mr. Holrmiller replied that one component of the adopted Housing Element was to see whether or not we should chai fee to non-residential commercial/industrial development to help provide affordable housing. It was I included in the work program for the Housing Element. The study has been completed by staff and is I MINUTES I I I I PLANNING COMMISSION March 16, 1994 PAGE 6 pending review by the City Council. They will make the decision on whether or not to go forward and direct staff to adopt a fee program. Commissioner Hall did not recall this program being adopted. Mr. Holzmiller replied that the adoption v to "study and consider" creating a non-residential fee to help provide affordable housing. In effect, a fe would be charged to commercial and industrial development, based upon square footage, that would tt go into the Housing Trust Fund and be used to provide affordable housing. The program to consider tt- type of a fee is part of the adopted Housing Element. After the Housing Element was adopted, the Planning Commission and City Council then approved a work program for all of the components in the Housing Element. That was one program which was included. Staff has completed the work and has drafted a report which is now pending consideration by the City Council. Commissioner Hall asked staff to explain the relevancy of Item #16 on page 2.05 under Air Quality. Jol Bridges, EIR Consultant, replied that this is needed to provide a balanced set of land uses in the community where people can have the opportunity to both live and work in the community to reduce vehicle miles traveled. This is a regional strategy to improve air quality and is an indirect connection. Commissioner Hall does not agree with that premise. He stated that it is used again in 5.5-4, Item #8. Bridges stated that section of the EIR deals with the impacts of increased population in the community i result of growth over time. The Housing Element programs are designed to address that increase in population because housing is needed to accommodate the population. It is one of a combination of programs suggested as mitigation. Commissioner Hall inquired if when we speak to 4.1 we are speaking to future jobs, i.e. increase in commercial and industrial activity. Mr. Bridges replied yes. Commissioner Hall stated that his next concern relates to the trail system. In his interpretation of the El document, it sounds as though the trail system is a sure thing. His understanding is that the trail syster only a proposal. In each element, it discusses the trail system. Only when you get to the Parks & Recreation element does it mention that the trail system is proposed. He thinks that the trail system shc be described as proposed throughout the entire document, Mr. Holzmiller replied that this is a valid poi The comprehensive Citywide trail system is subject to a financing mechanism. Commissioner Welshons commented that the two unmitigable points are air quality and circulation. If alternate methods of transportation are needed to mitigate the air quality, it seems that the trail system would be a high priority. Adrienne Landers, Senior Planner, replied that C-1 of the Open Space and Conservation Element is to establish a trail system, provided that financing is approved. All of the programs in the General Plan have been put into an implementing programs status chart that will be gii to the Council for consideration on a yearly basis. They will take that into account when they establish their annual goals and objectives and budget guidelines. That will be monitored and evaluated on the City's ability to fund it. Commissioner Betz referred back to Program 4.1 on page 5.3-8. Item #16 refers to an in-lieu fee for affordable housing. She questions the last sentence which states "...employer assistance to provide affordable housing for their employees." She doesn't understand why this is included in air quality. Mr Holzmiller replied that the idea is that if you have employees who qualify for affordable housing, and thc is no affordable housing in the City which causes them to live somewhere else, the distance between wl they live and where they work in Carlsbad is greater so it causes more air quality problems because the are more vehicle miles traveled. The idea is that if there is affordable housing in the City, and employec qualify for that, not only will they be able to work here but they will be able to live here, thereby shorteni the distance that they have to travel from home to work. Mr. Bridges pointed out that air quality is one of the significant unmitigable impacts so if some of these mitigation measures for air quality improvement seem like a stretch, they are intended to be. The City MINUTES PLANNING COMMISSION March 16, 1994 PAGE 7 i 1 1 I I I I I I I I I I I I needs to do everything they possibly can to improve the air quality situation, even though you cannoi mitigate it. What they have tried to do is identify any programs in the General Plan that offer an opportunity to reduce impacts to air quality. By doing that, you will have done everything you can, ai can then adopt a statement of overriding consideration. Commissioner Hall is concerned about the downside to this correlation. He understands where staff trying to go with this but he doesn't think it has been studied enough to be included in the General PI sounds like this is the sure method the City will pursue. He is not sure we have enough background l incorporate this. Mr. Holzmiller replied that he thinks the misunderstanding is that there is nothing in Housing Element or' EIR that says we have to adopt this type of program. All it is saying is that it sho studied and considered. If the City Council decides that there isn't that correlation, and they don't wa have non-residential contribute towards providing affordable housing in the City, it's okay to make th decision. It won't violate the General Plan or the EIR if, after considering it, they decide not to do it. Commissioner Welshons referred back to 5.5-4, Item #8, and stated that "The maintenance of a higt quality of life and a strong local economy ..." sounds like an oxymoron. She thinks it is a contradictioi when you follow it through and correlate it with the Housing Element, affordable housing, loss of ope space, etc. You can't have both things. Ms. Landers replied that these are goals in the Housing Eler which was adopted recently and approved by HCD. Commissioner Welshons stated that it still doesr make it right. Commissioner Noble doesn't think it is contradictory because the goal is to strive for those two things General Plan is only an outline of goals. Commissioner Welshons requested staff to address the mitigation measures for natural resources wh was brought up by Dolores Welty. Ms. Landers replied that biological resources are included on one maps in the General Plan. There are many policies and programs addressing habitat management planning efforts. Commissioner Welshons inquired if staff feels the concerns of that speaker have been addressed. MI Holzmiller replied that the two concerns were (1 ) that we didn't have anything showing where the sen resources are, and (2) that habitat protection was inadequately covered. He feels both issues have bt addressed because there is a vegetation map on page 5.4-2 showing a complete inventory of the hat the City and there are also numerous references to the habitat management planning efforts that the ( and the region are involved in. Chairman Savary inquired if the Commission is prepared to vote on the EIR. Adrienne Landers, Seni Planner, noted that the Planning Commission would be recommending certification of the EIR to the t Council. Commissioner Schlehuber commented that he believes the school district has some valid concerns bi does think the impacts have been mitigated. As to Project Future's concerns, he believes that the mal clearly states what is needed. Commissioner Hall's comment regarding the proposed trail should be included. In regard to the comments regarding the Housing Element and a possible tax on employen affordable housing,. Commissioner Schlehuber feels that since these are only goals, any action would be taken after significant public hearings and the tax may never happen. Someone will have to convii the City Council to do it and now it only gives them a tool to consider. He can accept the EIR with Mr. Hall's suggestion on any reference to the trail system. Commissioner Hall has strong objections to Section 4.1. He has stated these objections before and hc not vote in favor of the EIR as long as this wording exists. Chairman Savary requested Commissioner Hall to reiterate exactly what he objects to. Commissionei replied that wherever the EIR speaks to 4.1, it is speaking to a future tax on business. I I I MINUTE! 1 PLANNING COMMISSION March 16, 1994 PAGE a Commissioner Betz agrees with Commissioner Hall. She would like to see 4.1 deleted. Commissioner Welshons thinks the trails should be a flashing red light because it would help minimize circulation and air quality. Mr. Holzmiller suggested that a vote be taken on whether or not to strike 4.1 because it comes up agair the General Plan Amendment. The City Council has already directed staff to bring this forward. Wher they adopted the lnclusionary Ordinance, they promised residential developers that they would at least consider this aspect. That will go forward to the City Council, regardless of what is in the EIR. Howevr the issue is whether or not to believe that this is an adequate mitigation measure to reduce air quality, ! has already determined that air quality is unmitigable. He doesn't want the two issues confused. Commissioner Noble stated that if the City Council has final authority, he doesn't think any options sho be taken away from them. They could also force employers to urge employees to use alternative forms transportation. Commissioner Hall knows that the City Council has the final say but these are the driving documents. ACTION: Motion was made by Commissioner Hall, and duly seconded, to strike 4.1 wherever I referenced in the Environmental Impact Report. Chairman Savary, Commissioners Betz, and Hall Commissioners Erwin, Noble, Schlehuber, and Welshons VOTE: 3-4 AYES: NOES: ABSTAIN: None Chairman Savary called for a straw vote on the EIR. Commissioner Hall stated that he would cast his vote in favor of the EIR but he wants all documents wt go to the City Council to be extremely clear about his objection to 4.1. ACTION: Motion was made by Commissioner Schlehuber, and duly seconded, to recommend certification to the City Council of the Final Master Environmental Impact Report to tl City of Carlsbad General Plan Update dated March 1994 as presented, and that the system be asterisked throughout the document noting that it is subject to a funding mechanism. Chairman Savary, Commissioners Betz, Hall, Noble, Schlehuber and Welshons VOTE: 6-0-1 AYES: NOES: None ABSTAI N : commissioner Erwin Commissioner Erwin stated that he did not wish to cast his vote in the straw vote but he would vote whi the final motion is made. RECESS The Planning Commission recessed at 7:24 p.m. and reconvened at 7:36 p.m. Adrienne Landers, Senior Planner, addressed the Commission and presented the staff report on the General Plan. Using a slide presentation for the benefit of the audience, she reviewed the vision and tt eight elements of the General Plan. She stated that the last revisions to the Land Use Element Occurre 1985 to incorporate the Growth Management Plan. The present element has been extensively revised address numerous new topics, however the major changes affect commercial and residential land uses Many commercial designations have been redefined and some were consolidated. New policies were added addressing compatibility between commercial and residential land uses, including a provision fo MINUTES PLANNING COMMISSION March 16, 1994 PAGE 9 I B I I I I I I I I I I I I I I I commercial uses in master planned and industrial areas. The Element also focuses on programs to crt a stronger economic focus in the City. Policies were also added to require a full range of residential densities and stress the necessity of achieving minimum permitted densities. The Public Facilities Elen has also been integrated into the Land Use Element. Ms. Landers discussed the major issues of the circulation, noise, public safety, housing, open space and conservation, parks and recreation, and arts elements. Chairman Savary opened the public testimony and issued the invitation to speak. Ofelia Escobedo, 161 1 James Drive, Carlsbad, President of the Barrio Carlsbad Association, addressel Commission and thanked staff for including the Barrio in the Land Use Element. The Association has been working very dilligently to raise awareness of the Barrio and to enhance and improve the Barrio co m m u n i ty . Art0 Nuutinen, 4920 Campus Drive, Newport Beach, representing the Carlsbad Unified School District (CUSD), addressed the Commission and reiterated his previous comments regarding the environment analysis as part of the land use discussion. Although the General Plan contains a performance stand; which states that “sc11001 capacity to meet projected enrollment within each zone must be provided pri( projected occupancy”, there is no policy which ensures that public school facilities will be properly func The school fees presently authorized are not sufficient to ensure that school facilities will be adequate meet the needs of th’e community. CUSD is therefore seeking mitigation which would provide that assurance as part of the General Plan Update. CUSD also disagrees with the statement that affordabi housing provides fewer students than equivalent conventional housing. This premise by the City couli allow for approvals which result in density intensive zones that, even with the growth management cei would have physical environmental effects on the public facilities of the City, including schools. To ad this impact, CUSD would like to have the development condition which the Planning Commission and City Council have included in recent development approvals integrated as part of the General Plan I Amendment. Commissioner Erwin inquired if the mitigation that CUSD is seeking is to include in the General Plan agreement CUSD has with the City. Mr. Nuutinen replied that is correct. Even though each individuz project would contain the condition, they would also like to have it integrated into the General Plan. Chase Coman, 5855 Sunny Creek Road, Carlsbad, representing himself and his mother, Dorothy Ebi addressed the Comrnission and stated that he had written a letter dated March 11, 1994 which discus his reasons for being in attendance at this public hearing. Mr. Coman read the letter aloud and requc that it be included in the minutes. In his letter, Mr. Coman stated that his mother had received notice her 9+ acres might be affected by the proposed open space amendments to the General Plan. After reviewing the maps at the Planning Department, he discovered that most, if not all, of his mother’s pi would be classified iaS constrained. He met with Terri Woods and was advised that the constraints w the result of the 100 year flood plain and the creek which runs through his mother’s property. Howev Open Space and Canservation map is at odds with the Zone 15 LFMP Constraints Map which, he bel more accurately depicts the flood plain affecting far less of the site. He is concerned that a generaliz boundary on a map, even though it is incorrectly drawn, could eventually lead to a complete taking 0 mother’s property. Section 3.a. on page 10 of the March 16, 1994 staff report states that the map re\ pertaining to constrained lands do not depict precise boundaries. It further states that boundaries wil modified slightly in the future as more detail becomes available, Le. the tentative map process. The primary purpose of his letter is to state, for the record, that more than a slight modification to the ope space map presented this evening may be required to accurately reflect conditions on his mother’s property. He is also requesting an opportunity to meet with staff to revise the limits of the open spac designation affecting her property in order to reflect actual conditions prior to the City Council adopt the proposed General Plan Amendment. If that is not possible, he is requesting confirmation that sit specific studies will be required before the actual boundaries of the City’s open space zone is establi! I the area. MlNUTl PLANNING COMMISSION March 16, 1994 PAGE 10 Commissioner Noble inquired if he was aware of the Planning Commission memorandum dated Mar 1994. Mr. Coman was unaware of the memorandum. Commissioner Noble advised him that this memorandum states that staff has already made the changes you requested on the Open Space Mar Ms. Landers stated that she would see that Mr. Coman receives a copy of that memorandum. She confirmed that staff has met with Mr. Coman and the changes he requested have been made. Ruth Besecker, 6670 El Camino Real, Carlsbad, representing Benchmark Pacific, Fieldstone, and Ka Poinsettia, addressed the Commission and referred to her nine page letter dated March 16, 1994. Th entities own approximately 3,092 undeveloped acres of land which will be impacted by the proposed General Plan Amendment. She stated that the updated General Plan creates some potential conflict: which she would like to see remedied. Some of her concerns are as follows: - Noise Walls as a Last Resort - This requirement could prohibit many developers from meeting the ' minimum density requirement. Further, when the Habitat Management and Open Space plans are overlaid, they will create additional conflicts. She requested that a subcommittee be formed to disci some of the ambiguities and internal inconsistencies in the proposed General Plan Amendment. * 60 CNEL Noise Level - She noted that the noise level is stated at 60 CNEL instead of 65 CNEL. St was under the impression that 60 CNEL was only an interim policy to see how it worked until the Nc Element was updated. She feels this issue deserves more study and she renewed the same objectic that were discussed when the idea was first proposed. Some consideration needs to be given to are where noise levels cannot be controlled, i.e. properties adjacent to freeways, the rail corridor, and pr arterials. In the Arroyo La Costa project, for instance, if no walls or berms were allowed and 60 CNE was the standard, the project would lose 206 lots or 19% of its project. That would probably elimina the feasibility of the project from an economic standpoint. She realizes that the General Plan is only outline, however, rather than making a statement that is too specific when addressing noise mitigatic she would suggest wording such as "encourage attractive street scenes" as a possible alternative. . Minimum Densities - The staff report states that a developer would be required to show cause why densities thresholds could not be met and, in addition, would be required to process a General Plan Amendment. However, in the strike-out version of the Land Use Element, it appears that this may b discretionary rather than mandatory. Since there is an inconsistency here, she would like to go on record as objecting to a requirement for a General Plan Amendment. - South Coast Commuter Corridor - The language states that additional planning would be required d to emerging issues with SANDAG regarding densities in those areas, etc. Benchmark Pacific has recently purchased 3,000 undeveloped acres in that area and is the largest landholder. They are rea to start the application process. They are concerned that their application may be delayed significanl the City decides to require a comprehensive plan for the commuter corridor. She would like to see tl- language changed. + Two Year Review for Commercial Uses - It is next to impossible for a developer with a multi-phased project to secure financing from a lender if the project must be completed within two years. She woul like some reconsideration on that language. * Circulation - Fieldstone would like to request consideration in classifying Melrose, south of Rancho Santa Fe, to secondary arterial status. This subject is dealt with in detail in her letter but, basically, st is requesting that this decision be made now so that the debate does not continue into the future. * Open Space Element - She would like some thought given to how the Open Space Element related tc the Habitat Management Plan once it is implemented. She suggested the possibility of open space credits to create some flexibility. MINUTES >ORRECTED PLANNING COMMISSION March 16, 1994 PAGE 11 I I I I I I I I I I I I I I 1 I I Commissioner Erwin inquired about her feelings on 4.1 and non-residential entities helping to providt subsidized housing in the community. Ms. Besecker replied that Fieldstone participated in some extei research when the Housing Element was being created. She would agree that this issue needs to be Commissioner Erwin inquired if Arroyo La Costa can be built to 60 CNEL. Ms. Besecker replied that i using 6 ft. walls and berms. Commissioner Erwin stated that he would like to clear up a misunderstanding about the noise require1 Exterior noise can be as high as 70-75 CNEL but it must be mitigated to 60 CNEL. The interior firs story must be mitigated to 45 CNEL. The second story exterior could be 70 CNEL. Ms. Besecker understands these noise requirements. Dolores Welty, 2076 Sheridan Road, Leucadia, on behalf of Project Future, addressed the Commissic and stated that even though maps may be available, the boundaries have not been set. Project Futur hopeful that the Cornmission will set aside certain natural resources because the General Plan Amen does not give enough information as to how or if this will be supported. Neither does the General Pla Amendment identify a funding source so it appears that the hard decisions will be postponed until latl invites developers to develop first and the citizens will be left with the residual. She does not feel thal premise complies with community values and attitudes. The community has been outspoken in the n for open space and agricultural retention. Instead, the Plan allows major urban development. She w like to see a nexus of what can be mitigated to a level of insignificance. If a trail is mapped, it would t its placement in the future. Marshall Krupp, Community Systems Associates, Inc., 730 El Camino Way, Tustin, California, repres the Encinitas School District, addressed the Commission and stated that he is concerned that there a errors in the documentation. As an example, in Attachment #11 a school is identified at the El Camir Real and Rancho Santa Fe intersection and there is no such intersection. Other items he discussed as follows: - School Impacts -- He can accept the mitigation regarding performance standards as contained in 1 errata sheet prepared by staff. a Open Space - On page 29 of Attachment #26 and page 25 of Attachment #4, there is discussion ( space as it relates to schools. He is concerned that existing school sites are designated on the mi open space since it is a violation of State law, specifically Government Code 65852.9. (He providt copy of that language for the benefit of staff and the Commissioners.) The Encinitas School Distri opposed to the zoning of school sites as open space because it effectively devalues the property a a costly process to have the site rezoned. Furthermore, in Attachment #lo, the General Plan designation for Olivenhain Elementary School is being changed from RLM to E but under the zoni action it shows tlhat site as R-l-10,000 with no change. Mr. Krupp provided an errata sheet for consideration with wording that is consistent with State law. I studied further. a Mr. Krupp stated that he has prepared a letter to the Commission which he would like included in thl record. The letter was given to Mr. Holzmiller. Mr. Krupp apologized for submitting his material at I late hour. Commissioner Noble commented that there is nothing stated in the Land Use Element which requirc School District to rezone the property. Mr. Krupp replied that according to State law, a school site n designated the sarne as surrounding properties. In other words, it cannot be zoned as open space. Commissioner Schlehuber suggested that perhaps staff should consider using the "Unplanned" zon school sites. Michael Holzmiller, Planning Director, replied hat if a site has been purchased or ther has always zoned proposed school sites as open space until it is either purchased by the school disi MINUT school on it, it is designated in the General Plan as a schoo 1 site. However, for the past 15 years. C ZORRECTED PLANNING COMMISSION March 16, 1994 PAGE 12 a school is built on the site. The school district doesn't have a problem with the General Plan designatic They only have a problem with the zoning. This law may have been created after all of the school sites were rezoned about 15 years ago. Karen Hirata, Deputy City Attorney, disagrees with Mr. Krupp's assessment and how it applies to what tt City is doing here. In her opinion, the City is doing nothing illegal here and it hasn't been doing anythinc illegal in the past. This code section states that the City cannot "rezone" a site to open space prior to thc sale. If the school district were trying to sell a site for a goodly sum, the City could not come along and rezone the site to open space just to stop the sale of the property. This is not what we are doing; the school sites are not being rezoned. Mr. Krupp believes that zoning school sites as open space is inconsistent with this government code section because it clearly states that the land use designation must be compatible with surrounding land uses. He believes there is no reason to zone a school site as open space unless the City desires to purchase that site at a devalued price if it became available for sale. Ms. Hirata disagrees with Mr. Krupl &$hfipfibh legal analysis. Commissioner Erwin inquired if this reasoning is because the school district wants to get the highest zoning possible in the event of a resale. Mr. Krupp replied no; it is actually more related to the school's asset management program. Commissioner Erwin inquired if this is so the property could be sold and developed into a large apartmer complex. Mr. Krupp replied no. If R-1 is the surrounding zoning, then the school site should be R-1 as well. Commissioner Erwin understands that when a school is built, the site is usually provided by the develope and the State provides the rest of the money. Mr. Krupp replied that is not correct. There is a 5040% program as well as a 100% program. The State doesn't always put up all the money and developers are not required to dedicate property for a school. They are required to pay a fee. However, Carlsbad has greater leverage as a result of the Growth Management program. Some developers have dedicated land lieu of school fees. Commissioner Erwin inquired when a school is sold that was built under the 50-50°/0 program, does the State get back 50% of the money. Mr. Krupp replied that if a school is undercapitalized, the State sometimes waives this requirement. If a school is under capacity, the State may require payment. The actual amount would be negotiated. Wesley Radoycich, 2620 El Aguila Lane, Carlsbad, addressed the Commission and stated that he represents the Friends of Carrillo Ranch. The proposed Highway 680 was cancelled due to environment: problems. The Friends would like to recommend that the Melrose Avenue link from Palomar Airport Roac to Rancho Santa Fe Road be greatly downgraded or, preferably, deleted from the Circulation Element of the General Plan. Otherwise, the huge amounts of traffic on Melrose will create a traffic bottleneck that would injure the delicate Carrillo Ranch. Mr. Radoycich's remarks were submitted to the Minutes Clerk fc inclusion in the record. Bob Ladwig, 1947 Camino Vida Robles #108, Carlsbad, representing MAG Properties, addressed the Commission and stated that his client is concerned about the two year review on commercial properties since the development of commercial properties normally has to wait for development of the surrounding area. Many times this takes up to four years for an area to fully develop. He requested consideration in having that language deleted or amended. Richard Chick, 2775 Spokane Way, Carlsbad, representing Joe Sherman, addressed the Commission anc stated that his client owns 96 acres in the northwest quadrant adjacent to the South Coast Asphalt Plant on Highway 78. The proposed General Plan shows a split land use designation on this property with a MINUTES PLANNING COMNllSSlON March 16, 1994 PAGE 13 I 1 I I 1 I I I I I I I 1 1 I I I I I large portion designated as open space. He stated that the delineation of open space depends on th future alignment 01 Marron Road. Therefore, he requested consideration in having the land use designation remain in its present state rather than the designation which has been proposed. Margie Monroy, 361 0 Carlsbad Boulevard, Carlsbad, representing the League of Women Voters, addressed the Commission and congratulated staff for producing a user-friendly document that is e understand. However, she.believes that some of the errata strike out changes make the document I clear. For instance, on page 39 the strike out portion shows growth management as being deleted. inquired if the errata corrected that situation. Ms. Landers replied that it did. Ms. Monroy commentt the City Library did1 not have that correction in their version. Ms. Monroy stated that the League war people to have all of the facts before the public hearing. She thinks there is a problem bringing this of a document forward at one time unless all of the material is available for public review well in advi the hearing. One rnajor item that the League is interested in is the Housing Element. She realizes tl was adopted in 19!32 and it is coming up again in 1994 with no changes. However, in 1992 the 199( census figures were not available and they are now. She would like to have those census figures inc Those figures are used in the Parks & Recreation Element and she thinks the document should be consistent. She would also like to know if efforts are being made to do a housing inventory rather th solely on the census. Also, in Section 3 she doesn't see any mention of constraints regarding afford housing and neighborhood negativeness. She inquired if something should be said about that and i are ways to mitigale this problem. Commissioner Welshons commented that she had recently attended the Planning Institute Conferen one thing they stressed was to make sure that data is consistent. She appreciates Ms. Monroy's con regarding the 199CI census data. Dan Downing, 7254 Mimosa, Carlsbad, addressed the Commission and stated that the proposed Ge Plan takes Carlsbad into the 21st century. If it is done right, our children will have a wonderful place live. If it is done wrong, they will be the ones to pay the price. He hopes the Commission will take th consideration. He feels we need a new vision because in the 21 st century cars will be a thing of the I He thinks we need to modify the plan and promote alternate methods of transportation. He thinks wt to plan now for rights-of-way for public transportation rather than wait until later when we have to te down buildings. Commissioner Noble inquired if Mr. Downing was aware of the plans for the commuter rail from &e to San Diego and IEscondido. Mr. Downing replied that he doesn't think the proposed General Plan addresses that very well. Commissioner Erwin inquired if Mr. Downing is advocating the setting aside of rights-of-way now fc future. He replied yes. Commissioner Erwin inquired if he is suggesting that we leave properties in their natural state. Mr. Downing replied no. He thinks we need to include plants and drip irrigation. We also need to addre' habitat issues. Larry Lamb, 4669 'Woodstock, Carlsbad, representing himself and the Cape at Calavera Hills Homeo Association, addressed the Commission and stated that he is concerned we are giving preferential treatment to new development at the expense of existing residents. If this is the case, then somethin! wrong with this City. He moved here from Los Angeles to get away from the walls. Now College Boulevard is being approved with walls. He has talked about this on numerous occasions. He is not talking about mitigation. He is talking about the realignment of College Boulevard. In some cases, C Boulevard will be only 18 ft. away from the existing homes. He urged the Commission not to make 11 mistake at the expttnse of existing residents. MINUTE PLANNING COMMISSION March 16, 1994 PAGE 14 Don Friedlander, 2245 Nob Hill Drive, Carlsbad, addressed the Commission and stated that in looking i the EIR, he sees an area of noise mitigation which has been overlooked. That is the noise of aircraft in City of Carlsbad. The proposed General Plan seems to address the concerns of airport noise in terms ( the areas immediately surrounding the airport. The landing pattern runs east and west, however the flii pattern for aircraft from Los Angeles runs the entire breadth of the City. He realizes that the City has nc direct control of aircraft because the airport is controlled by the County. Mr. Friedlander would like to s some controls on aircraft-generated noise in the City. He thinks existing residents have the right to enj quiet. Commissioner Erwin inquired if the aircraft noise he is referring to comes from twin turbo props. Mr. Friedlander replied yes, that it is mostly from commercial aircraft. He feels the noise will be 40% worse buildout but it depends on where the San Diego airport is moved to. Ernestine Graves, 4620 Buckingham Place, Carlsbad, addressed the Commission and stated that she I at Tamarack Pointe. She has called the City several times to complain about the aircraft noise. She al has a problem with barking dogs. Caroline Prescott, 4669 Woodstock, Carlsbad, addressed the Commission and stated that she likes the proposed General Plan but she is concerned about College Boulevard and the setback requirement for walls. She would like to see trees planted along streets with a lot of traffic. It would also protect the wal from graffiti artists. She is concerned that the wall along College Boulevard will be a great target for graffiti. She also has a problem with barking dogs in her neighborhood, but she has never found airpor noise to be a big problem. She loves being able to fly out of Carlsbad. Lastly, she would like to know if powerline easements were considered due to the public controversy about EMF. Commissioner Welshons inquired how the College Boulevard realignment will affect her. Ms. Prescott replied that the proposed College Boulevard will bring a tremendous amount of traffic into her neighborhood. Her father used to be on the Planning Commission and he told her that when that alignment was created there was never a plan to place business uses in the residential area. Albert Benguiat, 2947 Lexington Circle, Carlsbad, addressed the Commission and stated that he has hti many problems with barking dogs in his neighborhood. He brought along a tape recording made in his bedroom if anyone was interested. He asked the City on numerous occasions to look into the problem. The County of San Diego has an Office of Noise Control. They send a warning letter and if the problem continues, the District Attorney's off ice files a misdemeanor complaint against the offender. If convicted the offender can be fined up to $1,000 for each count or they can be sent to jail. He thinks the City of Carlsbad needs an effective process to deal with barking dogs. He will continue to complain until the process is improved. Karen Hirata, Deputy City Attorney, replied that Mr. Benguiat has written numerous letters to the City an staff has spent a great amount of time investigating the problem. She feels that our ordinance is adequ: and staff does not recommend any changes. Mike Howes, Hofman Planning Associates, 2386 Faraday, Carlsbad, addressed the Commission and stated that he hopes the Planning Commission will adopt 65 CNEL as the standard because it is extremi difficult to meet the 60 CNEL requirement. It means the difference between a 6 ft. wall and a 10 ft. wall. Berms eat up land. For instance, a 6 ft. berm requires 27 ft. of developable area. In order lo mitigate Rancho Carrillo to 60 CNEL, it will require 10-1 2 ft. walls or 125 ft. setback. Many cities use 65 CNEL along freeways and major transportation corridors. Commissioner Erwin asked staff what the consultant recommended for the CNEL. Terri Woods, Associi Planner, replied that staff originally suggested 65 CNEL but the noise consultant recommended 60 CNE MINUTES PLANNING COMMISSION March 16, 1994 PAGE 15 1 I I I I 1 I I B i I I B I I I I Commissioner Erwin stated that a survey was taken in 1990 and a number of cities use 60 CNEL. t believes that 5 dBA is a significant amount of noise. Mr. Howes concurred that 5 dBA is when you ( notice the difference. Paul irisari, 181 7 tianscomb Drive, South Pasadena, addressed the Commission and stated that he representing the owners of property located in the southeast corner of Laurel Tree Lane and Palom: Airport Road. Under air quality and circulation, mitigation calls for limited access on high use road: as Palomar Airport Road. However, he is concerned that historical access be preserved. The propc is speaking to is served by Laurel Tree Lane, which has and can provide future access to the proper would like to make sure that historical access is not denied, particularly in areas where access may denied because the arterial is an important one and the deceleration lanes are extreme. He contenc if other access is denied from important arterials, then secondary access should be assured. Bob Ladwig, 1947 Carnino Vida Robles #108, Carlsbad, representing MAG Properties, addressed tt Commission and stated that this is the first time he has seen the exhibit which was handed out rega potential alternatives, Program C.12. As he understands it, if commercial sites are within a Master ( Specific Plan, they will be exempt from the periodic reviews. If that is correct, he would be satisfied that.

