PLN CIT$-JF CARLSBAD - AGEND.-,BILL TITLE: APPROVAL OF A MASTER PLAN AMENDMENT, -TENTATIVE MAP AND OTHER DISCRETIONARY APPLICATIONS FOR PLANNING AREA 24 OF THE AVIARA MASTER PLAN. IECOMMENDED ACTION: Both the Planning Commission and staff are recommending that the City Council direct the City Attorney to prepare documents APPROVING the Mitigated Negative Declaration C 90-15, LCPA 90-6 and HDP 90-20 and INTRODUCE Ordinance No. $!?-,‘/ , APPROVING MP-177(D). ITEM EXPLANATION On May 29, 1991, the Planning Commission conducted a public hearing and approved without modification (6-1 Erwin) a Master Plan Amendment, Tentative Map, Hillside Development Permit and Local Coastal Program Amendment for Planning Area 24 of the Aviara Master Plan. Planning Area 24 is located at the southeast corner of the intersection of Alga Road and future Poinsettia Lane. The tentative map includes 118 minimum 7500 square foot single family residential lots , 4 open space lots (15.2 acres in area) and a local street system over the 54.61 acre site. The proposed Master Plan Amendments to Planning Area 24 include the following: A. Change permitted single family lot sizes from small lot (minimum 5000 SF) to minimum 7500 SF in area. B. Modify Planning area development standards to be consistent with the minimum development standards of the R-1-7500 zone and other up-to-date citywide ordinances and policies. c. Reduce maximum permitted dwelling unit potential (from 193 du's to 118 duls) within Planning Area 24 while increasing open space from the anticipated Master Plan total of 10.9 acres to 15.2 acres (increase of 4.3 acres). The proposed project complies with all applicable City ordinances, and policies and is consistent with the goals of the Aviara Master Plan. More detailed information is included in the attached staff report to the Planning Commission. ENVIRONMENTAL REVIEW On May 29, 1991 the Planning Commission recommended approval of the Mitigated Negative Declaration issued by the Planning Director on March 28, 1991. PAGE 2 OF AGENDA BILL NO. FISCAL IMPACT As discussed in the Zone 19 Local Facilities Management Plan, because all required improvements are to be funded by development, no fiscal impacts to the City will result from this 118 dwelling unit tentative map and associated applications.

IMPACTS STATE CEQA GUIDELINES, Chapter 3, Article 5, section 15063 requires that the City conducr an Environmental Impact Assessment to determine if a project may have a significant. effect on the environment. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological and human factors that might be impacted by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report or Negative Declaration. * A Negative Deck&a may be prepared if the City Perceives no substantial evidence that the project or any of its aspects mause a signiikant effect on the environment. On the checklist, “NO” will be checked to indicate this detamination. * An EIR must be prepared if the City determks that there is substantial evidence that any aspect of the project may cause a sinnificanr effect on the environment. The project may qualify for a Negative Declaration however, if adverse impacts are mitigated so that environmental effects can be deemed insitificant. These findings are shown in the checklist under the headings ‘YES-sig” and “YES-kig” respectively. A discussion of potential impacts and the proposed mitigation measures appears at the end of the form under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attention should be given to discussing mitigation for impacts which would otherwise be determined significant. .

There l*;ert no public comments received in response to the Conditional Negative Declaration. Phvsical Environment 1. The project site contains no unstable earth conditions. The project as proposed includes extensive grading (60’ of fill) within the Phase IV area located adjacent to the alga Road/Poinsettia Lane future intersection. This f5ll can however be adequately developed upon, through implementation cr‘ standardized soils compaction and stability measures. No unstable earth conditions will result from project development. 2. Grading of the project site consistent with the proposed tentative map would require considerable earth movement 342,400 cubic yards cut 578,000 cubic yard, fill. Potential visual effects associated with this grading shall be mitigated through conformance with the design guidelines and development standards of the City’s Hillside Ordinance. Visual impacts associated with project land from modification can be mitigated through complete hydroseeding and landscaping of manufactured slopes and future implementation of project landscaping. 3. Drainage and erosion control facilities (desiltation basins, storm drain and terrace drains) will be incorporated into the project to adequately reduce potential soil erosion impacts. The project shall also be conditioned to rkbly landscape all manufactured slopes. 4. Potential erosi- wts to Batiquitos Lagoon will be adequately mitigated as discussed in response #3 above. 5. Construction emission and fugitive dust generation impacts associated with project grading are considered short term and insignificant. Dust generation can be adquately controlled &rough watering operations. Air quality impacts associated with future development of housing upon this area is not considered signifkant in itself. bng term full mitigation of regional air qualitys impact shall require that dependence upon the automobile be reduced regionally and statewide. -6- 6. 7. 8. 9. 10. 11. 12. 13. 14. [n that no strucNfal development is proposed at this time, impacts to ti movement are not antic-Pare,-+. Air quality i.mp~B from dust generation can be adequately controlled through watering 0peraricr.s during project grading. This project wi.l.l not change the course or flow of water as no streams are located in the immediate areI and all drainage waters will be handled by proposed drainage k&ties. Development of this project (tentative map grading and road construction) w-ill create impenjo:j surfaces which would reduce absorption rates and incrementally increase runoff velocities. Houei,er. to accommodate this increased nmoff, drainage facilities will be incorporated into this project azt future residential deveiopment upon the site, thereby mitigating this concern. rmplememation of the proposed project will incrementally contribute to the depletion of fossil fxe:eis during grading operations and other natural resources required for project roadways. This shorr rem incremental impact is not regarded as significant. See #9 above. Two archaeological sires (SDi-6753, 6754) are located upon the subject properry. As a condition cf approval of EIR 83-2(A) a testing program was carried out at these two sites. Most of the SDi 67% site is outside of the Aviara project area and the portions of the site that is within the property has had the anticipated impacts mitigated through testing and analysis of recovered artifacts. The significance testing undertaken at SDi 6753 resulted in a finding that the site is potentially significant. h data recovery program is recommended to be undertaken a? this site prior to the initiation of grading. The data recovery program planned for SDi 6753 will involve the excavation of six square meter units. Implementation of this data recovery program at this sire will adequately mitigate potential cultural resource impacts. This has been included as a condition for the project. The project site includes environmentally significant property which was placed under deed restriction by the California Coastal Commission upon approval of Master Plan 177. This proposal will encroach into 2.01 acres of the protected habitat including 1.34 acres of sage scrub and .67 acres of Chapparal. However, as mitigation for this encroachment, the project applicant is proposing to give back as deed restricted open space 2.79 acres of habitat which is of higher quality including 2.55 acres of sage scrub, and .24 acres of Chaparral. The increase in Coastal Sage Scrub by .78 acres is potentially beneficial to the California Gnatcatcher, which utilizes the habitat. No significant w to the abovementioned coastal sage scrub habitat are anticipated in that project landscaping prqmaed adjacent to this habitat shall be required to be compatible and non-invasive. As stipulated in MP-177, conversion of agricukural lands shall be permitted upon payment of a@hu.ral conversion fees. In accordance, the project applicant has already paid to the State Coastal Conservancy agricultural mitigation fees required for the development of the project site. -7- D[SCUSSlON OF ENVIRONMENTAL EVALUATION (cont’dl 15. AS discussed in #I2 above, the previously deed restricted coastal sage habitat (or comparable qL;a;xr,- habitat) will be maintained in open space. Accordingly, no significant impacts to habitat or species & anticipated. 