The project entails improvements to the OCSD water system, including replacement of a ±100,000-gallon redwood water tank with a ±100,000-gallon welded steel tank. The tank is located on OCSD-owned property ±150 feet south of Old State Highway, ±2,000 feet west of its northern intersection with State Route 101. The existing tank would be demolished and removed from the site, and the new tank would be installed in the same footprint as the existing tank. The entire tank pad would be over-excavated approximately three feet below the existing grade. Electrical equipment, supervisory control and data acquisition (SCADA), and a six-inch overflow pipe would be installed. In addition, three valves adjacent to the tank would be replaced. A PG&E power pole upslope of the tank would be replaced with a taller pole to provide adequate clearance for the power lines, and a 40-foot-tall communications tower would be constructed at the water tank site.
At the District office on Swan Road, electrical equipment and a 20-foot-tall communications tower would be constructed to support the SCADA system. A 90 KW, diesel-fired emergency generator equipped with a manual transfer switch would be acquired, and would be housed in a new cargo container outside the District office.
Four distribution valves are inoperable and would be replaced. Two of the valves are located at 120779 Highway 101 next to Hagoods Hardware Store, and the other two are located at 121390 Highway 101 next to the Orick Presbyterian Church. A Caltrans Encroachment permit would be required to replace the valves. All proposed improvements would be installed in previously disturbed areas. No trees would be removed.
