Lewis and lewis. Aoolicant: A request to subdivide 77 acres into eight rural residential lots on the property located at the south terminus of Blue Crystal Trail and Murel Trail, in the RR-A zone. APN: 321-270-54, 58, 59 and 63 FINDINGS The proposed project is a request to subdivide 77 acres of rural residential property of which a portion of the hillside and ridgeline area can be viewed from large segments of the valley floor. The design proposal would create eight estate-size lots, with building pads which are sited both to capture views from as high as 1320 feet and to contain large areas of contiguous natural open space. Lots 1, 2 and 3 are proposing to take access from the south terminus of the private road, Blue Crystal Trail. Lots 4 through 10 will be accessible from the south terminus of Murel Trail, which is served by Blue Crystal Trail. The lot sizes being proposed within the subject tract map will range from 13.0 acres to 9.0 acres. The building pad areas will be held to a maximum of two acres per lot. The remainder of the lots will be preserved in their natural state. Publ ic improvements related to the development of the site include the improvement of Blue Crystal Trail and Murel Trail to rural road standards and the completion of a water delivery and distribution system which will be acceptable ACTION: 2 of 24 jJ DEe 1 2 1995 ITEM 4 , Agenda Report December 12, 1995 Page 2 to the City Engineering Services Department. A comprehensive design of this system has not yet been developed. The applicants recognize the significance of this requirement and have agreed to work closely with the Engineering Department to achieve an acceptable system which will ultimately serve other adjoining properties which presently do not have City water available to them. There are design difficulties which include the elevation of some of the building pads being higher than the Blue Crystal Reservoir. ENVIRONMENTAL REVIEW An Envi ronmenta 1 Initial Study was completed for this application. It has ident i fied probabl e potent i al impacts in the areas of Soil s and Geology, Hydrology, Flora, Fauna, Transportation, Aesthetics, and Utilities and Public Services. A detailed biological assessment of the property was completed by a qualified environmental consultant. The study identified sensitive plant and animal habitat on site, including Diegan Coastal Sage Scrub and Riparian areas containing small amounts of wetland habitat. It further verified the presence of the coastal California gnatcatcher and recommended a mitigation plan to avoid siting building pads within CSS areas. For the most part the house sites are positioned within Southern Mixed Chaparral rather than within Coastal Sage Scrub and all are avoiding the locations in which the sensitive bird and animal species have been found. The report states: As currently designed, the proposed Weiss-Poway project will directly impact approximately 1.89 acres (4.1%) of Diegan coastal sage scrub, none of the mul efat scrub, herbaceous ri pari an or jurisdictional waters of the United States, 2.41 acres (11.5%) of the southern mixed chaparral, .45 acres (13.27%) of the coastal sage/chaparra 1 scrub, and 1.38 acres (34.33%) of the remaining disturbed areas. It will....indirectly impact an additional 1.77 acres (3.8%) of Diegan coastal sage scrub, and none of the mulefat, herbaceous ri pari an or jurisdictional waters of the U.S. Findings of the report maintain that the project is in compl iance with the Special 4(d) Rule Interim Coastal Sage Scrub Habitat Loss because: 1. The habitat loss does not cumulatively exceed the 5% guideline. 2. The habitat loss will not preclude or prevent connectivity between areas of high habitat value. (The applicants have agreed to annex entire subject property into the Poway Habitat Conservation Plan area and have set aside generous, connected areas of open space which will serve as-corridor areas for the movement of wildl ife as well as provide habitat for sensitive resident wildlife and plants.) 3. The habi tat loss of coastal sage scrub wi 11 not precl ude or prevent preparation of the subregional NCCP since they have become a partner in the Poway HCP. DEe 1 2 1995 ITEM 4 3 of 24 -.- -- ~- -~- --~~---- ---_._-~ ---"-"---~--'--'--~--- Agenda Report December 12, 1995 Page 3 4. The habitat loss has been minimized and mitigated to the maximum extent practicable in accordance wi th 4.3 of the adopted guidelines. The proposed mitigation replacement of 2:1 for direct impacts to the Diegan coastal sage scrub were derived based upon the high habitat value of the sage scrub on-site in addition to the conservation approach in delineating these (plant and animal) communities. 5. Habitat loss will not appreciably reduce the likelihood of survival and recovery or 1 i sted spec i es in the wild. These sensitive plants and animals have been avoided in the placement of the pad locations for future homes and accessory structures. 6. Habitat loss is incidental to an otherwise lawful activity (namely the construction of new homes). Staff recommends that the Council issue a Negative Declaration with mitigation in the areas listed as impacted. FISCAL IMPACT . Fiscal impacts will be determined at the Minor Development Review stage of this project. ADDITIONAL PUBLIC NOTIFICATION AND CORRESPONDENCE Public notice was published in the POlNay Netfs Chieftain and mailed to ....ll property owners within 500 feet of the project boundaries. RECOMMENDATION It is recommended that the City Council issue a Negative Declaration with mitigation and and approve Tentative Tract MaD 95-01, subject to the conditions contained in the attached proposed resolution.