The Addendum has been prepared in accordance with the Califor Environmental Quality Act (CEOA) of 1970 (Public Resources Code Section 21000 et seq.) and Guidelines for the lrmplementation of CEOA (California Administrative Code Section 15000 et se The City of Carlsbad (hereinafter referred to as the "City") completed its draft General Plan in Febru 1993. The Final Master EIR evaluates the environmental effects of adopting and implementing General Plan, and establishes a mitigation monitoring program. The General Plan EllR fulfills the provisions for a Master EIR established in Section 21 156 of the Pu Resources Code. The Master EIR evaluates a broad range of potential environmental impa associated with the! long-term implementation of the Carlsbad General Plan. The Master EIR allc consideration of broad policy alternatives and programmatic mitigation measures. The degree specificity used to analyze the potential adverse environmental impacts in the Master EIR is relate( the broad nature of the policy recommendations contained in the General Plan. The Master includes the same contents presently required for all ElRs plus a description of anticipated subsequ projects that are within the scope of the Master EIR. The Master EIR will serve as the basis environmental review and impact mitigation for subsequent projects. The Draft General Plan and Master EIR were distributed to public agencies and other interested par for public review in accordance with the requirements of CEQA and state planning law. Wril comments on the (draft documents were solicited and public hearings were held to receive vel comments. Based on the comments received, the City has made several minor modifications to General Plan as outlined in Exhibit "A" of this Addendum. 1.2 Leaislative Authoritv The Addendum to the Final Master EIR is authorized by Section 15164 of the CEOA Guidelines. Addendum is allowed under specific circumstances where, in order to comply with CEQA, the requires "minor technical changes or additions" that "do not raise important new issues about significant effects on the environment," and where no factor is present that would require preparation of either a subsequent or supplemental EIR. (CEOA Guidelines Section 15174 (a).] Addendum is a tool to make minor corrections in ElRs without recirculating the EIR. The CE Guidelines allow the Addendum to be included in or attached to the Final EIR. The decision-mal body must consider the addendum along with the Final EIR when making a decision on the propc project. The minor changes made to the Carlsbad General Plan do not alter the conclusions of environmental analysis in the Master EIR. No additional environmental effect will result from changes. Additionally, mitigation measures in the Master EIR have been modified if necessari accommodate the !slight changes in the General Plan. 1 I ADDENDUM FINAL MASTER Environmental Imroact ReRort CITY OF CARLSBAD The minor changes to the Land Use Plan do not constitute any of the conditions requiring the preparation of either a subsequent or supplemental EIR. According to Section 151 62 of the CEOA Guidelines, a subsequent EIR or supplemental EIR is required only under the following conditions: 1. Subsequent changes are proposed in the project which will require important revision of the previous EIR due to the involvement of new significant impacts not considered in the previous EIR. 0 The minor changes to the Carlsbad General Plan will not change the conclusions of the environmental analysis in the Master EIR. 2. Substantial changes occur with respect to the circumstances under which the project is undertaken which will require important revision in the previous EIR due to the involvement of new significant environmental impacts not covered in the previous EIR. 0 The environmental circumstances under which the Carlsbad General Plan will be implemented have not changed. The modifications to the General Plan will not cause the environmental circumstances to change and no new environmental impacts will result. - 3. New information of substantial importance about project impacts, feasible mitigation measures or alternatives has become available. 0 No new information about the impacts of the Carlsbad General Plan, additional feasible mitigation measures or alternatives has become available.

An updated draft General Plan WE completed in February 1993 and serves as the project that is the subject of this EIR. This Master El has been prepared in accordance with the California Environmental Quality Act (CEQA) of 1970 (Pub1 Resources Code Section 21 000 et seq.), the Guidelines for Implementation of CEQA (Californ Administrative Code Section 15000 et seq.), and Title 19 of the Carlsbad Municipal Code. The update and amendment of a general plan constitutes a project for the purposes of the CEQA ar the State CEQA Guidelines. This Master EIR is designed as an informational report and is not a Ci policy document. It is intended for use by the City decision makers, any federal, state and loc jurisdictional public agencies and the general public. The document provides information regarding tt potential environmental impacts related to implementation of the updated Carlsbad General Plan. TI purpose of the Master EIR, under the provisions of CEQA, is "to identify the significant effects oi project on the environment, to identify alternatives to the project, and to indicate the manner in whi these significant effects can be mitigated or avoided" (Public Resources Code Section 21 002.1 (all In accordance with the provisions of the CEQA Guidelines, this EIR is prepared as a Master EIR. T provisions for the Master EIR were established in Assembly Bill 1888 which was signed into law October 1993. The bill was written for the purpose of streamlining the CEQA process and authori the use of a Master ElR to: 1) allow complex and controversial environmental impacts to be analyzi and addressed early in the CEQA process; and 2) reduce or eliminate subsequent, redundant analy! of environmental impacts. According to AB 1888, general plans are appropriate subjects for Mas1 EIRs. The provisions; of the Master EIR are identified in the CEQA Guidelines as of January 1, 19! in Section 21 157 of the Public Resources Code. This Master EIR evaluates a broad range of potential environmental impacts associated with long-tei implementation of the Carlsbad General Plan and allows the City to consider broad policy alternativ and programmatic mitigation measures. The degree of specificity used to analyze the potential adver environmental impacts in the Master EIR is related to the broad nature of the policy recommendatia contained in the updated General Plan. This Master EIR includes the same contents presently requir for all ElRs plus a description of anticipated subsequent projects that are within the scope of t Master EIR. The Master EIR serves as the basis of environmental review and impact mitigation * subsequent projects I 1.2 Master EIR Use This Master EIR h;is been prepared to assess the environmental impacts that will result fr implementation of the updated Carlsbad General Plan. The EIR is a program-level document t identifies significant impacts for a variety of issues and establishes program-level mitigation rneasu to effectively reduce significant impacts. The mitigation measures consist of General P implementation policies and programs. Many of the program-level mitigation measures will reqi further refinement as the project-level impacts of subsequent projects and appropriate project-le mitigation measures are determined. This Master EIR contains the same contents presently required for all ElRs plus a description anticipated subsequent projects that are within the scope of the Master EIR. Once a propo! Purpose of the Master EIR I NTRO DUCT10 N 1 .o- FINAL MASTER Environmental ImDact ReDort subsequent project of any type is filed with the City of Carlsbad, the City will determine whether or not the subsequent project is identified in the Master EIR. If a project is not identified in the Master EIR as a subsequent project, then an Initial Study is prepared pursuant to CEQA and a Mitigated Negative Declaration, or a Subsequent or Supplemental EIR is prepared to update the Master EIR. If a project is identified in the Master EIR as a subsequent project, an Initial Study is prepared. With the Initial Study the City then determines whether or not the significant environmental impacts of the subsequent project are addressed by the Master EIR. If the City can make the following findings based on the results of the Initial Study, no further environmental review is required: The subsequent project is within the scope of the Master EIR; The project will not cause any additional significant effects on the environment not described in the Master EIR; and No new or additional mitigation measures or alternatives are required to mitigate the subsequent project's significant environmental impacts. CITY OF CARLSBAD 0 0 0 Should the City determine that the subsequent project may cause significant environmental impacts not addressed in the Master EIR, either a Mitigated Negative Declaration, an EIR, or a focused EIR is prepared. A focused EIR may be prepared for a subsequent project if the City determines that the Master EIR's analysis of cumulative impacts, growth inducing impacts, and irreversible significant effects on the environment is adequate for the r .bsequent project. The diagram below describes the environmental review process for subsequent prUjects filed with the City of Carlsbad after certification of the Master EIR.

The EIR provides a program-level analysis examining the overall effects of the land u: and development intensities established by the updated General Plan. 2.2 Projt!ct Location The updated Carlsbad General Plan applies to areas within the City limits which encompa approximately 42 square miles. The City is located along the Pacific coast in northern San Die County. San Diego is the most southwesterly county of the continental United States and is locat north of the Mexican border. Carlsbad is bounded by the City of Oceanside to the north; the City Encinitas to the south; the Cities of San Marcos and Vista and unincorporated County areas to 1 east; and the Pacific Ocean to the west. 2.3 m?ct DeveloDment Characteristics The objective of the updated General Plan is to establish definitive guidelines and policies which L allow for orderly, efficient, and sustained growth in the City of Carlsbad. Through implementation these goals and policies, the City will work toward providing a pleasant living and working environmc while conserving and maintaining the natural physical environment to the greatest degree possiblt The updated General Plan consists of the following seven mandatory elements that fulfill the State la related to city planning as well as two optional elements: I I I I I 1 1 I I I I I I I I I EXECUTIVE SUMMARY 2.0- I I Land Use Circulation Open Space and Conservation (combined) Noise Safety Housing Parks and Recreation (optional) Arts (optional) In terms of physical development of the City, the General Plan Elements of most significance are t Land Use and Circulation Elements. The Land Use Element provides for the ultimate development 52,638 dwelling units and 58.3 million square feet of non-residential uses. The Land Use Elemt incorporates the City’s Growth Management Plan. The number of new dwelling units allowed by t Land Use Element is somewhat less than the maximum number of units allowed by the Grov Management Plan dlue to recognized environmental constraints. The Circulation Element provic transportation improvements to accommodate the planned development. The other elements COnti programs and policies to preserve environmental quality as development proceeds according to t Land Use Element. FINAL MASTER Enwkonmenfal Impact ReDort 2.4 Environmental Impacts The City of Carlsbad determined that an EIR should be prepared for the updated General Plan pursuant to the CEQA Guidelines. The environmental issue areas identified in the Initial Study for assessment in the EIR include: CITY OF CARLSBAD Soil and Geology Hydrology Noise Air Quality Biological Resources Aesthetics Population/Housing Utilities and Public Services Land Use Natural Resources Circulation Cultural and Paleontological Resources Health, Safety, and Nuisance Factors The impact assessment in this Master EIR assumes that maximum buildout will occur at 2010. This maximum development scenario is used in the analysis to avoid underestimation of long-term impacts. The environmental impact analysis in this document is based on the change between development conditions existing in 1990 and those projected for the maximum development scenario in 2010. Many of the technical reports employed in this Master EIR rely on 1990 environmental conditions and this base year is consequently used throughout the Master EIR to provide a consistent analysis. Actual buildout of the General Plan, however, will most likely not occur until after 2010 due to regional economic conditions. As a result, the actual development and associated environmental impacts at 2010 will most likely be less severe than the environmental impacts identified in this Master EIR. A summary of the environmental impacts of the proposed project, cumulative impacts, and required mitigation measures is provided in Table 2.0-1 : Environmental Impacts and Mitigation Measures. See set, 9.0: Growth-inducing impacts are also assessed in the EIR. Adoption of the Carlsbad General Plan will not Response TT result in significant growth-inducing impacts. The General Plan will not cause growth but rather it is an approach required of cities and counties by the State of California to accommodate, manage, and control growth. 2.5 Potential Siqnificant Impacts Based on the data and conclusions in this EIR, the City finds that the proposed project will result in significant cumulative air quality and circulation impacts due to daily regional through traffic utilizing City of Carlsbad roadways which cannot be fully mitigated. Implementation of the mitigation measures outlined in this document can reduce all other impacts to a level of less than significant. 2.6 Potential Areas of Controversy CEQA Guidelines require potential areas of controversy to be identified in the Executive Summary. The following items may generate public controversy during project implementation: 0 0 Land use density and intensity standards; Providing for an appropriate range of housing to ensure adequate number of affordable housing; Designation of areas to be preserved as open space; and Development constraints due to the federal listing of the California gnatcatcher as threatened. 0 0 2.0-2 EXECUTIVE SUMMARY FINAL MASTI ' CITY OF CARLSBAD Environmentaf fmoact Rem ' 2.7 - Alternatives to the ProDosed Proiect The alternatives evaluated during the analysis of the proposed project include: 0 0 Existing General Plan 0 Decreased Residential Development 0 Density Transfer No Project (i.e. no further development) 1 i 8 1 8 1 I 1 1 I D I I 1 b EXECUTIVE SUMMARY 2.0-1 I The No Project and Decreased Residential Development alternatives are environmentally superior to 1 proposed project bun implementing these alternatives is infeasible. Table 2.0-2 provides a cornparis of the impacts of the proposed project and the four alternative projects. I ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES I. Unavoidabte Significant Environmental Impacts (Lead Agency must issue "Statement of Overriding Considerations" 'under Section 15093 and l5126@) of 'the State CEQA Guidelines if the agency determ these effects are significant and wishes to approve the project). AIR QUALITY Potential Environmental Impact As development proceeds, emissions from mobile sources (e.g., can. trucks, buses) and stationary sources (power use and commercia light industrial development) will increase. In addition, several intersections will be significantly impacted by General Plan buildout i carbon monoxide "hot spots" may occur periodically. Implementation of the General Plan will require new construction projects whii produce short-term air quality impacts. Although the City will implement measures to reduce the generation of emissions, the cumu impact cannot be mitigated to less than significant. The San Diego Air Basin is a non-attainment basin and any additional air emiss are considered significant. Mitigation Measures Planned Land Use Pattern 1. Development applications should contribute to and extend existing systems of foot or bicycle paths, equestrian trails, and the greenbelts provided for in the Circulation.

State law requires the General Plan to address issues influencing land u decisions, circulation, housing, conservation of natural resources, preservation of open space, the noi environment, and the protection of public safety. These issues are addressed in the seven mandatc General Plan elements required by State law (California Government Code, Section 65300 et. seq Two of these elements have been combined in one element, Open Space and Conservation. Optior elements have been prepared by the City to address other important issues. The following I identifies the mandatory elements and the optional elements of the Carlsbad General Plan: MANDATORY ELEMENTS OPTIONAL ELEMENTS Land Use Parks and Recreation Circulation Arts Open Space and Conservation I Noise Safety I Housing The General Plan is to be used as a guide for the City's future growth and each element addresses t City's philosophy and approach toward that particular component of City development. The Gene Plan establishes the maximum level of development that can occur within the City. This Master E therefore, analyzes the environmental effect of maximum development scenario (or "buildout") of t General Plan. The maximum development scenario consists of the construction of the greatest squ: footage and number of dwelling units allowed by the General Plan for residential and non-residenl land uses, respectively. The maximum development scenario also identifies the maximum populati expected to inhabit the City. The impact assessment in this Master EIR assumes that maximum buildout will occur at 2010. TI maximum development scenario is used in the analysis to avoid underestimation of long-term impac The environmental impact analysis in this document is based on change between developmf conditions existing in 1990 and those projected for the maximum development scenario in 201 Many of the technical reports employed in this Master EIR rely on 1990 environmental conditions a this base year is consequently used throughout the Master EIR to provide a consistent analysis. Acti buildout of the Genleral Plan, however, will most likely not occur until after 2010 due to regioi economic conditions,. As a result, the actual development and associated environmental impacts 201 0 will most likely be less severe than the environmental impacts identified in this Master EIR. 3.2 The City of Carlsbad is located along the Pacific coast in northern San Diego County, as shown on M 3.2-1: Regional Location. San Diego County is the most southwesterly county of the continen United States and i.t is located north of the Mexican border. Carlsbad is bounded by the City Oceanside to the nlorth; the City of Encinitas to the south; the Cities of San Marcos, Vista E unincorporated County areas to the east; and the Pacific Ocean to the west.

All land within the State-approved "sphr of influence," including all unincorporated "county islands", have been annexed into the City. A! result, the Carlsbad incorporated area is not expected to expand in the future and growth will occ within the current boundaries. The City contains three Uagoons, extensive agricultural lands, and la1 tracts of undeveloped land. 3.3 Background The City of Carlsbad incorporated in 1952 and adopted its first General Plan in 1965. In 1975, 1 General Plan was revised pursuant to new State requirements and several optional elements WE added to address other City issues. Since its adoption, several General Plan elements have be revised and amended. In 1985, the Circulation, Housing, and Land Use Elements were updated a the Arts and Historic Preservation Elements were added. Recent changes include revisions to the Par and Recreation, Housing, and Open Space and Conservation Elements. The City has elected to upd: the entire General Plan to address the changing conditions, circumstances, and policies within the C of Carlsbad and the San Diego region. The updated General Plan contains the most current technic information and is consistent with all applicable State legislation. I 3.4 Project Obiectives The objective of the General Plan is to establish definitive guidelines and policies which will allow 1 orderly, efficient, andl sustained growth in the City of Carlsbad. Through implementation of these go, and policies, the City will work toward providing a pleasant living and working environment for C residents and workers, while conserving and maintaining the natural physical environment to t greatest degree possible. 3.5 Project Characteristics m 3.5.1 -- Vision The General Plan contains a vision for the City and the vision guides the General Plan goals ai objectives. The vision constitutes aspirations and values for the City's ultimate buildout as well performance standards by which to measure the City's progress. The vision for the City is summariz below. 0 A City which provides a balanced variety of land uses for living, business, employmer recreation, and open space. A City which offers safe, attractive residential areas with a wide range of housing typt styles, and price levels in a variety of locations. A City which balances the diverse living, playing, and working needs and services of the fo sub-communities within the City. A City which provides a diversified, comprehensive park system that offers a wide variety recreational activities and park facilities. A City where travel is safe and easily accommodated whether it be by mass transit, in i automobile, on a bicycle, or as a pedestrian. 0 0 0 I I 0 1 PROJECT DESCRIPTION 3.0-: I CITY OF CARLSBAD 2 \ \ MAP 32-2 3.0-4 FINAL MAS1 EnvironmentaI Impact Ref CITY OF CARLSBAD i D i il i 1 I I I I I I I I I I 0 A City committed to the economic growth of progressive commercial and industrial busine to serve the employment, shopping, recreation, and service needs of its residents.

The General Plan elements provide the neces: link between the Ciity vision and the long-term realization of the vision. The elements contain gc policies, plans, andl programs for their implementation. The implementation programs for indivi elements also serve to mitigate anticipated environmental impacts. In terms of guiding physical development of the City, the General Plan elements of most significa are the Land Use arid Circulation Elements. These elements will guide the City's physical growth I 2010. Other elerrients of the Plan contain specific provisions for the general health, safety, welfare of residents and for the conservation of natural resources as the City continues to deve More specifically, the Land Use Element establishes an appropriate distribution and intensity of 1 uses and is created to maintain residential densities within desired ranges. It also permits developrr and intensification of office, commercial, and industrial uses in specific areas of the City wt infrastructure and surrounding uses are designed to accommodate these uses.

The Element indic: where road construction and improvements (widenings, realignments, and intersection enhancemei will occur and when they will be completed over time as new development occurs. The Circulal Element also contains goals, policies, and implementation programs for alternative transportation (e mass transit, bicycles, pedestrian uses). The Open Space and Conservation Element coordinates and guides decisions related predominantl, the undeveloped land and water surfaces which define the physical environment of Carlsbad. Open Space portion of the element serves as an official policy statement for the identificat preservation, conservation, and acquisition of trails and open space in the City. The Conservai portion provides guidelines for resource management and includes guidelines to prevent exploitati destruction, and neglect of natural resources.

The element establishes noise and land use compatibility standai and guidelines for incorporating noise barriers and mitigation measures into development project desi( The Public Safety Element identifies natural and man-made hazards which may pose a potential thrf to the general safety and welfare of City residents and businesses. The element requires that put safety be considered in the planning and decision-making process to reduce the risk of injury, loss life, and propew damage associated with the identified hazards. The major areas of concern foc on emergency services (fire protection, police, medical), fire, flood, geologic hazards, and hazardc waste management. The Housing Element is intended to provide residents and public officials of Carlsbad with informat about community housing needs and to develop an integrated set of goals, policies, and programs assist the community in meeting those needs. State law requires that Housing Elements be upda every five years; the Carlsbad Housing Element was conditionally approved by the State of Califor Department of Housing and Community Development in June 1992 and subsequently certified on h, 19, 1993. The two optional element in the updated General Plan are the Arts Element and the Parks i Recreation Element. The Arts Element recognizes that the arts contribute to the cultural and aesthc environment of the City and that the City should create a climate that encourages artistic developme The Parks and Recreation Element identifies the methods that will be used to plan, develop, i provide quality active and passive park facilities and recreational programs. The element ensures t Carlsbad residents, tourists, and employees are afforded enjoyable leisure experiences. 3.5.3 - Growth Manaaement Plan Public facilities and services must be expanded and extended as new development occurs within City to maintain the quality of life for residents. To ensure that adequate public facilities and servi are guaranteed at all1 times as growth occurs, the City developed a Growth Management Plan wl- was ratified by the City voters in November 1986. The Growth Management Plan establis performance standards for eleven public facilities (city administration, library, wastewater treatmt parks, drainage, circulation, fire, open space, schools, sewer collection, and water distributic Performance standards must be met for these facilities before development can occur in an area. The Growth Management Plan is implemented by the Citywide Facilities and Improvements Plan, LC Facilities Management Plan, and individual project compliance. The Citywide Facilities Improvements Plan estimates the number of dwelling units that could occur at buildout of the City these estimates are the basis of the City’s Capital Improvement Plan, Growth Management Plan, public facilities plans. To ensure adequate provision of public facilities and services, the estim2 dwelling units cannot be exceeded. The maximum number of dwelling units which may be construc or approved after INovember 1986 is 5,844 in the Northwest Quadrant, 6,166 in the North1 Quadrant, 10,667 in the Southeast Quadrant, and 10,801 in the Southwest Quadrant. The limitati on new dwelling units were ratified by City voters in November 1986. The Land Use Element of the updated General Plan incorporates the limitations on new dwelling u established by the Citywide Facilities and Improvements Plan. The number of new dwelling u allowed by the Land Use Element is somewhat less than the maximum number of units allowed by Growth Management Plan due to recognized environmental constraints. As a result, implementa of the existing faciRities master plans will provide sufficient levels of public facilities and service ensure the quality of life for Carlsbad residents.

The purpose of the California Coastal Act is to protect the natural and scenic qualities of the California Coastal Zone by implementing long-range plans. The Coastal Act requires that individual jurisdictions adopt Local Coastal Programs (LCPs) to implement the Coastal Act at the local level. The City's Coastal Zone is divided into six segments and each segment is regulated by separate LCPs (Map 3.5-2: Local Coastal Program Boundaries). Almost all development within the Coastal Zone requires a Coastal Development Permit (CDP) in addition to other pertinent permits or entitlements. Coastal Development Permits are issued by the Coastal Commission unless the local jurisdiction has prepared an LCP that has been certified by the Coastal Commission and has been given authority to issue CDPs. Although the City has adopted LCPs for all of its segments of the Coastal Zone, only the LCP for the Village Redevelopment Segment has been certified by the Coastal Commission and the City can issue CDPs therein. The City is actively pursuing certification of the LCPs prepared for the other segments to gain the authority to issue CDPs throughout its Coastal Zone. The planned land uses established in the Land Use Element reflect the land uses established in the LCPs for the six segments of the Coastal Zone.

Elevations range from sea level along the coast to approximately 960 feet (280 rr the highest point along the southeastern boundary of the City. Major transportation routes serving the City of Carlsbad include Interstate 5 and State Route Carlsbad Boulevard which travels northhouth along the Pacific coast; Rancho Santa Fe Road wl traverses north/south along the eastern boundary of the City; El Camino Real which travels northkc through the center of the City; and Palomar Airport Road which traverses east/west through the ce of the City. The coastal portion of the City is characterized by cobblestone and sand beaches adjacent to sl coastal bluffs, as well as one freshwater lagoon (Buena Vista) and two saltwater lagoons (A Hedionda and Batiquitos). Buena Vista, at the northern border of the City, is fed by Buena Vista Crl a local drainage that forms much of the border between the cities of Oceanside and Carlsbad. watershed of Aqua Hedionda Lagoon includes a drainage that extends from Lake Calavera in northeastern corner of Carlsbad. Batiquitos Lagoon lies along the southern boundary of the City extends inland from the coast to near El Camino Real, where it receives runoff from slopes on the nl side of the lagoon and a drainage from the south. The lagoons provide habitat for a variety of resic and migratory bird species. The coastal bluffs of the City rise to a level marine terrace that stretches inland to gently rolling t East of Interstate 5 the topography of the City is characterized by rolling foothills containing area coastal sage scrub, chaparral, and grassland habitats. The hills are dissected by intermittent strc valleys containing riparian scrub, sycamore, eucalyptus, and oak woodland habitat, and three coi lagoon systems. The lagoons all contain extensive areas of wetland habitat, including saltwater freshwater marshes. The open space areas of the City support a variety of sensitive plant and an species. Over 300 species of plants, 200 species of birds, 25 species of reptiles and amphibians species of mammalls, 44 species of fish, 45 species of butterflies, and several thousand specie terrestrial and aquatic invertebrates retain populations within the City. Urban development has resu in degradation and loss of significant tracts of native habitats. Native communities associated \ this coastal area have been disrupted by agriculture, and abuses of active recreation and off-I vehicle use. In addition, encampments of migrant workers and homeless people have degraded na habitat, particularly in the riparian areas. The City has been a valuable agricultural area for many years, and has experienced significant UI growth over the past 40 years. Carlsbad has a combination of industrial, commercial and resider development, inclulding a redevelopment area, a large regional shopping center (1 million-plus sq. an internationally rioted resort (La Costa), an auto-retail center (with over 20 dealerships), a Ii industrial park areal (2,00O+-acre industrial corridor with over 4 million sq. ft. of light and ger industrial uses), and a general aviation airport. The older part of the City, referred to as the Vi11 is located in the northwest corner of the City. As of 1992, the assessed valuation of the City $6.4 billion. The City contains extensive agricultural areas and large tracts of undeveloped land. of 1992, a little over half of the City had been developed and a remaining quarter of the City w; various stages of development planning.

By t Miocene epoch, Southern California began to emerge as a series of mountains and valleys. Grani and metavolcanic rock were exposed to the east and rapidly thickening sections of Tertiary-aged stri were being upturned, compressed and folded. By about the Pleistocene epoch, numerous underwa terraces had been cut into the sedimentary rocks along Carlsbad’s coastline. The lowering of sea le caused erosion of the hills in the eastern highlands and the coastal plain, resulting in the curn topography. This origoing erosional process has created the alluvial and colluvial deposits which , found in the valley and canyon bottoms of Carlsbad (W-4). Topography The City can be divided into three distinct topographic areas: the beach, terrace, and rolling hills. 7 beach comprises less than one percent of the City, the terrace about thirty percent of the City, i approximately seventy percent of the City consists of rolling hills. The beach is very narrow wit1 width generally not exceeding 500 feet. Approximately a third of the coastal boundary, frc Batiquitos Lagoon to Palomar Airport Road, is sea cliffs which range from forty to sixty feet high. 7 terrace gently and uiniformly declines in a westerly direction. The maximum elevation ranges frc about 40 feet in the west, to about 1000 feet in the east. The terrace is cut by the channels of fl west-draining streams, three of which empty into lagoons - Batiquitos Lagoon, Agua Hedionda Lagoc and Buena Vista Lagoon. A fifth west-draining stream does not cut the terrace, but empties into c of the lagoons. In the area of rolling hills, elevations range from about 100 feet to about 1,000 fe but eighty percent of the area is less than 500 feet in elevation (R-1). Areas of steep slopes depicted on Map 5.1-1 : Carlsbad Slope Analysis. Soils The U.S. Soil Conservation Service (SCS) has divided the San Diego soil survey area into four mi physiographic provinces: the coastal plains, the foothills, the mountains and the desert. 1 designations reflect differences in climate, soils, topography, and land use. The City of Carlsbac located within the Coastal Plains and Foothills provinces (R-2). The San Diego soil survey area has been divided into approximately 70 soil series assigned to eight ! groups. The soil ancl associations groups reflect a landscape that has a distinctive pattern of soils z is tied to the physiographic provinces (R-3).

