LANDS OF KILLIAN AND LEE, 27961 CENTRAL DRIVE. (FILE #216 -06 -SD) FROM: Nicole Horvitz, Assistant Planner'/ APPROVED BY: Debbie Pedro, AICP, Planning Director '"t;e RECOMMENDATION That the Planning Commission Approve the requested Site Development Permit for the relocation of a driveway and a grading policy exception, subject to the attached conditions of approval in Attachment 1. BACKGROUND The subject property is a 2.98 -acre parcel located on the north side of Central Drive. The construction of the new residence was completed on September 1, 2006. A two story residence with a detached garage, secondary dwelling unit and pool house was approved on March 11, 2003 at a Fast Track Hearing: CODEREOUIREMENTS Per Section 10-2.301 of the Los Altos Hills Municipal Code, the construction of a driveway which results in a new or relocated access point to a public or private road requires an administrative review with a public hearing. This application has been forwarded to the Planning Commission for review because the applicant requests a Grading Policy Exception for the driveway. Specifically, the proposal includes the maximum fill depth of up to 6'. The Grading Policy (Attachment 2) is used by staff in evaluation of development projects and making recommendations to the Planning Commission and City Council. The Planning Commission has discretion to approve grading levels beyond standard requirements when the individual site dictates the need to deviate from the criteria. u1MG181,X9fi0 The current driveway access to the property is located along the south property line. The applicant is requesting to relocate the driveway access 120' east of the existing driveway to provide a better sight distance when entering onto Central Drive. The applicant is requesting a grading policy exception for 6' of fill for the new driveway, the grading policy permits up to 3' of fill. The fill material will gradually slope and blend into the Planning Commission Lends of Killian and Lee 27961 Central Drive June 7, 2007 Page 2 of 5 natural grade along the east and west sides of the driveway. The property is constrained by the steep slopes along the front of the lot. According to the applicant, the additional fill is necessary to construct a driveway with a gentler slope and provide a safer driveway for the homeowner.

The light fixture has a 60 degree back tilt with an aluminum glare shield. The lights will have a maximum wattage of 25w. The Town's Outdoor Lighting Policy (Attachment 4) states "Generally lighting shall be down shielded, low wattage, shall not encroach or reflect on adjacent properties, and the source of the lighting fixture shall not be visible from off the site. The glass on the proposed light fixtures shall have frosted or opaque covers." Staff recommends that the proposed light be replaced with a down light or a fixture with frosted or opaque covers. (Condition #6) COMMITTEE REVIEW The Environmental Design and Protection Committee provided comments on March 27, 2007 (Attachment 4) The Committee commented that because the uplights are placed in the ground and will not be seen from off site, they are acceptable for safety as long as the wattage of the lights is no greater then 25w.

GRADING POLICY CALIFORNIA Code Sections: Section 10-2.7020 of the Site Development Ordinance states that: "The amount of grading, excavation, or fill shall be the minimum necessary to accommodate proposed structures, unless grading is proposed to lower the profile of buildings." Section 10- 2.703(a) requires: "Type II foundations — step -on -contour, daylight, pole foundations, or a combination thereof — shall be used on building sites with natural slopes in excess of fourteen percent (14%)." Intent: The purpose of this policy is to outline desired criteria for grading which assure that construction retains the existing contours and basic landform of the site to the greatest extent feasible. It is also intended that the policy provide guidance for "stepping" structures down sloped hillsides, and emphasizes cut to lower the profile of structures over fill or foundation walls, which tend to raise the profile of the structure. While balanced cut and fill is desirable to minimize import or export of soil, to or from a site, it is recognized that the Town's policies and the guidelines below may encourage export as cut is generally preferred over fill. These policies are intended to be used by staff in evaluation and maldng recommendations to the Planning Commission and/or City Council regarding site development applications, and as guidance for applicants. Individual sites may dictate a need to deviate from the criteria, to the extent permitted by the Planning Commission and/or City Council. 