16. The projecr as proposed preserves in open space the majority of the previously deed restricted c-as;3: sage scrub habitat. In addition, the project preserves in open space 4.3 additional acres than an[ici,-a:?l under MP-177. The addition of this open space in association with previously deed res[ic[ed cztlr, space will function to provide adequate corridors for the movement of animals throughour the p:-,:?.-: site. 17. Development of this project will be consistent with the General Plan, Master Plan 177 (as arnende,i: and the Mello 1 LCP (as amended). The land use changes proposed will be internally compatible as feel: as being compatible with adjacent uses. 18. AS discussed in the ‘Zone 19 Local Facilities Management Plan, with the payment of all fees and the implementation of all improvement conditions (ie. upgrading of the Batiquitos sewer pump station. consrruction of Alga Road and Batiquitos Drive), all public facilities and services will be available CO meer the demands of the future development of 120 single family residences proposed on the projec: site. 19. Although the Tentative Map and Master Plan Amendment does not propose any actual produc: development, any subsequent dwelling unit construction on site shall not be permitted until the Batiquitos Sewer Pump Station is upgraded. 20. Construction of the project (grading and road development) may result in short term insignificant construction noise impacts upon surrounding existing and proposed residences. Otherwise, the future residential uses on the subject property will be acoustically compatible with surrounding existing and future residential uses. At the time that future residences are constructed upon the subject property, traffic noise impacts from Alga Road/Poinsettia Lane shall be required to be mitigated. 21. 22. Future lighting utilized onsite will be directed so as to not impact adjacent future views. Because this is a residential project it will not involve a significant risk of an explosion or the release of hazardous substances. 23. The proposed m density of 2.2 du/acre is well below the density permitted upon the site (3.6 du/acre) per ti Avlrrr Master Plan. In view of the reduced density, overall project environmental effects should be reduced. 24. The project will provide additional housing units to meet existing demand. 2s. A total of 1,200 average daily vehicle trips wiU be generated by the project ‘which will not significantly impact the circulation system as discussed in EIR 83-2(A) and LFMP-19. DISCUSSION OF ENVIRONMENTAL EVAIJJATION (cont’dl 26. 27. 28. 29. 30. 31. 32. The demand for @kg facilities created by this project will be satisfied onsite. Two garage spaces ,,,,..I: be provided for each unit and adequate on street guest parking will be provided throughout the pr,Cj?:T The project will add 1200 ADT to Alga Road. Other surrounding streets will also carry ponior5 of this traffic. This minor increase in traffic upon ti surrounding streets is not considered significant. The project site is outside of the Airport Influence Area for Palomar Airport. Two vehicular access points are proposed for the project and are not located to cause cotilic:~ with intersections with Alga Road. The project will not interfere with emergency response plans. Grading of the subject property would result in a short-term but unavoidable visual impacts. this impact can, however, be mitigated through the following mitigation measures: (1) all manufacrure:‘, slopes shall be required to be fully hydroseeded and itrigated immediately following rough grading, ant (2) all manufactured slopes shall be required to be undulated and contour graded consistent with the Hillside Development Ordinance. When a future site development plan is processed over this properry, rich landscaping shall be incorporated into the project design. As proposed, the project will have no impact on existing recreational opportunities. [mplemenration of this project will, however, ensure the preservation of 15.2 acres of natural open space areas. -9- &vN..YSIS OF c a) Phased development of the project, b) alternate site designs, c) alternate scale of development, d) alternate uses for the sire, e) development at some future time rather than now, f) alternate sires for the proposed, and g) no project alternative. a) b) d d) d f) g) The 120 residential 10~s proposed with this project will be developed in 4 separaie phases. Phasing, however will not likely result in an environmentally superior pre;ec:. This project has been designed consistent with the Aviara Master Plan - Planning .t-ez 24 conceptual site plans and the City? Hillside Ordinance. This project will aijo preserve additional site acreage in natural open space than originally anticipated under the existing Master Plan. The potential scale (number of dwelling units) of this project will be reduced from 193 du’s to 120 du’s with the approval of this Master Plan Amendment Any change of land use upon the subject property would necessitate a General Plan Amendment and a Master Plan Amendment. In that this project would result in the development of low-medium density residential (2.2 du/ac), it is regarded as an environmentally preferable alternative. The project will result in the grading and subdivision of Aviara Planning Area 24. A future site development plan application will be required to be processed through the City. No structural development will be permitted on-site unless all public facilities and available concurrent with demand. In accordance with these requirements, the projecr will likely be developed in increments and over time. The project is proposed in a Master Plan area over which an EIR has already been certified (EIR 83-2(A)). As discussed in the EIFt., this site is regarded as the environmentally preferable site for the proposed project. Tbr “no project” alternative is not in conformance with the General Plan/Master Plan mtion for the property. Hence, it is not regarded as environmentally preferable. -lO- DETERMINATION (To Be Completed By The Planning Department) On the basis of this initial evaluation: I find the proposed project COULD NOT have a significant effect on the environment, and a NEG.;::‘.

B) That based on the evidence presented at the public hearing, the Commission recommends APPROVAL of CT 90-15, based on the following findings and subject to the following conditions: Findinns: 1. The project is consistent with the City’s General Plan and MP-177 since the maximum permitted density of 2.16 du’s/acre is within the density ‘range of O-4 du’s/acre specified for the site as indicated on the Land Use Element of the General Plan, and is at or below the growth control point of 3.2. 28 . . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 2. 3. 4. 5. 6. 7. 8. 9. 10. The site is physically suitable for the type and density of the development permitted through Master Plan 177. , The Planning Commission has, by inclusion of an appropriate condition to this project, ensured that the final map will not be approved unless the City Council finds that sewer service is available to serve the project. In addition, the Planning Commission has added a condition that a note shall be placed on the final map that building permits may not be issued for the project unless the City Engineer determines that sewer service is available, and building cannot occur within the project unless sewer service remains available, and the Planning Commission is satisfied that the requirements of the Public Facilities Element of the General plan have been met insofar as they apply to sewer service for this project. School fees will be paid to ensure the availability of school facilities in the Carlsbad School District. Park-in-lieu fees are required as a condition of approval. All necessary public improvements have been provided or will be required as conditions of approval. The applicant has agreed and is required by the inclusion of an appropriate condition to pay a public facilities fee. Performance of that contract and payment of the fee will enable this body to find that public facilities will be available concurrent with need as required by the General Plan. The proposed project is compatible with the surrounding future land uses since surrounding properties are designated for single family residential development on the General Plan. This project will not cause any significant environmental impacts and a Mitigated Negative Declaration has been issued by the Planning Director on March 28, 1991 and RECOMMENDED FOR APPROVAL by the Planning Commission on May 29, 1991. In approving this Mitigated Negative Declaration the Planning Commission has considered the initial study, the staff analysis, all required mitigation measures and any written comments received regarding the significant effects this project could have on the environment. The applicant is by condition, required to pay any increase in public facility fee, or new construction tax, or development fees, and has agreed to abide by any additional requirements established by a Local Facilities Management Plan prepared pursuant to Chapter 21.90 of the Carlsbad Municipal Code. This will ensure continued availability of public facilities and will mitigate any cumulative impacts created by the project.