FINAL MASTI Environmental impact Rem CITY OF CARLSBAD I I I I I 1 I I 1 1 1 I 1 I I Erodibility Erosion is a normal geologic process whereby earth materials are loosened, worn away, decompo: or dissolved, removed from one place and transported to another, sometimes many miles away fr their source. Precipitation, running water, waves, temperature, and winds are all agents of erosi Ordinarily, erosion proceeds so slowly that is imperceptible; but, when the natural equilibrium of environment is changed, the rate of erosion can be greatly accelerated. This can create aesthetic well as engineering problems, although not normally posing a threat to life or property. There are th main erosion problems within the City. They are: (1 ) accelerated erosion in soft rock soils; (2) siltat of the lagoons; and, (3) beach and sea cliff erosion. In Carlsbad, most of the soils have sev erodibility limitations;, with the exception of the Salinas - Corralulas, Diablo - Altamont and Diablo - Flores Associations whose limitations are low to moderate. I Landslides A landslide is the movement of earth materials down a hillside or steep slope area. Landslide probk usually occur when a hillside is oversteepened, the support at the base is moved, additional mate or fill is loaded onto the hillside, or water saturates into the slide mass. Landslide problems are rn prone to occur when the slope contains out-of-slope bedding or planner bedrock units that are dipp or inclined out-of-slope. Recognition of areas susceptible to large scale movement, and appropri planning and design can greatly reduce the possibility of damage to property and risk of life. Carlsbad, landslide areas are mainly found on the north-facing slopes along creek channels. A 1 landslide areas occur in granitic and metavolcanic rocks where weathering has created deep soils (R Seismic Characteristics 1 Backaround Southern California has, and will continue to be significantly impacted by damaging earthquak Several faults within Southern California have the potential to generate earthquakes that will ca strong ground motions.

FINAL MASTER Environmental JmRact ReRort Seismic effects are classified as primary and secondary. The primary effect is ground rupture, also called surface faulting and ground motion. Secondary effects are the results of ground motion during an earthquake. Those relevant in the City of Carlsbad are liquefaction, lurch cracking, lateral spreading, local subsidence, landslides, structural damage due to ground vibration, seiche, tsunami, and regional subsidence and uplift. Primary Effects Primary effects are caused by movement along an active fault. These movements can be sudden and severe as in an earthquake, or slow and imperceptible as in fault creep. Movement on a fault can be horizontal, vertical, or a combination of both. The closest known active fault, as indicated on Map 5.1 - 3, is the Rose Canyon Fault Zone located two to three miles offshore to the west of Carlsbad. Geologists have estimated that the maximum earthquake magnitude that is likely to occur in a 1 OO-year period on the Rose Canyon Fault is 6.9 on the Richter scale. This size earthquake is considered a moderate earthquake. Using the Richter magnitude, the distance from the fault and other factors, bedrock acceleration values can be determined for seismic design of structures. A seismic ground shaking map representing the most likely significant ground shaking values within the City vs prepared as shown on Map 5.1-5: Seismically Induced Ground Shaking Map (R-3). Ground rupture is not considered a hazard in Carlsbad. Secondary Effects Secondary effects pertinent to the study area are liquefaction, lurch cracking, lateral spreading, local subsidence of soils, landslides, vibrational damage, seiche, tsunami and regional subsidence and uplift. The following is a discussion of the potentials for secondary effects likely to occur during an earthquake in the City of Carlsbad (R-1 1. Tsunamis and Seiche A tsunami is a sea wave generated by a submarine earthquake, landslide or volcanic eruption. A seiche is a series of wave oscillations in a body of water and can be compared to the waves generated in a pan of water when it is rocked. Although tsunamis have been recorded along the southern California coastline, they occurred within the normal tidal range and were probably not noticed by the casual observer. Seiches could occur in the Carlsbad lagoons, although they probably would not affect areas 5 to 10 feet above the water level (R-3). Liquefaction Soil liquefaction is defined as the transformation of a granular material from a solid into a liquefied state as a consequence of increased pore-water pressures. It is caused by seismic vibration of fine sand or silt which is saturated with water. There are limited areas in the City which are considered potentially subject to liquefaction (R-1). They are the alluvial areas west of El Camino Real, the areas in and around the lagoons, and the areas along the beaches.

The alluvial areas west of El Camino Real, the areas in and around the lagoons, and the areas along the beaches are considered potentially subject to lurch cracking (R-1). Lateraf Spreading Lateral spreading is the movement of loose soils over low-angle slopes into open areas during an earthquake. The alluvial areas west of El Camino Real, the areas in and around the lagoons, and the areas along the beaches are subject to lateral spreading (R-I 1. Local Subsidence Local subsidence can occur during an earthquake when water is driven out of saturated soils causing them to become more compact. The alluvial areas west of El Camino Real, the areas in and around the lagoons, and the areas along the beaches are considered potentially subject to subsidence (R-1). Landslides Landslides can result from ground shaking during an earthquake. Failures are common in old landslides and oversteepened slopes such as roadcuts, building sites, seacliffs and stream-cut canyons. Landslides are mainly found along north-facing slopes along creek channels and in granite and metavolcanic rocks where weathering has created deep soils. With the technology available today, most landslides can be mitigated to the point where the chances of failure are very small (R-3). S truc tura f Damage Structural damage due to ground vibration is caused by the transmission of earthquake vibrations from the ground into the structures. The variables which determine the extent of damage are (1) the characteristics of the underlying soils and/or rocks; (2) the design of the structure; (3) the quality of materials and workmanship used in construction; (4) the location of the epicenter and magnitude of the earthquake; and, (5) the duration and intensity of ground shaking. The potential for structural damage due to ground vibration in the City of Carlsbad is greatest in areas underlain by deep, soft, saturated alluvial soils and least in areas ob hard bedrock (R-1). Regional Subsidence and Uplift Regional subsidence and uplift during an earthquake are caused by differential vertical movement along an active fault. This occurs over large areas, and the amount of subsidence or uplift is usually on the order of a few inches to a few feet. It is generally not possible to assess the hazard to individual locations; however, the City can be expected to respond as a unit. Therefore, this phenomenon is not considered to be a hazard in the City of Carlsbad (R-1). 5.1.2 Basis for Determininq Siqnificance The project will have potentially significant impacts if it will: 1.

Property damage, personal injury, and I of life may result from earthquake events. Because implementation of the updated General Plan result in more people residing in Carlsbad, more people and property will be exposed to the poten seismic hazards. Seismically induced liquefaction, lurch cracking, lateral spreading, local subside1 and landslides have a potential to occur within limited areas of the City (R-I). Proper construct according to the City's Grading Ordinance, Hillside Development Ordinance, and building codes substantially reduce structural damage and injury from ground shaking. Steep Slopes Steep slopes present a constraint to development throughout the City. According to the General PI areas of the City with slopes in excess of 40 percent are considered undevelopable, and areas slopes between 25 and 40 percent are limited to 50 percent of the density otherwise permitted on property. Lower derisity development in areas with steep slopes will reduce hazards caused by builc in such areas. Any development in steep slope areas must undergo the Hillside Development Per review and approval process which requires remedial measures to be taken by the applicant to mitig hazards presented by the steep slopes. Landslides Landslides could be a destructive geotechnical hazard in Carlsbad. Small-scale slides and slougt can be seen in most road cuts including those of improved roads in the eastern portion of the Ci Landslides are mainly found along north-facing slopes along creek channels. A few landslide areas in granite and metavolcanic rocks where weathering has created deep soils (R-I 1. Recognition of ar susceptible to large scale movement, coupled with appropriate planning and design, can greatly red the possibility of damage to property and risk of life due to landslides. Soils Further development of the City may be constrained by soils with high clay content. The clay lai have a moderate to high shrink-swell potential and may present constraints to underground utility lir Structural foundations can be protected from subsurface shrink-swell behavior by remedial grac techniques. Approximately 40 percent of the City is currently undeveloped. Given the general types of the area and utilizing conventional engineering methods, proper design and construc procedures, the majority of this area will be developable. I I I SOILS and GEOLOGY 5.1-1 FINAL MASTER En vironmentai ImRact ReRort Erosion and Siltation Erosion and siltation are normal geologic processes occurring in the City of Carlsbad. Changes to the environment caused by implementation of the General Plan update may accelerate the rate of erosion and siltation. Engineering measures can be taken to alleviate and remedy the problems of erosion and siltation. Investigation and evaluation of individual affected areas associated with individual development projects are necessary to decide which measures are most appropriate in each situation. 5.1.4 Level of Sianificance The soils and geology impacts of implementing the updated General Plan will be significant, but can be mitigated to a level of less than significant. 5.1.5 Mitiaation Measures The following measures are required to mitigate significant impacts related to geology and soils. CITY OF CARLSBAD 1. Require project applicant to submit evidence that structures are designed to meet ground response characteristics of their individual site. (Public Safety Element, Geology and Seismic Safety, C.2.) Utilize the City's geotechnical maps as generalized guidelines for planning purposes and in determining the type of geotechnical report to be required as well as the extent of the report. (Public Safety Element, Geology and Seismic Safety, C.4.) Require applicants to conduct detailed geologic and seismic investigations at sites where the construction of critical structures and structures over four stories are under consideration. (Public Safety Element, Geology and Seismic Safety, C.5.) Require qualified professionals in the fields of Soil Engineering and Engineering Geology to review grading plans and inspect areas of excavation during and after grading, and to evaluate slope stability and other geotechnical conditions that may affect site development and public safety. It is imperative in areas of known or suspected landslides and/or adverse geologic conditions to ascertain slope stability before and after development. The following determinations should be made in these cases: extent of landslide, depth-to-slide plane, soil types and strengths, presence of clay seams and ground water conditions. (Public Safety Element, Geology and Seismic Safety, C.7.) Abate or modify potentially hazardous structures when loss of life is a potential factor. If the demolition of residential structures is required, an adequate relocation program for the residents of the structure shall be instituted. (Public Safety Element, Geology and Seismic Safety, C.10.) Require the installation of appropriate siltation and erosion control measures on proposed building and development sites wherever there is a potential for soil erosion.

Discussion and analysis focuses on natural water system conditions in City. Reclaimed water facilities and potable water supplies are discussed in Section 5.1 2, Utilities Public Services. 5.2.1 - Environmental Settinq Because Carlsbad varies widely in topography, a variety of drainage conditions also exist within City boundaries. Carlsbad is divided into four major waterways, three of which empty into lagol Alluvial material within a system of perennial and intermittent streams have created valleys and SI canyons to the east. In the lower basins, these streams begin to widen into flood plains suppoi dense willows and other riparian habitats. With the exception of Encinas Canyon, each of tt drainage basins further expands into a lagoon supporting a variety of flora and fauna. The four distinct watersheds or drainage basins in Carlsbad, as illustrated on Map 5.2-1: Carl: Drainage Basin Map, are Buena Vista Creek, Agua Hedionda Creek, Encinas Creek, and Batiqi Lagoon Watershed. Listed below is a description of each watershed basin. Buena Vista Creek Buena Vista Creek drains an area of nineteen square miles. The drainage area is long and narron extends from the San Marcos Mountains at 1,671 feet above sea level to the Pacific Ocean nine n downstream. Runoff from several tributaries quickly combine into one main improved channel wi the City of Vista. Flow is generally in a southwest direction through the City of Vista. As it le: the City of Vista, flow becomes more westward and enters Buena Vista Lagoon approximately miles east of the ocean (R-4). Stream flow eventually enters the Pacific Ocean after being tempor delayed by the colnsiderable storage volume of the lagoon. A weir structure at the ocean 01 controls discharge (R-6). The stream gradients run from 68 feet per mile in the upper reaches tc feet per mile in the lower reaches of the basin. The average gradient within the reach studied i! feet per mile. Agua Hedionda Creek Agua Hedionda Creek and a major tributary, Buena Creek, drain an area of twenty-nine square mi Agua Hedionda Creek originates in the hills south of San Marcos Mountains, flows in a gen southwest direction, and confluences with Buena Creek about three miles downstream. Buena Crc with a drainage area of about six square miles, originates in the San Marcos Mountains and flc about five miles in a southerly direction before it confluences with Agua Hedionda Creek. The strt gradient of Buena Creek through the study reach is about 51 feet per mile. From the confluence \ Buena Creek, Agua Hedionda Creek flows generally westward about six miles and enters A Hedionda Lagoon. It then discharges into the Pacific Ocean two miles further downstream. The stream gradients along Agua Hedionda Creek range from about 43 feet per mile in the ul reaches of the study area to about 35 feet per mile in the lower reaches approaching the laga There is an extremely steep canyon reach between mile 5.2 and mile 6.0 along Agua Hedionda Cr which is called Los Monos Canyon. Stream gradients in this reach average 180 feet per mile. 1 HYDROLOGY 5.2.

This basin originates 3,000 feet east of El Car Real within the City and drains westerly approximately 22,000 feet to the Pacific Ocean. The drair course generally parallels Palomar Airport Road along an alignment just south of this roadway. entire drainage area ranges in elevation from sea level to slightly over 440 feet above sea level. Batiquitos Lagoon Watershed The Batiquitos Lagoon Watershed is divided into two major drainage basins known as the San Mal Creek watershed and the Encinitas Creek watershed. San Marcos Creek originates in the San Mal Mountains and empties into Batiquitos Lagoon about 2.6 miles east of the Pacific Ocean. Encin Creek, a major tributary, originates in the mountains southwest of San Marcos and joins San Mal Creek at the upstream end of Batiquitos Lagoon. The entire drainage area totals 46 square miles ranges in elevation from sea level to slightly over 1700 feet in the Merriam Mountain range. The stream gradient ranges from an average of ten feet per mile just before reaching the shorelin about 600 feet per mile in headwaters. San Marcos Creek has a small and indistinct channel upstr from Lake San Marcos. Below that point, the channel is well-defined, steep, and rocky througl Costa after which it becomes small and not well defined again to Batiquitos Lagoon. The flood p is broad upstream again from Lake San Marcos. From Lake San Marcos Dam to the La Cc Development, there is virtually no flood plain due to the steep well-defined channel. Through tht Costa development to the Batiquitos Lagoon, the flood plain is again broad. During large floods, flc exceed the channel capacity and inundate parts of the broad flood plain. Batiquitos Lagoon exte from the downstream limit of San Marcos Creek, namely the Pacific Ocean, as far as El Camino R some 2.6 miles upstream. It comprises about 600 acres of area and would provide consider; storage during large floods (R-4). Groundwater The City is not located in a groundwater basin. However, groundwater basins do occur througt the county as illustrated on Map 5.2-2: Groundwater Basins (R-2). Many of these groundwater ba play an important role in meeting local water demands. Over 90 percent of natural local supplie Southern California are produced from groundwater basins. These basins are supplied naturally precipitation and stream runoff percolating into the soil. Recharge of groundwater occurs from hur intervention as well. When groundwater is low, some basins are recharged by imported water tc stored for future use. When supplies are short, the groundwater can be pumped back into surf reservoirs. Although Carlsbad has little potential for obtaining groundwater supplies, the Carlsbad Municipal Wi District maintains riights to the San Luis Rey (Mission) River Basin in Oceanside. Studies will nee( be completed in order to determine the water qualiuy of the basin and the feasibility of provic groundwater from the basin to Carlsbad (R-3) for domestic use. 1 B HYDROLOGY 5.2.

Forty to eighty percen pollutants currently found in surface waters are a result of urban runoff. The different pollut< reaching the City's water bodies have varying affects. Increased nutrient loads cause algal blo which decrease amounts of dissolved oxygen. Concentrations of metals, such as cadmium, cop and lead, often find their way into the food chain and impose detrimental health effects to wildlife 4). Another source of pollution in Carlsbad comes from accidental sewage spills, which often re in bacteria levels temporarily exceeding safe health standards along the shoreline. Such sl: however, are discovered early due to routine inspections and corrected immediately. The spills re in only short term environmental effects and rapidly dissipate to acceptable safety levels after reacl the ocean. Currently, pollutants discharged through storm water are largely uncontrolled in the C Implementation of the City's 1993 Storm Water Quality Management Plan, which has not yet b administered, will eliminate and/or reduce storm water pollutants from entering the City's sur waters. Today, only "point" source discharges, such as industrial outfall pipes, are adequa regulated. Illegal sewage connections, waste dumpings, and "non-point" source pollutants ( fertilizers, pesticides, grease, oils, automotive and power plant soot, trash, human and an excrement) are not adequately regulated, and therefore, are suspect to degrading the water qualitl all three lagoons. The lagoons are in violation of the water quality objectives of the Water Quality of 1987. Soil erosion and sedimentation caused by construction activities and increased surface rui have also degraded the quality of the City's drainage basins. Because of manmade weirs, Batiqu and Buena Vista Lagoon are isolated from the continuous flushing of the tides (R-5,61. These lago are collecting ponds for upstream sedimentation and pollutants. Flood Plains Flooding primarily occurs during the winter when heavy rains are more frequent and ocean waves highest. According to the 1987 National Flood Insurance Program Maps, 1 OO-year flood plains found primarily along the ocean shoreline and the creek channels and lagoons of each of the . drainage basins. The one percent annual chance (1 OO-year) flood has been adopted by the Fed. Emergency Management Agency as the base flood for flood plain management purposes. Land u in flood plains are managed and regulated under Chapter 21,110 of the City's Zoning Ordinance v the intent to minimize the effects flood hazards impose on the public health, safety, and genl welfare. The National Flood Insurance Program Maps are available at the City of Carlsbad Planr Department.

A majority of the non-residential buildings will occur in the center of the city surrounding ' I McClellan-Palomar Airport. As development occurs in the City, impervious surfaces will increase from the placement of ro( parking lots and builldings. These facilities will reduce xhe amount of water absorption into the grot and will increase direct runoff into the City's creeks and lagoons. This runoff will contain additic pesticides, oil, grease, and other toxic substances and the water quality of surface water wil degraded. The surface waters receive the highest concentrations of pollutants during heavy rainfalls proceel long periods of drought. Because heavy rainfall is infrequent, however, urban runoff does not pre. an ongoing source of non-point pollution along Carlsbad's shoreline. The ocean receives th pollutants by either direct runoff or streamllagoon outlets. The ocean also receives 12 million gall per day of treated effluent from the City of Oceanside and 20 million gallons per day from the Enc Wastewater Treatment Plant. The wastewater from both plants receive secondary treatment and diluted to safe environmental levels (R-8). All four drainage basins will be impacted by the updated General Plan land uses. Buena Vista Cr will continue to receive pollutants from existing high density commercial development. Future I uses abutting the basin include Open Space and Residential Low-Medium. Future development probably add additional pollutants and sediments into the lagoon. Future development within the Agua Hedionda Creek basin will lie primarily within low to medii density residential land use areas. Such land uses could have significant impacts once developed. tidal flushing of the lagoon should help eliminate an excessive accumulation of pollutants. The Encinas Creek basin could also be impacted by non-point source pollutants from fu development. Future development includes Planned Industrial north of the creek and low to medi density residential !south of the creek. Batiquitos Lagoon Watershed consists primarily of low to medium density residential intermixed I open space and commercial land uses. Much of this land is still undeveloped and impacts f development of this land are expected. The lagoon has been subject to an accumulation of sedimei nutrients, and other constituents due to its isolation from tidal influences. The lagoon's condii should improve, however, once it is opened to tidal influences as part of the Batiquitos Lag1 Enhancement Plan. Dredging is expected to begin in 1994. During grading and construction, potential for sedimentation in the creeks and lagoons increases to the removal of vegetation and altering of natural topography. Once development of the prop1 is complete and landscaping is installed, onsite erosion and sedimentation will typically decrease increased runoff due to impervious surfaces results in the potential for downstream erosion.

Although significant changes are unlikely, existing development that was once outside the floodplain, as well as undeveloped land, could be affected. Minimal impacts from flooding are anticipated, however, because much of the floodplains in Carlsbad are designated as Open Space and little development is located or permitted within the City's floodplains. Installation of future drainage facilities is assured because such facilities will be installed concurrent with development as required by the City's Growth Management Program. There are, however, drainage deficiencies associated with existing development, especially in the downtown area. The cost to mitigate existing deficient facilities will be paid through a combination of drainage area fees charged to redevelopment and remodel projects, previously collected drainage fee revenues, and other City funding sources (R-4). 5.2.4 Level of Sisnificance Implementation of the General Plan will result in significant impacts to hydrological resources.

Frequent high pressure over the Pacific deflects most st systems to the north, resulting in dry and warm summers and mild, occasionally wet winters in IT of coastal Southerri California. Temperatures along coastal San Diego County average from the 50's during the winter to the low 70's in the summer. Almost all rainfall occurs between October April, averaging about 10 inches annually. The average annual humidity is about 70 percent and tt are approximately 1148 days with clear skies each year. The coastal areas experience daily shifts in the wind direction due to the different heating rates of land and ocean. T'he winds blow offshore at night and in the mornings, and shift onshore in afternoon. This local wind pattern is sometimes interrupted by the regional wind pattern known as "Santa Ana" winds, which brings clear skies and strong, hot, and dry winds from the east. Air temperature normally decreases with increasing elevation, which allows hot air to rise. Coal southern California experiences temperature inversion layers where the air temperature increases v elevation. These inversion layers trap pollutants by preventing vertical dispersion. During th conditions, pollutedl air can only be dispersed by lateral winds. When these winds blow offshore, during Santa Ana clonditions, the skies are clear and clean throughout southern California. When Santa Ana winds subside, the pollutants that were blown offshore from the Los Angeles area blown onshore into San Diego County. This results in the highest levels of air pollutants in the ai Despite the influx of pollutants for the Los Angeles area, much of the air pollution over Carlsbad I the surrounding Saln Diego region is produced within the San Diego region. In order to monitor control this pollution, the region has been defined as a separate "basin of air", known as the San Dil Air Basin. Air Quality Standards Ambient air quality is a measure of the purity of the air. Air quality is diminished by the release pollutants into the ,air from local and nearby sources. Air quality is enhanced by dispersion of thc pollutants through winds and rising air. The principle pollutants of concern in coastal south California are photochemical hydrocarbons (smog), carbon monoxide, nitrogen dioxide, sulfur dioxi and suspended inhaleable particulates. Smog is measured and expressed as ozone and is the primary air quality concern in the coastal are The principal source! of smog comes from the reactive organic gases that are emitted by mobile sour1 (cars, trucks, and buses). These gases react with sunlight to form smog. Carbon monoxide, nitro( dioxide, and sulfur dioxide levels are low in the coastal, suburban areas since they are mostly produc by severe traffic corigestion and sulfur-burning electric power generators. Suspended particulates hG not been monitoreal as effectively as the other pollutants and the size of particulates measured c vary. The major source of particulates are motor vehicles, however industrial activity, agricultu grading activities, and suspended sea salt also contribute to airborne particulate levels. FINAL MASTER Environmental Impact ReRort Regulatory Framework Since the Federal Clean Air Act of 1970, a series of federal and state legislation has been enacted to enhance the quality of air. As a result of this legislation, federal and state pollutant concentration standards have been derived. These standards are designed to protect those people most susceptible to respiratory stress, known as sensitive receptors. Also as a result of the legislation, air quality management districts have been established to measure pollutant concentrations in their air basin and monitor their conformance with federal and state standards. If an air basin does not meet the air quality standards, the responsible air quality district must prepare an air quality plan to show how the standards will be attained. The San Diego Air Basin is classified as a "severe" non-attainment area for both federal and state standards for ozone (smog). The San Diego Air Basin also exceeds the state standard for airborne particulate matter. Management of the air quality in the San Diego Air Basin is under the authority of the San Diego Air Pollution Control District (APCD). The APCD has prepared a 1992 revision to the Regional Air Quality Strategy (RAQS) to comply with state and federal legislation and to attempt to address attainment of both state and federal standards. The California Clean Air Act of 1988 requires that emissions be reduced by five percent each year from the base year of 1987. If the five percent requirement cannot be met, the air quality management district must implement all feasible measures to improve air quality on a practical schedule. The RAQS must be revised every three years to reflect changes in regional growth patterns, or federal mandates. Some components of the Regional Air Quality Strategy are: 1 ) increasing the use of clean fuel motor vehicles in fleets; 2) specific control measures for stationary sources of air pollution (such as electric power generation) and areawide sources (such as barbecue lighter fluid); and 3) transportation control measures (such as trip reduction programs and transportation system management). Monitored Air Quality Ambient air quality is recorded by the APCD at several air monitoring stations within the San Diego Air Basin. The closest monitoring station to the City of Carlsbad is the Oceanside station, located on the coast five miles north of the City. Table 5.3-1 : Number of Days Federal and State Emission Standards Exceeded at Oceanside Monitoring Station, shows the number of days that federal and state emission standards were exceeded annually at the Oceanside station between 1987 and 1991. Ozone levels have exceeded both the federal and state standards and suspended particulates 10 microns or smaller in size (PM-10) levels have exceeded the state standards. Health Effects While healthy people can occasionally tolerate poor air quality, polluted air can have severe effects on people susceptible to respiratory distress. These sensitive receptors include people suffering from asthma or other respiratory conditions, the very young and elderly, and people engaged in heavy labor or exercise. Table 5.3-2: Air Pollution Effects, summarizes the health problems and other ill effects that result from air pollution. Since the state and federal air quality standards are based upon air pollution tolerance of sensitive receptors, health impacts of air pollution can be evaluated by tabulating the number of days that the standards were exceeded.

Cause any Federal, State, or local ambient air quality standard to be exceeded, Contribute substantially to an existing or projected air quality violation, Expose sensitive receptors to substantial pollution concentrations, Conflict with the County of San Diego Air Pollution Control District Regional Air Quality strategies (RAQS), or 5. Create objectionable odors. 5.3.3 Environmental lmoact Since the San Diego Air Basin is a "non-attainment basin", any additional air emissions could be considered significant; therefore, continued development to buildout as proposed in the updated General Plan will have impacts on the air quality of the region. To calculate these impacts, the energy consumption and vehicle miles traveled for 1990 and buildout conditions are compared. The only pollution sources evaluated are those that are subject to change due to development under the General Plan. Point sources such as the SDG&E Encina power plant and the Encina Wastewater Treatment facility have not been considered because their emissions are under control of the Air Pollution Control District and not under the purview of this General Plan. Table 5.3-3: 1990 Energy Consumption and Table 5.3-4: 201 0 Buildout Energy Consumption, show the estimated energy consumption and vehicle miles traveled under the 1990 and buildout conditions. Buildout of the updated General Plan is assumed to occur by 201 0. The total dwelling units and square footage of non-residential uses is derived from data monitored through the City's Growth Management Program. The buildout estimates approximate the maximum potential development to evaluate a worst-case scenario for environmental impacts. Commercial uses are grouped by their respective traffic generation rates. The traffic generation rates are calculated by calibrating those used by San Diego Association of Governments (SANDAG) with existing traffic counts. The energy usage factors are taken from the South Coast Air Quality Management District. Table 5.3-5: Difference in Emissions from Existing to Buildout, shows the net changes in total emissions for the five principle air pollutants from 1990 to buildout conditions. The emissions due to mobile sources are based upon the California Composite Moving Exhaust Emission Rates, derived by the California Air Resources Board. The emissions due to energy consumption are from the South Coast Air Quality Management District. One of the assumptions of the estimated emissions is the improvement in automobile efficiency between now and the year 201 0, thereby lessening the amount of air pollution emitted into the air. Despite improved automobile efficiency, buildout of the updated General Pian will increase sulfur oxides by 71.9 percent, nitrogen oxides by 17.3 percent, and suspended particulates by 43.8 percent. Reactive organic gas emissions and carbon monoxide emissions will decrease by 42.4 and 13.7 percent, respectively, due to increased automobile efficiency. As traffic volumes increase, the opportunities for congested intersections also increases. A large volume of traffic idling at a congested intersection causes a "hot spot" of carbon monoxide emissions. These "hot spots" are significant sources of carbon monoxide in the congested areas of San Diego and 5.3-4 AIR QUALITY i I I I 8 I I I I 1990 ENERGY CONSUMPTION Natural Gas Electric Power Vehicle Miles Traveled Land Use Units Usage Daily Usage Daily Usage Daily Use Mi.