DISCUSSION OF ENVIRONMENTAL EVALUATION (I.e. , Of affirmative answers to the above questions plus a discussion of proposed mitigation measures.) III.DETERMINATION On the basis of this initial evaluation: D I find the proposed proJect COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION wi II be prepared. @ I find that although the proposed proJect could have a significant effect on the environment, there wll I not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION Will BE PREPARED. D I find the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is reqUired.

DISCUSSION OF ENVIRONMENTAL EVALUATION 1. Soils and GeoloQv Will the proposal have significant impacts in: b,c&e. The grading required for the construction of building pads and placement of infrastructure will require the disturbance, and displacement of soils. Graded slopes will need to be protected from erosion. Erosion control devices will need to be properly maintained to prevent siltation of the blue-line stream noted in the biological assessment. 2. Hvdro 1 OQV Will the proposal have significant impacts in: b&e. There will be an incremental change in drainage patter, surface water runoff and possible danger of discharge into surface waters which constitute a part of the eastern watershed area contributing to Poway Creek. As noted in #1 above, erosion control and siltation prevention devices will need to be installed and maintained throughout the grading and installation of infrastructure processes. 4. Flora Will the proposal have significant results in: a,b&c. The focused biological study indicates that the proposed project will impact directly or indirectly approximately 3.5 acres of Diegan Coastal Sage Scrub. The replacement requirement for high quality CSS is 2:1 is mitigated on site or purchased off site within the Poway Mitigation Area. If payment for offsite mitigation is chosen, the anticipated costs are $10,000 per acre of habitat disturbed. 5. Fauna Will the proposal have significant results in: a,b,c&d The biological study identifies four sensitive animal species which are present on the property including; two San Diego horned lizards, six orangethroat whiptail lizards, two pair of coastal California gnatcatchers, and twelve southern California rufous-crowned sparrows. The graded pad for proposed Lot 7 will impact the between one-third and one-half acre of the use area for the resident California gnatcatchers. The area of disturbance is located at the extreme northeast sector of their use area. Mitigation will also require a limitation on grading during the nesting, breeding and fledging season, from February through the end of July. Fencing around home sites will be recommended to be limited to the immediate graded pad area, including any slopes planted for fire protection. The remainder of each lot should be kept in its natural state. Property owners should be required not to permit their dogs and cats from using the natural area as part of their yard area. 20 of 24 DEe 1 2 1995 I i .::..~ 4 - \ Environmental Study Checklist Page 8 9. TranSDortation Will the proposal have significant results in: a&b There will be substantial additional vehicular movement and effects on the private rural roadways serving as access to this property during installation of infrastructure improvements and grading of building pads. New street will be required to be installed and existing private roadways will be required to be improved to City rural road standards. 12. Aesthetics Will the proposal have significant results in: a,b&c The project is located on a prominent eastern hillside which is at an elevation which will make any development highly visible to the valley floor. It will be readily observable from the Town Center area as well as from the Garden Road vicinity and along segments of Twin Peaks Road. In order to reduce visual impacts graded cut and fill slopes will need to be minimized. Cut slopes should be limited to a minimum of 2:1 gradients or no taller than 25 feet and only in cases where the new home can be constructed so as to shield views of the cut. Planting of manmade slopes should be accomplished with materials which transition into native. They should be fire resistive, should be colors which blend with native plants, and should be non-invasive species if they are non-native plants. Building colors and materials should be selected with an effort to help the structures blend with that of the surrounding hillside. Shades of dark tans, grays, greens and beiges, with earthtone terra cotta tiles or flat simulated shake roofs are recommended in order to adequately mitigate potentially unacceptable visual impacts. 13. Utilities and Public Services Will the proposal have significant need for new systems, or alterations to the following: d. Water supply will be affected by this project. A determination will be made as to the method of water delivery to the subject lots. The extension of a new system of lines will be needed, and possibly a new reservoir. These improvements will be determined to the satisfaction of the Directors of Engineering and Public Services. -.