II. PROJfXl- DESCRIPTION AND BACKGROUND This project is a Master Plan Amendment, Local Coastal Program Amendment, Tentative Tract Map, and Hillside Development Permit for Planning Area 24 of the Aviara Master Plan 177. Planning Area 24 is located at the southeast comer of the intersection of Alga Road and future Poinsettia Lane. The subject property is zoned PC and is under a Combination General Plan Designation of RLM/RM/OS/RC/N. The existing Master Plan designates the site for a maximum density of 3.6 du/ac. As shown on Exhibits “A” and “B”, the Tentative Map includes 118 minimum 7500 SF single family residential lots and 4 open space lots (15.2 acres) over the 54.61 acre Planning Area. The project open space areas are predominantly comprised of dense coastal sage and chaparral covered slopes. The northwestern comer of the Planning Area (a MP-177(D)/LCPA90-6/W 90-lS/HDP 90-20 - AVIARA PA24 MAY29,1991 PAGE2 portion of lot 22) will be dedicated and graded for future Poinsettia Lane. The project would have a density of 2.16 du/ac. This density is well below the site’s maximum permitted density of 3.6 du/ac. The proposed project would be accessed via Alga Road, which is located along the southern and western perimeters of the property. Two 60 foot wide Local Streets (Nightshade Drive and Caspian Lane) would be constructed to intersect with Alga Road and provide access to the project’s residential lots. Proposed project grading includes 375,000 cubic yards of cut and 590,000 cubic yards of fill (including the existing onsite stockpile which totals 215,000 cubic yards). Of the total project grading, 21,500 cubic yards is for the construction of a portion of Poinsettia Lane. The proposed Master Plan Amendments to Planning Area 24 include: A. Change permitted single family lot sizes from small lot (minimum 5000 SF) to minimum 7500 SF in area. B. Modify Planning Area development standards to be consistent with the minimum development standards of the R-1-7500 zone and other up-to-date citywide ordinances and policies. C. Reduce maximum permitted dwelling unit potential (from 193 du’s to 118 du’s) within Planning Area 24 while increasing open space from the anticipated Master Plan total of 10.9 acres to 15.2 acres (increase of 4.3 acres). The northwestern portion of the project site has been disturbed as a consequence of a City approved stockpile operation. The central and northeastern portions of the site exist as level ridge tops formerly under agricultural use. These ridge tops are surrounded by side slopes which are vegetated with chaparral and coastal sage scrub habitat. The site is surrounded by agricultural uses to the north and east, Alga Road to the south and undeveloped single family residential Planning Area 25 to the west. This project is located within the Mello I segment of Carlsbad’s Local Coastal Program. In that the existing Master Plan serves as the implementing ordinance for this area of the Mello I Local Coastal Program, a Local Coastal Program Amendment shall be required to be processed through the California Coastal Commission. MP-177(D)/LCPA 90-6/~1’ 90-lS/HDP 90-20 - AVIARA PA 24 IWiY29,1991 PAGE 3 III. ANALYSIS MASTER PLAN AMENDMENT - MP-177(D) Planning Issues 1. Are the proposed land use changes consistent with the intent of Master Plan 177? 2. Will the proposed land use change from small lot single family (minimum 5000 SF) to standard single family (minimum 7500 SF) be consistent with the General Plan? 3. Are the proposed land use changes compatible with surrounding uses? 4. Are the proposed development standards revisions consistent with the intent of Master Plan 177? DISCUSSION As proposed, the land use changes (small lot single family to R-1-7500 single family) and development standards revisions in Planning Area 24 are consistent with the intent of Master Plan 177 and would be consistent with the General Plan. This proposed land use change would be consistent with the Master Plan goal of ensuring that development is compatible with existing and future surrounding uses. Specifically, the properties to the west and south (Aviara Planning Areas 25 and 26 respectively) are planned for the development of R-l -7500 single family residential, and the properties to the north and east have a General Plan designation of RLM (Residential Low Medium 3.2 du/ac.) Although this land use change would reduce the number of potential small lot single family residences within Master Plan 177 from 15% to 10% of total Master Plan dwelling units, the Master Plan housing product mix (63% multi-family/37% single family) would be unchanged through this proposed amendment. Therefore, this revision would be consistent with the Master Plan goal of providing “a well balanced and functional mix of residential uses. This land use change will result in the reduction in permitted number of dwelling units within Planning Area 24 from 193 to 118. The site density will be reduced from 3.6 du/ac. to 2.16 dy/ac. This density would be consistent with the combination General Plan designation of (RM/RLM/OS/RC/N) over the Master Plan. In addition, the reduction in density of this Planning Area to 2.16 du/ac. would ensure compatibility with surrounding properties, which are designated RLM (3.2 du/ac.). As discussed above, the proposed land use revisions from small lot (minimum 5000 SF) single family to standard single family (minimum 7500 SF) would be compatible with surrounding future single family residential. My-177(D)/LCPA 90-6/c I’ 90-lS/HDP 90-20 - AVIARA PA 24 MAY 29, 1991 The proposed development standards revisions for Planning Area 24 would also be consistent with the intent of Master Plan 177. The revised development standards would be as or more restrictive than the standards of the R-1-7500 zone, and would ensure consistency of all R-l -7500 Master Plan neighborhoods. The specific development standard changes include the following: 1. Revise the maximum structural height limit from 28 feet as measured to the midpoint of the roof to 30 feet as measured to the peak of the roof. This revision will likely reduce the heights of the single family residences proposed in this Planning Area. 2. Require that 15% of the dwelling units constructed in this Planning Area be a maximum of one story (22 feet measured to the highest roof peak) in height. This Planning Area currently does not require any one story dwelling units. 3. Require that all dwelling units be setback a minimum of 30 feet from the SDG&E easement which is located within the northeast comer of the Planning Area. This setback would ensure utility setback consistency with all other Aviara Planning Areas. 4. Require that 36 of the proposed 120 dwelling units have a 24 foot front yard setback instead of the required 20 foot front yard setback. This amendment will create variety in the neighborhood street scene. 5. Replace all existing Planned Development standards with R-1-7500 development standards. LOCAL COASTAL PROGRAM AMENDMENT- LCPA 90-6 Planning Issues 1. Is the proposed Local Coastal Program Amendment consistent with the zoning and General Plan designation of the subject property? DISCUSSION California State Law requires that the Local Coastal Program, General Plan and zoning upon a subject property be consistent. The project site is located within the Mello I Local Coastal Program. Master Plan 177 constitutes the zoning for the subject property, and also functions as the implementing ordinance for this section of the Mello I Local Coastal Program. As discussed above, the change from small lot single family to standard single family lots (minimum 7500 SF) would be consistent with the Master Plan’s combination General Plan designation of RM/RLM/OS/RC/N. In that Master Plan 177, as amended and ,4 * My-177(D)/LCPA 90-~/LA 90-lS/HDP 90-20 - AVIARA PA 2% MAY 29, 1991 the underlying Mello I Local Coastal Program must be found to be in conformance, staff concludes that LCPA 90-6 is consistent with the zoning and the General Plan. TENTATIVE TRACT MAP/HILLSIDE DEVELOPMENT PERMIT - CT 90-15/HDP 90-20 Planning Issues 1. Does the proposed Tentative Map satisfy all requirements of the Subdivision Ordinance and the State Map Act? 2. Does the proposed Tentative Map comply with the requirements of the Hillside Ordinance (Chapter 21.90 of the Carlsbad Municipal Code)? 3. Is the proposed project in compliance with the Interim Open Space Ordinance? 4. Does the proposed project Adequately mitigate encroachment into previously deed restricted coastal resource areas? 5. Is the proposed project in compliance with the Mello I Local Coastal Program? 