FROM: Cynthia Richardson, Consulting Planner APPROVED BY: Debbie Pedro, Planning Director��l RECOMMENDATION: That the Planning Commission: Approve the requested Site Development Permit, subject to the recommended conditions in Attachment 1. =61 The subject property is located on the west side of Old Page Mill Road. The property is accessed via a long panhandle. Surrounding uses include single-family homes on adjacent parcels to the east and south and Stanford Lands to the north and west. Existing development on this 10.8 acre property includes a 5,138 sq. ft. two story main residence, a swimming pool, a pool house, a bam, a yurt, two sheds, and a tennis court. A long panhandle driveway services the property. The applicant proposes to demolish an existing barn, replace one of the existing shed with a new 494 sq. ft. shed and construct a 326 sq. ft. addition to the main residence. On September 28 of 2006, the Town of Los Altos Hills entered into an agreement with the Crozier Hogle Estate to place the entire property into a Conservation Easement and Declaration of Restrictions and Covenants. The property has since been sold and the new owner Lucille Glassman wishes to make some minor alterations to the property. The restrictions require that any alterations or additions to the main house or accessory structures be subject to review and approval by the Planning Commission and City Council.

The existing improvements sit at the top of a knoll on the property. This large parcel is densely wooded with oaks and native shrubs. A drainage swale runs east to west on the property, bisecting the existing driveway from the residential improvements. The applicant is requesting approval of a Site Development Permit to construct a small 326 square foot addition on the main floor of the existing house. Additionally, a new 484 square foot shed/workshop will be constructed in the location of the existing 249 square foot shed. Interior renovations will also be made to the house. All modifications to the property meet the setback, height, floor area and development area requirements established in Title 10, Zoning and Site Development, of the Los Altos Hills Municipal Code. Main House - The addition to the main house will be located a minimum of 120' from the west property line, 280' from the north property lines, 540' from the south property line and 430' from the west property line. The maximum building height on a vertical plane is 17'5" and the maximum building height (including chimneys and appurtenances) is 24'3". Proposed exterior materials include concrete block walls, wood siding and steel windows, and a low pitch roof. New Shed/Workshop — The proposed new shed/workshop will be reconstructed in its current location. The new shed/workshop will be constructed in the same architectural style and of the same materials as the main house. The maximum height of the shed is 12'-6". Driveway & Parking The existing driveway will continue to serve the property with no substantial changes. The existing carport and garage will provide a total of three (3) covered parking spaces.

One (1) multi-trunk heritage oak tree is proposed to be removed. The subject tree is located approximately 2' away from the existing house and in the location of the proposed addition. An arborist report was submitted and reviewed for evaluation of these trees and tree protection measures. To ensure that all significant trees will be protected throughout the construction period, staff has included a condition of approval requiring that the trees within the vicinity of the construction be fenced for protection. Grading and Drainage Minimal grading (approximately 73 cubic yards) is proposed for this project. The Engineering Department has reviewed the proposed grading and concluded that it is in conformance with the Town's grading policy. The Engineering Department will review and approve the final drainage plan prior to acceptance of plans for building plan check. Final "as-built" grading and drainage will be inspected by the Engineering Department, and any deficiencies will be required to be corrected prior to final inspection. Fire Department Review The Santa Clara County Fire Department is requiring standard conditions including installation of an automatic residential fire sprinkler system throughout all portions of the building and a fire department engine driveway turnaround. The requirements are included in the conditions of approval. Committee Review The Environmental Design and Protection Committee reviewed the project and bad no recommendations.
