Noise 49. The OTFAG shall indicate that homes sited on noise-impacted lots shall be designed to shield the rear yard areas from freeway noise, and that solid fencing may be permitted in very limited areas of the rear yard area of these lots (i.e. around pool and patio areas ONLY), but said solid fencing shall be screened with landscaping. Solid fencing shall consist of unpainted wood (Modification of MM 8a) 50. Mechanical ventilation should be provided for homes to allow windows to be closed to achieve indoor noise levels. Only windows facing the freeway would need to be closed to achieve the General Plan indoor noise goal of 45 Ldn. (MM 8b) 51. Homes located on hillside sites, particularly Lots 61 - 65, and those along Foothill Road shall make use of construction techniques to ensure that noise levels inside the home meet city of Pleasanton standards. Such lots should be identified in the project architectural design guidelines. (MM 8c) Geology, Soils, Grading and Drainage 52. Prior to submittal of a tentative map, the developer shall submit detailed geotechnical studies which determine all dimensions of the berm and catchment areas near Lots 1, 2 and 5. These areas shall be delineated on the tentative map preliminary grading plan. If the city determines that the deflection berm and catchment area cannot provide adequate risk-protection under the city's Safety Element "acceptable risk" policy, then the at- risk lots must be eliminated from the plan. 53. Prior to submittal of a tentative map, the applicant shall prepare detailed geotechnical studies to determine the final landslide repair measures necessary to assure development of the project as approved. If the landslide repair measures extend beyond those anticipated in the geotechnical studies prepared to date (July 30, 1991) and as shown on the landslide buttress plan (Figure 9-3, Chapter 9 of the SEIR), the Planning commission may elect to require elimination of those lots whose creation would require landslide repair measures which the Planning commission determines would have adverse impacts visual, grading, drainage and vegetative etc., on the environment. The Planning commission may make this decision when it considers the tentative map approval for this project. 54. A comprehensive and thorough slope stability investigation is required. Prior to the Tentative Map approval and issuance of a grading permit for the subdivision, all landslides and areas with a high potential for slope instability should be identified, mapped and categorized as to their potential effect on the development. The project's geotechnical engineer and/or certified engineering geologist should provide recommendations for stabilization of the areas identified. The identified areas
