The property consists of 35.4 acres of which only approximately 10 acres, or about 28%, will be developed; the remaining 25± acres, approximately 72% of the site, would remain as natural open space. This development project represents approximately on-half of the development density that is allowed under growth management criteria; 55 units are allowed and 28 units are being requested or a density of 1.6 Dwelling Units per acre where 3.2 is allowed. The southern portion of the property is characterized by coast live oak woodlands and steep slopes. The development will cause no impact to the coast live oak habitat and only about four-tenths of an acre of impact to southern mixed chaparral as a result of constructing the access road into the property. Encinitas Creek, a major open space corridor under the proposed Carlsbad Habitat Management Plan (HMP) passes through the northern portion of the property. Development is being kept away from the existing wetlands with only 0.28 of an acre being directly impacted. There is adequate room onsite to mitigate this minor impact. Based on extensive survey results and field meetings with the project biologists and representatives from the City of Carlsbad, the Army Corps of Engineers, the State Fish & Game Department, and the U.S. Fish & Wildlife Service, the manufactured slopes adjacent to the wetlands (Lots 1-19) have been relocated several times from our original plan to avoid habitat impacts and to facilitate additional habitat buffer areas. The top of slope on these lots will have a fence or wall and be the southerly edge of the wetlands buffer. To achieve the habitat buffer setbacks, the alignment of "A" Street adjacent to Lots 3-7 was adjusted in a southerly direction and will require a crib type wall along the south edge of "A" Street. As a result of the sensitive wetlands habitat on the northern portion of the property and the sensitive upland habitat and steep slopes on the southern portion of the property, the access and development options for the property are limited. The only source of access to the development is Rancho Santa Fe Road, which runs along the eastern portion of the ownership. In order to properly service the project while preserving the estimated 72% open space and avoiding impact to the property's sensitive habitat areas, a variance for cul-de-sac length will be required. The project's cul-de-sac street is 1,500 lineal feet as proposed; the standard maximum length is 1,200 feet. Due to the lack of access alternatives, the larger lots, 1,000 feet of single loaded street, and the small project size, we believe this variance request is very reasonable and supportable; a separate justification for this variance is attached. Based on the not-yet-approved Shelley Property, shown as Carlsbad Tract 90-03, this project may necessitate an intersection spacing variance on Rancho Santa Fe Road; 500 feet versus the 600 foot standard. An intersection with full left and right turning movements is required for Colina Roble. In light of the project's limited frontage along Rancho Santa Fe Road and the small size of the development, we will request that the project not be required to construct planned widening and related improvements to Rancho Santa Fe Road. Instead, we will request that our project pay the required fee established for this area so that the entire section of Rancho Santa Fe Road can be improved at one time in the future. In addition to paying the proportionate share fee, we will offer to set aside a portion of the property as a mitigation area for the wetlands impact that will likely occur as a result of the widening of Rancho Santa Fe Road where it crosses Encinitas Creek. As part of the Olivenhain Road widening project, the City of Carlsbad recently completed construction of Detention Basin "D" on the northwestern portion of the property. As part of this project, we will request the City to vacate portions of the dike easements and inundation easements that the City acquired as part of the detention basin construction. The construction of Colina Roble will eliminate the need for all or portions of these City easements. The project has five panhandle lots (lots 19,22, 23, 25, and 26) which integrate well into the project's overall layout and larger lot design. A separate justification has been prepared for this request. Our project application includes a request to the Council Policy 57 and 58 Committee relative to affordable housing. Included with this transmittal is a letter from the previous housing and redevelopment director in which he recommends that this project be allowed to purchase the required affordable housing credits in the Villa Loma Project. With 28 residential units proposed, the project's affordable requirement is 4.2 units (28 x 15% = 4.2). The proposed Carlsbad Trail System Segment Number 55A has not been shown within the boundaries of this project. The siting criteria suggests that the trail could connect with the traffic signal at Olivenhain Road. In addition, Trail Segment 56A is suggested to be a sidewalk/bike lane type of a trail system. Because of the significant wetlands along the north side of Encinitas Creek and its sensitive value as a habitat corridor, it seems unlikely that this would be a good location for a public trail system. We would suggest that the public trail system be in the right-of-way on the west edge of Rancho Santa Fe Road to the City of Encinitas Boundary. Overall, we believe the proposed development responds well to the City's development criteria as well as the property's unique physical constraints while blending a high quality residential housing opportunity with an extraordinary level of natural resource protection. L-1039.042 1/9/98 STATEMENT OF AGREEMENT TENTATIVE SUBDIVISION MAP CITY OF CARLSBAD The Subdivision Map Act and the Carlsbad Municipal Code sets a fifty (50) day time restriction on Planning Commission processing of Tentative Maps and a thirty (30) day time limit for City Council action. These time limits can only be extended by the mutual concurrence of the applicant and the City. By accepting applications for Tentative Maps concurrently with applications for other approvals which are prerequisites to the map; i.e., Environmental Assessment, Environmental Impact Report, Condominium Plan, Planned Unit Development, etc., the fifty (50) day time limits and the thirty (30) day time limits are often exceeded. If you wish to have your application processed concurrently, this agreement must be signed by the applicant or his agent. If you choose not to sign the statement, the City will not accept your application for the Tentative Map until all prior necessary entitlements have been processed and approved. The undersigned understands that the processing time required by the City may exceed the time limits, therefore the undersigned agrees to extend the time limits for Planning Commission and City Council action and fully concurs with any extensions of time up to one year from the date the application was accepted as complete to properly review all of the applications.

