Geotechnical Report As required by General Plan policies and the Specific Plan, a geotechnical analysis was prepared for the subject site entitled "Geotechnical Investigation on Proposed Residential Development Lot 27, 1630 Vineyard Ave" by Terrasearch Inc. The geotechnical report was peer reviewed by the City's consulting geologist, Mr. Alan Kropp, of Alan Kropp and Associates. Terrasearch's response to the peer review comments and Alan Kropp and Associates' final review comments are stated in letters dated March 12, and June 12, 2007, respectively, which are provided in the Planning Commission's packet. From a geotechnical engineering standpoint, Terrasearch states that the proposed development can be constructed as planned, provided that the conclusions and recommendations contained in the report are incorporated into the project design and grading. Consistent with City policy, the geotechnical report was peer reviewed by the City's consulting geologist, Mr. Alan Kropp, of Alan Kropp and Associates. In his attached letter, Mr. Kropp indicates that the geotechnical investigation preformed by Terrasearch generally conforms to accepted geotechnical/geologic principles and practices, but there are a few items that need to be reviewed as the project progresses, such as observing the grading of the estate lot to confirm that the geologic structure exposed is compatible with the recommendations made by Terrasearch. The geotechnical analysis and peer-review comments were reviewed and accepted by the City Engineer. A condition of approval has been included that requires the applicants to comply with the recommendations listed in the geotechnical reports and peer review letters. Utilities A preliminary utility plan has been included for the Commission's review. Water, storm drain, and sanitary sewer lines would be extended from existing City mains in Old Vineyard Avenue up the private road to serve the existing and new homes. The existing on-site overhead utility lines serving the existing home and all new on-site utilities required to serve the proposed development will be installed underground in a joint utility trench. Staff finds the preliminary utility plan to be acceptable. The Specific Plan states that property owners choosing to subdivide are required to connect their existing homes to the City water and sewer systems at the time that service is extended to their subdivided land. A condition of approval addresses this item. Shared Well An existing well located on the Roberts property is shared by both the Sariches and Roberts. The Specific Plan allows existing wells to be used for irrigation after City water is supplied to the existing residence. In addition, the Specific Plan indicates that partial mitigation of the PUD-32 Page - 13 - November 14, 2007