This document has been included as Appendix D. General Topography and Landscape Features The City of Carlsbad is situated along the Pacific Coast of California, in northwestern San Di County. The City occupies approximately 42 square miles. Elevations range from sea level along coast to about 1,000 feet at the southeastern border of the City. The western edge of the cil characterized by sandy beaches and three low-lying river estuaries or lagoons - Batiquitos Lag( Agua Hedionda Lagoon, and Buena Vista Lagoon. The lagoons dominate the coastal landscapc Carlsbad and provide habitat for a variety of resident and migratory bird species. With the excep of some habitat that immediately borders the estuaries, native communities on the immediate CI either have been degraded severely by human activities or completely eliminated by developm Inland from the coast is a series of low coastal mesas and rolling foothills, which support shrublai grasslands, and agriculture. Intervening ravines and canyons support narrow oak woodland, ripa scrub, coastal sage scrub, and chaparral communities. Two large freshwater bodies occur wi Carlsbad near the eastern edge of the city - Lake Calavera and Squires Dam. Both support adjac freshwater marsh and riparian woodlands. Geoloav and Soils_ The City of Carlsbad lies entirely within the Coastal Geomorphic Province, which occupies the wes portion of San Diego County corresponding to the region of sedimentary surface rocks. The domir relief of this provinlce is a series of marine terraces also known as mesas. Approximately 25 diffei soil series are present in the City of Carlsbad, including sandy, cobbly, loamy, and clayey types, soils associated with gabbro parent material and Santiago Peak metavolcanic formations. On coastal terraces most of the soil series are comprised of sandy loams, clay loams, and clays. In foothills the soils generally are well-drained sandy loams or silt loams overlaying decomposed grai or metavolcanic rock. Plant Communities Eight distinct native plant communities are present within the City of Carlsbad. In addition, there three non-native habitat types. Open water and urbanized areas also account for significant ai within Carlsbad. These native and non-native habitat types include coastal sage scrub, chapa grassland, southern coastal saltwater marsh, coastal and valley freshwater marsh, sycamore alii woodland, riparian scrub, oak woodland, disturbed wetland/flooding, eucalyptus woodland, distul habitat, developed, and open water. A detailed description of each type of habitat is includec Appendix D. Map 5.4-1: Carlsbad Vegetation Map, shows the generalized location of these p communities. Presented in Table 5.4-1: Acres by Aggregated Vegetation Types within the City of Carlsbad, acreages of habitat type for the City. More than 10,000 acres (40.9 percent) of the City of Carls are developed. Approximately 10,200 acres (41 percent) of the City still support natural habitat. the natural habitat, approximately 7,150 acres (70 percent) are comprised of native habitats.

Each of these species are discussed in detail in Appendix D . Table 5.4-2: Sensitive, Rare, Threatened or Endangered Plant and Wildlife Species, depicts the current status of these species, and Map 5.4-2: Carlsbad Sensitive Species Map, shows the recorded location of observed sensitive species. Sensitive Wildlife SDecies Birds Several species of birds recognized as threatened or endangered by state or federal agencies occur within Carlsbad as overwintering individuals or resident populations. These include the light-footed clapper rail, Belding's Savannah sparrow, and California least tern, all associated with coastal estuaries and salt marsh habitats. The least Bell's vireo, restricted to riparian woodlands, and the California gnatcatcher, occurring primarily in coastal sage scrub communities below about 1,200 feet (370 m), also exist in Carlsbad. The latter species is fairly widespread in coastal sage scrub habitats throughout Carlsbad (R-1 1. The California gnatcatcher is the most widespread sensitive wildlife species present in the City. Other recognized sensitive bird species that occur in Carlsbad include the coastal cactus wren, sage sparrow, and several species of raptors. See Map 5.4-2 for the distribution of these species. Reptiles and Amphibians Sensitive reptiles documented in Carlsbad include San Diego horned lizard, orange-throated whiptail lizard, western whiptail, and northern red diamond rattlesnake. Other sensitive reptiles likely to be present include two-striped garter snake and southwestern pond turtle. The western spade-foot toad has also been observed in the City. These species are recognized as federal Category 2 candidates for listing as threatened or endangered by the USFWS or as "Species of Special Concern" by CDFG Mammals No mammal species recognized as threatened or endangered by the USFWS or CDFG have been observed in the City. However, three federal Category 2 candidate species are highly likely to occur in Carlsbad: the San Diego black-tailed jackrabbit, San Diego desert woodrat, and northwestern San Diego pocket mouse. Category 2 species are candidates for federal listing where existing biological information indicates that listing may be warranted but substantial biological information to support a proposal to list as threatened or endangered is lacking. Four other mammal species recognized as federal Category 2 candidates for listing as threatened or endangered have a remote chance of occurring at least occasionally in Carlsbad. These include the Pacific pocket mouse, Townsend's western big-eared bat (Plecutus tuwnsendi/l, California mastiff bat (Eumups perutis califurnicus), and spotted bat (Euderma maculatum). The Pacific pocket mouse has been recorded near the coast in the City of Oceanside but otherwise is extremely rare within its historic range (Ft-1). None of the bat species have been recorded in Carlsbad, and there are relatively few suitable roosting sites for bats within the city limits. The California mastiff bat, which has been recorded near Lake Hodges, and the spotted bat both require rugged, rocky areas with crevices for roosting.

In vertebrates Four species of butterflies that are resident or potentially resident within the City of Carlsbad recognized as federal Category 2 candidates for listing as threatened and endangered: Harbison's I skipper, salt marsh skipper, Hermes copper, and quino checkerspot. Although only the salt m: skipper has been documented in Carlsbad, Harbison's dun skipper and Hermes copper are highly lil residents. Both are fairly host specific insects and usually are encountered wherever their la foodplants occur. The larvae of Harbison's dun skipper feeds exclusively on San Diego sedge (Ci spissa), which has lbeen observed from several oak woodland and riparian areas within the City. larvae of Hermes copper feed on redberry (Rhamnus crocea), which is a common species througt much of the chaparral in the City. In addition to these sensitive butterflies, the federal Categoi candidate globose dune beetle, a resident of coastal dunes, may be present in small remnants of du along the coastal margins of the City. Sensitive Plant Sr)ecies Within the City of Carlsbad, 19 species of plants recognized as regionally sensitive by the Califoi Native Plant Society (R-5) have been detected. These species include San Diego thorn-mint, Califoi adolphia, Del Mar rnanzanita, San Diego sagewort, thread-leaved brodiaea, Orcutt's brodiaea, w, stemmed ceanothu!;, summer-holly, Del Mar Mesa sand aster, western dichondra (western pony fo cliff spurge, chocolate lily or mission bells, Palmer's grappling hook, San Diego marsh-elder (pow weed), San Diego (;olden-star, spiny rush, Engelmann oak, ashy spike-moss or mesa clubmoss, l narrow-leaved nightshade. The most widespread sensitive plant species within the City include California adolphia and ashy sp moss, which primarily occur in coastal sage scrub; and wart-stemmed ceanothus, summer-holly, Del Mar manzanita, which primarily occur in southern maritime chaparral. In drainages and ripai areas spiny rush is fairly common. Other sensitive plants encountered less frequently include $ Diego golden-star, western dichondra, Engelmann oak, San Diego sagewort, San Diego marsh-elc San Diego thorn-mint, and thread-leaved brodiaea (R-1 1. Environmental Resource Protection Reaulatorv Control of Environmental Resources There are a variety of programs to protect environmental resources in the City of Carlsbad. Thl programs operate at all levels of government, including federal regulations such as the Endange Species Act and National Environmental Policy Act (NEPA), state regulations such as the Califoi Environmental QuaWity Act (CEQA), and City regulations such as the Carlsbad municipal code. - applicability of these regulations to the various types of sensitive plant and wildlife habitats in Carlsk is shown in Table 5.4-3. The shaded boxes indicate which regulations may play a role in preserv this habitat type. 'The agencies responsible for regulating environmental resources and issuing 1 required permits include the U.S. Army Corps of Engineers (ACOE), U.S. Environmental Protect Agency (EPA), U.S Fish and Wildlife Service (USFWS), California Department of Fish and Ga (CDFG), and Carlsbad Planning Department.

ODen SDace and Conservation Resource Management Plan The City of Carlsbad Open Space and Conservation Resource Management Plan (OSCRMP) defines priorities for open space planning on a citywide basis and for the City's 25 Local Facilities Management Zones (R-3). Priorities were established by considering the importance of each open space type and the degree of protection already afforded to that open space type by existing regulations. Citywide priorities were ranked from 1 (top) to 5 (lowest). Priorities for individual zones were ranked in terms of five categories of action: A (primary action), B (secondary action), C (already protected), D (low protected or not applicable), and E (administered through another program). Five primary categories of open space were considered: (1 1 open space for preservation of natural resources; (2) open space for managed production of resources; (3) open space for outdoor recreation; (4) open space for aesthetic, cultural, and educational purposes; and (5) open space for public health and safety purposes. With respect to citywide goals, the OSCRMP identifies open space for the preservation of plant, animal life, and habitat as a top priority. This designation expresses the City's general intent to optimize natural resource values throughout the open space system and to maximize the protection and enhancement of wildlife and habitats within various preserves. Green ways One of the primary priorities of the Open Space and Conservation Resource Management Plan is greenways. A greenway in Carlsbad may be defined as an open space connector linking nature preserves, cultural features, larger areas of open space, parks, and historic sites to each other, and with other areas of the City. The objective of the greenway system is to improve environmental quality and enhance the open space system in the City. Greenways in the City of Carlsbad will serve several functions including the wildlife corridors, buffers adjacent to habitat preserves; recreation areas, and viewsheds (R-3). 5.4-10 BIOLOGICAL RESOURCES FINAL MAS1 Environmental Impact Rei CITY OF CARLSBAD II B I I D 1 I 1 1 II I I I I I li I Habitat Manaaernient Plannina Efforts At the direction of the City Council, Carlsbad has undertaken preparation of a Habitat Managen Plan (HMPI for the City. The goal of the project is to develop an HMP which will become a rr component of the Open Space and Conservation Element of the General Plan. The HMP will pro direction about how best to conserve, use, and manage the City's biological habitat resources should result in an effective habitat preserve system. Decisions regarding the design of the pres! system are being directed by competent scientific research and driven by biological concerns. To d the HMP for the City of Carlsbad is incomplete although many of the preliminary studies necessar complete the HMP have been finished. Carlsbad Planning Areas The preliminary HMP studies divide the City into seven separate planning areas, see Map 5.4-3: Hat Management Planning Areas. The seven planning areas represent the portions of the City currently have the greatest biological value. Presented in Table 5.4-4 are the acreages of aggregi vegetation types by planning area, and presented in Table 5.4-5 are the sensitive species record planning area. The following provides a description of the biological resources in the seven plani areas. Plannina Area 1 (PA1 1 PA1 primarily consiists of the Buena Vista Lagoon in its western portion and Buena Vista Creek ir eastern portion. This 393-acre area is located at the northwestern border of Carlsbad, and is boun by State Highway 78 on the north and urban development on the south. The dominant cover tyc the open water of the lagoon. The eastern portion supports riparian scrub and non-native ani grassland. The planning area also includes some small patches of disturbed habitat. PA1 contains highly sensitive wetland habitats; the lagoons and saltmarsh and freshwater habi currently are statutorily protected from development under Section 404 of the federal Clean Water and Section 1600 of the California Fish and Game Code. Furthermore, Buena Vista Lagoon is mana as an ecological reserve area by the California Department of Fish and Game (CDFG) and therefoi already under state protection and management. The open water habitat of the lagoon supports a variety of fishes and provides foraging habitat numerous waterfowl. Sensitive wildlife species likely to occur in the lagoon or the associated s marsh include the Elelding's Savannah sparrow, light-footed clapper rail, California least tern, and s marsh skipper. Freshwater marsh provides habitat for two sensitive plant species; spiny rush, wt has been recorded from PAl, and San Diego marsh elder (R-1). Plannina Area 2 (PA4 PA2 contains 2,445 acres generally located east of Tamarack Avenue, northeast of El Camino R and north of Palomar Airport Road. The dominant vegetation in this area is coastal sage scrub chaparral, with relatively large patches of disturbed habitat interspersed with the sage scrub chaparral. This area supports one of the two remaining areas in Carlsbad with large, continuous stai of coastal sage scrub. Other notable features in PA2 include Lake Calavera and Squires Dam, ripar scrub and well devleloped oak woodlands in the southern portion of the area. The important habi in PA2 occurs in three large blocks; around Lake Calavera, the block of coastal sage scrub east o Rancho Carlsbad Golf Course, and the block of coastal sage scrub and chaparral around Agua Hedioi I I BIOLOGICAL RESOURCES 5.4- 1 HABITAT MANAGEMENT PLANNING AREAS e 5.4-12 VEGETATIONLAND COVER I 1 II 1 I 1 I 1 Coastal Sage Scrub Diegan Coastal Sage Scrub Maritime Succulent Scrub Dist Coastal Sage Scrub, Maritime Succulent Scrub Chaparral Southern Mixed Chaparral Chamise Chaparral Coastal Sage/Chaparral Mix Diaurbed Chaparral, Southern Mantime Chaparral, Coastal SageKhaparral Mix Native Grassland Non-Native Grassland Disturbed Grassland Saltwater Marsh Freshwater Marsh Ripansn Scrub Oak Woodland Sycamore Alluwal Woodland PLANNING AREA ACREAGES WTHlN PA1 PA2 PA3 PA4 PA5 PA6 PA7 NOT PAS WlTHl PAS 2,171 0 803 125 130 214 3 896 559 469 10 91 228 24 77 0 39 164 1,439 0 582 190 194 167 0 306 540 36 0 0 0 4 5 0 27 13 7 0 0 0 3 4 0 0 16 1,562 113 159 189 177 446 0 478 887 277 8 16 137 0 8 107 1 80 355 58 83 87 5 54 17 51 114 137 0 119 0 9 6 0 3 15 WILDLIFE PA1 PA2 PA3 PA4 PA5 PA6 PA7 Belding's Savannah Sparrow 1 California Lease Tern 1 Least Bell's Vireo 1 Light-Footed Clapper Rail 1 Orange-Throated Whiptail 3 2 San Diego Horned Lizard 2 Ashy-Spike Mass X X X X X California Adolphia X X X X X Englemann Oak X X San Diego Golden-Star X San Diego Thorn-Mint X X Spiny Rush X X X X Summer-Holly X X X Wart-Stemmed Ceanothus X X X X California Gnatcatcher 16 6 7 13 40 PLANTS X X X X Del Mar Manzanita Orcutt's Brodiaea X X Western Dichondra k = Observations FINAL MAS Environmentaf ImDact Re, CITY OF CARISBAD I I I I 1 I i 1 1 1 I i 1 B 1 I BIOLOGICAL RESOURCES 5.4- 1 scrub to the north and south, but these areas are rapidly urbanizing.

Portions Of The Citv Not Within A Planninq Area Approximately 15,545 acres of the City are not included within one of the seven planning areas. Approximately 9,783 acres are developed with another 3,078 acres consisting of disturbed habitat, active agriculture and golf courses. In addition, approximately 2,684 acres consists of native habitats including 723 acres of coastal sage scrub (including disturbed sage scrub and maritime succulent scrub), 553 acres of chaparral (including disturbed chaparral, southern maritime chaparral and coastal sage/chaparral mix), 1 6 acres of native grassland, 887 acres of non-native/disturbed grassland, 80 acres of saltwater/freshwater marsh, 11 4 acres of riparian scrub, 15 acres of oak woodland and sycamore alluvial woodland, 200 acres of eucalyptus woodland, 30 acres of open water, and 66 acres of disturbed wetlands. Although sensitive habitats are included in the portions of the City not covered by a Planning Area, the majority of these areas have already been protected through existing project approvals, Federal, State or Local Regulations (R-1 I. 5.4.2 Basis for Determinina Sianificance The project will have potentially significant impacts if it will: 1. 2. 3. 4. 5. 5.4.3 Implementation of the updated General Plan will result in additional development within the City. The new development will occur in undeveloped areas resulting in the reduction of sensitive habitats. AS the majority of the City's existing development is located in the western portion of the City, most of the future growth will occur in the east, where large areas of undeveloped land support a variety of sensitive habitats including coastal sage scrub and riparian habitats. These habitats support the federally-listed California gnatcatcher and least Bell's vireo respectively. Further, sensitive plant species potentially impacted by new development in the east include California adolphia, ashy spike moss, wart stemmed ceanothus, summer holly, and Del Mar manzanita. The following is a discussion. of potential impacts by planning area. Plannina Area 1 (PA11 PA 1 primarily contains highly sensitive wetland habitats: Buena Vista Lagoon, and saltmarsh and freshwater habitats. Portions of this planning area are planned for residential and non-residential development under the updated General Plan. The sensitive habitat areas identified in PA1 are currently protected from development under Section 404 of the Federal Clean Water Act and Sections 1600 of the California Fish and Game Code.

The City is currently working with the Fieldstc I I I 1 I 8 I 1 8 ’ li t BIOLOGICAL RESOURCES 5.4-1 1 FINAL MASTER Environmental lmoact Renort Company to preserve a portion of this planning area. Preservation of Coastal Sage Scrub habitat in PA7 is essential to maintenance of regional linkages as well as maintenance of a viable gnatcatcher population within the City. The updated Ger.dral Plan includes e znsive programs and strategies designed to support the development of the City's HMP. Furt- I, new general plan policies ensure coordination of habitat planning efforts with Federal, State and local jurisdictions. These programs will serve to mitigate potential impact to biological resources and will further serve to implement the City's policy for the preservation and protection of resources. The updated General Plan incorporates the Open Space and Conservation Resource Management Plan (OSCRMP). The OSCRMP designates future primary open space acquisition priorities. The OSCRMP identifies open space for the preservation of plant, animal life and habitat as a top priority. The updated General Plan designates 5,781 acres as open space to implement the OSCRMP. This designation expresses the City's general intent to optimize natural resource values throughout the open space system and to maximize the protection and mhancement of wildlife and habitats within various preserves. One of the primary priorities of the OSCRMP is greenways. Greenways in Carlsbad will serve several functions including providing for: wildlife corridors; buffers adjacent to habitat preserves; recreation areas; and viewsheds (R-3). The four major oreenways that are proposed as part of the updated General Plan, include the following: 0 CITY OF CARLSBAD An east-to-west greenway connecting from an adjacent open space corridor, trail connection and park in the City of San Marcos via the future Carrillo Ranch Park site, the future Alga Norte Community Park site, the future Zone 19 Community park site, to the Poinsettia Park site. This greenway will also provide connections to two future school sites. A north-to-south greenway running from Lake Calavera, past the Zone 14 school site, along Agua Hedionda Creek, crossing Palomar Airpcrt Road at the future intersection with Melrose, to the Carrillo Ranch park site. A generally east-to-west connection from Agua Hedionda Lagoon, through the proposed Veterans Memorial Park and the Evans Point development to Lake Calavera. A number of smaller or less complete greenways will be completed throughout the City linking together key environmental features including lagoons, large open space areas, nature preserves, City parks, and providing open space connections to surrounding cities. 0 0 0 Although the General Plan designates substantial open space and establishes effective wildlife corridors through the greenway system, the acreage of wildlife habitat will decrease substantially as buildout of the City proceeds according to the updated General Plan. The ability of the area to support sensitive plant and animal species will be reduced. Sensitive habitat and animal and plant species in Carlsbad will be significantly impacted. These impacts will be partially offset by implementation of the City's Open Space and Conservation Resource Management Plan, and General Plan Open Space and Conservation Element; participation in the Fieldstone Habitat Conservation Plan; involvement in the North County Multi-species Habitat Conservation Planning group; and through continued multi-species habitat management planning efforts. 5.4-1 8 BIOLOGICAL RESOURCES FINAL MAS1 Environmental Impact Rei CITY OF CARLSBAD I i i 1 I I II 1 II I 0 6 I B 1 1 1 I On March 25, 1993, the California gnatcatcher was listed by the U.S. Secretary of the Interic "threatened" under the Federal Endangered Species Act. The listing was effective immediately. T are no vested rights under the Endangered Species Act, thus all discretionary and ministerial per and all development, construction, grading or clearing in reliance on previously approved permi affected. Violations of the Endangered Species Act by taking habitat can result in substantial fines penalties imposed lby the USFWS. Because of the listing of the gnatcatcher, development undei updated General Plan will be constrained. The City is currently working with the USFWS and C thought the Natural Community Conservation Planning (NCCP) Program to resolve the issues. Fu the City of Carlsbad is working with other North County agencies through the North County Wi' Multi-species Habiitat Conservation Planning (MHCP) effort. The MHCP will ensure reg coordination of habitat planning. Finally, the City of Carlsbad has been working to complete the I for the past two years. The City's HMP will establish direction about how best to conserve, use, manage the City's biological habitat resources and should result in an effective habitat pres1 system. The City's HMP will be consistent with the States NCCP program and the North Coi MHCP. The gnatcatcher will be protected in the City by federal regulation, the inclusion of design Open Space in the General Plan, and preparation and implementation of a Multi-species Hal 1 Management Plan. Impacts of Implementing the Carlsbad Trail System The Carlsbad trail system has been included in the updated General Plan. The trail system consisl approximately 74 miles of pedestrian, bicycle, and joint use trails. See Map 5.4-4: Carlsbad System Map, for ,the location of proposed trails. There are three types of trails included in proposed system. The first includes a fully improved, handicapped accessible, paved trail which w be used in the most urban and heavily used trail sections. The second trail type would be unpaved is intended to be only minimally improved to allow a more rural aesthetic trail. The third trail would use the sidewalk and bike lanes in the road right-of-way as a trail and would be used only wl aligning the trail in a separate right-of-way was not possible. Approximately 61 miles will be unpa hiking and bicycle paths, approximately 11 miles will utilize sidewalks and bike lanes; approximately 2 miles will be paved pedestrian and bike paths (R-3). Direct impacts due to the trail system may occur as a result of the sensitive resource or loss of habitat for the sensitive species. Indirect impacts may occur as a result of the close placement oft to areas used by the sensitive species. Close proximity of human activity associated with a t system may cause some species to leave the area. A synopsis of the potential impacts to sens biological resources is included in Table 5.4-6: Carlsbad Trail SystemIMitigation Summary (R-2). ' segments not incliuded in this table were concluded to have no significant impacts to biolo! resources (R-2).

In 1960, a few ) after incorporation, the City‘s population was under 10,000 people. By 1970, the City‘s popul< had increased to almost 15,000. During the 1970’s the areas surrounding the City (most notabl La Costa area) began to develop. Some of these areas were annexed into Carlsbad and the C population doubledl. In 1980, the U.S. Census indicated that the population was 35,490. North Diego County (including Carlsbad) experienced a development boom in the 1980’s and employr centers and housing increased, The Carlsbad population increased by 77 percent between 1980 1990 to 63,126 persons. By 1992, the population reached approximately 65,700 people (R-1). The majority of Carlsbad residents are between 35 and 59 years of age. Approximately 16 per of the population is under the age of 18 and approximately 14 percent of the population is 65 y of age or older. The median age of the City’s population is 32.2 years of age which is older thar County-wide median age of 28.8 years of age. The median income for Carlsbad is approxim: $41,015 in 1987 dollars which is higher than the County median income of $37,900. Only 31 per (or about 10,000) of Carlsbad households fall below the County median income (R-1). Housing In 1980, Carlsbad contained 15,352 dwelling units. By 1990, housing increased by 77 perce Carlsbad to 27,249 dwelling units. In 1992, housing within the City reached 28,078 dwelling u Approximately 58 percent of the city’s housing stock is single-family homes and approximatel) percent is multi-family homes. Mobile homes compose approximately four percent of the hou stock. Recent construction trends in the last ten years have resulted in the development of r single-family homes than rnulti-family homes (54 percent and 44 percent, respectively). The condition of housing in the City is primarily good. Nearly 80 percent of Carlsbad’s housing is than 20 years old and the City has only a small stock of older homes. The older homes are prim located in the older northwest quadrant of the City. Approximately five percent of the total hou stock is substandard and the majority of the substandard housing is owner-occupied (R-1 I. Jobs-To-Housing Balance The Jobs-To-Housing Balance refers to the relationship between the availability of employr opportunities and housing to accommodate employees within a given city. The relationship betw jobs and housing hias been unbalanced in Carlsbad during recent years. Although significant hou has been developed in Carlsbad in the last ten years, the new housing has primarily been compc of luxury single-family homes. The new housing, in addition to the coastal setting, have attrac affluent families from other parts of San Diego County. Many of the new households retain 1 former jobs and commute to other areas. Carlsbad provides many employment opportunities in retail, industrial, arid service sectors. These employment sectors traditionally offer a lower wage as a result, many people employed within Carlsbad must seek housing in the surrounding commun where housing costs are lower (R-1). 6 FINAL MASTER Environmental Impact Remrt Growth Management Program The City developed a Growth Management Program which was ratified by Carlsbad voters in November 1986. The Growth Management Program establishes performance standards for public facilities, a population limit of approximately 135,000 persons, and a housing limit of approximately 54,600 dwelling units. The Growth Management Program was analyzed for potential housing impacts when it was developed. The analysis found that the Growth Management Program would not significantly impact the Regional Housing Needs or the Housing Element because the City's housing needs and fair share goals will continue to be met. The purpose and intent of the Growth Management Program is to provide quality housing opportunities for all economic segments of the community and to balance the housing needs of the region against the public service needs of Carlsbad residents and available fiscal and environmental resources. 5.5.2 Basis for Determinina Sianificance The project will have potentially significant impacts if it will: 1. 2. 3. 5.5.3 Environmental Imr>act Buildout of the updated General Plan will add a maximum of 25,389 dwelling units to the 27,249 dwelling units existing in 1990 for a maximum total of 52,638 dwelling units. Based on an average household size of 2.31 78 persons per dwelling unit (R-21, buildout will add approximately 58,878 persons to the 63,126 persons residing in Carlsbad in 1 990 for a total population of 122,004 persons. The City's population could increase by 93 percent between 1990 and 2010 (when buildout is assumed). Table 5.5-1 : Population and Housing Growth, summarizes the increases in population and housing. Table 5.5-1 also shows San Diego Association of Government (SANDAG) Series 7 population and housing forecasts prepared for 2010. The Series 7 housing and population forecasts for the City of Carlsbad are less than the population and housing resulting from buildout of the updated General Plan at 2010. The Series 7 forecasts are based on nearly the same land use densities contained in the updated General Plan but the Series 7 forecasts assume that buildout will occur sometime after 201 0. The environmental analysis performed in this EIR assumes that buildout will occur at 201 0 to estimate the "worst case" impacts resulting from the updated General Plan. In reality, buildout of the Carlsbad General Plan will probably not occur until after 201 0 and the Series 7 forecasts may be more accurate. CITY OF CARLSBAD Result in non-compliance with population and housing allocations for the region. Displace a large number of people.

The area was predominantly utilized for agriculture but achieved SI fame for local mineral water wells and the mild sea coast climate which was ideal for the grow seeds, bulbs, and a variety of flowers. From the inception of Carlsbad, until well after incorpora as a general law ciity in 1952, it existed as a quaint village-by-the-sea. However, following a sc of annexations which begun in the 1960's, the City began to grow gradually in area and populal From its original 7.5 square miles and 7,000 people, the City grew to its current size of 42.2 sqL miles and 65,700 people. In addition to the original village, the City now includes an internationally noted resort and surrounc residential neighborhoods, the most active general aviation airport in San Diego County, a 2,000 + i campus-industrial corridor, a million-plus square foot regional shopping mall and a major auto mall \ over 20 dealerships;. Related Documents and Land Use Policies Several existing documents and land use policies govern future development and land use within City of Carlsbad. These documents include the General Plan, the Zoning Ordinance, Gro Management Plan, the City's six Local Coastal Programs, McClellan-Palomar Airport Comprehen, Land Use Plan, and numerous master and specific plans. AdoPted General Plan The General Plan adopted in 1972 presently guides all development within the City boundaries. . Land Use Element of the General Plan defines land use categories and establishes developm intensity limits. The Land Use Element also establishes the distribution of the land use categorie5 illustrated in Map 5.6-1: General Plan Land Use Map. Table 5.6-1: 1990 Land Use Categories Development, summarizes the acreage of each land use category and the percent of each land category that was developed in 1990. Around 68 percent of the City is undeveloped, with remainder (32 percent) being developed with a variety of land uses. The percentage apportionm of the City's total acreage in 1990 was 55 percent Residential uses, 17 percent Non-residential u (commercial and inldustrial), one percent Mixed Use, and 17 percent Open Space. The remaining percent of the land area was designated for Schools, Government, Transportation Network (roads railroad), public utilities, and public rights-of-way. As shown in Table 5.6-1 : 1990 Land Use Categories and Development, 40 percent (5,638 acres the existing residentially designated land area is developed with approximately 27,249 dwelling ur Of the existing non-residential land area, 25 percent (1,066 acres) is developed.