6. Is the proposed project in compliance with the Zone 19 Local Facilities Management Plan? DISCUSSION Tentative Map - CT 90-15 The 54.6 acre, 122 lot ( i.e. 118 residential and 4 open space) Tentative Tract Map conforms with all requirements of the R-l -7500 zone, Carlsbad’s Subdivision Ordinance and the State Map Act. All proposed residential lots will front on publicly dedicated streets, have been designed to drain adequately and meet the minimum development standards of the R-1-7500 zone. Specifically, all lots are: 1. A minimum of 7500 square feet in area; 2. A minimum of 60 feet in width; 3. A minimum of 90 feet in depth; and 4. Do not exceed a depth to width ratio of 3:l. Hillside Development Permit - HDP 90-20 The Tentative Map for Aviara Planning Area 24 generally complies with all development and design provisions of the Hillside Ordinance. Consistent with the design guidelines of the Hillside Ordinance, the Tentative Map has been designed to: (1) preserve significant environmental resources, (2) incorporate terraced lots and curvilinear streets into the project’s design, and (3) maintain all major steep slopes in open space. /4 4. . MP-177(D)/LCPA 90-6/cl’ 90-lS/HDP 90-20 - AVIARA PA 24 MAY 29, 1991 Total project grading would include 375,000 cubic yards of cut and 590,000 cubic yards of fill (including the existing onsite stockpile which totals 215,000 cubic yards) over 37.80 acres (15,616 cubic yards per disturbed acre). Of the total project fill, 457,500 cubic yards (77%) is required for the development of Unit 4 of this Tentative Map (See Exhibit “D”). Master Plan 177 designates Unit 4 of Planning Area 24 for residential development. The Master Plan Environmental Impact Report (EIR 83-2A) identified no significant environmental resources in this area of the Master Plan. As discussed in Attachment “A”, the grading required for the development of Unit 4 of CT 90-15 is directly a consequence of two Circulation Element Roads (Alga Road and Poinsettia Lane). Specifically, the natural topography of Unit 4 (without the existing stockpile) is up to 50 feet below the existing grades of Alga Road and Poinsettia Lane. In order for Unit 4 to be developed, consistent with Master Plan 177, it must be raised to an adequate elevation to drain and gravity sewer to existing utility systems in Alga Road. Development of the Unit 4 site at an elevation lower than that proposed, would: (1) require the use of a sewer pump station (in violation of City Engineering Policy) and (2) would create a “sump” drainage condition. In accordance with these findings, this grading is exempted under Section 95.070(2) of the Hillside Ordinance. Deduction of this grading amount, results in a net project grading total of 7407 cubic yards per disturbed acre. This amount of grading is defined as “acceptable” under the Hillside Ordinance. A slope analysis study was conducted for the proposed Tentative Map (See Exhibits “G”- “H”). As designed, the project does not encroach into any major 40% slope areas. To a large degree, these slope areas have already been placed under an open space deed restriction by the California Coastal Commission. The proposed Tentative Map includes one manufactured slope (north of lots 100-102) which exceeds a height of 30 feet. The construction of this maximum 50 foot high slope is necessary to prevent grading encroachment into an offsite canyon to the north. Although the Conceptual Development Plan for Planning Area 24 (Aviara Master Plan - pg. 164) anticipated offsite grading into this canyon, subsequent environmental study indicates that this canyon merits preservation in open space based upon the sighting of Blacktailed Gnatcatchers within this coastal sage scrub and chaparral vegetated canyon. In that this manufactured slope as proposed, preserves this native canyon, it is exempted from complying with the 30 foot high manufactured slope height limit of the Hillside Ordinance (Section 21.95.070(3)). The project applicants are proposing to enhance the appearance of all manufactured slopes through a landscape program (See Exhibits “[“-“.I”). In addition, a widened landscaped parkway (15.5-20 feet wider than the required right-of-way) along Alga Road and Poinsettia Lane is proposed to enhance the appearance of the project. t ,- ,L- MP-177(D)/LCPA 90-6/~l’ 90-lS/HDP 90-20 - AVIARA PA 24 MAY 29, 1991 Interim Open Space Ordinance The project as proposed is in compliance with the City’s Interim Open Space Ordinance. As shown on Exhibit “K”, although the project does encroach into open space areas identified on the City’s “Comprehensive Open Space Network Map”, all necessary findings can be made to support this encroachment. Specifically: 1. The project encroachment (0.68 acres) will be mitigated through a project give back of 5.01 acres (a net acreage gain of 4.33 acres). 2. On an acreage basis, the replacement open space is environmentally superior to that open space which is being encroached upon, as noted below. 3. Habitat ‘Take Areas” “Give Back Areas” Coastal Sage Scrub 0168 acres 5.01 acres The proposed replacement open space areas are also located in close proximity to other existing open space areas as shown on Exhibit “I?‘. On April 25,1991, this proposed open space exchange was reviewed and unanimously approved by the City,s Open Space Advisory Committee. Local Coastal Program Planning Area 24 is located within the Mello I Local Coastal Program. When Master Plan 177 was approved by the California Coastal Commission in April of 1988, it became the implementing ordinance for this Local Coastal Program. As a condition of this approval, open space deed restrictions were placed over 248 acres of the Aviara Master Plan site. Included within these 248 acres of open space were: (1) areas containing steep slopes (25% or greater) which also possess endangered species and or Coastal Sage Scrub or Chaparral plant communities (referred to as “Dual Criteria Areas”) and (2) other areas such as Eucalyptus groves or Coastal Sage Scrub which do not meet the “Dual Criteria” but were placed in open space as mitigation for “Dual Criteria” encroachment on the Phase I hotel and Planning Area 13 sites. Both the Coastal Commission and City of Carlsbad unanimously supported this mitigation program because it resulted in the preservation of 82 additional acres of open space, over and above that which would be preserved through a strict interpretation of the existing Mello I Coastal Program “Dual Criteria” requirement. As shown on Exhibit “F”, Planning Area 24 contains 14.5 acres of coastal deed restricted area. Grading associated with the PA 24 Tentative Tract Map proposes encroachment into a total of 2.0 acres of this Coastal deed restricted acreage. This encroachment is labeled as ‘Take Area” on Exhibit “F”. This project proposes to “Give Back” 2.80 acres of non-deed restricted area as mitigation for this encroachment. A biological study of these “Take” and /L- -4 ‘MP-1;7(D)/LCPA 90-6/ L , 90-lS/HDP 90-20 - AVIARA PA 2% . MiY 29, 1991 “Give Back” areas (see Attachment “B”) concludes that the “Give Back” acreage is biologically superior habitat (a net increase of 1.21 acres of Coastal Sage Scrub). Encroachment into “Dual Criteria” habitat area has largely been avoided. Only .008 acres of the 2.01 acre encroachment meets the “Dual Criteria”. This .008 acre area (“Take Area G” as shown on Attachment “A”) is in a cut slope required for the construction of Nightshade Drive. The roadway elevation at this point, and the corresponding slope height is necessary to prevent a sump drainage condition. The City of Carlsbad and California Coastal Commission have both allowed Coastal deed restricted tradeoffs within the Aviara Master Plan provided that the tradeoff does not reduce the net acreage of deed restricted area, and the biological value is maintained. In view of the fact that this mitigation program appears to accomplish these goals, staff concludes that the project as proposed, adequately mitigates project encroachment into Coastal deed restricted areas. Other encroachment mitigation incorporated into the project includes a Habitat Enhancement Program, which revegetates 5.36 acres of manufactured slopes with native vegetation (see Exhibit “I’‘-“S’). Otherwise, in that Master Plan 177 is the implementing ordinance for this section of the Mello I Local Coastal Program, approval of this Master Plan Amendment request will ensure compliance. Because the Planning Area 24 Tentative Tract Map also either avoids, or adequately mitigates project encroachment into Coastal deed restricted habitat areas, it is also found to be in compliance with the underlying Local Coastal Program. Growth Management Ordinance The project is located in Local Facilities Management Zone 19 in the southwest quadrant. At the project dwelling unit count (118 units) the proposed project is 75 dwelling units below that allowed per Local Facilities Management Zone 19.

