After taking testimony, the Commission voted unanimously to recommend approval of nine lots with modified conditions. The major consideration in the Commission's review of the project concerned the subdivision layout and grading of the site. The Commission determined there was no justification for placing the existing knoll on the property within a scenic easement therefore modifying the subdivision layout. Lots 5, 6 and 7 were redesigned for two lots to !obtain more consistency with the adjacent properties to the east and south. Staff had recommended grading of the site be minimized to greatest extent possible by avoiding angular pads and constructing homes with the topography (i.e. , step-on-grade) . The Commission modified staff's recommendation conditioning the project to be a balance of cut and fill giving some consideration to minimal grading, with final review by the Zoning Administrator. ADDENDUM TO ITEM D.3 OCTOBER 6, 1992 On September 15, 1992, the Board of Supervisors deferred to this date the decision on the recommendation of the San Ramon Valley Regional Planning Commission on the request (2976-RZ) by DeBolt civil Engineering (applicant) and Walt Foskett (owner) to rezone 5.84 acres from Single Family Residential (R-40) to Planned Unit District (P-1) with a preliminary development plan, for final development plan approval for ten residential units (3038-91).. and for vesting tentative map approval to subdivide 5.84 acres into ten lots (Subdivision 7725); and also to consider the establishment of a 15-toot hiking and bicycling trail to connect Fairdale Way with the Trotter Way/l.ivorna intersection. A segment of that trail is proposed to align with the eastern boundary of the subject Foskett property in the Alamo area. On the recommendation ol'Supervisor Schroder, IT IS BY THE BOARD ORDERED that recommendations 1; 2 with amended conditions, 3 with amended conditions, 4, 5, and 6 are APPROVED; and Ordinance No. 92-70, giving effect to the rezoning, is INTRODUCED, reading waived, and October 20, 1992, is set for adoption of same.

All excavated material shall be disposed of off-site by the developer at his cost. The site selection, land rights, and construction staking will be by the Flood Control District. OR.... 2) Upon written request, the applicant may make a cash payment in lieu of actual excavation and removal of material from San Ramon Creek. The cash payment will be calculated at the rate of 50.10 per square foot of new impervious surface area created by the development. The added impervious surface area created by the development will be based on the Flood Control District's standard impervious surface area ordinance. The Flood Control District will use these funds to work on San Ramon Creek annually. 8. G. Mitigate the impact of the additional storm water run-off from this development on Miranda Creek by contributing to the County Deficiency Trust Fund a drainage fee of $0.10 per square foot of impervious surface area created by the development.