Bentley 3573 East Sunrise Drive, #221 Tucson, AZ 85718 2. Off-site or Combined Project Name: Villa Loma 3. Description of Project with Inclusionary Housing Obligation: a 30 lot, 28 unit R-l-10,000 sq. ft. subdivision 28 x 15% = 4.2 units 4. Proposed On-site Project Description (if any): None 5. Proposed Off-site Project Description: None Description of On-stte Project Constraints: bolina Roble is a 28 unit subdivision with a minimum lot size of 10,000 sq. ft. with a 4.2 affordable unit requirement, there is no economy in scale because of the size. Also, the large lot size and significant public improvement requiremen will produce a significant price difference between any onsite affordable units and the proposed single family development. Attachment "1" to Council Policy Statement No. 57 WORKSHEET ASSESSMENT CRITERIA 1. Feasibility of the On-site Proposal. a. Are there sianificant feasibility issues due to factors such as project size, site constraints, amount and availability of required subsidy, and competition from multiple projects that make an on-site option impractical? ASSESSMENT CONCLUSION (Check appropriate box) DOES NOT SUPPORT OFF-SITE PROPOSAL INCONCLUSIVE SUPPORTS OFF-SITE PROPOSAL Brief Narrative: Yes, Although growth management calculationswould allow 55 units, because of onsite constraints, only 28 units can be achieved. 72% of the site is steep slope sensitive upland habitat or wetlands. b. Will an affordable housing product be difficult to inteqrate into the proposed market development because of significant price and product type disparity? Brief:_Narrative: Yes, the future homes will probably be in excess of 3,000 sq. ft. and be in the high $300,000 to $500,000 range. A small apartment project of four units that can rent for affordable rents ($450 to $600+) would not be compatible with the area. c. Does the on-site development entity have the capacity to deliver the proposed affordable housing on-site? Brief _Narrative: No, the applicant is a developer and not a builder and is not expirienced in the development of affordable housing. Also, the development of four affordable units does not appear to be a feasible proposal. 2. Relative Advantaqes/Disadvantaqes of the Off- site Proposal. a. Does the off-site option offer greater feasibility and cost effectiveness than the on-site alternative, particularly regarding potential local public assistance? WORKSHEET ASSESSMENT CRITERIA ASSESSMENT CONCLUSION (Check appropriate box) DOES NOT SUPPORT OFF-SITE PROPOSAL INCONCLUSIVE SUPPORTS OFF-SITE PROPOSAL Brief Narrative: Yes, Villa Loma ±5 a successful project. The applicant participation in Villa Loma would assist the City recover their investment. b. Does the off-site proposal have location advantaqes over the on-site alternative, such as proximity to jobs, schools, transportation, services; less impact on other existing developments, etc.? Brief Narrative^ Yes, Villa Loma is on El Camino Real and near the job center of Carlsbad, Affordable housing onsite would not be convienient to public services. c. Does the off-site option offer a development entity with the capacity to deliver the proposed project? Brief Narrative.^ Yes, Villa Loma is an existing successful project. d. Does the off-site option satisfy multiple developer obliqations that would be difficult to satisfy with multiple projects? Brief Narrative: Yes, one of the purposes of Villa Loma was to address this question. 3. Advancing Housing Goals and Strategy a. Does the off-site proposal advance and/or support City housing goals and policies expressed in the Housing Element, CHAS and Inclusionary Housing Ordinance? Brief Narrative^ Yes, Villa Loma has a large number of units and a diversity of affordable housing stock with its 344 units.