The (PI) designation inclu areas suitable for industrial development, including manufacturing, warehousing, storage, research development and utility uses. The Professional and Related (0) designation includes 221 gross acres which are sparsely distribi throughout the City. Approximately thirteen percent of this designation is developed with (0) I uses. Planned Industrial land uses form the City's centralized industrial corridor which surrou Palomar Airport and extends in a broad band generally to the eastern and western City limits. Tt exists 1,692 gross acres of Planned Industrial designated land. Approximately twenty-two per( (379 acres) of the City's Planned Industrial designated lands are developed. Mixed Use The existing Carlsbad General Plan includes several areas which are under combination land designations (referred to as Mixed Uses). The Mixed Use designation is assigned to areas which in the early planning stages and for which the most appropriate land use designation has not b determined. A specific plan is required to be prepared prior to the development of any property wl has this designation. The Mixed Use designations are subdivided into Non-Residential and h ResidentiaVResidential categories. The Non-Residential Mixed Use designations include: PI/RS/C/TS/U, PI/O, and TS/C. Non-Reside! Mixed Uses comprise 884 gross acres of the City. Of this Non-Residential Mixed Use acre approximately 21 4 acres are developed. The majority of this developed Non-Residential acreag located immediately north of Palomar Airport in the Carlsbad Research Center and at the 1-5 Poinsettia Lane interchange. The Noni-ResidentiaVResidential Mixed Use designations include: RM/O, RMH/TS, RH/O and RH/ (total 01 144 acres). None of this Non-ResidentiaVResidential Mixed Use acreage is curre developed. Non-Residential Reserve This designation indicates areas where planning for future land uses has not been completed or p for devdopment have not been formalized. Because all of the Non-Residential Reserve acreas located in proximity to Palomar Airport, it is not appropriate for residential development. Tt designated areas are currently under agriculture or other interim uses until appropriate land designations are established. There are 51 5 acres of land which are designated Non-Reside1 Reserve. None of this land is developed. Governmental Facilities Presently, 273 gross acres of land are designated for Governmental (G) uses. This classificatio land use designates areas currently used for major governmental facilities by agencies such as the ( county, state, or federal government. Facilities within this category include uses such as t buildings, libraries, maintenance yards, police and fire stations and airports.

These land use designations represent both existing and proposed school sites necessary to serve the planning area. Currentfy 525 gross acres are designated for Schools. Developed school sites cover approximately 1 66 gross acres. Open Space The Land Use Map shows the generalized boundaries of presently designated and planned open space including City parks and special resource areas. The Open Space (OS) designation includes 4,281 acres of land. The majority of the Open Space land is composed of Carlsbad's three lagoons (Buena Vista, Agua Hedionda and Batiquitos) and their associated tributaries. Other major open space areas include Calavera Lake and the Veteran's Memorial Park site. Public Utilities This category of land use designates areas either being used or which may be considered for use for public or quasi-public functions. Such functions include: the generation of electrical energy, treatment of waste water, public agency maintenance storage and operating facilities or other primary utility functions. The Public Utility (U) designation covers 158 acres of land of which 130 acres are developed. Included within this designation are the San Diego Gas & Electric Power Plant and the Encina Wastewater Treatment Plant. Master PlansEoecific Plans The adopted General Plan also establishes a variety of Master Plan and Specific Plan areas throughout the City. These plans provide land use specifications and regulatory control for areas of the City which have unique characteristics. Zonina Ordinance The Zoning Ordinance is one of the primary legal devices to implement the General Plan. State law requires that the Zoning Ordinance be consistent with the General Plan. The Zoning Ordinance sets forth standards for the development of land uses of the General Plan. The land use zones addressed within the Zoning Ordinance include broad categories of Residential, Commercial, Off ice, Industrial, and Open Space land uses. Growth Manaaement Plan To ensure that adequate public facilities and services are guaranteed at all times as growth occurs, the City developed a Growth Management Plan which was ratified by the City voters in November, 1986. The Growth Management Plan establishes performance standards for eleven public facilities (city administration, library, wastewater treatment, parks, drainage, circulation, fire, open space, schools, sewer collection and water distribution). As part of the City's Growth Management Program (1 986) a dwelling unit limitation was established for each of the four quadrants of the City (the intersection of Palomar Airport Road and El Camino Real divides the City in four quadrants). To ensure that residential development through buildout of the City does not exceed the quadrant limits (Le; NW 5,844 DUs, NE 6,166 DUs, SW 10,667 DUs, and SE 10,801 DUs), Growth Management Control Points, as shown in Table 5.6-3: Residential Land Uses, CITY OF CARLSBAD 5.6-6 LAND USE Residential Density Range Land Use Low Density (RL) 0 -J 1.5 du/ac Llow-Medium Density (RLM) 0 - 4 du/ac - 8 du/ac Medium Density (RM) 4 Medium-High Density (RMH) 8 - 15 du/ac 1 I II Growth Management Control Points 1 du/ac 3.2 du/ac 6 du/ac 11.5 du/ac \ TABLE 5.6-4 LAND USE COMPATIBILITY WITH PROJECTED ANNUAL COMMUNITY NOISE EQUIVALENT LEVELS PRODUCED BY AIRPORT OPERATIONS LAND USE 55 60 65 70 75 1 Outdoor Amphitheaters 2 Nature Preserves, Wildlife Preserves, Livestock Farming Source: Draft Comprehensive Land Use Plan, McClellan-Palomar Airport March 1993, as revised.

Adoption imp1eme:ntation of the updated General Plan Land Use Element will add approximately 45,584,1 square leet of Non-Residential uses for a total of 59,106,837 square feet at buildout. The juxlaposition of land uses of the updated General Plan are regarded as compatible. Significan severe impacts to public health, safety and welfare through buildout of the General Plan are anticipated. The conversion of existing undeveloped land to urban uses will result in a substar change to the design character and form of the City. 1 LAND USE 5.6 / L I 5.e I 5 In 00 - 8 88888~~$R~Om” --FCC 5.6-12 FINAL MASTE CITY OF CARLSBAD Environmental lmnact Rem The City's Growth Management Plan mandates that all future development projects preserve ai maintain a minimum of fifteen percent of the total unconstrained land area per project as open spac Accordingly, this minimum percentage of open space per project will be achieved through buildout the City. Related IDocuments and Land Use Policies 1 I I 8 1 1 I I I I i il 1 II I 1 1 Adooted General fm As shown on the Proposed Land Use Map, the proposed General Plan creates four new land u designations (Regional Commercial- RC, Tourist/Recreation Commercial-TR, Village-V and Unplann Area-UA), and eliminates several land use designations (Intensive Regional Retail-RRI, Extensi Regional Retail-RRE, Regional Service-RS, Travel Service-TS, Recreational Commercial-RC, Cent Business District-CBD, PI/RS/C/TS/U, and Non-Residential Reserve-NRR. The proposed land L changes include the following: 1. 2. Designate an additional 1,500 acres on the Land Use Plan Map as Open Space (OS). Dlelete Intensive Regional Retail (RRI), Extensive Regional Retail (RRE), and Regional Serv (RS) land use designations and reclassify to new Regional Commercial (RC) designation. Delete Travel Service (TS) and Recreational Commercial (RC) designations and reclassify new Tourist/Recreation Commercial (TR) designation. Delete Central Business District (CBD) land use designation and reclassify to Village designation. 3. 4. 5. Delete the Carlsbad Research Center's mixed land use designation (PI/RS/C/TS/U) i risclassify a!; Planned Industrial (PI). Delete the Non-Residential Reserve (NRR) land use designation and reclassify to new Unplani Area (UA) designation. 6. The major proposed land use change is the addition of 1,500 acres of Open Space to the Land I Map. Designated Open Space will increase by six percent. Some of this additional Open Space is F of approved projects. The addition of this approved Open Space acreage to the Land Use Map will affect buildout of the City. Other land designated as new Open Space is constrained (undevelopal Open Splace which was identified through the City's Growth Management Program (Local Faci Management Plans). Since this additional constrained Open Space acreage was already accounted in City buildout projections, it will not affect the buildout potential of the City. The other proposed I use changes listed above are administrative in nature (land uses will be renamed and remain at same intensity) and will not affect the buildout acreage of the City. The proposed major Land Use Element policy additions include: 1. Allow density increases, above the maximum residential densities permitted by the Gen Plan, to enable the development of lower-income affordable housing. (Land Use Eleml I Residential Policies, (2.3.) - I LAND USE 5.6-' FINAL MASTER Environmental ImRact Report 2. CITY OF CARLSBAD Require residential development to achieve the minimum density stipulated under the applicable general plan designation unless approved by a general plan amendment. (Land Use Element, Residential Policies, C.2.) Require new master planned developments and residential specific plans to provide usable acres to be designated for community facilities such as daycare, worship, youth and senior citizen activities. (Land Use Element, Residential Policies, C. 13.) Require all new master plans and residential specific plans to provide a neighborhood commercial site within the plan area. (Land Use Element, Commercial Policies, C.1 .b.) 3. 4. The proposed land use Policy C.3, allows density increases above the maximum residential densities permitted by the General Plan to enable the development of affordable housing. This policy is necessary to ensure that the Land Use Element is consistent with Programs 3.7.a. (Density Bonus) and 3.7.i. (Mechanism for Granting Density Increases) of the City's updated Housing Element (October 22, 1991 1. Potential adverse land use impacts to surrounding properties associated with this new policy are mitigated by the policy itself. Specifically, the policy requires that any request for a density increase be reviewed relative to (1) a project's compatibility with adjacent land uses, (2) compliance with specific locational criteria, and (3) the adequacy of public facilities. In addition, any future projects processed with a density increase shall be required to undergo detailed environmental review. The potential for Land Use policy C.3 to increase the total number of residential units projected within the City through buildout is not anticipated. This conclusion is based upon the finding that a number of residential projects have been approved at a lower density than permitted by the General Plan. All of the unused units available from this source have been deposited in what is referred to as the City's excess unit bank. All units within the excess unit bank are prioritized for the development of affordable housing. There appears to be an adequate number of dwelling units within the excess unit bank for the City to meet its affordable housing obligations without exceeding the General Plan residential buildout projections, no land use impact will occur. Proposed Land Use Policy C.2., requires residential development to achieve the minimum density stipulated under the applicable General Plan designation, unless approved by a General Plan amendment. This policy will ensure that residentially designated sites are developed at densities consistent with their General Plan designations instead of being underutilized or developed below the minimum density of the designation's range. In that this policy will not result in an increase in development intensity or a change in use type, it will not impact the public's health, safety, or welfare or character of the community. Proposed Land Use Policies C.13. and C.l .b. will require new master and specific plan developments to provide sites for community facilities (daycare, worship, youth and senior citizen activities) and neighborhood commercial uses. The objectives of these proposed policy additions include: (1 ) creating more self-contained communities (2) ensuring that sites for such needed community facilities are clearly identified early on in the planning process, thereby mitigating potential land use compatibility impacts, (3) decreasing traffic trips, and (4) reducing air pollution emissions. These objectives, as implemented through these new Land Use policies will function to positively affect the character and form of each master/specific plan community. The provision of necessary community facilities in proximity to residential neighborhoods will also positively affect the health, safety and welfare of neighborhood residents. 5.6-14 LAND USE FINAL MAST Environmental Impact ReD CITY OF CARLSBAD Zonina Ordinance The City's Zoning Ordinance is consistent with the updated General Plan. Accordingly, revision! the Zoning Ordinance are not deemed necessary. However, amendments to the Zoning Map necessary to revise the Open Space zone boundaries, associated with the addition of 1,500 acre Open Space to the Land Use Map, and to rezone specific properties to be consistent with administrative land use designation revisions. The updated General Plan will not require the revision or amendment to any of the exis Master/Specific Plan boundaries or land uses. The updated General Plan Land Use Map has howt been amended to designate 1,500 additional acres of open space, A significant percentage of open space is from previously approved Master Plan projects. The addition of this open space to Land Use Map will ensure consistency between the General Plan and existing Master and Spec Plans. Growth Manaaernent Plan As discussed above, the affordable housing density increases, which would be allowed thro Residenlial Policy C.3., will not result in an increase in the total number of dwelling units permi through the City's Growth Management Plan.

Carlsbad's transportation systei generall!! meandering, due to the presence of natural topographic constraints (e.g., steep hills, lagol and marimade features (e.g., airport). Only the more densely developed redevelopment area in Northwest quadrant contains a more traditional grid-like street system. Transportation in the Cii primarily auto-oriented; however, the adopted Circulation Plan provides for automobile, truck, bicj pedestrian, and public transit modes. In addition, because of its location between Los Angeles and Diego, the City experiences a significant amount of through-traffic. Definitions Terms and concepts used in the traffic analysis discussion are defined below. The functional classification of a roadway refers to its primary function, either mobility or acces property. Higher classes of roadways (e.g., prime and major arterials) function mainly to carry throi traffic and to provide a direct connection to the freeway system. Collectors typically feed local tri to the arterial street system. Local streets provide direct access to abutting land uses. The design standaird refers to the roadway specifications, including roadway cross-section, de speed, capacity, grade and curvature, surface type, and traffic controls. The typical roadway cr section iJSed for the various functional classifications of Circulation Plan roadways in Carlsbad ar follows: - Artlerial Classification Riaht-of-Wav/Paved Width Prirne Arterial 126 ft/l06 ft Major Arterial 102 ft/82 ft Secondary Arterial 84 ft/64 ft Collector 60 ft/40 ft Local Street 60 ft/40 ft e Variances to these design criteria may be allowed under special conditions. Hillside streets designed on a case-by-case basis subject to established guidelines (R-1). Average Daily Trafic (ADT) level reflects the average 24-hour traffic volume (both directions) given location for some period of time less than a year. Level of service (LOS) analysis is used to evaluate congestion and associated delay on streets an intersections. The level of service reflects the ability of traffic to flow on that street. There art recognized levels of service represented by the letters "A" through "F". A detailed description of le of service is providled in Table 5.7-1 : Levels of Service Descriptions. The level of service of an intersection can be an indication of the delay which can be expected on street network. For this reason, the City determines level of service by means of Intersection Cap2 Utilization (ICU) analysis for signalized intersections.

These include El Camino Real (north/south) and Palomar Airp Road (east/west) which run through the center of the City, and Rancho Santa Fe Road, which ri along the southeastern boundary of the City. Information regarding the existing street circulation system and conditions in 1990 was taken from ' 1990 Growth Management Plan Traffic Monitoring Report (see Appendix F). This report analyzed d for 37 key intersections and 18 key mid-block locations. The mid-block analysis indicated that roadway segments were operating at LOS F during peak periods. However, Palomar Airport Road, e of Melrose Drive, was identified as operating at LOS E during the peak period. La Costa Aver between Piraeus Street and Saxony Road was found to be operating at LOS D during the peak peril The Paloimar Airport roadll-5 ramps and the La Costa Avenue/l-5 ramps also failed to meet the Grok Management performance standard. Since that time, improvements to the Palomar Airport Road, interchange have been completed. Improvements to the Palomar Airport Road/El Camino R intersection are estimated to be completed by August, 1994. Improvements to the La Costa Avenu 5 ramps have been funded and designed. They are expected to be completed in fiscal year 1995-! Intersections in urbanized areas tend to be the dominant factor in traffic operations. Thus, the anal of intersection levels of service at signalized intersections provides a more accurate indicatior system operations in urbanized areas.

The intersection of El Camino Real and Palomar Airport Road was the most critical intersection in study. The intersection of Palomar Airport Road and Business Park Drive was the second most cri intersection. The 'I 992 Monitoring Study showed an improvement in some of these intersection A 1992 report (R-4) indicated that the City contained 63 signalized intersections. Fifty-six of tl were owned and imaintained by the City. The remaining seven were maintained, or owned maintained, by Cal'Trans. This report, updated every two years identifies and evaluates the pote need for future traffic signals throughout the City. Truck Routes The City addresses truck traffic demands by the designation of specific posted truck routes. T routes alre designated by an adopted city ordinance. The truck routes must accommodate turns maneuvers by large trucks and connect with the freeway and arterial system. In addition, truck ro I CIRClJLATlON 5.7 I - FINAL MASTER Envikonmentallmoact Report CITY OF CARLSBAD are chosen to minimize noise, pollution, and safety impacts to residential areas. Current truck routes are shown on Map 5.7-3: 1990 Truck Routes. Parking Facilities The City has nine public parking areas in the Village Redevelopment section of the City. These lots are generally located around Carlsbad Village Drive and State Street and provide approximately 355 parking spaces. There is a general need for more parking in the Redevelopment Area during parts of the day. One park-and-ride site is located within the City limits at La Costa Avenue and 1-5. However, the site is owned and maintained by CalTrans. Alternative Modes of TransDortation Bicycles Bicycles are encouraged in the City as an alternative form of transportation. A citywide bike lane inventory completed in early 1993 (R-5) identifies the locations of all existing bicycle lanes. These lanes are shown on Map 5.7-4: 1993 Bike Lanes. In most cases, the bike lanes are present on both sides of the streets shown. Short segments of some streets have bike lanes on only one side because the streets are currently unimproved or because of on-street parking. Pedestrians The primary existing facilities for pedestrians in the City are sidewalks within the street right-of-way and controlled street crossings. Current City standards require the installation of sidewalks as a condition of approval for most developments (except hillside streets) (R-1 1. However, there are a number of locations, especially in the older sections of the City, where sidewalk facilities are deficient or were never constructed (R-6). The only complete trail segment currently existing is located along the northern edge of Batiquitos Lagoon. The trail consists of a paved pedestrian and bike path (R-7). Mass Transit North County Transit District (NCTD) currently provides local and express bus service in Carlsbad. The City has two transfer points for bus riders. One is on Grand Avenue near Washington Street. The other is the Plaza Camino Real Mall. Eleven bus routes currently serve some portion of the City. The current bus routes are shown on Map 5.7-5: 1993 Bus Routes (R-8). NCTD also provides specialized transit under the requirements of the Americans with Disabilities Act (ADA). This Dial-a-Ride service is provided for people who live within one-quarter mile of a regular fixed route (R-9). The City currently has no commuter rail or other rail service. Amtrak serves the Southern California area through the Oceanside station, but there is no Amtrak depot in Carlsbad. A general aviation airport, McClellan-Palomar Airport, is located in the center of the City. The airport's influence area is a wide band running east and west through the City. The areas surrounding the airport can generally be used only for industrial and supporting commercial uses due to restrictions related to health and safety issues. The Airport serves charter firms and other aircraft. It also provides passenger service to Los Angeles International Airport. 5.7-6 C I RCU LATlO N I I I I I I I I I I I I I I I 1990 TRUCK ROUTES &2 'h w TRUCK ROUTES CITY BOUNDARY -- SOURCE CITY OF CARLSBAO ENGINEERING DEPARTMENT I\ MAP 1993 EXISTING BIKE LANES B CITY BOUNDARY --- SOURCE CITY OF CARLSBAO ENGlNEERlNC OEPARTUENT MAP 5.7- 5.7-8 1 I I I I 1 I I I 1 I 1 I I I I 1993 BUS ROUTES E 'AM I -1 - BUS RGUTES TRANSFER POINTS - - CITY eCUNDARY XrJRCE CITY CC CARLSAD DlWlEERlNG DEPARTYMT WD KT0 1393 BUS RW E UAPS MAP FINAL MASTER Environmental ImDaet Report Regional Circulation Considerations As stated previously, the City's circulation system currently carries through-traffic from surrounding areas. Palomar Airport Road provides access to 1-5 from the east (San Marcos). El Camino Real provides north/south access from OceansideNista and from Encinitas. Carlsbad Boulevard (State Highway 101 ) also carries some regional traffic. Carlsbad roadways are particularly affected by regional traffic during commuting periods. Commuters often use Carlsbad surface streets to avoid congested traffic on 1-5. As these surrounding cities continue to grow, some Carlsbad arterials will carry more of this regional traffic. 5.7.2 Basis For Determining Sisnificance The project will have potentially significant impacts if it will result in the following Levels of Service: 01. Level of Service C or more on road segments or intersections during off-peak hours. 2. Level of Service D or more on road segments or intersections during peak hours. 5.7.3 Environmental lmeacts Streets and Traffic Control Roadways The San Diego Association of Governments (SANDAG) prepared traffic forecasts for the City of Carlsbad. These forecasts based the projections on buildout of the land uses established by the adopted Carlsbad General Plan (which are essentially the same as the land uses in the updated General Plan) and year 2010 regional traffic projections. The traffic projections for the City represent the "worst case" traffic that was projected to occur in 2010. Due to the current economic climate in California and subsequent decrease in development activity, actual traffic in 2010 is expected to be less than was projected. The source of the information regarding the future streets and traffic control system in Carlsbad is the "Circulation Implementation Program and Traffic Impact Fee Study" (TIF) prepared by the City Engineering Department in 1991 (see Appendix GI. This study was designed to develop updated traffic volume projections to guide the overall development of the City's Circulation Element of the General Plan. It utilizes the SANDAG traffic model projections for 2010 buildout. Elements of the study included a complete update of land use and circulation network assumptions, projections of future traffic and evaluation of the impacts of various alternative networks. Land Use and growth projections were evaluated for compatibility with adopted Local Facilities Management Plans (LFMPs- and alternatives were designed to evaluate the potential impact of such major missing circulation links. Among other things, the study evaluated the adequacy of the circulation system, identified circulation system deficiencies, and established a preliminary phasing program to ensure conformance with Growth Management Plan standards to buildout of the City. Evaluation of the adequacy of the Circulation Element involved comparisons of projected peak hour traffic volumes against planned roadway capacity for circulation roadway segments and intersections. The study indicated that, when fully constructed, roadway segments will be adequate to accommodate buildout traffic; however, 20 intersections will be severely impacted by regional through traffic over which the City has no jurisdictional control. These intersections are shown on Map 5.7-7: Impacted Intersections.

However, these designations can be changed or updated by amending the City ordinance should such a change be necessary. Parking Facilities The City requires new development to provide all required parking onsite. This requirement is sometimes difficult to meet in the Village Redevelopment Area. The Redevelopment Master Plan, currently under review, will provide for the creation of parking districts throughout the Redevelopment Area. A number of parking lots will be included, but specific locations have not yet been identified. In other areas of the City, parking requirements will continue to be met onsite. Alternative Modes of TransDortation Bic ycies The City’s Bicycle Plan calls for bike lanes to be provided on all primary, major, and secondary arterials. Bike lanes will be included in the street right-of-way, and will be supplied on both sides of the streets. The lanes will be provided as development occurs. Pedestrians A 1991 report (R-6) includes a program for future construction of sidewalk linkages throughout the City. This program emphasizes the need to complete these links on a systematic basis to achieve a City-wide uniform sidewalk network. The program also establishes recommended sidewalk prioritization lists for construction of needed sidewalks. The sidewalk priority list is intended to be used as a tool for planning future construction of the missing sidewalk segments. Some of these needed sidewalks will be provided as development occurs, while others may need to be provided by other means. A seventy-four mile Trail System has been approved in the City (R-71. The system includes pedestrian, bicycle, and joint use trails. A variety of surfaces will be provided, depending upon specific anticipated uses. As a condition of approval, proposed development projects must not preclude the provision of such trails. Mass Transit As buildout of the City occurs, mass transit will be more important to alleviate congestion on City streets. NCTD evaluates the need for service changes on a monthly basis. They monitor monthly trends in ridership and schedule adherence and the need forkondition of transit amenities (ea, shelters). They also monitor the information provided by the City regarding new development proposals, especially potentially large traffic generators (R-9). The North County Transit District currently has plans to provide commuter rail service in the City beginning in late October, 1994. The commuter rail service will provide transportation between Oceanside and San Diego with two stops in Carlsbad. Current plans include stops at Grand Avenue and at Poinsettia Lane. The Grand Avenue stop will include a small station at Grand Avenue and Washington Street. This station will also provide limited connection with bus routes and will include bicycle lockers. (Bikes will be allowed on trains and some busses.) The Poinsettia Lane stop will be CITY OF CARLSBAD 5.7-14 CIRCULATION FINAL MAS1 Environmental ImRact Rei CITY OF CARLSBAD I I I 1 I I I I 1 u i I II 1 I a platfoirm only. The planned service will include four southbound trains and one northbound during the morning peak hours and four northbound trains and one southbound train during the eve peak hours. NCTD currently anticipates approximately 2,000 total round-trip riders daily (R-g).Regi Circulation Considerations As discussed previously, the City's circulation currently carries a considerable amount of reg1 through traffic. Traffic projections indicate that it will carry even more through traffic in the fut The Regional Transportation Plan (RTP) establishes regional transportation policy for the San D region. It addresses all modes of transportation, including automobile, transit, bicycles, railroad aviation facilities. It identifies the facilities and programs which will be needed to meet the incre: travel demand through the year 201 0. The RTP addresses capital facility funding, transporta system management (TSM), transportation demand management (TDM), commercial airport site, air quality strategies. Some of the recommendations of the 1990 RTP include: I "Provision of additional capacity on some regional arterials "Expansion of bicycle network " Provision of commuter rail service between Oceanside and San Diego "Provision of High Occupancy Vehicle lanes on 1-5 +Improvement of traffic signal timing "Freeway ramp metering "Improved transportation demand management 1 The City's policy is to participate with other cities in addressing these issues. 5.7.4 - Level Of Sianificance Buildout of the updated General Plan will result in significant circulation impacts by 201 0. mitigation measures identified below are required to reduce the severity of the circulation impa Implementation of required mitigation will reduce significant impacts from City-generated traffic less than significant level; however, the impacts at the intersections shown on Map 5.7-7, will stil significant after the mitigation measures are implemented as a result of the cumulative effect of C generated and regional through traffic.

As I land is developed and redeveloped, cultural and paleontological resources are at risk. Paleonlology of Carlsbad The Lusardi Formation of the Cretaceous Age is the oldest fossiliferous rock unit within the City consistently produces significant fossils and consists of sandstones and conglomerates that deposited in a shallow sea that covered the region approximately 74 million years ago (R-2). The sandstones and siltstones of the La Jolla Group (Santiago Formation, Del Mar Formation) o Tertiary Age overlie the Lusardi Formation. This formation is approximately 45 million years olc has produced a large number of vertebrate and invertebrate fossils. This formation has a high pote for containing significant fossils (Map 5.8-1 : Potentially Significant Fossil Areas]. Quaternary Age alluvial deposits (Loma Linda Terrace Deposits) have the potential to COI fossiliferous rock from Pleistocene terrace deposits of not more than 2 million years in age. TI fossils .are also potentially significant. Prehistory of Cairlsbad (1 0,000 B.C.-1769) In 1 990, Regionall Environmental Consultants (Recon) updated the City's comprehensive recoi prehistoric cultural resources through a process of record search and mapping. At that time discrete site locations were identified (R-1 ). These sites, occurring throughout the City (see Map 2: Known Archaeologically Sensitive Areas), represent both the archaic (the San Dieguito Paleo-InL and La Jolla-Pauma complex) and the late prehistoric/protohistoric (Luiseno and Kumey occupations. The sites range from single isolated features to multi-component settlements indicz of long term and multi-cultural occupation (R-2). The following summarizes a discussion th; excerpted from the City of Carlsbad Cultural Resources Inventory prepared by Recon. The earliest documented inhabitants of the San Diego region are known in the archaeological rei as the San Dieguito people. Initially, these people were believed to have been big game hun however, they are better characterized as a hunting and gathering society. between the San Dieguito and the La Jolla-Pauma periods in San Diego County remains a topi debate among members of the archaeological community. The debate centers on the fate of the Dieguito. The question is whether or not the San Dieguito people continued to occupy the region I 7,000 years before the present (R-3, R-4, R-5, and R-6). In one of the two scenarios, the San Die( are replaced by an intrusive La Jolla culture; and in the second, the differences in the artifacts ecofacts are reflective of cultural and technological change among the group known as the 1 The transition I Dieguito. I In either case, at sites dating circa 8,000 years before the present, there is a change in the typE artifact:; that are represented at both inland and coastal locations in the region (R-7).