26379 Fremont Road Los Altos Hills California 94022 650/941-7222 Fax 650/941-3160 Policy Re: Grading page 2 Policies: 1. Cuts and fills in excess of the following levels generally will be considered excessive and contrary to Town ordinances and policies to grade only to the minimum extent necessary to accommodate structures and to site structures consistent with slope contours, ie., "step down" the hill*: Cut Fill House 8'** 3' Accessory Bldg. 4' 3' Tennis Court 6' 3' Pool 4'*** 3' Driveways 4' 3' Other (decks, yards) 4' 3' * Combined depths of cut plus fill for development other than the main residence should be limited to 6 feet, except that for tennis courts cut plus fill may be permitted up to a maximum of 8 feet. ** Excludes basements meeting Code definition. *** Excludes excavation for pool. 2. The height of the lowest finished floor(s) of a structure should generally not be set in excess of three (3) feet above the existing grade, to assure that structures step with the slope. 3. Driveway cut may be increased up to a maximum of eight feet (8') for the portion of the driveway or backup area which is adjacent to a garage that has been lowered with a similar amount of cut. 4. Cut and/or fill for drainage shall be limited consistent with the guidelines set forth above for each type of structure, but shall be the minimum grading needed for drainage purposes, as determined by the City Engineer. Approved by City Council: April 2, 1997 IN h - ii w ATTACHMENT 3 ATTACHMENT t/ TOWN OF LOS ALTOS HILLS Policy Re: Outdoor Lighting Code Sections: Article 10-2.10 of the Site Development Ordinance outlines criteria for outdoor lighting. In particular, Section 10-2.1003 indicates that outdoor lighting should use "the minimum wattage lights which will safely illuminate the area" and that outdoor light sources "shall be shielded so as not to be directly visible from off-site." The Zoning and Site Development Ordinances limit lighting within the setbacks to "driveway light fixtures, limited to one fixture on each side of a driveway, for a maximum of two (2) fixtures per lot," but additional fixtures may be approved if necessary for safety. Intent: The purpose of Code provisions regarding outdoor fighting is to assure that the open and peaceful character of the Town is maintained, that adequate lighting is provided for the enjoyment of outdoor use areas, and that lighting does not intrude on the privacy of neighbors. The intent of this policy is to clarify more specifically the types and numbers of lighting fixtures that the Town feels are generally consistent with the Code provisions, but to allow flexibility for additional fighting when it is necessary for safety purposes or where it is not visible from off the site. Policy: 1. The number of lights on the exterior of a structure should be limited to providing for one light per doorway, with the exception of two lights at the main entrance, at double doors or garage doors, etc., and additional lights only where the Planning Director or Planning Commission determines they are needed for safety. 2. Pathway and driveway lighting should be restricted to low -height fixtures and should be spaced the maximum distance apart which will still provide for safe use. In order to avoid a "runway" appearance, it is recommended that lighting be placed on only one side of the driveway or walkway, or alternate from one side to the other. Recessed louvered lights are suggested for walkways and steps. 3. Generally, lighting fixtures should be shielded downlights for which the bulb is not visible from off site. Exceptions may be permitted in limited locations (entry, garage, etc.) or where the fixtures would not be visible from off site. 4. Downlighting from trees is acceptable if provided for safety or for outdoor use areas, where minimal in number, and where the bulb is not visible from off site. Outdoor Lighting 5. Uplighting of trees is generally not allowed, unless it is clearly demonstrated that the number of such lights are minimal and the glow of the uplighting would not be visible from off site. 6. Spotlights should be limited in number, and directed away from clear view of neighbors. Shielding of spotlights with shrouds or louvers is suggested. 7. High intensity discharge lighting, such as mercury vapor, high and low pressure sodium, and metal halide lighting, is prohibited. 8. Lighting in setbacks is limited to two driveway light fixtures only, for the purpose of locating and identifying the site. No lights are allowed in side or rear yard setback areas, except where determined to be necessary for safety. 9. The Planning Commission and/or staff may allow lighting different than that outlined above when the proposed outdoor lighting is determined to be necessary to safely illuminate the area, or where the size of the property and/or extensive screening will assure that lighting glow and fixtures are not visible from off site. Approved by City Council: September 30, 1997 § 10.2.901 LOS ALTOS HILLS MUNICIPAL CODE § 10-21003 not be permitted unless this screening can be accomplished without interfer- ing with the function of the stricture.