L-l 039.045 1/14/98 Iciduiig Design Group, Inc. JUSTIFICATION FOR A STANDARDS VARIANCE FOR INTERSECTION SPACING ON RANCHO SANTA FE ROAD FOR COLINA ROBLE Description of Standards Variance request. The developable portion of the property is only 28% of the total ownership and is in a narrow east/west band of property lying between steep slopes on the south that contain sensitive upland habitat and sensitive wetlands and floodway of Encinitas Creek on the north. The access road (Street A) intersection was located as far south as possible to not require the construction of retaining walls against steep slopes. This most southerly location is 500 feet south of proposed Avenida Aragon in the pending Shelley Tentative Map (CT 90-03). City Standards require a 600-foot intersection spacing along 84-foot wide secondary collectors (Rancho Santa Fe Road). Approval of a 100-foot reduction in intersection spacing is requested based on the following: A. Natural conditions extremely limit the location of proposed "A" Street. B. Ultimate ADT (280) contribution to Rancho Santa Fe Road is significantly under what City requirements are for cul-de-sac streets (500 ADT) - 56% of maximum. C. There is no opportunity for additional traffic on "A" Street after this project is developed. D. The proposed intersection is in an area that will exceed City standards for site distance requirements. E. The next proposed intersection to the south on the Shelley Tentative Map is 760 feet southerly of "A" Street. Based on the above, we feel the standards variance may be granted as further stated below: A. The site and conditions are extraordinary and unusual in relationship to the surrounding properties. B. The proposed street drainage system meets or exceeds City requirements. 703 Palomar flirport Road 4 Suite 300 *• Carlsbad, California 92009 (760) 438-3182 FflX (760) 438-0173 2 of 2 C. The proposed low traffic generation (280 ADT) will not cause unanticipated traffic at the intersection (Growth Management anticipated development would allow 55 units) where 28 units are being proposed. The future development of Rancho Santa Fe Road will provide full improvements so no conflict will exist with future pedestrians or bicycle use. D. The variance is minor in nature and is needed for access to the property. E. No affect can be determined on the City's Comprehensive General Plan.

The assessment has been conducted in conformance with the City of Carlsbad Planning Department's requirement that exterior noise levels not exceed 60 dB CNEL at the backyards of the homes. To mitigate the exterior noise impact to the City's noise standard, noise barriers would be required to be constructed along the rear yards of Lots 1 through 6 adjacent to Rancho Santa Fe Road. To comply with City's interior noise standard, an interior noise study will be required if two story homes are proposed to be located on Lots 1 through 6, The interior noise study will be required prior to issuance of building permits to ensure that the interior CNEL would not exceed 45 dB. ; ';:'..: 1.0 BACKGROUND Project Setting The Colina Roble project site is located in the southeast quadrant of the City of Carlsbad, west of Rancho Santa Fe Road and adjacent to the northern boundary of the City of Encinitas. The project would develop the site with 28 single family homes. This noise analysis evaluates the exterior noise level resulting from traffic along Rancho Santa Fe Road. The analysis is based on the tentative map (Ladwig Design Group 12/8/97), ' .: .'••'••._- ' . The primary noise source at the site is vehicular traffic along Rancho Santa Fe Road. Rancho Santa Fe Road is currently constructed as a two-lane road adjacent to the site. The existing traffic volume is ^ RECEIVED 0 8 133 MliW6 BESiGli 6R Mr. David Bentley January 7, .1998.. Page 2 approximately 11,260 average daily traffic (ADT) (City, of Carlsbad, 1997). City Noise Criteria The City of Carlsbad requires that exterior noise levels shall not exceed a Community Noise Equivalent Level (CNEL) of 60 dB at 20-feet from the rear/side of the structure, unless the rear/side yard is less than 20-feet deep. Where the useable rear/side yard is less than 20-feet deep, the location may be taken at the back of the useable rear/side yard, as may be approved by the Planning Director. All sound levels discussed in this report are A-weighted. Methodology The noise analysis methodology is based on the City's noise assessment methodology documented in the City's Noise Guidelines Manual (City of Carlsbad, 1995). The future noise level along Rancho Santa Fe Road was. determined based on an ambient noise measurement and using Caltrans' SOUND32 Highway Traffic Noise Prediction. Model (Caltrans, 1983). with California noise emission factors (Caltrans, 1987). The noise model is based on the Federal Highway Administration's traffic noise prediction model (FHWA, 1978). Input used in the noise model included the buildout traffic volume of 24,900 ADT (City of Carlsbad, 1997) with vehicle speeds of 45 mph along Rancho Santa Fe Road. The truck mix used was 1.83 percent medium trucks and 0.28 percent heavy trucks. The traffic mix is based on vehicle mix surveys conducted by the City. The lots would typically be located above Rancho Santa Fe Road and the intervening ground, therefore, a hard site noise propagation factor was used. 2.0 EXISTING CONDITIONS Ambient Noise Monitoring A noise measurement was conducted at the site on December 16, 1997 .to determine the existing noise level. The measurement was made using a calibrated Larson-Davis Laboratories Model 700 (S.N. 2132) digital integrating sound level meter. The sound level meter meets the current American National Standards Institute standard for a Type 1 precision sound level meter. The traffic noise measurement location was selected to provide an unobstructed view to Rancho Santa Fe Road and is depicted as Site 1 on Figure 1. Site 1 is approximately 40 feet from the existing center line of Rancho Santa Fe Road. The sound level meter was positioned at a height of approximately five feet above the ground. Concurrent traffic counts were made during the noise measurement. The measured average noise level was 67 dB. Table 1 shows the measured noise levels and the concurrent traffic volumes. . . ,^: ,a-.- Mr. David Bentley January 7, 1998 Page 4 Table! Measured Noise Level And Traffic Volumes Site 1.