ENVIRONMENTAL REVIEW The Planning Director has determined that this project with the implementation of mitigation measures, will not have a significant impact on the environment and, therefore, has issued a Mitigated Negative Declaration on March 28, 1991. The environmental analysis, along with the field checks by staff, identified that because: (1) the project site has already been reviewed with the Aviara Master Plan EIR 83-2(A); (2) as proposed the project implements all recommended mitigation measures of EIR 83-2(A); (3) the lot size revisions as proposed will be compatible with surrounding existing or future uses; (4) the project will either preserve in open space or replace with comparable quality and acreage the previously coastal deed restricted habitat; and (5) the project as proposed preserves an additional 4.3 acres in open space than originally anticipated under MP 177, no significant environmental impacts are anticipated. However, mitigation measures shall be required to be implemented with this project. These include: (1) implementation of a cultural resources data recovery program at site SD1 6753; (2) full landscaping of all major manufactured slopes; (3) prohibition of grading during the Black Tailed Gnatcatcher breeding season (March 1 - June 1); (4) a requirement to deed restrict in open space all “Give Back” areas; (5) a requirement to field-stake all deed restricted areas prior to the issuance of grading permits and (6) a requirement to implement all sound attenuation measures identified in the Acoustical Analysis for P.A. 24 (Mestregreve, 1990). . ?A 4 MP:1 77(D)/LCPA 90-6/c, 90-l S/HDP 90-20 - AVIARA PA 25 MAY 29, 1991 PAGE 10 In summary, staff is recommending approval of the following: 1. Approval of MP-177(D) because the proposed land use changes and development standards revisions are consistent with the General Plan and the intent of Master Plan 177, the proposed land use changes are compatible with surrounding uses, and the proposed land uses changes will result in a balanced mix of housing within the Master Plan and City. 2. Approval of LCPA 90-6 because the LCPA is consistent with the zoning and General Plan. 3. Approval of CT 90-lS/HDP 90-20 because the project is in compliance with the Subdivision Ordinance, State Map Act, Hillside Ordinance, underlying Local Coastal Programs and Zone 19 Local Facilities Management Plan.

CDC:vd ATTACIMENT “A” JUSTIFICATION FOR HILLSIDE ORDINANCE COMPLIANCE PLANNING AREA 24 UNIT 4 AVIARA LAND ASSOCIATES P & D TECHNOLOGIES 3/21/91 JUSTIFICATIONS FOR HILLSIDE ORDINANCE COMPLIANCE: UNIT 4 PUNNING AREA 24 The following outlines the unique conditions under which Unit 4 of PA 24 has been designed. I. EXISTING GIVEN CONDITIONS: A. The subject site is an existing canyon, slightly higher in elevation at the northerly end than at the southerly end at Alga Road (Attached Exhibit 1). It is surrounded by higher land in all directions. It is shown as a single family development area on fill material in the Aviara Master Plan. B. Alga Road, an existing circulation element road, forms the western and southern boundary of the planning area. It is from Alga Road that vehicular and utility access to the site must occur. Alga Road has been constructed on a 60 foot fill in this area, across the same canyon described in paragraph IA above. C. There are existing sewer mains and storm drain lines in Alga Road, to which this site must drain. The sewer main is at elevation 232. The residential axea must be designed to sewer to this point. D. Existing City Engineering policy prohibits sewer pump stations, therefore residential elevations must be designed to gravity sewer to the point in IC above. E. The future alignment for Poinsettia Lane, a circulation element road, forms the northwest boundary of the site. F. The off-site canyon to the north (Exhibit 2) has been identified by City staff as worthy of preservation (avoid any grading disturbance) due to the occurrence of LCP dual criteria habitat. II. DESIGN ISSUES: A. The connection of the PA 24 residential local street, Nightshade Drive, (and utilities) at Alga Road must be located in the location proposed on the Tentative Map for the following reasons: 1. The intersection spacing requirements of 600 foot minimum along Alga Road from Poinsettia Lane. 2. This is the point of lowest elevation to connect to utility systems in Alga Road. The low point of connection is important to minimize the fill in unit 4. 3. This location avoids disturbance of the coastal habitat along the Alga Road frontage immediately south of the proposed Nightshade Drive access location. B. The proposed grading.of the PA 24 area is the minimum necessary to allow gravity drainage of sewage to the mains presently located in Alga Road. The alternative of further lowering this area (less fill) would produce a sump condition which would require a sewer pump station to pump the sewage to the Alga Road main. Current plans show sewer grades ranging 1.1% to 2.0%. The road grades on the Unit 4 residential cul-de-sac are the same. C. The elevation of the existing Alga Road sewer main at the point located in Paragraph IC above, elevation 232, sets the minimum elevation of the neighborhood (Exhibit 3). All residential lots (Unit 4 ) sewering to this main must be designed at an elevation higher than this point. To avoid excessive fill, however, they are designed only at a minimum (1.1% to 2.0%) higher. To access this sewer main, 28 feet of fill must occur at the Nightshade Drive access to Alga Road. D. Following the 1.1% to 2.0% utility (and pad) grade to the northerly end of the neighborhood, 50 feet of fill must occur at this northerly point. This is the minimum amount of fill possible to maintain positive sewer line slope in the area. E. As a result of the prohibition of off-site grading into the northerly canyon as was contemplated in the Master Plan (p. 164), a maximum 50 foot fill slope at the northerly property line results. Filling of this off-site canyon would avoid this slope condition. This slope is at the minimum height possible considering it is necessary for these units to sewer and drain to the Alga Road main. I This slope situation is very similar to the slope near PA 25 in the Phase II area. In this situation the 60 foot slope height at Kestrel Drive could have been reduced but it would require filling the canyon and reduction of the canyon natural open space. In this case we concurred with City Staff recommendations and the preserved open space took precedence over the slope height. The condition in Unit 4 of Planning Area 24 is a version of this same issue. The open space in the off-site canyon will be preserved. III. CONCLUSION: Section 21.95.050(c)(2) of the Hillside Ordinance allows that; “applications which propose development.... requiring grading in excess of the grading necessary to provide roadways, utilities, building foundations, parking areas or recreation areas in conformance with this chapter, shall submit for review specific written findings justifying the reasons for the excess grading, subject to the approval of the decision making body”. In conformance with this section, we offer the following applicable findings: 1. The Aviara Master Plan identifies the subject site as a development area for single family detached housing. EIR 83-2(a) reviewed this development plan and found no adverse environmental impacts associated with single family development of Unit 4 of Planning Area 24. 2. Current City Engineering Policy disallows the use of sewer pump stations. Development of the site at lower grades would necessitate the utilization of a pump station. 3. The primary determinant in the proposed design and the amount of fill required to develop the site in conformance with the Master Plan is the existing vertical location of the utilities within Alga Road, a circulation element roadway. This is a modification category identified in section 21.95.070(2) of the Hillside ordinance. 4. The proposed design allows the preservation of natural open space in two locations. Off-site to the north, the canyon is left undisturbed. Also, the Alga Road frontage south of Nightshade Drive is preserved. If these areas were not preserved, the northerly slope exceeding 30 feet in height would disappear, and the overaIl amount of fill earthwork could be reduced because access to the existing Alga Road main could occur at a more southerly, lower elevation. This is in conformance with the Hillside modification category section 21.95.070(3). 5. An additional landscape parkway (Exhibit 4) along Alga Road and Poinsettia Lane frontage serves as mitigation for any visual impacts associated with the proposed amount of grading.

