The project will be required through the grading and building permit and construction processes to incorporate best management practices to control erosion and to prevent discharges into the City's storm drain system resulting from this development. Building Design Guidelines Guidelines The building and landscape design guidelines provide detailed and comprehensive landscape and building design standards -diagrams, photographs, and drawings - addressing materials, massing, detailing, architectural types, planting, etc., for clear guidance to future owners regarding all aspects of the designs of these homes. Staff believes that the proposed guidelines would provide a comprehensive level of detail and direction to the future homeowners regarding all aspects of the designs of their homes. While comprehensive in scope, staff has recommended changes to the design guidelines -floor area ratio, accessory structure building height, second units, etc. - which are detailed in the draft conditions of approval. The discussion of several of these changes follows. Review Procedures The guidelines also state the design review procedures for these homes. The first review stage is peer review of the design proposal provided by the Oak Grove Architectural Review Committee. After the committee has reviewed and approved the design plans, the homeowner would then submit the formal design application to the Planning Department for review by the Zoning Administrator. The neighborhoods immediately adjoining the north and west sides of the Oak Grove development would receive notice of the proposed design application. To inform the Planning Commission of the Zoning Administrator's actions, staff would use the procedures being followed with the Mariposa Ranch homes by the Callippe Golf Course. With the notification of the Zoning Administrator's action sent to the Planning Commission, staff will provide the approval letter, conditions of approval, and the plan set including colored building perspectives and building elevations. Also provided is an expanded 20-day appeal period. Development Standards Uses The 51 lots of this development will be subject to the permitted and conditional uses of the R-1 (One Family Residential) District as described under Chapter 18.32 of the Pleasanton Municipal Code.

Unlike the building setback standards of most PUD-based residential developments that reference a standard City zoning district, the building setbacks for Oak Grove are specific to this PUD-33 Page 49 of 59 June 13, 2007
