Document Description
The North Coast County Water District (District) is improving operations in Water Service Zone 31 in the south area by installing a new pressure reducing valve (PRV) station at the intersection of Adobe Drive and Higgins Way (PRV #1) and upgrading the existing PRV station near the intersection of Avalon and Palmetto Avenue (PRV #2) in the north to meet fire flow demands in Zone 9. As part of the PRV Improvements, the valve vaults will be installed between 5 and 7 feet deep at both locations. The new PRV stations will have 6-inch, 4-inch, and 2-inch valves and pipelines within a 14-foot long by 7-foot wide pre-cast concrete utility vault. The vault will be buried between 5 and 7-feet below grade. Placement for PRV #1 will be outside of the travel way and within public right-of-way. A new segment of pipeline would also be installed to connect PRV #1 to the existing mains. Placement of PRV #2 will be adjacent to its existing location, behind the sidewalk area along Palmetto Ave. PRV #2 will be abandoned in place. The projected design inlet and outlet flows to the stations will be 2,250 gallons per minute (gpm) for peak hour demand and 1125 gpm for average day demand. The NCCWD is both the project applicant and CEQA Lead Agency.
