more in size). As required by the ordinance, each home will need to achieve a "Green Home" rating on Alameda County Waste Management Authority's "Single-Family Green Building Rating System." Grading and Drainage Although flat pads would be graded for the home sites, graded areas have been minimized to preserve the natural topography of the site and reduce tree removal. In addition, rounded landform grading techniques are used to achieve a natural transition between graded areas and existing terrain. Parallel retaining walls have been used in order to minimize large cut slopes. In sum, staff believes that the proposed grading is appropriate, but has recommended a few minor changes. First, staff recommends that the proposed grading and retaining wall along at southeastern corner of Lot I be set back at least three feet from the property line. Second, as required by the Specific Plan, the house/pad grading for Lot 2 will need to be modified so that it is set back at least 100 feet from the centerline of the intermittent drainage swale on the Brozosky property. Conditions of approval address these items. A drainage plan has not been submitted at this juncture. A condition of approval requires a drainage plan be submitted for City Council approval as part of its review of the PUD development plan. Measures to reduce stormwater runoff and pollutants from the site will need to be addressed in the drainage plan. A condition also requires that Lot 1 not drain onto the adjacent Roberts property. Geotechnical Report As required by General Plan policies and the Specific Plan, a geotechnical analysis was prepared for the subject site entitled "Design-Level Geotechnical Investigation Windy Oaks Subdivision" by Berlogar Geotechnical Consultants and is provided in the Planning Commission's packet. From a geotechnical engineering standpoint, Berlogar Geotechnical Consultants (BGC) state that the proposed development can be constructed as planned, provided that the conclusions and recommendations contained in the report are incorporated into the project design and grading. Examples of recommendations include: generally remove colluvium deposits when located in areas of proposed grading and replace it with engineered fill; implement design and construction measures to reduce the potential for expansive soils adversely impacting foundations and concrete flatwork; follow standard fill slope construction techniques; and place the future homes and other structures on either structural mat or pier and grade beam foundations. A condition of approval has been included that requires the applicant to comply with the recommendations listed in the geotechnical report. Page -15