Noise Modeling The existing CNEL was calculated for the noise measurement location based on the current traffic volume along Rancho Santa Fe Road using Caltrans' SOUND32 noise model. To verify the input used in the noise model, the same traffic volume and vehicle -composition ratios counted during the noise measurements were used. The modeled hourly average noise level was within one dB of the average noise level measured at the site, thereby, confirming the assumptions used in the noise model. The CNEL at the measurement site was calculated by adjusting the traffic volume and truck percentage to a set of normalized conditions (i.e., the City traffic mix and existing ADT). The existing traffic generated CNEL at Site 1 is calculated to be 70 dB. 3.0 ANALYSIS Exterior Noise Levels Rancho Santa Fe Road would be the primary noise source in the future. Residences on Lots 1 through 6 adjacent to Rancho Santa Fe Road would be exposed to a future CNEL greater than 60 dB. The closest residence adjacent to Rancho Santa Fe Road would be located on Lot 1. The first floor CNEL would be approximately 68 dB at this lot. The noise level would exceed the City's noise guideline by up to eight dB, and would result in a significant noise impact unless mitigation measures are incorporated into Mr. David Bentley January 7, 1998 PageS the project. The backyards of Lots 7 through 28 would be exposed to a future CNEL of 60 dB or less. Figure 2 depicts the future first floor noise level at the backyards of several representative lots. Interior Noise Levels The City requires that interior noise levels not exceed a.CNEL 45 dB. Typically, with the windows open, and using standard California construction materials and methods, the building shells provide approximately 15 dB of noise reduction. Therefore, homes exposed to an exterior CNEL greater than 60 dB could result in an interior CNEL greater than 45 dB. The exterior CNEL at Lots 1 through 6 would exceed 60 dB CNEL. : 4.0 MITIGATION Exterior Noise Mitigation Measures To mitigate the exterior noise impact at the homes on Lots 1 through 6 would require noise barriers ranging from five to seven-feet in height. Lots 1 and 2 would require a minimum seven-foot high noise' barrier; Lots 3 and 4 would require a minimum six-foot high noise barrier; and Lots 5 and 6 would require a minimum five-foot high noise barrier to mitigate the noise impact. The noise barriers should be constructed along the top-of-slope of the lots as depicted in Figures. , . The noise barriers may be constructed as a wall, berm or combination of both. The noise barriers must have a surface density of at least 3.5 pounds per square foot; and have no openings or cracks. The wall may be constructed of 5/8-inch plexiglas, any masonry material or a combination of these materials. The mitigation measures are based on a review of the tentative map. If changes are made to the proposed building pad elevations or lot setbacks as shown in the tentative map dated December 8, 1997, a noise study will be required to determine whether the proposed barrier heights and locations will mitigate the noise level. ''••.• Interior Noise Mitigation Measures To comply with the City's interior noise standard, an interior noise analysis will be required for the project if two story homes are proposed on Lots 1 through 6. This assumes that the exterior noise mitigation measures are implemented. If two story homes are proposed on these lots, .the interior acoustical analysis will be required for the homes on these lots prior to issuance of building permits to ensure that the interior CNEL would not exceed 45 dB. To mitigate the interior noise impact, the homes on these lots would most likely require air-conditioning and/or mechanical ventilation, and could require sound-rated windows. .:a^=.5f-- sgr IT ; ".-;•*£/.
