This application is for Building Site, Grading and Design Review approval for the development of a new single-family residence, barn and riding arena, on a 20-acre parcel. The application includes the construction of the single-family residence at the crest of a hilltop, accessed by an approximately 2,000 foot-long driveway with fire truck turnouts and turnarounds. The barn and riding arena are proposed in a saddle east of the proposed building site. Anticipated grading quantities associated with the building pad for the residence, driveway and fire truck turnarounds, arena and barn are 8,858 cubic yards of total cut and 8,858 cubic yards of fill totaling 17,716 cubic yards. This includes the use of Hilfiker steepened slope retaining walls along the driveways. The slope of the Hilfiker walls will be reinforced at a 1:1 and 2:1 slope on the downhill sides. The anticipated size of the single-family house is approximately 4,000 square feet and one-story. The barn is 3,600 square feet and the riding arena is approximately 16,200 square feet. The average slope of the property is 37.8%. However, portions of the proposed driveway occurs on terrain that has an approximate 60% slope, which is proposed to be graded to meet the Fire Marshal's standards for driveway access. Eighteen Oak trees are proposed to be removed in the application. The site is located in unincorporated Santa Clara County in southwestern Santa Clara County. The property would be served by an on-site well and septic system. Staff has determined that the proposed improvements are inconsistent with the County Grading Findings and General plan Policies regarding viewshed protection. As such, site design changes have been included as conditions and mitigation measures in an effort to achieve compliance with the County General Plan policies and Grading Ordinance findings. These include shifting the footprint of the house improvements off the top of the hill, avoiding the fill of a drainage swale and maintaining a development envelope.