Perhaps the most noticeable difference between the La Jolla period and the San Dieguito period is that the La Jolla period people seem to have emphasized coastal resources, as evidenced by both settlement patterns and technological innovations. The coastal margin provided a vast array of maritime and estuarine resources, (in particular, shellfish and fish), while inland resources included seeds, fruits, and small game (R-8,R-S,and R-lo). The shift towards coastal resources, vegetable foods, and small land animals and away from large game hunting are seen as changes in the nature of the archaeological sites that are produced. The transitory behavior of populations dependent upon large game results in archaeological deposits that are ephemeral, both in terms of the amount of cultural debris that is left to analyze and the dispersed patterning of these sites over the landscape. This site development process is altered by the shift from large game hunting. The introduction of food that is easy to obtain and available in large quantities, results in sites with depth of deposit and variety in the artifacts present. These sites are generally clustered around the source or sources of the resources. The most recent prehistoric culture groups are generally known by the names of the Spanish colonial missions which had control over their fate. In the Carlsbad area there are three names that are used; Kumeyaay, the most generic; Northern Diegueno, after the Mission de Alcala, San Diego; and Luiseno, after the Mission San Luis Rey, Oceanside. Archaeologists also refer to these groups as part of the Millingstone tradition, based on the proliferation of milling implements and bedrock grinding locales in the archaeological assemblage. With the arrival of the Yuman speaking people circa 1200 years before the present came the introduction of ceramics, a closely knit clan system, a highly developed grinding technology, an elaborate and complex kinship pattern, rock art, cremation, and extensive trade networks into the Great Basin and Mexico (R-1 1 ,R-l2,and R-13). This cultural pattern appears to have relied heavily upon an economic system tied to the use sf the acorn and other plant products. Some of these plant foods required extensive processing before use, which is believed to be tied to the presence of bedrock and portable grinding elements in sites dating to this period. The dependence upon a plant based and seasonally available set of resources probably also contributed to the "settling" and development of more permanent villages and centralized settlement locations. This economic base apparently was able to support larger groups of people and these groups may have stayed in a specific village on a year round or nearly year round basis, with the result being the development of extensive archaeological sites such as the village of Palamai at Buena Vista Lagoon. The people in villages such as this were contacted by Spanish Colonial groups in the 1760's, setting in motion the gradual acculturation of Native American people to the ways of the colonizing group. . History of Carlsbad The history of Carlsbad began with Portola's colonizing expedition of 1764 which named Agua Hedionda (Stinking Water) Lagoon. In 1798, Mission San Luis Rey was founded and the area became part of the mission lands. In 1842, 21 years after Mexican independence from Spain and 9 years after the missions were secularized, the 13,000 + acre Rancho Agua Hedionda (original name San Francisco) and the 4,341 acre Las Encinitas Rancho were granted. In 1881 the California Southern Railroad reached the area and dry farming took over from cattle grazing as the main industry. The Lafayette Tunnison homestead established in 1882, was purchased by John Frazier in 1883. While drilling for irrigation water he intercepted a mineral water spring. The fame of the curative powers of the water spread and Frazier's Station became a destination for travelers. In 1886, the Carlsbad Land and Mineral Company was formed which laid out a townsite and speculative 5.8-4 CULTURAL and PALEONTOLOGICAL RESOURCES FINAL MAS Environmental Imnact ReJ CITY OF CARLSBAD I I I I I i I 1 1 I 8 R 1 I I 1 I 1 development began. The name Carlsbad was chosen to promote the spa character similar to tht at Karlabad, Bohemia. The hktory of Carlsbad may be divided into various periods or eras; the HispanidMexican (1’ 18461, pre-railroatl/early American (1 846-1 881 1, railroad/land boom (1 881 -1 8901, no growth (1 I 191 41, expansion (1 91 4-1 9321, depression (1 932-1 941 ), expansion and incorporation (1 942-pres (R-1). There are ai number of architectural themes present in historic Carlsbad structures to incl Carpenter Gothic, Craftsman, Mission, Monterey, Neo-Classic, Colonial Revival, Queen Anne Victo Spanish Eclectic, and Vernacular (to include Cottages/Bungalows). Rancho Los Quiotes is presc the only property ton the National Register in the City. An intensive historic survey conducted by Roth and Associates, dated February 18, 1990, designed to update and augment the findings detailed in the 1980 Regional Historic Preservation by Westec. Throuigh a combination of resource specific evaluation, sample survey, archival rese and community input, the numbers, characteristics, conditions, and significance of Carlsbad’s his resources was developed. Three hundred twenty-five (325) properties were identified as impor features in the loc<al architectural and historical growth of the community. The location and feat of the historic properties are located in Appendix H. Cultural1 Resource Guidelines The City of Carlsbad has developed guidelines for the treatment of cultural resources. These guide\ were adopted in 1990 and conform with City, State and Federal laws and with the Secretary of Interior’s Standards for Archaeology and Historic Preservation for Planning, Identification, Evaluation. The guidelines establish a standard of performance for investigations of cultural resoui and present a systematic method of preserving them. These guidelines pertain to cultural resoui from the prehistoric through historic periods and are implemented during compliance with the Califo Environmental Quality Act. For sites identified as important cultural resources according to CEQA criteria, potential advl impacts must be addressed.

The noise environment in the City of Carlsbac characteirized by various levels of natural, man-made, and mechanical noise generated from airboi mobile, and stationary sources. The majority of noise in the City is generated by mobile sourL including airport-related noise, railroad-generated noise, and noise generated by the freeways and ot circulation roadways. Also, noise is generated from urbanized uses, especially in the industrial arc of the City concentrated around McClellan Palomar Airport; in the Village where land use densities i intensities are moderate to high; and around the regional shopping center. Noise generation is minil or limited in the exclusively residential portions of the City, and in rural or undeveloped areas. Community noise levels are measured in terms of intensity and duration. The basic unit used express intensity is the decibel (dB). By using decibels, noise can be described in a numerical rai of 0 dB to 140 dB. This range is from the softest sound we can sense to a painfully damaging 11 sound. Decibels arle generally weighted to correct for the relative frequency response of the hun ear. For example, an A-weighted noise level de-emphasizes high frequencies of sound that are he by a dog, but not by a human. The normal range of noise levels we experience on a day-to-day b: ranges from 30 dBA to 110 dBA. Noise in the Community Noise Impact Range (40 dBA to 85 dk can cause temporary physiological and/or psychological effects. Noise is considered a "stressor" i may have serious irnplications in stress-related ailments. Substantial noise can interfere with spet communication and disrupt sleep. Table 5.9-1 : Typical Sound Levels in dBA, illustrates many of ' sounds that we experience on a daily basis. The predominant noise measures are the noise Equivalent Level (Leql, the Community Noise Equivalr Level (CNEL) and the Day-Night Average (Ldn), which are based on A-weighted decibels. The City Carlsbad utilizes CNEL to measure noise levels within the community. The CNEL carry weight penalties for noises that occur during evening hours from 7:OO p.m. to 1O:OO p.m. and at night frl 1O:OO p.m. to 7:OO a.m. of 5 and 10, respectively. Thus, the CNEL represents the daily no exposure averaged on daily and annual basis. Significant Noise Sources Two typts of noise sources are considered in the City of Carlsbad: mobile sources and station; sources. Mobile sources are typically transportation-related and include automobiles, aircraft, trail trucks, motorcycles, buses, off-road vehicles, and boats. Stationary sources of noise are geners those sources that are generated by specific land uses and may include industrial and commerc operations, construction activity, farming operations, concert halls, outdoor sporting events, lo stereos, and barking dogs. The noise sources that are considered most significant in the City Carlsbad are mobile sources of noise. However, stationary sources such as, commercial and industi activities contribute to the City's ambient noise levels. The following is a discussion of the signific: sources of noise.

The airport's current ar operaticin is approximately 235,000 aircraft. In general, land in the immediate vicinity of the air or undeir the take-off or landing approach is subject to noise levels which are unsuitable for reside development, schools, hospitals and other similar noise sensitive uses. Projected noise cont around the airport are provided in the Comprehensive Land Use Plan (CLUP) for McClellan-Palc Airport and have been included in this EIR (See Map 5.9-1: Comprehensive Land Use Plan (CLUP) for McClellan-Palomar Airport is to be a long-range master for the aiirport. For purposes of General Plan Land Use planning, the City of Carlsbad must assume the Comprehensive Land Use Plan (CLUP) for McClellan-Palomar Airport is a long-range master updated every five years, that reflects anticipated growth for the airport for at least the next tw (20) years. A review of current land uses under the General Plan update shows little noise impac existing uses. Stationary Sources of Noise Commercial and Industrial Uses The prirnary stationary noise sources are commercial and industrial land uses. Commercial industrial land uses that may generate noise in the community consist of private businesses provide a wide range of services in the community, These potential noise generating services incl the motorcycle raceway; automobile repair and service shops; manufacturing, warehousing, distributing operations; a sand and gravel extraction and processing facility; airplane and helico service i3nd repair lacilities; outdoor dining establishments; recycling facilities; and other busines Sensitive Receptor!; Sensitive noise receptors are, in general, areas of habitation where the intrusion of noise has potential to impact adversely the occupancy, use or enjoyment of the environment. Sensitive recep include, but are not limited to, residences, schools, parks, motels, hotels, public meeting roo churches, libraries, and hospitals. The City of Carlsbad considers residential uses particularly sensi to noise intrusion because residents are expected to use their homes for rest and relaxation, in wl higher levels of noise may interfere. Noise Standards The compatibility OF various land uses with noise is an important consideration in the land use plan1 and design process. Some land uses are more sensitive to the impacts of unwanted sound or ni than are others. For example, schools, hospitals, churches and residences are generally considc more sensitive to noise intrusion than are commercial or industrial activities. Table 5.9-2: Land Compatibility for Community Noise Environments, shows the general guidelines for acceptable nc exposures for existing and proposed land uses in the City of Carlsbad. The Land Use Compatib Chart is included in1 the Carlsbad Noise Guidelines Manual. The chart is used as a guide by the ( to determine the potential compatibility of land uses within a certain noise environment.

However, Chapter 1 of the Carisbad klunicipal Code (CMC) regulates noise from animals, and Chapter 8.28 oi (CMC) regulates noise emanating from motor vehicles and Chapter 8.48 of the Carl: Municipal Code, Limits Hours of Construction. The City does enforce California Penal C Section 41 5 when annoying noise occurs. Existing Noise Lewels To assist in the assessment of existing conditions, noise levels were measured. Noise measurem were taken at 23 locations throughout the City of Carlsbad. Criteria for site selection inch geographic distribution, land uses suspected of noisy activities and, proximity to transports facilities. Measurements represent motor vehicle noise from Interstate 5, State Route 78, and Circulation Element roadway network. Sensitive receptor locations monitored both single-family multiple-family residential units. The average noise level in a typical residential area, during the is 48.8 dBA. For a typical multiple-family area the noise level is 50.1 dBA. The areas with the hig noise levels are coimmercial land use areas, where the typical levels during the day are approxim: 65 dBA and about 53 dBA at night. These noise levels are considered slightly low for a commL the size of Carlsbad (R-1). In general, existing residential areas located in the Carlsbad Village a the freeways, prime arterials and major arterials are subject to noise levels in excess of those permi by current City policy for new development. Noise contours which depict existing noise levels for mobile noise sources including airport, freeway, prime arterials, major arterials, and collector streets, are presented in Map 5.9-2: Exi: Noise Exposure Map. The noise contours of this map have been prepared using a computer m which did not factor into the program topographic or structural barrier influences on noise lei Subsequently this noise contour map is used for planning purposes only. According to Map 5. noise contours have been prepared for all existing Circulation Element roadways in Carlsl Interstate-5 generates the greatest noise emissions. In addition, 1-5 impacts the greatest numb€ existing dwellings. There are a considerable number of existing single family and multi-family dwell1 which are impacted by freeway noise levels in excess of 65 dBA CNEL.

This additional development will result ii increase in traffic, and an increase in the associated noise levels in the City. The City's noise contour data were prepared by Nolte and Associates using the Federal High? Adminislration's (FHWA) methodology for vehicle noise prediction, as modified for CNEL, CALVENO energy curves which represent the noise output of typical California motor vehicles. purposes of developing Citywide noise contours, topographic or structural barrier influences on n levels were not included in the noise model. See Appendix J for 1990 and 201 0 noise contour d The roadways that were modeled included all Circulation Element roadways. The results of the n model were used to construct projected noise contours for the year 201 0. Map 5.9-3: Future N Exposure Contours, shows the projected noise contours. The contours depict an increase in noise levels along most Circulation Element roadways. distances to CNEL contour for these roadways are given in Appendix I. These data represent distances from the centerline of the road to the contour value shown. Future residential sites 1 levels above 65 CNEL adjacent to freeways, state highways, prime arterials, airport, or rail corri and future residential sites with roadway noise levels above 60 CNEL adjacent to all other Circula Element roadways, will be required to mitigate noise levels to meet the City noise standard. Distb from roadway centerline to the 60 CNEL contour will increase along Interstate 5, SR 78, Alga Rc Camino Vida Roble, Carlsbad Boulevard, College Boulevard, El Camino Real, El Fuerte, Carlsbad Vi1 Drive, Olivenhain Road, Palomar Airport Road, Poinsettia Lane, Rancho Santa Fe Road, and Tamai Avenue. The 60 CINEL contour will extend beyond the road right-of-way and into adjacent land i in most instances. Existing and planned noise-sensitive land uses existing adjacent to these roadw may be exposed to noise levels above City, State, and Federal standards. With proper site des planned residential land uses can accommodate residential development and be compatible with City's exterior noise standard. Mitigation through project redesign and construction or a noise bai (berm, wall, or combination berm/wall), are the most common ways of alleviating traffic and rail nc impacts. For existing noise-sensitive uses noise mitigation is difficult. The City will continue to v\ with residents to identify ways to reduce noise in their neighborhoods and will assist in formula several assessment districts to pay for noise barriers.

Construction noise is a short-term impact on ambient noise levels. Noise generated by construction equipment and construction activities can reach high levels. Enforcement of the City of Carlsbad Noise Ordinance that limits the hours of construction to normal weekday working hours should minimize any potential impacts. 5.9.4 Level of Simificance Although aircraft noise impact on incompatible uses can be reduced, it cannot be eliminated. Both the Noise Element and the Comprehensive Land Use Plan (CLUP) for the Airport are designed to mitigate the effects of aircraft noise from the Airport. When implemented, they will have beneficial impacts on the aircraft noise environment, reducing impacts to less than significant. Traffic noise will increase as the City approaches buildout. These noise impacts can be reduced with proper design and mitigation. Increased rail service through the City will result in increased noise levels along the rail corridor. Noise impacts on new development can be mitigated through proper design. 5.9.5 Mithation Measures The following mitigation measures will serve to reduce impacts from implementation of the proposed General Plan to less than significant: 1. Control harmful or undesirable sounds through the planning and regulatory process with emphasis on noise/land use compatibility planning. (Noise Element, General, C. 1 .I Review all development proposals, both public and private, for consistency with the policies of the Noise Element. (Noise Element, General, C.2.)

The City shall continue to enforce project conditions of 'approval related to noise control. (Noise Element, General, C.4.) Periodically review the noise contours contained in the Noise Element. Substantial changes in traffic patterns or the availability of new noise contour data may indicate the need for revisions. (Noise Element, General, C.8.) Require the use of project design techniques, such as, increasing the distance between the noise source and the receiver; placing non-noise sensitive uses such as parking areas, maintenance facilities, and utility areas between the source and the receiver; using non- sensitive structures, such as a garage, to shield outdoor spaces from a noise source to minimize noise impacts during any discretionary review of a residential or other noise sensitive project. (Noise Element, Land Use, C.3.) Enforce the policy of the City that sixty (60) dBA CNEL is the exterior noise level to which all residential units should be mitigated. Sixty-five (65) dBA CNEL is the maximum noise level to which residential units subject to noise from McClellan-Palomar Airport should be permitted. Additional disclosure actions (easements, deed restrictions, recorded notice, etc. 1 may be required of developers/sellers of noise impacted residential units. 2. 3. 4. 5. 6.

These zones are mostly limited to the floodways of the major drain; leading 'to the three coastal lagoons of the City: Buena Vista, Agua Hedionda and Batiquitos Lago The 1 OO-year flood areas are shown on Map 5.1 0.1-1 : Carlsbad 1 OO-Year Flood Boundaries addition, the areas subject to flooding within Carlsbad are noted and mapped as Special Flood Ha Areas 01-1 the City's Zoning Map. Any development in these areas must be approved by a Special Permit (SUP). The coastal edge of the City is subject to coastal processes in the form of sea erosion, storm wave related shoreline impacts (requiring seawalls for protection of residences public infrastructure) and episodic storm surges that can overtop the barrier beach in front of P Hedionda Lagoon. Catastrophic dam failure mapping has been prepared for the City of Carlsbad, see Map 5.10.1-2: I Failure Inundation/Tsunami and Seiche Map. This map is based on engineering and hydrology stu performled mostly during the 1970's. Since that time, some existing conditions, such as topograi have been modified. Where significant changes in topography or other conditions have occurred s the original studies were performed, the inundation zones were revised to reflect the most curl conditions. The primary zones of inundation reflect water flows from Squires Dam, Lake Calavi Encinitas Creek and the San Marcos Creek drainage. A tsunaimi is a sea wave generated by offshore submarine seismic disturbance such as earthqui landslide or volcanic activity. A seiche is a periodic oscillation in a water body, such as a lagooi lake, and can be caused by tsunamis, earthquakes, submarine landslides, storm winds or baromc disturbances. Whiile Carlsbad is a coastal city with three coastal lagoons, the tsunami and sei hazards are very low. Only small-scale tsunamis and seiche have historically occurred in Carlst The tsunamis and seiche have caused mostly unperceivable water level variations and they have endangered people or propeny.

All development in these areas must be approved through a SUP which requires compliance with the City's Floodplain Management Regulations (Chapter 21.1 18 of the Zoning Ordinance). In addition, General Plan Land Use Element and Public Safety Element policies are intended to avoid locating dwellings or development near natural hazards such as floodway and inundation zones. The source of hazards from dams are of three major types: (1 ) failure of the dam structure during a seismic event; (2) overtopping caused by a landslide into a reservoir; and (3) seiching. The State Department of Water Resources is responsible for the safety of dams in California, other than those federally owned. At present, based on available information, implementation of the updated General Plan will not increase hazards related to dams (R-1). The risk of tsunamis in Southern California is very low and there is not a significant increase in this risk by the implementation of the Carlsbad General Plan. The General Plan Public Safety Element has policies intended to minimize impacts from these types of hazards. 5.10.1.4 Level of Sianificance Adoption and implementation of the General Plan will not result in significant impacts to public health and safety as related to risk of upset. 5.10.1.5 Mitisation Measures Implementation of the updated General Plan will result in no risk of upset impacts and no mitigation is required.

Section 5.10.1, Risk of Upset, is closely re1 to this section because human health and risk of upset are interdependent environmental issues. Fire Hazards The widespread distribution of natural brush vegetation in Carlsbad creates a potential for wild fires. Fire hazards are described in conjunction with fire protection services, Section 5.1 2.5, Protection. The effect of the General Plan on fire hazards is also assessed in Section 5.1 2.5. McClellan-Palomar Airport McClellan-Palomar Airport is located approximately four miles southeast of the Carlsbad Village A This County owned and operated facility is a major general aviation facility for northern San Di County. The San Diego Association of Governments (SANDAG) is responsible for preparing Comprehensive Land Use Plan (CLUP) for the area surrounding the airport. The CLUP designates land around the airport and extending to the east and west of the runway as the Airport Influe Area. This area could experience noise levels exceeding the California State Noise Standards require height restrictions to prevent obstruction of navigable air space. Within the Airport lnflue Area there are also Clear Zones which are areas at either ends of the runway over which aircraft rr pass. Clear Zones are owned by the county and land uses are restricted. Flight Activity Zones located at the east and west ends of the runway and are areas within the Influence Area which intended to be kept free of intensive development and all uses which include assembly of large gro of people (R-1 1. I I Oil Spills The City of Carlsbad could be affected by coastline oil spills although this is unlikely due to the limi tanker traffic adjacent to the coastline. The U.S. Coast Guard has responsibility for clean-up operati in conjunction with the State Lands Commission and the California Department of Fish and Game. - San Diego Gas and Electric (SDG&E) Encina Power Plant on Carlsbad Boulevard is the only busin in Carlsbad that has direct delivery from ocean oil tankers. This facility accepts oil deliveries fr approximately four tankers and three barges annually. Deliveries have lessened over the last dec due to the increased use of natural gas rather than oil. The Coast Guard and the Department of t and Game monitor oil transfer, cleanup operations and annual oil boom deployment exercises. SDG maintains oil transfer emergency response equipment, including a 1 1 O-foot oil spill response ves with containment booms, skimming equipment, oil storage capacity and absorbent materials; moor assistance vessels, divers and safety personnel. This equipment is available to the City of Carlst as well as nearby coastal communities in the event of oil spills affecting their shorelines or lagoo The City, under its Disaster Preparedness Plan, would be responsible for any land operations such traffic control. I - 1 HEALTH, SAFETY, AND NUISANCE FACTORS 5.10.2- FINAL MASTER Environmental fmroact ReRort Electro-Magnetic Fields Electro magnetic fields (EMF) are generated by electrical current passing through wires. High-voltage transmission lines, low-voltage distribution lines, substations, electrical service vaults, and household appliances all generate EMFs. Although there has been a great deal of scientific discussion, it has not been conclusively established whether or not EMFs are harmful to human health (R-2, R-3). Hazardous Materials Approximately seventy-five percent of registered hazardous substances in the City are located at gas stations and auto-related businesses. All gas stations are located on land which is commercially designated on the General Plan. Smaller scale auto service uses such as body shops and repair shops are generally located along State Street. Other small scale uses such as dry cleaners, medicaVdental offices and veterinary clinics utilize and produce extremely small quantities of hazardous materials and waste annually and are also distributed again largely through the City's commercially designated land use areas. The larger-scale use of hazardous materials is well defined in the community, and is restricted primarily to industrially allocated land in business parks surrounding the airport and west of Interstate 5 along Avenida Encinas. The majority of these uses are either related to semi-conductor production, or the biotech industry. Additionally, small scale aviation-related business (which may, for example, store aviation fuel) are also located near the airport. The only industrial business operating on land without an industrial General Plan designation is the South Coast Asphalt Company, located on Haymar Road. This business utilizes quarrying and road surfacing materials. Utilities, such as SDG&E and Encina Water Pollution Control Facility, use some hazardous materials in their operations but they do not directly manufacture or dispose of hazardous materials as their primary purpose. These sites are designated Public Utility on the General Plan and Zoning Map (R-4) (R-15). There are two former waste disposal sites located within the City. The first site is adjacent to the south side of McClellan-Palomar Airport. This site was used for disposal of household waste between 1962 and 1975. No hazardous materials have been identified at the site, and it is currently being closed and capped by the County of San Diego in accordance with Title 14 of the California Code of Regulations. The second site is located in the far northeastern corner of the City. This site was also used for the burning of municipal waste. It has not been operational since 1961 and has since been redeveloped (R-17). There are no known illegal dumps with hazardous matvials within the City of Carlsbad (R-18). Household Hazardous Materials And Waste Household hazardous materials include substances such as, cleaners, paint products, automotive products, hobby products and other toxic substances found around the home. These substances are distributed in substantial quantities throughout the community. In Carlsbad, 97,807 pounds of household hazardous waste were disposed of at collection events in 1992 (R-7). Transoortation Transportation of hazardous materials is overseen by the County of San Diego Department of Health Services. Hazardous Waste must be transported only by registered hazardous waste haulers to state- permitted treatment, storage or disposal facilities.

The City of Carlsbad restricts road transportation of such materials to F arterials, outside riush hours, and requires that the police and fire departments are informed of the t of transfers (R-9). Aaricultural Chermical Residue Agriculitural chemical use in Carlsbad has changed in recent years due to increases in cher regulation and changes of crop types. Certain hazardous chemicals known to be potentially har to public health such as chlorinated hydrocarbons have been restricted. The organic pesticides currently used in agricultural areas in Carlsbad, are generally bio-degradable break down relatively easily into elemental constituents), have short-term decomposition rates, am relatively safe to the general public and the environment. Previously used agricultural chemicals . as DDT and chlorinated hydrocarbons are also bio-degradable; but their rate of decompositia extremely slow, and detectable levels are present in the soil for many years after their applical Varying trace amounts of these materials can probably be found in most of the City's currently previously used agricultural areas and they may pose public health risks, where they are in conceni rations. In addition to pesticides, other chemicals are used in the local agricultural industry such as herbici fungicides, insecticides, and miticides, all of which have varying degrees of toxicity degradation, prevalence in the environment. In the past, to ensure proper application of chemicals, growers were required to file Pesticide Reports with the California Department of Food and Agriculture (DFA) detailing the use of cei Restrictled Materials. Non-restricted chemicals did not require a Use Permit. Recently the State required that all pesticide use now be reported to the Director of Food and Agriculture. Accordin County records, various restricted and non-restricted chemicals are currently being used in agricull areas throughout Carlsbad. The San Diego County Department of Agriculture Weights and Measl and the California Department of Food and Agriculture are responsible for regulating safe applica of these agricultural chemicals. Agricultural chemicals are stored generally in storage facilities at agricultural site, within farm buildings or in greenhouses. I Disaster Preparedness In addition to the regulatory and preventative measures described above, the City has adopted the 1 of Carlslbad Emergency Plan. This plan has been prepared in conjunction with the Unified San Di County Emergency Services Organization (USDCESO) and addresses the City's planned respons extraordinary emergency situations associated with any type of natural disaster, technological incid or State of War emergency. The plan combines flexible disaster response with use of City facili and personnel and agreements for use of facilities in other cities. The City of Carlsbad periodic conducts emergency simulation exercises to maintain the effectiveness of the response organizal and refine the implementation of the plan. 5.10.2.2 The project will have potentially significant impacts if it will: __ Threshold For Determinina Sianificance 1.

The CLUP is a State required long range master plan, updated every five years, intended "to provide for the orderly growth of each public airport and ..... [to1 safeguard the general welfare of the inhabitants within the vicinity of the airport and the public in general" (Section 21675 , Public Utility Code). The CLUP contains building height controls, noise contours and land use controls in this regard. Since the updated General Plan is consistent with the CLUP (as required by State law), significant public health hazards have been precluded. The land uses and policies established by the General Plan are consistent with the CLUP. Because the CLUP is designed to minimize public safety hazards and the General Plan conforms to the CLUP, implementation of the General Plan will not create significant public health hazards related to operation of the airport. Oil Spills As noted above, the Encina SDG&E plant is the only facility in Carlsbad to take delivery of oil from the ocean. No amendments to the "U" (Public Utilities) designation are contemplated which would effect the SDG&E facility. On-shore oil and gas facilities are allowed in the Heavy Commercial - Limited Industrial Zone (CM), the Industrial Zone (M) and the Planned Industrial Zone (PM). However, there are no such uses presently within the City. Factors which could lead to the development of such facilities, such as nearby oil fields or large port facilities, are not present in Carlsbad. There are performance standards within these zones which would ensure that if such development is proposed, that they would be compatible with existing and planned surrounding uses and that they would not constitute a public health, safety or welfare hazard. Additionally, Federal and State regulation of these types of uses would also ensure that they would not result in significantly adverse environmental impacts. Electro Magnetic Fields As noted above under Environmental Setting, there has been much scientific debate on this topic, but it as not been established whether EMFs are harmful to human health or not. The General Plan recommends monitoring research in this field as well as the regulatory proposals of Federal and State health and environmental agencies. Currently, however, it has not been demonstrated that there is a significant environmental impact from EMFs. Hazardous Materials The General Plan will allow for a further 11,735 gross acres of planned industrially designated land. Incrementally, this could result in an increase in the amount of users of hazardous materials. Significant adverse public health impacts from increased hazardous materials use will be precluded by regulatory control. The City of Carlsbad employs a coordinated and cooperative approach between many agencies and regulations. In some instances, the City incorporates other agency's regulations, since they provide an effective means of control. In other cases, the City does not have the prime responsibility to regulate but assists the lead agency in this role. At least sixteen different agencies regulate hazardous materials. The following agencies have major roles in hazardous materials management in San Diego County and Carlsbad: (R-8) (R-14).

