• To the extent possible, grading plans shall minimize earth-moving and site-grading. Development design shall avoid placing structures and utilities on or near the tops of slopes or in the shallow subsurface of slopes. General Residential Design Guideline (page 31) • Grading for buildings, driveways, outdoor-use areas, etc. should be compatible with existing topographic contours and minimized to preserve the natural topography of the site. a Graded slopes should utilize "rounded landform grading" techniques to achieve a natural transition between graded areas and existing terrain (see Figure IV-3). Flat graded planes and sharp angles of intersection should be avoided to reduce the visual impact of grading. a Substantial graded areas of uniform slope in hillside areas should be avoided. Cut and fill slopes should generally undulate and vary in slope gradient. A 16-foot wide private roadway is proposed at the end of the existing Silver Court. This private roadway would then continue southerly and meander between the tree driplines providing access to both lots. This private roadway would terminate on Lot 2 with a hammerhead design as it would also be served as an emergency vehicle access road. A four- to nine-foot high retaining wall would be constructed on portions of the east side of the road and a four-foot high retaining wall would be constructed portions of the west side of the road. The elevation of the road starts at 430 feet and ends at 530 feet at the hammerhead. The Silver Oaks Estates HOA in the letter states that proposed retaining wall, together with traffic noise and headlights, and residential noise from the proposed two homes, would be disruption impacts to the existing residents. The retaining wall that would be constructed on the east side (facing the existing homes on Silver Oaks Lane) would vary four to nine feet in height. The exterior color of the wall would be in earth tone to blend into the hillside and landscaping would be installed to screen the wall. It is possible to lower the wall height by breaking the wall into two or more parallel/terraced walls. However, this option would result in removal of some of the existing heritage-sized trees, which the applicants are trying to preserve. The Vineyard Avenue Corridor Specific Plan (VACSP) Land Use Plan denoted that the street to the proposed site would be a public street. The applicants propose a private road, which is designed per the requirements specified in the specific plan for private hillside streets. In order to preserve trees and minimize grading, staff is willing to support a private street. Discussion Point 2: Is the proposed private road alignment acceptable? Page - 14