A total of nine “Take” areas (decreasing open space) and eleven “Give” areas (increasing open space) were evaluated for their biological resources value and relevance to the larger open space system. The habitat type and acreage of each Take and Give area is presented in Table 1 and is shown on the accompanying map. The total acreage of Take and Give areas varies by 0.78 acre in the favor of the give back acreage. The increase in natural open space to be preserved is positive biologically based on acreage alone and is positive based on habitat type or value. The increase of sage scrub habitat protected totals 1.21 acres. A reduction of 0.43 acre of chaparral brings the balance to the 0.78 acre increase of natural open space. The increase of sage scrub is potentially beneficial to the California gnatcatcher which utilizes this habitat type in the Aviara project. The exchange of acreage does not significantly affect the design or viability of the open space system to be preserved nor does the exchange affect the previous sensitive plant evaluation for the project. I hope this assessment satisfactorily addresses any biological concerns associated with the proposed exchange. Please call me if you have any questions. $incerel y, Stephen B.

Without mitigation, rear yard observers along Alga Road would experience a worst case traffic noise level of 69.7 CNEL at Lot 1. A number of exterior living areas in the project will require mitigation to comply with the 60 CNEL exterior noise standard. Those exterior living areas which will require mitigation are listed below in Table Sl. The data used in the noise barrier analysis is shown in the Appendix.

The noise barriers shall be located at top of slope. There are no moise barriers required along Mestre Greve Associates Report #91-75 Page 2 lots 100 through 107 along Poinsettia Lane. If second story balconies are planned along Alga Road or Poinsettia Lane, balcony barriers will be needed for some units. The required balcony barrier locations and heights can be addressed in a future study when precise grading plans and architectural drawings become available. The noise barriers must have a surface density of at least 3.5 pounds per square foot, and have no openings or cracks. The noise barriers may be a wall, berm, or a combination of the two. The wall may be constructed of l/4 inch plate glass, 5/8 inch plexiglass, any masonry material, or a combination of these materials. Wood and other materials may be acceptable if properly designed as noise barriers. INTERIOR NOISE LEVELS The project must comply with the City of Carlsbad indoor noise standard. With standard construction practices in California, residential buildings achieve outdoor to indoor noise reductions of 20 to 25 dB assuming windows are closed. Homes in the project will be exposed to a maximum noise level of 68.1 CNEL at the second floor of Lot 1. A number of second floor exterior surfaces in the project will be exposed to noise levels greater than 65 CNEL, and these homes will therefore require more than 20 dB noise reduction to meet the 45 CNEL interior noise standard. Detailed engineering calculations are necessary for building attenuation requirements greater than 20 dB. A future study will be needed to address interior noise levels when precise grading plans and architectural drawings become available. MECHANICAL VENTILATION REQUIREMENTS Since the noise attenuation of a building falls to about 15 dB with windows open, any buildings within the 60 CNEL contour line will meet the 45 CNEL interior noise standard only with windows closed, therefore requiring mechanical ventilation. Mechanical ventilation will be reauired for those units listed in Table S2. Table S2 PRELIMINARY MECHANICAL VENTILATION REQUIREMENTS LOT NUMBER 102 through 118 16 1 - Mestre Greve Associates Report #9 l-75 Page 3 PRELIMINARY NOISE ANALYSIS FOR AVIARAAREA24 CITY OF CARLSBAD 1.0 INTRODUCTION The purpose of this report is to show compliance of Area 24 with the noise related “Conditions of Approval” placed on the project by the City of Carlsbad. The project calls for the development of single-family units. This report incorporates the 60 CNEL exterior noise standard recently adopted by the City of Carlsbad. The project is located in the City of Carlsbad, as shown in Exhibit 1. The project site will be impacted by traffic noise from Alga Road and Poinsettia Lane. The project is not impacted by railroad or aircraft noise. This study determines the need for any mitigation measures to meet the 60 CNEL exterior noise standard, and addresses the 45 CNEL interior noise standard required by the City of Carlsbad. Mitigation measures that would be required in order to meet 65 CNEL are also included, for comparison only. 2.0 NOISE CRITERIA The predominant rating scale now used in California for land-use compatibility assessment is the Community Nose Equivalent Level (CNEL). CNEL is a 24-hour time weighted annual average noise level based on the A-weighted decibel. A-weighting is a frequency correction that correlates overall sound pressure levels with the frequency response of the human ear. Time weighting refers to the fact that noise that occurs during certain sensitive time periods is penalized for occurring at these times. The evening time period (7 PM to 10 PM) penalizes noises by 5 dB, while nighttime (10 PM to 7 AM) noises are penalized by 10 dB. These time periods and penalties were selected to reflect peoples sensitivity to noise as a function of activity. The City of Carlsbad requires that outdoor living areas not exceed a noise level of 60 CNEL for a six-foot-tall observer located five feet within the property line. In addition, interior noise levels may not exceed 45 CNEL,. The site plan for the project (Exhibit 2) was provided by P & D Technologies (“Tentative Map for Planning Area 24, 3/11/91). 3.0 METHODOLOGY The noise levels projected in the next section of this report were computed using the Highway Noise Model published by the Federal Highway Administration (“FHWA Highway Traffic Noise Prediction Model”, FHWA-RD-77-108, December 1978). The FHWA Model uses traffic volume, vehicle mix, vehicle speed, and roadway geometry to compute the “equivalent noise level”. A computer code has been written which &:$+I Lm.Corta \ I Exhibit 1 - Vicinity Map MESTRE GREVE ASSOCIATES -- --P --- ------ - _ ,‘.\ .- . I - Mestre Greve Associates Report #9 1-75 Page 4 computes equivalent noise levels for each of the time periods used in CNEL. Weighting these noise levels and summing them results in the CNEL for the traffic projections used. CNEL contours are found by iterating over many distances until the distance to 60, 65, and 70 CNEL contours are found. Mitigation through the design and construction of a noise barrier (wall, berm, or combination wall/berm) is the most common way of alleviating traffic noise impacts. The effect of a noise barrier is critically dependent upon the geometry between the noise source, the barrier, and the observer. A noise barrier effect occurs when the “line of sight” between the noise source and the observer is penetrated by the barrier. The greater the penetration, the greater the noise reduction. The FHWA model was also used here in computerized format to determine the required barrier heights. 