The HWMP also contains criteria for determining the location of hazardous waste facilities, however, the final determination of the suitability of a particular location is made by the City of Carlsbad, on a case by case basis, by a siting analysis and environmental review. This also applies to facilities handling hazardous substances in general. Carlsbad's General Plan calls for compliance with this plan as a goal (R-8). The majority of operations handling hazardous substances are located on land with a General Plan designation of Planned Industrial. The industrial section of the Land Use Element requires that industrial development occur with "desirable environmental quality standards" and that industrial land uses be regulated "on the basis of performance standards ..." (R-19). Such policies minimize the potential adverse impacts of hazardous substances on humans. The City's General Plan land use designations and implementing zoning are designed to separate incompatible uses, such as residences and industries. Additionally, the City's zoning ordinance contains development standards which regulate the operation of certain uses including those with hazardous waste or materials. Small scale users and producers of hazardous materials and of hazardous wastes (e.g. body shops, auto repair shops) may also be located in commercially designated and zoned sites. Federal, State, and County authorities regulate the operation of these particular uses as noted above. The General Plan proposes no new waste disposal sites within the City of Carlsbad, and there are no proposed changes in the location of existing potential sites for hazardous material users. Specified hazardous waste disposal and treatment facilities in Carlsbad are subject to a Conditional Use Permit. Prior to approval of such a Conditional Use Permit the City must make findings of compliance with sections of the HWMP. These sections provide siting and operating criteria which aim to protect residents (R-8). Any such hazardous waste facilities would be restricted to industrially zoned land in the City, and after applying the siting criteria only a very limited portion of the City's industrially designated land (around the airport) would be available for locating such uses. In addition, State Law (Section 65850.2 of the Government Codel requires that applicants disclose, upon submittal of an application to the City, whether or not specified hazardous materials will be used in a proposed project. This law also prohibits the City from issuing a certificate of occupancy where a project, if required by law, does not comply with applicable sections of the Health and Safety Code. Household Hazardous Materials The purpose of the San Diego County's household hazardous waste program is to educate residents about the hazards associated with the use, storage and improper disposal of household chemicals and to provide convenient disposal alternatives for household hazardous wastes, including collection events. Such education and collection events are coordinated in and around the City of Carlsbad. The City adopted the Household Hazardous Waste Element (1 991 ) which embraces the objectives of the County program. In addition to education and periodic collection services, the City also offers a permanent facility, to collect automotive waste (R-12). While implementation of the General Plan will increase residential uses and related household hazardous materials, continuation of the County program will minimize the associated public safety impact.

Remedial measures will be necessary in those locations w human health may be significantly affected by current or past use of agricultural chemicals. Restricted chemicals used in Carlsbad prior to the establishment of current Federal and I regulations could pose a significant health risk if soil levels exceed allowable concentrations. County of San Diego Department of Health Services produces a list of hazardous agricul substances together and application rates. None of the Chemicals listed on this table are currenl use in the City, but may have been used previously. Due to the differing decomposition rates tl chemicals are likely to be found in the soil in agricultural locations throughout Carlsbad. The d application of chemicals, according to Federal regulations and State regulations, over a large i would result in extremely low soil contamination because chemicals are absorbed more readily diffuse fairly rapidly into the soil. In some handling or storage areas, however, soil contamination c exist because of the larger quantities and higher concentrations involved and potential for accidc spills or mishandling. Remedial measures should be used where soil testing detects these hazarc chemicals at levels which would have significantly adverse effects on human health. It is difficult to identify potentially contaminated areas in Carlsbad due to lack of documentation. F to the late 1970s-early 1980s, records such as Pesticide Use Reports were not required to be kep growers. Therefore, with this lack of information it must be assumed that soil contamination may I- occurred in all agricultural areas due to the application, handling, storage, or dumping of potent toxic or restricted agricultural chemicals. Presently, no illegal dumping sites are known. Prior to fu developiment, soil testing should occur. The bottom of natural canyons, mixing and loading ar illegal trash dump sites, or near piped water sources, such as abandoned irrigation lines are pos: soil contamination sites. These sites could be identified from old aerial photographs which st former agricultural structures or chemical handling, storage facilities. Land Use lncomeatibilities As development proceeds within the City, conflicts associated with spraying, irrigation runoff, odors may arise between adjacent agricultural operations and residential uses. Adequate buffer design measures, or possible modification of certain agricultural practices, should be used to pro future residential development areas within Carlsbad from possible health affects. Disaster Preparedness - The buildout of the updated General Plan update will add approximately 25,389 new residential ui and 45.6 million square feet of non-residential uses. The disaster preparedness plan is designed tc flexible enough to respond to any type of natural disaster. Implementation of the plan is designec be refined after periodic emergency simulation exercises and based on this it should automaticall) adjusted to accommodate the increased growth of the City and preclude any future significar adverse effects on public health. 5.10.2.4 - Level of Sionificance Human Health will potentially be impacted by the development of planned residential uses on si Contaminated by agricultural chemicals.

The aesthetic quality of the City is characterized by many components that creat aesthetically pleasing mixture of natural and urban landforms. These components include a na environment of diverse landforms, rock outcrops, plants and animal resources, natural colors and I and panoramic piiblic views of the horizon, foothills, lagoons, and the Pacific Ocean. The environment incluldes historic buildings, fields of colorful flowers during certain seasons of the ! landscaping, signage, and works of art. There irj no dominant architectural theme throughout the City, however, there is a concentratic older Victorian style structures in the northwestern portion of the City and many Spanish and Web Ranch :style buildings in the southeastern portion of the City. The industrial corridor in the ce portion of the City, located around the airport, is characterized by large industrial parks nestled the hills with a variety of glass/concrete office, manufacturing, and warehouse buildings. In 1988, the City prepared Scenic Corridor Guidelines to identify roadways and transportation ro within the City of Caflsbad to be designated as scenic corridors, and to suggest methods to pres and enhance the character of those corridors (See Map 5.1 1-1 : Scenic Corridor Location N Transportation routes with potential corridor status are identified and described in Table 5.1 1-1 : Scl Corridors. Currently, El Carnino Real is the only designated scenic roadway within the City for wl a set of development standards have been adopted. I 5.1 1.2 - Basis for Deterrninina Sianificance The project will have potentially significant impacts if it will: 1. Block public view corridors; 2. 3. Destroy prominent visual characteristics of the community; or Conflict with the community's design and development values (i.e. land use character) of subject area and surrounding areas. - 5.1 1.3 - Environmental lmoacts Through implementation of the updated Carlsbad General Plan, additional development in the forn cut and fill slopes, roads, buildings, sound attenuation walls, and landscaping will occur through the City. Conversion of vacant undeveloped land to urban uses will result in changes to the exisl topography and the removal of existing trees and native vegetation. Vacant hills, ridges, canyons, property adjacent to lagoons may be graded and developed with roads, residential, commercial industrial structures. Structures may be developed along existing rural roadways, thus changing rural character of some areas of the City. - e AESTHETICS 5.1 1- CITY OF CARLSBAD SCENIC CORRIDORS _____-_------ \.___----, oooo Community Theme Corridas -------- Community Corriclars *0*0*4* Natural Open Space Corridors *---- Railroad Corridor swce:scenicconidorc;uidehes,cityofcarlsbad MAP 5.11-1 4 5.11-2 FINAL MAS Environmental lmrract Re CITY OF CARLSBAD 1 I 1 I I I 1 1 1 I 1 1 I 1 I I I 1 AESTHETICS 5.1 1. 1 TABLE 5.1 1-1 SCENIC CORRIDORS DESCRIPTION POTENTIAL IMPACTS Theme Corridors - Lagoon, and hillside views Collector street with Batiquitos Lagoon and hillside commercial development along the north and SOU Hedionda Lagoon Additional residential development in the north/so along the north shore of Batiquitos Lagoon and of.

As the City continues to urbanize, development will also occur in these coastal areas. Urban development along the coast and in close proximity to the City's lagoons may create a potential for visual impacts to significant public viewsheds. Adherence to coastal policies concerning public view preservation and public access contained in the City's Local Coastal Program will help reduce any negative visual aesthetic impacts created by future physical development. In addition, development along the City's scenic corridors may include graded cut or fill slopes, ornamental landscaping, and the construction of various types of buildings and site improvements, including parking areas and driveways. Potential impacts to the City's scenic corridors are summarized in Table 5.1 1-1. Although existing landforms would be altered and the rural and agricultural character of some areas within the City would be affected, the changes in aesthetic character are not considered a significant visual impact. Potential impacts will be precluded by fully implementing all relevant General Plan policy guidelines and action programs, adopted City ordinances, and other planning programs. This includes consistency and compliance with the following policies, guidelines, ordinances, and programs: Carlsbad Municipal Code Title 21.53 and California Environmental Quality Act - Preservation of steep slopes (40% or greater) and other environmentally constrained areas (i.e wetlands, and floodways). CITY OF CARLSBAD Local Coastal Program policies (i.e. Mello II Environmental Resource Overlay Zone) - Preservation of sensitive environmental resources and slopes greater than 25% and public view preservation).

The district boundaries are sh in Map 5.1 2.2-1 : City of Carlsbad Water Districts. The three water districts purchase imported water from the San Diego County Water Authority in turn relies upon the Metropolitan Water District for its supplies. Water supplies to all three dist are imported entirely from outside of the San Diego Region (R-1). Imported Water Sources Supplie:; to Carlsbad, as well as the Southern California region, are imported via the Colorado River California Aqueducts. The California Aqueduct delivers State Water Project (SWP) water from sev sources in Central and Northern California, including Oroville and San Luis Dam. Metropolita contracted for delivery of 2,011,500 acre feet of this water per year (AFY), about forty-eight perc of the rota1 planned project yield. The SWP was conceived to add additional water storage transfer facilities a:; increased deliveries occur over time, but no such reservoirs have been consttuc since completion of the Aqueduct in the early 1970s. At the same time, Metropolitan's need for w has been increasing. The SWP is currently providing a dependable supply of about one-half of 1 contracted amount (R-I 1.

In return for implementing a water conservation program with Imperial lrriga District, the largest user of Colorado River water, the MWD could obtain an additional 106,110 I upon full implementation of the program. The ability to divert additional water will also be dependc however, on hydrologic conditions along the River and demands from other users (R-1 I. The California Aqueduct and Colorado Aqueduct converge near Lake Perris in Riverside County wt the water continues south as the First and Second San Diego Aqueducts (R-3). Carlsbad acces most of its water from the Palomar Road Connection which extends to the Second Aqueduct. The Agency Pipeline and South Aqueduct connections access the remaining water supply. Approximai 44.5 million gallons (1 39 AF) of water is stored in the CMWD's eleven tank reservoirs and 196 mill gallons (600 AF) of water is stored at Squires I Reservoir (R-1,5). The Squires Dam Reserv however, is not corisidered a usable potable water source until it is lined and covered. These reservc provide a 15-day emergency supply.

Most of the major river systems in Sou California have been developed into a comprehensive system of flood control channels, dams percolation ponds for artificially recharging groundwater. A study by the Los Angeles Cc Departrment of Public Works has shown that ninety percent of rainfall and runoff in the Coui captured before rleaching the ocean. The ChdWD's only potential for obtaining groundwater is through their water rights to the San Lui: River Basin. Refer to the Section 5.2, Hydrology, of this report for further details. There are eighteen major reservoirs in Southern California, fourteen of which are operated by Diego County agencies. The San Diego region supplies a dependable yield of 50,000 AFY; how in drought years this amount may be decreased in half. There are no major reservoirs withii CMWD's service area or in any neighboring jurisdiction. The Olivenhain Municipal Water District the San Diego County Water Authority are, however, studying the feasibility of constructin1 emergency storage reservoir in the Mt. Israel area (R-1). Reclaimed Water Water reclamation involves treating wastewater for beneficial uses other than human consump its transportation to the place of use, and its actual use. By installing and extending reclaimed v. systems, demand for imported potable water sources will decrease. Like other water distric Southern California, the CMWD is currently utilizing financial assistance from the MWD to cons1 a complete reclairrred water system. Projections indicate that by the year 201 0, total use of reclai water in San Dieglo County will reach 100,000 AN (R-1 1. By the year 201 2, total use of reclai water in Carlsbad is expected to reach 1 1,480 AFY (R-2). The City has recently adopted a Water Reclamation Master Plan to provide the City with a feasible to serve the reclaimed water markets identified in the study. Potential "Reclaimed Water Mark include public and private irrigation uses (e.g. golf courses, crops, nurseries, landscaped arc industrialkommercial uses, and ecological uses (e.g. Lagoon/stream enhancement, groundw recharge). The Master Plan is proposed in five phases, with Phase V to be completed in 2012 (F The Aviara Development, as part of Phase I, has already installed an extensive reclaimed water sys used to irrigate golf courses, slopes, greenbelts, and common areas (R-1 1.

Sewer service sysi consist of major trunk sewers, pump stations, and forcemains which collect and transmit wastew to wastewater treatment facilities. Each sewer district has prepared sewer master plans or st1 which evaluate the adequacy of existing sewer conveyance systems and wastewater treat1 facilities, project future demand, and determine improvements required to provide adequate sc treatment capacity for future development (R-1 , 2, 3). Citv of Carlsbad Sewer Svstem The Carlsbad Sewer District serves the majority of Carlsbad. There are five sewage drainage ba with four existing interceptor sewers transporting wastewater to the Encina Water Pollution Coi Facility (EWPCFI for treatment within the Carlsbad Sewer District. The Carlsbad Sewer District sh ownership of the interceptor sewers with the other participating sewer districts. Vallecit os Water District The Vallecitos Waiter District provides sewer service to approximately 550 acres of southeas Carisbad. The conveyance system within VWD is divided into two principal drainage basins: central basin that is tributary to EWPCF via the existing land outfall and the Meadowlark basin th, tributaqr to Meadowlark Water Reclamation Facility (MWRF). Leucadia Countv Water District The Leucadia County Water District provides sewer service to the majority of southeastern Carlsl The conveyance system within LCWD is divided into 11 sewage drainage basins (four within the of Carlsbad), which transmit wastewater to either the Gafner Wastewater Treatment Plant or EW for treatment. Wastewater Treatment Facilities The majority of the wastewater generated in Carlsbad is conveyed through major interceptor sew to the Ericina Water Pollution Control Facility for treatment. The Encina Water Pollution Control Fac is a regional wastewater treatment plant currently providing 36 million gallons per day (mgd wastewater treatment capacity to the cities of Carlsbad and Vista, the Buena Sanitation District, Vallecitos Water District, the Leucadia County Water District, and the Encinitas Sanitary District. SI the EWPCF is located in the City of Carlsbad, major interceptor sewers transport wastewater f other districts through the City of Carlsbad to the EWPCF for treatment.

Vallecitos Water District an Leucadia County Water District also operate satellite wastewater treatment facilities within the of Carlsbad and while not operational, the Carlsbad Sewer District also holds title to the sal Calavera Hills Wastewater Treatment Plant. The LCWD Gafner Plant and VWD Meadowlark V Reclamation Facility provide wastewater treatment capacity to portions of southern Carlsbad (see 5.1 2.3-1 : Sewer Districts). The Encina Water Pollution Control Facility provides approximately 24 mgd of secondary wastev treatment capacity to all three sewer districts serving Carlsbad. Current demand for waste\ treatment capacity by the three districts at the EWPCF is approximately 13 mgd. The Mead01 Water Reclamation Facility provides another 2 mgd of wastewater treatment capacity to the Valle Water District, and the Gafner Wastewater Treatment Plant provides another .75 mgd to the Leu( County Water District. When operational, the Calavera Hills Wastewater Treatment Plant will prc 1.2 mgd of additional wastewater treatment capacity.

A permit for expansion of the landfill was approved by the California Integrated Waste Management Board in March 1993. The landfill will be permitted to expand its capacity to include approximately eight million additional cubic yards. The life of the landfill would be extended a minimum of five to eight years. This projection varies due to a potential generation reduction which may occur as a result of increased recycling of solid waste (R-4). Three alternative sites have been identified for a potential new landfill in northern San Diego County and are being considered in ongoing environmental and engineering studies. The three locations are described as: Blue Canyon: Aspen Road: Gregory Cyn: southwest of State Route 79, about 7 miles northwest of Warner Springs west of 1-1 5 and about 4 miles northeast of Fallbrook 3 miles east of 1-1 5 and 2 miles southwest of Pala, opening to the San Luis Rey River valley. Sufficient landfill capacity to accommodate projected growth is an issue the City must address as the General Plan evolves. The City adopted its Source Reduction and Recycling Element (SRRE) in the Fall of 1992, pursuant to State laws. Implementation of the SRRE programs are necessary to achieve the State-mandated 25 percent diversion goal by 1995 and the 50 percent diversion goal by 2000. If the SRRE goals are achieved, projected solid waste generated by General Plan buildout development will be approximately the same as current levels. 5.12.4.4 Level of Sianificance Based on the above analysis, impacts to solid waste will be significant, but mitigable. The existing policies and proposed mitigation lessen the impacts to the greatest extent possible given the regional and cumulative nature of solid waste impacts. 5.1 2.4.5 Mitiaation Measure 1.

The Fire Department has a total c employees and maintains six fire stations (see Map 5.12.5-1 I. In addition to providing fire protec the Firc Department provides basic and advanced emergency medical services through the use o engines and paramedic ambulances. Twenty-one firefighters are certified as paramedics an firefighters are certified to the Emergency Medical Technician/Fire Service Level as required b? State of California. Table 5.1 2.5-1 : Fire Protection Equipment and Personnel, lists the personne equipment at each of the six stations. The Fire Department maintains six fire stations strategically dispersed throughout the City. locatiori of the fire stations are dictated by Carlsbad's Growth Management Plan which t- performance standard that requires additional fire stations whenever there are more than 1 dwellinlg units located outside a five minute road-response time from an existing station. The City was last surveyed by the Insurance Services Office (IS01 in 1992 and received a Cla rating. Based upon the IS0 rating system of Class 1 through 10, with Class 1 being the highest ra the Carlsbad Fire Department offers adequate fire and emergency medical service. The Departrnent requiires a minimum flow of water for fire protection in accordance with the ado Uniform Fire Code and the IS0 standards of 1,000-1,500 gallons per minute for single-family resid€ land uses and 1,500 - 5,000 gallons per minute for multi-family, commercial, and industrial land i There are currently no water flow deficiencies within the City. The Firt! Department has signed Automatic Aid Agreements with all surrounding communities for a support when additional fire fighting resources are needed. The City is also part of the San C County and State of California Master Mutual Aid Agreement and maintains a separate agreement the Cat tfornia Department of Forestry. The City is considered a medium fire hazard area for wildland fires which could threaten urban undeveloped areas due to the large areas of natural vegetation along the City's eastern border within ithe City Limits. There are many inaccessible brush-covered canyons and hillsides in the which add to the wildland fire hazard. The City of Carlsbad has large areas of natural vegetation some of which are classified as "high species" by the Ci*ty's Landscape Manual (e.g., Sage, California Sagebrush, Buckwheat, etc.1. In n areas there are inaccessible steep, brush-covered canyons and hillsides which add to the C wildland fire hazard. During times of hot dry weather and Santa Ana winds, the risk of brush fir high. lhe City uses outside mutual-aid fire fighting help to control such large-scale fires. Brush may pose a threal directly to both endangered species and habitat (e.g., Coastal Sage Scrub) ar buildings and humans which are close to areas of natural vegetation. Approximately 80 percer structural fires in Carisbad are in single family residences usually involving common household cont such as furnishings, wood and plastics (R-15). 1 - 1 I - 1 UTILITIES & PUBLIC SERVICES 5.1 2.5 7 CITY OF CARLSBAD FIRE STATIONS Existing 0 Proposed souce:cityofcarlsbad 5.12.5-2 MAP 5.12.5-1 d I I 1 1 1 ' ' I ' 1 ' I FIRE PROTECTION EQUIPMENT AND PERSONNEL -- ON-DUTY PERSONNEL FlREFl G HTlNG EQUl PMENT Station #1 3 Firefighters 1 Reserve Mobile Intensive Care Unit 2 Paramedic/ 1 Mobile Intensive Care Unit firefighters 1 Reserve Engine 1 Engine 3 Firefighters 2 Paramedic/ 1 Engine firefighters 1 Mobile Intensive Care Unit 3 Firefighters 1 Brush Engine 1 rtation #2 rtation #3 1 Engine ptation #4 1 Engine 3 Firefighters 1 Rescue Truck rtation #5 1 Field Supervisor 1 Brush Engine 1 Engine rtation #6 3 Firefighters 1 Engine Source: Fire Department Records, City of Carlsbad. 3 Firefighters 1 Reserve Engine - FINAL MASTER Environmental ImRact Remrt 5.1 2.5.3 Environmental ImDacts Implementation of the updated Carlsbad General Plan will result in additional residential, commercial and industrial development. This will increase the demand for fire protection services and will result in the need for additional manpower and equipment to serve Citywide demands. Currently fire protection services are adequate to meet existing demands. The Growth Management performance standard can be maintained with the six existing fire stations through buildout of the City (R-1). As population increases, the demand for emergency services will also increase. The fire stations are managed and planned to ensure that additional personnel and equipment will be added when necessary (R-2). As the City grows fire protection services will be added to adequately serve the new development. As development occurs as a result of buildout of the General Plan there will be an increase in development near areas of native vegetation (for instance, development next to preserved habitat areas or open space). This may increase the risk of wildfires. Wildfire prevention techniques are implemented through the City's Landscape Manual which requires on and offsite fire protection measures such as fire control planting, low water use and low fuel species; fire suppression, including removal and selective pruning of fuel species; and long term maintenance of fire protection areas (R- 10). All future projects must comply with the Landscape Manual to minimize fire hazards. In addition, a Fire Suppression Plan is required when a proposed development project contains or is bounded by hazardous native vegetation as determined by the Fire Chief. The required Fire Plan includes landscape treatment and clearing designed to mitigate fire dangers to structures located adjacent to natural vegetation areas. Building permits are also reviewed by the Fire Department for compliance with the Uniform Fire Code. The Fire Department has a weed abatement program which begins in April each year and is designed to reduce fire hazards by clearing weedy type vegetation around structures and on vacant lots. 5.1 2.5.4 Level of Sisnificance While an adequate number of fire stations have been developed in the City, the increased fire hazard will require additional staff and personnel. Based on this analysis, impacts to fire protection resulting from the proposed update to the Carlsbad General Plan will be significant but can be mitigated to an insignificant level. 5.1 2.5.5 Mitisation Measures The following measures are required to mitigate impacts to fire protection services: CITY OF CARBSBAD 1. Require compliance with the adopted public facility performance standard for fire services to ensure that adequate public facilities are provided prior to or concurrent with development as follows: No more than 1,500 dwelling units outside of a five-minute response time.

These are supplemented by a problem-solving approach used by officers to help solve community problems which often enlists the help of other City departments as well as County and State agencies. In addition, the Police Department reviews development projects and provides recommendations on, street access, safety, security measures, and the utilization of adequate lighting, and buildingktreet addresses. 5.1 2.6.2 The project will have potentially significant impacts if it will result in conflicts with adopted service standards for law enforcement services. 5.1 2.6.3 Environmental lmoacts Implementation of the proposed update to the Carlsbad General Plan will result in additional residential, commercial and industrial development. This will increase the demand for police protection services in newly developing areas and will result in the need for additional personnel and equipment to serve Citywide demands. Police facilities are included under City Administrative Facilities in Carlsbad's Growth Management Plan and funds for these administrative facilities are generated by public facility fees (PFF). PFFs are paid by developers before building permits are issued. Funding for additional police services required by new development will be allocated from the City's General Fund. Currently, the Police Department meets its six minute response time threshold standard and no problems are expected in meeting the additional demand for police protection represented by an increased population created by future growth (R-1 1. 5.12.6.4 Level of Sianificance While an adequate number of police stations, manpower, and equipment have been developed in the City, increased crime and traffic hazards will require additional staff and personnel. Based on this analysis, impacts to law enforcement resulting from the proposed update to the Carlsbad General Plan will be significant but can be mitigated to a level of less than significant. 5.12.6.5 Mitiaation Measures The following measures are required to mitigate impacts to law enforcement services: CITY OF CARLSBAD Basis for Determinina Sianificance - 1.

Specifically, soils are assessed relative to a Capability Class rating (Class I to VIII) and a Storie Index rating (0 to 100). Soils with a Capability Class of I or II and a Storie Index rating of 79 or higher are considered prime agricultural soils by the Soils Conservation Service (SCSI. While some areas are considered prime farmland by the Department of Conservation, they may lack the physical soil properties (as indicated by Capability Class and Storie lndes ratings) to be considered prime soils by the SCS. For environmental review under CEQA, the City of Carlsbad typically uses the SCS criteria for prime agricultural soils when determining impacts to agricultural lands. Map 5.1 3-2 shows that the Carlsbad Ranch area (south of Agua Hedionda Lagoon and east of the 1-5 freeway), contains prime farmland pursuant to the Department of Conservation criteria. However, the soils involved, Carlsbad gravelly loamy sand SbBI and Marina loamy coarse sand (MIC), are not considered prime agricultural soils according x the SCS criteria. The soils do not have a Capability Class of I or I1 and the Storie Index rating varies between 23 and 54. Some agricultural land in Carlsbad is subject to a Williamson Act Land Conservation contract as allowed by the State Legislature under the California Land Conservation Act of 1965, The Williamson Act. The Williamson Act permits local jurisdictions to enter into contracts with landowners. The contract restricts the use of the land to agricultural, recreational, or open space uses and limits the land's potential for subdivision or development. In exchange, the property owner receives a reduction in property tax. The term of the contracts is typically ten years and are renewed automatically each year. The amount of the tax reduction is based on the difference between the agricultural value of the property and its market value. Should the property owner desire not to renew the contract, a Notice of Non-Renewal must be submitted 90 days prior to the renewal date. The contract will then expire ten years after the submittal of the Notice of Non-Renewal. Approximately 331 acres on the Carlsbad Ranch property in the City of Carlsbad are subject to a Williamson Act Land Conservation Contract. Typical crops grown on these preserve areas include ornamental flowers, ranunculus bulbs, tomatoes and strawberries. The Williamson land contract defines certain restrictions on development of the property for a period of ten and fifteen years. A Notice of Non-Renewal for all 331 acres in Carlsbad Ranch was filed by the property owner and recorded by the City Clerk on November 4, 1991. Approximately 279 acres of the site are subject to the Williamson Act and will remain as an agricultural preserve until January 1, 2002. The remaining 52 acres contain flower fields and are under a 15 year contract prohibiting development until 2007. The Carlsbad Ranch Specific Plan was approved by the City Council on March 16, 1993. The Plan allows a mixture of non-residential land uses on the 423 acre project site. Proposed land uses for the site include office, research and development, related IiGht manufacturing, travel-service commercial, retail, hotel, driving range, agriculture open space areas and potentially, a vocational school campus. The areas under a Land Conservation Contract will be subject to a specific plan amendment and corresponding environmental review prior to any conversion to non-agricultural land uses. 5.1 3.2 MineraVEnergy Resources The project will have potentially significant impacts if it will: 1.

The remaining mineral resources present in the northeastern part of the City are planned to be extracted in the future and urban development has been identified by the General as a preferred use (of these lands. Agricultural Lands Buildout of the updated General Plan may result in the conversion of farmland to urban uses. 01 land currently farmed in the City of Carlsbad, only a limited amount of that land constitutes area prime agricultural soils. Agriculture as an industry is dynamic, and agriculture in Carlsbad as we throughout San Diego County is subject to a number of variables including continually chan markets, variations in crop specializations, urbanization, rising water costs and availability, and diff competition from loreign markets and other U.S. producers (R-1). Through implementation of updated General Plan, the City of Carlsbad will be implementing various policies, goals and objecl designed to lessen the adverse impacts of these variables on agriculture in the area. However, future of agriculture in Carlsbad will be a balance of financial, water supply, and regulatory facl The continuation of agriculture will also depend to a large extent on the ability of farmers to carve a niche !in the markets for relatively higher value crops, while maintaining maximum flexibility of crop mix to meet c:hanging market conditions (R-1). Portions of some properties currently utilized for agricultural purposes have been designated as ( space on the Land Use Map, and are therefore protected as long-term open space. These prope which have a General Plan Open Space designation are more likely to retain agricultural uses sincf land does not represent greater economic value since only mineral and temporary development 1 are allovved in open space areas. The City's Local Coastal Programs' (LCP) policies address the i of premature conversion of agricultural lands to urban uses by establishing programs which re( mitigation for agricultural conversion. LCP policies also provide financial assistance to farmers thrc cash programs. However, buildout according to the General Plan will affect Prime Farmland as def by the State Department of Conservation. The Prime Farmland areas in Carlsbad are not under an ( space designation in the General Plan and they could consequently be converted to urban uses. largest area of Prim Farmland is the Carlsbad Ranch project area.

If development is proposed for one of these areas, a specific study pursuant to CEQA shall be conducted to determine if prime agricultural soils occur pursuant to the Soils Conservation Service criteria. If prime agricultural soils occur, potential impacts will either be avoided or mitigated. General Plan implementation will not impact a Williamson Act Land Conservation Contract in Carlsbad. Carlsbad Ranch is the only site in Carlsbad that is subject to a Land Conservation Contract. Development plans were approved in March 1993 and the site will be developed regardless of the implementation of the updated General Plan. 5.13.4 Level of Sianificance Mineral Resources Based on the above analysis, impacts to mineral resources from implementation of the Carlsbad General Plan will not be significant. Agricultural Lands Based on the above analysis, impacts to agricultural lands and prime agricultural soils from implementation of the Carlsbad General Plan will be significant.

