Additional Stora~e Volume in the Vineyard Hills Reservoir The City completed a Water Master Plan in November, 2004. This Master Plan is the most comprehensive analysis of the City's water system completed to-date, and was the first plan to review the existing and required facilities within the City's Bonde Pressure Zone in detail. The Bonde Pressure Zone has the second largest water demand in the City, (the highest demand area is the City's "Lower" pressure zone that comprises much of the valley floor portions of the City. The "service" elevations of the' Bonde Zone are generally between elevations 390' and 540' above mean sea level (AMSL). As part of the Master Plan, the analysis of the Bonde Zone determined that the storage deficit in the Bonde Zone at build-out of the Vineyard Corridor, is one million gallons. The Plan also noted that there was a storage deficit of approximately an additional 400,000 gallons in the eastern portion of the Bonde Zone (generally in the Ruby Hill area) at build-out conditions . In order to offset this deficit, City staff and the Water Master Plan consultant recommended, during the preliminary engineering phase of the water facilities project, that this storage deficit be addressed within the new Vineyard Hills reservoir, since the Vineyard Corridor and Ruby Hill areas of the Bonde Zone will be connected and operate hydraulically similar. Vineyard Hills Reservoir Site Acquisition on the Reznick Partnership (Threehand L.P.) Property In order to serve the Bonde water pressure zone, the Vineyard Hills reservoir must be situated at an elevation of 636 feet above sea level. The new reservoir is proposed to be located within the Vineyard Avenue Corridor Specific Plan Area that is in the eastern half of the City's "Bonde" water pressure zone. The final site selected for the reservoir is on the Reznick (Threehand L.P.) property, approximately 2000 feet southerly of what was Vineyard Avenue. The proposed 1.4 million gallon pre-stressed concrete, partially-buried, water reservoir will be located on the southerly portion of a 20-acre parcel owned by the Reznick partnership. The new reservoir floor is located at elevation 636 feet and 2/3 of the reservoir will be buried in a natural knoll located on the southernmost portion of the Reznick partnership property. The reservoir is approximately 110 feet in diameter and 26 feet high. Access to the reservoir will be generally along a 1900-foot long access road that follows much of the existing road on the property used to access an existing dwelling. In negotiations with the Reznick partnership for the acquisition of property necessary for the construction of the reservoir and access road, Mr. Reznick expressed a desire to have the required tank access road provide all utilities to accommodate the future residential development of the property in exchange for the City obtaining the required land to construct the reservoir. (The Vineyard Corridor Specific Plan had identified six new lots, as well as the existing dwelling, as potential development on the Reznick property.) SR 06:152 Page 4 of 13