4.0 ROADWAY NOISE The future traffic volumes for Alga Road and Poinsettia Lane were obtained from our contour analysis prepared for the Carlsbad Noise Element, (Mestre Greve Associates, April 26, 1990). The future average daily traffic volume for Alga Road between Poinsettia Lane and Batiquitos Drive is 25,400. A vehicle speed of 40 miles per hour was utilized. A 4% roadway grade was used for Lots 108 through 118, and a 6% roadway grade was used for Lots 1 and 16. The future average daily traffic volume for Poinsettia Lane between Alga Road and El Camino Real is 29,100. A vehicle speed of 50 miles per hour was utilized. Truck mixes for each of the time periods used in the CNEL calculation are presented in Table 1. These traffic distribution estimates are based upon traffic surveys, and are considered typical for arterials in Southern California. Table 1 TRAFFIC DISTRIBUTION PER TIME OF DAY IN PERCENT OF ADT VEHICLE TYPE DAY EVENING NIGHT Automobile 75.5 1 12.57 9.34 Medium Truck 1.56 0.09 0.19 Heavy Truck 0.64 0.02 0.08 Mestre Greve Associates Report #91-75 Page 5 Using the assumptions presented above, the future noise levels were computed. The results are reported here in Table 2 in terms of distances to the 60, 65, and 70 CNEL contours. These represent the distances from the centerline of the roadway to the contour value shown. Note that the values given Table 2 do not take into account the effects of intervening topography that may affect the roadway noise exposure. Topographic effects are included in subsequent analyses to determine the actual noise exposure on the project site. In addition, these projections do not include any future vehicle noise reduction assumptions to take into account the effects of legislation requiring quieter vehicles in the future. Table 2 DISTANCE TO NOISE CONTOURS FOR FUTURE TRAFFIC CONDITIONS ROADWAY SEGMENT DISTANCE TO CNEL CONTOUR (FT) -7o- -65- -6o- Alga Road (4% grade) 46 100 215 Alga Road (6% grade) 47 101 218 Poinsettia Lane 72 155 334 The results in Table 2 and the site plan (Exhibit 2) indicate that the exterior living areas along Alga Road will be exposed to traffic noise levels in excess of 60 CNEL. Observers along Alga Road will experience a worst case traffic noise level of 69.7 CNEL at Lot 1. 5.0 EXTERIOR NOISE MITIGATION For exterior living areas which are exposed to noise levels greater than 60 CNEL some form of noise mitigation is required. An effective method of reducing the traffic noise levels to acceptable levels is with a noise barrier. Representative cross-sections along the roadway (see Appendix for analysis data) were analyzed utilizing the FHWA Model to determine the necessary noise barrier locations and heights. The results of the analysis indicate that in order to meet the 60 CNEL exterior noise standard, noise barriers are required for a number of exterior living areas facing Alga Road and one Facing Poinsettia Lane. Required noise barrier locations and heights to meet the 60 CNEL exterior noise standard are listed (in bold type) in Table 3, and shown in Exhibits 3a and 3b. For the sake of comparison, required noise barrier locations and heights to meet 65 CNEL are also listed in Table 3, and shown in Exhibits 3c and 3d.

The required balcony barrier locations and heights can be addressed in a future study when precise grading plans and architectural drawings become available.

Mestre Greve Associates Report #91-75 Page 7 6.0 INTERIOR NOISE MITIGATION The project must comply with the City of Carlsbad indoor noise standard. With standard construction practices in California, residential buildings achieve outdoor to indoor noise reductions of 20 to 25 dB assuming windows are closed. Homes in the project will be exposed to a maximum noise level of 68.1 CNEL at the second floor of Lot 1. A number of second floor exterior surfaces in the project will be exposed to noise levels greater than 65 CNEL, and these homes will therefore require more than 20 dB noise reduction to meet the 45 CNEL interior noise standard. Detailed engineering calculations are necessary for building attenuation requirements greater than 20 dB. A future study will be needed to address interior noise levels when precise grading plans and architectural drawings become available. 7.0 MECHANICAL VENTILATION REQUIREMENTS Since the noise attenuation of a building falls to about 15 dB with windows open, all buildings within the 60 CNEL contour line will meet the 45 CNEL interior noise standard only with windows closed. In order to assume that windows can remain closed to achieve this required attenuation, adequate ventilation with windows closed must be provided per Uniform Building code. This can be achieved with mechanical ventilation to provide fresh air. The system must supply two air changes per hour to each habitable room including 20% fresh make-up air obtained directly from the outside. The fresh air inlet duct will be of sound attenuating construction and shall consist of a minimum of ten feet of straight or curved duct, or six feet plus one sharp 90 degree bend. Mechanical ventilation will be reauired for those units listed in Table 4 and shown in Exhibit 4, Table 4 PRELIMINARY MECHANICAL VENTILATION REQUIREMENTS LOT NUMBER 102 through 118 16 1 L MESTREGFLEVE ASSOCIATES 4k Homes Requiring Mechanical Ventilation Exhibit 4 - Homes Requiring Mechanical Ventilation MINUTES May 29, 1991 PLANNING COMMISSION Page 12 COMMISSIONERS r hear from the Traffic Engineer because he thinks if the Traffic Engineer had a safety concern, he would have brought it up. Mr. Hofman stated that he is very sympathetic about the comment regarding two-story homes and suggests that the Planning Commission request the City Council for a Zone Code Amendment. The proposed project meets all of the ordinances and he doesn't think it should be penalized. Mr. Hofman believes there is some misconception regarding public access because the common area is open to the homeowners only, and not the general public. It would be insurable since the public has no access to the property. Regarding maintenance of the landscape, he stated that the City's landscape architect will ensure that drought sensitive landscaping will be used in the common areas. Further, Mr. Hofman stated that the homes in this project will be high end and he believes that the homeowners will be able to afford the maintenance costs. He requested approval of the project tonight, if possible. Chairman Holmes took a survey of the Commission regarding the right turn issue versus a continuance. Commissioner Erwin could support a right turn exit from A Street. Commissioner Schlehuber could also support a right turn condition. Motion was duly made, seconded, and carried to adopt Planning Commission Resolution No. 3237 approving the Conditional Negative Declaration issued by the Planning Director and adopt Planning Commission Resolution Nos. 3238, 3239, 3240, and 3241 approving CT 90-13/HDP 90-191 PUD 90-16/SUP 90-7, based on the findings and subject to the conditions contained therein, with the following changes: (1) inclusion of the staff memo dated May 29, 1991; (2) the change to Condition #6 in Resolution No. 3238 to be subject to the approval of the Planning Director; and (3) inclusion of a new condition requiring a right-turn only from A Street to El Camino Real.