Approximately 6,000 dwelling units have been approved to date and have the potential to be constructed at any time. The 17,424 acres of currently vacant land, (70 percent of the total City acreage), will not be urbanized if the No Project alternative is implemented. Most of the vacant land within the C. boundarie- 2xists in the eastern portions of the City. The eastern areas will remain vacant and the intensity of development in the western areas will not change. This alternative will preclude development of several properties where development is presently allowed. The City's currently adopted General Plan calls for the addition of 25,389 dwelling units for a total of 52,638 dwelling units at buildout and for the addition of 45.6 million square feet of non-residential floor area for a total of 58.3 million square feet at buildout. This development will accommodate a future City population of approximately 125,800 persons. Under the No Project alternative, none of the planned development will occur. The development and population growth projected for Carlsbad will be displaced to the surrounding areas. Implementation of the No Project alternative will reduce most of the environmental impacts associated with implementation of the updated General Plan, including the significant and unmitigable impact to air quality. As described in the next paragraph, circulation impacts will result from regional traffic under the No Project alternative. In addition, implementation of the No Project alternative will cause the growth rates for the surrounding jurisdictions to exceed growth projections and unanticipated environmental impacts may occur. Surrounding jurisdictions may experience population growth that exceeds anticipated levels and the housing stock, including affordable housing, may be inadequate to accommodate the greater demand. In addition, the demand for public utilities and services may exceed the capacity of existing and planned facilities in surrounding areas. The pressure may increase in surrounding cities to develop land with geological constraints and sensitive biological resources and cultural resources. Farmland may be converted at a faster rate due to displaced development and population growth. Conclusion While implementation of the No Project alternative will eliminate the environmental impacts associated with the proposed General Plan, the No Project alternative will result in environmental impacts to the surrounding area. The No Project alternative is not considered feasible. Because no further development will occur in Carlsbad, the City will not be able to comply with State affordable housing regulations. In addition, tax revenue will not increase under this alternative and the City will have no means to finance new infrastructure required to accommodate the impact of regional growth. In particular, the City will lack sufficient revenue to improve the circulation system to accommodate the projected increase in regional traffic. As a result, traffic will exceed acceptable service levels on regional circulation routes. Implementation of the No Project alternative will prohibit property owners in Carlsbad from developing their land and may represent a legal "taking without compensation". 6.2 Existina General Plan Under this alternative, the updated General Plan will not be adopted or implemented and the City will continue to implement the Existing General Plan. In 1985, the Circulation, Housing, and Land Use Elements of the Existing General Plan were updated and the Arts and Historic Preservation Elements were added. Recent changes include revisions to the Parks and Recreation, Housing, and Open Space and Conservation Elements.

Several of the land use designation names in the Existing General Plan are different those used in the updated General Plan but the type and intensity of development are the same. Existing General Plan has 1,500 less acres of designated open space. The environmental impacts resulting from implementation of the Existing General Plan alternativf be mort? substantial than the impacts resulting from implementation of the proposed General Plan. proposed General Plan contains new and modified policies to strengthen the protection of sen! environmental resources. For example, the proposed General Plan contains programs and PO requirin 9 involvement in regional conservation planning efforts and implementation of the City's Hz Management Plan and Open Space and Conservation Resource Management Plan. Implementatic the habitat management efforts identified in the proposed General Plan will better mitgate impac biological resources than the programs identified in the Existing General Plan. The circuL improvements identified in the proposed General Plan will accommodate projected traffic levels maintain acceptable levels of service better than the circulation improvements found in the Exi General Plan. The proposed General Plan also contains a program to protect future residential from residual agricultural chemicals found in soil. This alternative will result in significant cumul air quality and circulation impacts which cannot be mitigated to a level of less than significant. T cumulative impacts are due to regional through traffic and air quality problems. The City ha jurisdicrional contron over regional through traffic and therefore will be unable to reduce the cumul circulation impact to less than significant. The cumulative air quality impact, however, may be red in future years as iregional air quality management plans are implemented and regional pollutant I( are reduced to meet state and federal standards. Conclusion The Existing General Plan alternative is not environmentally superior to the proposed General f Implemsntation of this alternative will result in more substantial environmental impacts implementation of the proposed General Plan. 6.3 Decreased Residential DeveloDment The Decreased Residential Development alternative is the same as the proposed General Plan but 1 acres OF land designated for residential uses will not be developed. Development of this land m: constrained by the predominance of coastal sage scrub habitat and associated sensitive animal plant species (inclluding the recently federally listed California gnatcatcher). A maximum of 7 dwelling units could be developed on this potentially constrained acreage. Under this alternative, t dwelling units will not be constructed and the total number of dwelling units to be developed city- will be ireduced from 52,638 units to 45,485 units. Due to the increaised open space acreage and the reduction in dwelling units, the environm impacts, of the Decreased Residential alternative will be somewhat less substantial than the imy of the proposed General Plan. Hydrology The Decreased Residential Development alternative will result in less impervious surface area thar proposed General Plan. Water absorption rates consequently will not decrease and runoff rates not increase to the same extent. Non-point source water pollutant levels may be somewhat less the pollutant levels resulting from buildout of the proposed General Plan. The geographic exter C ALTERNATIVES 6.( 1 - FINAL MASTER Environmental 1mDact ReDort CITY OF CARLSBAD new drainage facilities will be reduced under this alternative. While the hydrology impacts will be less substantial than the hydrology impacts of the proposed General Plan, the hydrology impacts will be significant and mitigation will be required. Air Quality Implementation of the Decreased Residential Development alternative will result in less construction activity in Carlsbad and less construction-related emissions than implementation of the proposed General Plan. Traffic volumes at buildout will be less due to the reduced number of dwelling units. As a result, the long-term emissions will be somewhat less under this.alternative than under the proposed General Plan. Cumulative local and regional air quality impacts will be significant because Carlsbad is located in an air basin where state and federal pollutant standards are exceeded. The City must implement a number of measures to reduce emissions but impacts will remain significant. The cumulative air quality impacts, however, may be reduced in future years as regional air quality management plans are implemented and regional pollutant levels are reduced to meet state and federal standards. Biological Resources Due to the increased open space acreage under the Decreased Residential alternative, impacts to biological resources will be less substantial than under the proposed General Plan. Significant acreage of natural habitat will still be lost in other parts of the City and the resulting impact to biological resources will be significant and require mitigation. This alternative, nevertheless, will result in the protection of 1,345 acres of additional coastal sage scrub habitat and California gnatcatchers living therein. Population/Housing Based on an average household size of 2.47 persons per dwelling unit, implementation of the Decreased Residential alternative will reduce the projected buildout population by 17,668 persons from 125,837 persons to 108,169 persons. The overall population increase will still be significant and will require mitigation. Because residential development will be reduced under this alternative in the long-term, the City may not be able to fully comply with State affordable housing requirements. Regional and fair share housing requirements may not be met under this alternative. As a result, the population/housing impact of the Decreased Residential alternative is considered more substantial than the impact of the proposed General Plan. - Circulation Due to the lower number of dwelling units, the traffic generated by this alternative will be somewhat less than the traffic generated by the proposed General Plan. Cumulative circulation impacts from local and regional through traffic will be significant. The City has no jurisdictional control over regional traffic and therefore will be unable to reduce the cumulative circulation impacts to less than significant. Noise Because the Decreased Residential alternative will result in less traffic than the proposed General Plan, noise related to traffic will be somewhat reduced. The resulting noise impact of this alternative, however, will still be significant and will require mitigation. 6.0-6 ALTERNATIVES FINAL MAS1 ' CITY OF CARLSBAD Environmental Impact Reg I Aesthelics The aesthetic impacts of the Decreased Residential alternative will be less substantial than the imp of the proposed General Plan. An additional 1,345 acres will be designated as Open Space and n natural landscape in the City will be maintained. Prevailing visual quality standards indicate that nal landscaple has more aesthetic quality than urban landscapes. Nevertheless, a large amount of c space will still be converted to urban uses under this alternative and the resulting aesthetic impact be significant and will require mitigation. Utilities and Public Services Due to the reduced number of dwelling units allowed by this alternative, the demand for utilities public services will be somewhat reduced. However, the impact to utilities and public services will be significant and will require mitigation. Other Environmental Impacts Impacts to other environmental issue areas under the Decreased Residential Development alterna will be similar to the impacts resulting from the proposed General Plan. Conclusion Based on the above discussion, the Decreased Residential Development alternative is considt environmentally superior to the proposed General Plan. While the resulting impacts will be I substantial than the impacts of the proposed General Plan, (with the exception of population/hou! impacts), the resulting environmental impacts will still be significant and will require mitigat Cumulative impacts to air quality and circulation will still be significant and unavoidable under alternative. The Decreased Residential Development alternative is not feasible. Because residential developrr will be reduced under this alternative, the City may not be able to fully comply with State afford; housing requirements in the long-term. In addition, less tax revenue will be generated under alternative and the City will have reduced means to finance new infrastructure required accommodate the impact of local and regional growth. Implementation of the Reduced Resider Development alternauive will prohibit some property owners in Carlsbad from developing their land l may represent a legal "taking" of some properties. Regardless of whether this alternativc implemented, development of some planned residentialareas containing coastal sage scrub may precluded by the federal listing of the California gnatcatcher. 6.4 jlensitv Transfer The proposed General Plan Land Use Element provides for density and development right transfer instances where a property owner is preserving open space in excess of normal City requiremei Under the Density Transfer alternative, the density transfer provision of the proposed Land Use Elerr will be revised to state that density and development right transfers to areas adjacent to m transportation corridors, public transportation facilities, and employment centers will be considerel instances where a property owner is preserving open space in excess of normal City requiremer This revision will allow the City to consider density and development right transfers where propc owners are forced to preserve California gnatcatcher habitat, (i.e. coastal sage scrub), pursuant to 1 1 1 I 1 I I 1 I I 1 1 I I 1 I ' - 1 ALTERNATIVElS 6.0- FINAL MASTER Environmental ImDact Remtt CITY OF CARLSBAD Endangered Species Act, and other sensitive environmental resources, (e.9. steep slopes, watershed, important cultural resource sites). In terms of General Plan buildout projections, implementation of the Density Transfer alternative could hypothetically result in the same number of dwelling units allowed by the proposed General Plan. Residential uses planned for environmentally constrained lands could be transferred to other parts of the City. Because the Density Transfer alternative only allows density transfers to areas near main transportation corridors, public transportation facilities, and employment centers, the implementation of this alternative will result in some circulation and air quality benefits in addition to preservation of sensitive environmental resources. However, implementation of the Density Transfer alternative could result in some localized environmental impacts which are more substantial than the impacts of the proposed project in areas receiving the transferred density. Impacts from this alternative that will be more or less significant than the proposed General Plan are identified below. Hydrology The Density Transfer alternative will result in less impervious surface area than the proposed General Plan. Water absorption rates consequently will not decrease and runoff rates will not increase to the same extent. While the number of dwelling units constructed under this alternative will be similar to the number of dwelling units constructed under the proposed General Plan, the alternative will result in reduced levels of non-point source water pollutants. More non-point source pollutants are generated by single-family development than multi-family development. The geographic extent of new drainage facilities will be reduced under this alternative. Although the hydrology impacts will be less substantial than the hydrology impacts of the proposed General Plan, the hydrology impacts will be significant and mitigation will be required. Air Quality Because nearly the same number of dwelling units will be constructed under the Density Transfer alternative as under the proposed General Plan, the resulting construction-related impacts to air quality will be comparable. Due to the greater juxtaposition of residential uses and transportation facilities under the alternative, more residents may utilize public transportation. The reduced trips will result in long-term reductions in automobile emissions. While project-level air quality impacts may be less substantial than the impacts of the proposed General Plan, the resulting impacts will be significant and require mitigation. Cumulative local and regional air quality impacts will be less significant because Carlsbad is located in an air basin where state and federal pollutant standards are exceeded. The City must implement a number of measures to reduce emissions but the impact will remain significant. The cumulative air quality impact, however, may be reduced in future years as regional air quality management plans are implemented and regional pollutz& levels are reduced to meet state and federal standards. Biological Resources Due to the increased open space acreage under the Density Transfer alternative, impacts to biological resources will be less substantial than under the proposed General Plan. Significant acreage of natural habitat will still be lost in other parts of the City and the resulting impact to biological resources will be significant and require mitigation. This alternative, nevertheless, will result in the protection of 1,345 acres of additional coastal sage scrub habitat and California gnatcatchers living therein. 6.0-8 ALTERNATIVES FINAL MAS Environmental Impact Re, CITY OF CARLSBAD 1 E 1 4 I I I I 1 I 1 1 1 I 1 1 Land Use Impleme!ntation of the Density Transfer alternative will result in land use impacts that are I Substantial than the impacts of the proposed General Plan.

Local and regional trips may be reduced. Pal deficiencies may offer in the areas of concentrated residential uses. Cumulative circulation imp from local and regional through traffic will still be significant. The City has no jurisdictional control regional traffic and therefore will be unable to reduce the cumulative circulation impact to less significant. 1 Noise Under the Density Transfer alternative, more people will be living near major transportation corrid Areas SiJrrounding major transportation corridors are typically characterized by elevated noise le and greater numbers of residents will be exposed to excessive noise. The noise impacts of the Der Transfer alternative will be more substantial than the noise impacts of the proposed General F Noise attenuation barriers and appropriate project design can mitigate the potential noise impacl a less than significant level. Conclusion The Density Transfer alternative will result in impacts to hydrology, air quality, biological resour populationlhousing, and circulation impacts which are somewhat less substantial than the impact the proposed General Plan. Cumulative air quality and circulation impacts, however, will stil significant and unavoidable. In addition, the land use and noise impacts will be more Substantial 1 the related General Plan impacts. In terms of overall environmental effects, the Density Tran alternative is considered environmentally equivalent to %he proposed General Plan.

The mitigation measures consist primarily of General Plan implementation policie! programs. This EIR has been prepared as a Master EIR pursuant to AB 1888 (see Section Introduction), and will serve as the basis for the environmental review of future development prop that are consistent with the updated General Plan. The Caliifornia Environmental Quality Act (CEQA) requires the discussion of significant cumulative growth-inducing impacts of the proposed project. The following discussion addresses these issuc they relate to implementation of the updated City of Carlsbad General Plan. 7.1 The following impact areas were analyzed as part of this EIR and were found not to be significa lmoact Areas Considered But Not Found to be Potentiallv Sianificant I 0 Risk of Upset (Health, Safety, and Nuisance Factors) - Short- and Lona-Term Environmental ImDacts 7.2 CEQA and the CEW Guidelines require that an EIR identify the “relationship between local and s term uses of man’s environment and the maintenance and enhancement of long-term producth Special attention must be given to those impacts which narrow the range of beneficial uses o environment or pose long-term risks to health and safety. The EIR must also identify those rea or justifications that implementation should proceed now rather than in the future. Approximately 30 percent of Carlsbad is presently urbanized and development is concentrated ir western portions of the City. The General Plan will allow 25,389 dwelling units and approximl 45.6 million square feet of non-residential uses. Future residential development will primarily occ the vacant eastern areas and additional industrial and commercial uses will be developed in the ce portion:; of the City surrounding the municipal airport. The General Plan designates 5,781 acrc open sglace which Qenerally encompass the lagoon systems and other sensitive areas. All impacts of General Plan implementation are considered to be incremental and long-term rather immediate. By identifying the potential impacts on the environment early in the planning process City and other responsible governmental agencies can anticipate the levels of impact and can measures to reduce impacts to acceptable levels. The purpose of the updated General Plan maintain the long-lerm viability and productivity of the City through a managed growth plan as opp to allowing piecemeal development for the benefit of short-term gain. 7.3 State CEQA Guidelines define “significant effects” as a substantial adverse change in any ol physical conditions within the area affected by the project,” (Sections 15002 and 15382). Iml: are not considered to be significant or adverse if potential effects can be mitigated to acceptable leq CEQA requires the decision maker to balance the benefits of a proposed project against its unavoic environimental risk in determining whether to approve a project. If the benefits of a proposed prc I - Siqnificant Irreversible Environmental Chanaes 1 I - ANALYSIS OF LONG-TERM EFFECTS 7.c 1 I FINAL MASTER Environmental lmDact Rewrt outweigh the unavoidable adverse environmental effects, the adverse environmental effects may be considered “acceptable” (CEQA Guidelines Section 1 5093). This EIR identifies two areas of unavoidable impact, as defined by CEQA, that will result from the implementation of the Carlsbad General Plan. The implementation of the General Plan will have direct and unavoidable significant impacts on air quality and traffic circulation based on the identified significance thresholds. Alternatives examined in Section 6.0 of this EIR were analyzed to determine whether the impacts to air quality and traffic circulation could be reduced to a less than significant level. The San Diego Air Basin contains pollutant levels that exceed the state and federal standards for air quality. Implementation of the General Plan will result in additional residential and non-residential uses in Carlsbad and the amount of emissions generated within the City will consequently increase. The mitigation measures identified in this EIR will reduce the amount of emissions generated as a result of General Plan implementation. However, the combined emissions from Carlsbad and other cities in the San Diego Air Basin will continue to exceed the state and federal air quality standards. The cumulative impact to air quality will remain significant regardless of the mitigation measures implemented by Carlsbad. Carlsbad traffic is composed of both traffic generated by local land uses and traffic from regional activity. Local traffic will increase as development occurs according to the updated Carlsbad General Plan. The roadway plan contained in the Circulation Element can generally accommodate the increased traffic. Several intersections in the City will exceed acceptable service levels by buildout due to the combined effect of local and regional traffic. Planned intersection improvements will not fully mitigate the cumulative impact of future traffic volumes. None of the alternatives will reduce cumulative air quality or traffic circulation impacts to less than significant. 7 -4 Growth-lnducina lmoacts Adoption of the updated Carlsbad General Plan will not cause growth, but rather is an approach required of cities and counties by the State of California to accommodate, manage, and control growth. Implementation of the proposed General Plan will provide for increases in the City’s residential population and additional development of the commercial and light industrial sectors. Demand for City services will increase due to the additional development allowed by the plan. The General Plan and associated infrastructure and public service master plans will accommodate the increased demand and the new development will generate new revenue to fund expansion of public services. The environmental effects related to individual projects will need to be assessed as such projects are proposed. The City will impose conditions on the approval of such projects to reduce environmental effects. Periodic updating of the General Plan and its supporting documents will assist in the identification and development of necessary mitigation measures as development within the City occurs. 7.5 Cumulative ImDacts The California Environmental Quality Act Guidelines define cumulative effects as “two or more individual effects that, when considered together, are considerable or which compound or increase other environmental impacts”. The Guidelines further state that the individual effects can be the various changes related to a single project or the changes involved in a number of other closely related CITY OF CARLSBAD 7 .O-2 ANALYSIS OF LONG-TERM EFFECTS FINAL MAS1 Environmental Imnact Rei CITY OF CARLSBAD B 1 1 I 1 1 I I l 1 i 1 I I i I 1 ANALYSIS OF LONG-TERM EFFECTS 7.c 1 past, present, and reasonably foreseeable future projects (Section 1 5355). The Guidelines allov the use of two alternative methods to determine the scope of projects for the cumulative im analysis: 0 1 of the agency. 0 List Method - A list of past, present, and reasonably anticipated future pro, producing related or cumulative impacts, including those projects outside the co Regional Growth Projections Method - A summary of projections contained ii adopted general plan or related planning document which is designed to eval regional or areawide conditions (Section 1 51 30). The updated Carlsbad General Plan establishes policy to guide future development within the City its implementation is long-term in nature. The Regional Projections Method is more appropriate the List Method because the List Method only accounts for projects in the short-term. Regional grc projections from General Plans and regional plans include both short- and long-term projects. Regional Growth Projections The Sari Diego Association of Governments (SANDAG) projects regional growth for the greater Diego area. Local General Plan land use policy is incorporated into SANDAG projections. The r recent set of adopted growth projections are contained in the SANDAG Series 7 Regionwide Fore for 198!5 through 201 0. SANDAG has recently updated the regional growth projections but the projections have not been adopted to date. As a result, the Series 7 projections serve as the basi the cumulative impact analysis. The CoiJnty of San Diego is divided into subregions, (or Major Statistical Areas), in the Seri Regionvvide Forecast. Carlsbad, along with San Dieguito, the City of Oceanside, and Camp Pendl (USMC) compose the North County West Major Statistical Area (MSA). San Dieguito is a commi that is comprised of both County of San Diego land and City of Encinitas land. The geogra boundaries of the cumulative impact study area correspond to the boundaries of the North CO West wbregion with the exception of the Camp Pendleton area. Camp Pendleton is excluded fron cumulative impact analysis because the forces affecting growth at the camp are distinct fron forces affecting growth in the rest of the subregion. Forecasting future development at C Pendleton requires using a different set of variables and accounting for national base realign1 policy. Map 7.0-1 : Cumulative Impact Study Area, shows the cumulative impact study area in reL to the greater San Diego region. - Table 7.0-1: Growth Forecasts for the North County West Major Statistical Area (Without C Pendleton), shows the Series 7 projections for population growth and residential development fol year 20110.

Cumulative Impacts Soils arid Geoloay Future clevelopmerit in the North County West MSA will increase the number of people expose1 earthquake and other geologic hazards. Future development will be constrained by steep sloi landslides, and soils with high clay content. Erosion and siltation rates will be accelerated earthwork required for new development. Cumulative impacts related to geologic conditions car mitigated by impleimentation of local grading ordinances, standard structural safety regulations, the public safety and development policies and programs contained in local General Plans. 1 Hvd rol ogy As development occurs throughout the North County West MSA, the amount of impervious surfa will increase. Water absorption rates will subsequentlydecrease and runoff rates will increase. h drainage infrastructure will be required to prevent flooding. Non-point source pollutants will incre from new development and will impact the local coastal lagoons and ocean waters. The potential sedimentation of the lagoons will increase from grading and construction. Impacts related to non-pi source pollutants and sedimentation can be mitigated by implementation of Best Management Practi according to state and local National Pollutant Discharge Elimination System permits and regic efforts to preserve the lagoons. Air Quam The San Diego Air Basin contains pollutant levels that exceed the state and federal standards for quality. The development forecasted for the North County West MSA will be associated v increased emission levels. Potential emissions will be partially reduced by the implementation of IC air quality policy and the San Diego County Air Pollution Control District Regional Air Quality Strates - 8 ANALYSIS OF LONG-TERM EFFECTS 7 .O- FINAL MASTER Environmental Imnact Remtt (RAQS). However, the combined emissions from the North County West MSA and other developed areas in the County will continue to exceed the state and federal air quality standards. The cumulative impacts to air quality will be significant. The City will implement a number of measures to reduce the amount of emissions generated in Carlsbad but the cumulative impacts will remain significant. The cumulative impacts to air quality may be reduced in future years as regional air quality management plans are implemented and regional pollutant levels are reduced to meet state and federal standards. Bioloclical Resources Sensitive biological resources will be impacted by anticipated development in the North County West MSA but potential cumulative impacts can be mitigated by regional preservation efforts and project- level mitigation programs. The North County West MSA contains large expanses of coastal sage scrub in addition to riparian and lagoon habitat. These habitat support endangered and threatened species of plants and animals, and migratory water fowl. Regional efforts to preserve the lagoons and the North County Natural Communities Conservation Planning Effort will help protect sensitive biological resources in the North County West MSA. Habitat will also be preserved in the open space designated in the Oceanside, Carlsbad, and San Dieguito areas. All future development projects will be reviewed according to CEQA for impacts to biological resources and potential impacts to sensitive biological resources will require implementation of mitigation programs. PoDulation/Housing Population in the North County MSA will increase by 84 percent from 217,052 persons to 298,559 persons and housing will increase by 94 percent from 81,830 dwelling units to 158,891 dwelling units. The substantial change in population and housing is considered a cumulative impact which can be mitigated. The North County West MSA contains more residential uses than commercial and industrial uses and the Jobs-to-Housing ratio is unbalanced when compared with the San Diego region. Recent development primarily consists of single-family dwellings and new residents often commute to other areas in the County for employment. Many residents of Oceanside, however, are employed locally at Camp Pendleton. Planned development in the North County West MSA includes both residential and non-residential uses. The establishment of industrial, office, and commercial uses will provide jobs and the Job-to-Housing ratio will improve. Implementation of local Housing Elements will provide affordable housing for lower-income residents. Land Use Large expanses of vacant land in the North County West MSA will be converted to urban uses and the character of the landscape will be altered. Long-range land use plans exist for the individual jurisdictions in the North County West MSA. Potential land use incompatibilities can be mitigated by implementation of the local land use plans. Coordination between the jurisdictions will facilitate compatible development along jurisdictional boundaries. Circulation The North County West MSA presently experiences traffic congestion along major arterials due to commuting and through traffic. Planned development within the region will generate additional traffic which will further impact the regional circulation system. The planned mix of residential, commercial, office, and industrial uses will decrease some of the traffic of residents commuting to other cities for employment. Future circulation impacts will be partially mitigated by participation in the SANDAG CITY OF CARLSBAD - 7.0-6 ANALYSIS OF LONG-TERM EFFECTS FINAL MAS Environmental Imnact Re CITY OF CARLSBAD I i I I I 1 I I I i 1 1 I I I I Regional Transpoitation Plan by the individual North County West MSA cities. However, cumulaitive circulation impact cannot be mitigated to less than significant due to the large volun through traffic over which the City has no jurisidctional control and physical constraints to circul, 1 improvements. Cultural and Paleontoloaical Resources The Noith County West MSA contains valuable cultural and paleontological resources. Prehistoric archaeallogical remains are abundant in riparian and lagoon areas and the older parts of Carlsbad, Dieguito, Oceanside contain some structures with historicat significance. Rare fossils have been fc in the geologic formation underlying the coastal bluffs and hills in the North County West IL Anticipated development will require grading and earthwork which could impact potentially occui archaealogical and paleontological resources. Potential impacts can be mitigated by implementation of local policy pertaining to cultural and paleontological resources. In additior proposed projects will be reviewed pursuant to CEQA and mitigation measures will be develope( potential impacts. Future development will primarily occur in vacant areas and historic resourci currently urbanized areas will not be affected. Historic agricultural properties may be impacted potential impacts can be mitigated through application of the CEQA environmental review proce Noise Anticipated development will generate short-term noise during the construction process. Increi development densities will increase traffic volumes and associated noise levels. Implementing I noise ordinances, constructing buildings according to state acoustical standards, and proper land planning can mitigate noise impacts to noise-sensitive land uses. Health, Safetv, and Nuisance Factors The use and transportation of hazardous materials will increase as development proceeds in the N County West MSA. State, county, and local regulations will preclude significant public health haza Residential develolpment will occur in areas that are presently or have been used for agricul production. Chemical residue may exist in soil and affect the health of future residents. Plar residential neighborhoods may be adjacent to ongoing agricultural operations and public health mal affected by continual use of agricultural chemicals. Impacts related to past and current agricult activity can be mitigated by soil testing prior to the development of individual projects and the US buffers between agricultural and residential areas. Light and glare levels will increase from additional lighted parking lots, vehicle traffic, street lights, light-colored and glass building exteriors. Aesthetics The aesthetic character of the North County West MSA will change. The landscape will become n urbanized, some coastal and lagoon views could be obstructed, and scenic corridors coulc degraded. Some of the views of agricultural and natural areas will be lost or will be transforme views of residential, commercial, and industrial development. Impacts to aesthetics can be mitigc by implementation of Local Coastal Plans and local design guidelines. In addition, future developm projects will be reviewed pursuant to CEQA and mitigation measures will be developed for signific aesthetic impacts. II - - 1 ANALYSIS OF LONG-TERM EFFECTS 7.0 FINAL MASTER Environmental ImDact RemH Utilities and Public Services As development occurs in the North County West MSA, the demand for utilities and public services will incrementally increase. New development will require power, water, and sewer service. Transmission lines, pipelines, water reservoirs, and regional facilities to treat drinking water and sewage must be constructed. The development of these types of infrastructure will require land and easement acquisitions. Solid waste generation will also increase as development proceeds. Because landfill space is limited in San Diego County, the cumulative impact could be substantial. If the Source Reduction and Recycling Element for each city within the North County West MSA is fully implemented, solid waste generation will be reduced by 50 percent by 2000. As the population in the North County West MSA expands, the demand for fire protection, law enforcement, education, and parks and recreation services will increase. Land must be acquired for new service facilities, equipment must be purchased, and additional personnel hired to accommodate the demands of anticipated development. Impacts to utilities and public services can be mitigated by the implementation of local infrastructure and public service master plans, appropriate land use planning, and local growth management policies. The utility requirements of future development projects will be assessed by the appropriate jurisdiction and infrastructure improvements can be included as conditions of approval. As development proceeds, the tax base will expand and supply additional funds to develop and maintain new public services. Natural Resources Substantial acreage of agricultural land exists in the North County West MSA. Future development will result in the conversion of farmland (inchding Prime Farmland) to urban uses. Conversion will only occur when the profits from economic development exceed the profits from agricultural production. Local and County agricultural and open space policy will preserve some farmland acreage in the North County West MSA and mitigate cumulative impacts.
