First, there would be an "in-house" review administered by the Oak Grove Review Board (ORGB), which would include Berger Detmer Ennis Architects and M. D. Fotheringham Landscape Architects. The review procedures are described in the guidelines. The design plans would be approved by the OGRB before being submitted to City staff for review. 2. Second, after completion of the "in-house" review, there would then be the formal design review administered by the Planning Department following the review procedures set forth in Section 18.20 of the Pleasanton Municipal Code. Having the Oak Grove Review Board administer the first stage of design review ensures compliance with the design guidelines as well as a continuity of review among the various house designs, e.g., ensuring that the individual design works well within the design ensemble of the surrounding homes. Similar procedures have been successfully implemented in the Mariposa Ranch development and the Ruby Hill development. Grading/Urban Stormwater Runoff The proposed grading plan includes the following features: Lots and streets would be located in the most geologically stable areas of the site in order to avoid landslide areas and to reduce the project's grading. Initial grading will be necessary to accommodate the public streets and the front-yard portion of the lots. The front-yard portion of the lot will then be contour-graded and "feathered" to existing terrain. ^ All grading will be primarily done to a minimum 3:1 slope banks and will feature a variety of greater slopes to match existing terrain. Remaining lot grading will be reviewed in conjunction with the site-specific building design applications. The lots would be designed to drain to the detention basins shown on the site plan to pretreat the runoff before its entry into the City's storm drain system. For some lots or portions of lots that cannot drain to the street, localized storm water pollution prevention measures are provided. Grading for the overall development, not including private lot grading, will result in approximately 620,000 cubic yards of cut and fill material being moved on the site. Of this amount, approximately 390,000 cubic yards of excess material will be stockpiled in two areas of the open space area. The remaining 290,000 cubic yards will be used as fill material for the roads. This will prevent having to off- haul the material down Hearst Drive and through the existing neighborhoods. These stockpiles will be contour graded to reflect the existing topography. ^ Private lots will be graded to balance cut and fill. Any minor excess graded material from the private lot grading would have to be off-hauled either to another building site in the Oak Grove development or down Hearst Drive. Each custom home lot builder will be required to certify the amount of off-haul. PUD-33 Page 10 of 59 June 13, 2007