The approval of a 54.6 acre/122 lot/118 dwelling unit Tentative Tract Map and Hillside Development Permit for Planning Area 24 is also being requested. The project site is located at the southeast corner of the intersection of Alga Road and future Poinsettia Lane, in Local Facilities Management Zone 19. Chris DeCerbo, Senior Planner, reviewed the background of the request and stated that the applicant is requesting approval of a Master Plan Amendment, Local Coastal Program Amendment, Tentative Tract Map, and Hillside Development Permit for Erwin Hall Holmes Noble Savary Schlehuber Schramm MINUTES May 29, 1991 PLANNING COMMISSION Planning Area 24 of the Aviara Master Plan. The site is surrounded by agricultural uses to the north and east, Alga Road to the south, and undeveloped single family residential to the west. The Tentative Map includes 118 minimum 7500 s.f. single family residential lots and four open space lots totaling 15.2 acres over the 54.61 acre site. The open space is predominately comprised of dense coastal sage and chapparal covered slopes. The northwestern corner of the planning area will be dedicated and graded for the future Poinsettia Lane. This project will have a density of 2.16 du's/ac, which is well below the site's maximum density of 3.6 du's/ac. The proposed Master Plan Amendments to Area 24 include changing permitted single family lot sizes from small lot, minimum 5000 s.f., to minimum 7500 s.f. residential lots, with development standards consistent with the R-1-7500 zone and all other current ordinances and policies, and reducing the maximum du's from 193 to 118 while increasing the open space by 4.3 acres. The staff analysis focused on the land use change from small lot, minimum 5000 s.f., to minimum 7500 s.f. lots;, and concluded that the change would have no effect on the product mix; it is, therefore, consistent with the Master Plan and General Plan goals of providing a well balanced and functional mix of residential uses. The proposed change would also ensure that development is compatible with existing and future surrounding uses and development standards would be as or more restrictive than existing standards. The project meets the requirements of the LCP, Mello I, Mello II, growth management, and all applicable ordinances. Staff recommends approval. Cornmissioner Erwin inquired if the reason grading falls below 8,000 ft. is because part of the grading has to meet the roadway. Mr. DeCerbo replied to the affirmative. That amount of fill is necessary to make the site developable. The only other deviation is a 50 ft. slope which was created to preserve a canyon where Black-tailed Gnatcatchers reside. Commissioner Erwin also noticed that side yard setbacks have been relaxed. The original requirement was 10 ft. side setbacks for (2) single story, 15 ft. for a single story and two story, and 20 ft. for (2) two stories. The R-1-7500 only requires 12 ft. side yard setbacks for two story homes, rather than 20 ft. Mr. DeCerbo replied that this was correct. However, because the lot size has been increased to a minimum of 7500 s.f., staff does not have the original concerns of a large house on a small lot. An SDP, which will contain building footprints and elevations, will be submitted to the Commission at a later date. Commissioner Erwin is concerned that with the setbacks relaxed we will now see very large homes on medium sized lots. Commissioner Hall inquired why the height was changed. Mr. DeCerbo replied that a 30 ft. measurement to the roof peak will result in an overall height reduction of the development. Commissioner Schramm inquired if the 10-15-20 ft. setbacks could be transferred from the PUD to the R-1-7500. Mr. DeCerbo replied that staff is not recommending this transfer MINUTES May 29, 1991 PLANNING COMMISSION Page 14 COMMISSIONERS Y because adequate control is built into the R-1-7500 standards. Additionally, the Master Plan requires that 15% of the du's must be one story. Also, 36 of the units will be required to have a 24 ft. setback. Staff feels this will create a quality project. Commissioner Schramm inquired if these controls will ensure that a large house will not be built on a small lot. Mr. DeCerbo replied that the development must meet the standards but there may be instances where there is a 12 ft. setback between two homes. Chairman Holmes inquired if there is any reason why the 50 ft. filled slope could not be terraced, to break up the mass. Mr. DeCerbo replied that the 50 ft. slope which was discussed is pointed north and it basically downslopes into a canyon with habitat. Chairman Holmes inquired how much of the 50 ft. slope will be seen. Mr. DeCerbo replied that we will see none of it because it faces on a canyon. It will likely be maintained in open space. Chairman Holmes opened the public testimony and issued the invitation to speak. Larry Clemens, Hillman Properties, addressed the Commission and stated that the property is located at a major intersection. The first appearance will be large lots. He noted that this request reduces the number of homes by 75 du's and, therefore, will be much lower density. Mr. Clemens stated that a considerable amount of open space has been added and there is now over four acres of open space. The front yards have been expanded to 24 ft. to create a high quality street scene. Notices were sent to everyone within 600 ft. of the project. Also, continuous neighborhood meetings have been held and there has been no response from the community, good or bad. Mr. Clemens noted that this is just one of many subdivisions which will be presented to the Commission over the next few months and is not part of Phase II. Commissioner Schraxnn inquired if the 24 ft. front yard setbacks will allow a side loaded garage. Mr. Clemens replied that it would not. Commissioner Erwin inquired if Mr. Clemens would be willing to retain the side yard setbacks which were approved previously. Mr. Clemens replied that he doesn't feel that he can because they have given up many homes by converting to R-1-7500. If they retained the old setbacks, they would be giving up twice. Cormnissioner Erwin is concerned that even though the number of homes has been reduced, the actual square footage could increase. He has seen that happen in other developments. He is concerned about the size of the house to be placed on the lot. Commissioner Hall commended Mr. Clemens about the open space pockets being shifted into one large open space element. There being no other persons desiring to address the Commission on this topic, Chairman Holmes declared the public testimony closed and opened the item for discussion among the Commission members. .- MINUTES May 29, 1991 PLANNING COMMISSION Page 15 Commissioner Schlehuber can support the project. If we want to change the R-1-7500 requirements, tonight is not the time to do it. In fairness to the applicant, he thinks the project is much better. He likes the reduced density and the increased open space. He feels it is a much better project in every way. Commissioner Schlehuber inquired when Aviara has to produce their share of low cost housing. Mr. DeCerbo replied that the low cost housing is currently under negotiation; it is required prior to recordation of the Phase II map. Commissioner Schramm inquired if the low cost housing need be on Aviara property. Mr. DeCerbo replied that this has not yet been determined. Commissioner Schramm hopes the low cost housing is spread equitably throughout the City. Coarnissioner Schraann appreciates the 15% single story but she hopes there will be considerable distance between single story and two story homes. She likes the decrease in units and the open space plan. She can support it. Commissioner Erwin would like to support the project but he has a problem with the side yard setbacks. He disagrees with Commissioner Schlehuber and will vote against the project because he feels the previous setbacks should be left in. Commissioner Noble can support the project. Commissioner Hall can support the project. He feels we often set rules and then try to squeeze for more, over and over again. The costs to a builder are immense and the prices of the homes reflect these costs. He reported that the Open Space Committee was very happy with the project because the open space was reduced from small pockets to a larger unit. Chairman Holmes agrees with Commissioner Hall. He likes the density reduction and the larger lots. He will support the project. Motion was duly made, seconded, and carried to adopt Planning Commission Resolution No. 3227 recommending approval of the Mitigated Negative Declaration issued by the Planning Director and adopt Planning Commission Resolution Nos. 3228, 3229, 32309 and 3231 recommending approval of MP-177(D)/ LCPA 90-6/CT 90-15fHDP 90-20, based on the findings and subject to the conditions contained therein. ADDED ITEMS AND REPORTS: Gary Wayne, Assistant Planning Director, reported that the Design Review appointments have been made. Planning Connnissioners Hall, Schramm, and Schlehuber will sit on the Design Review Committee. The other members will be Norby and Gonzales. Mr. Wayne also reported that because of the accelerated meeting schedule, there would probably be three sets of minutes at the June 19th meeting. Mr. Wayne reported that there is a vacancy on the Historic Preservations Committee. Chairman Holmes announced that he would like to serve on that committee. Staff will advise the City Council.
