Carmel Valley Manor Sewer Extension Project – Adopted Mitigated Negative Declaration – Prepared by Rincon

The project will extend sewer service to the existing Carmel Valley Manor senior living facility. The project includes the installation and operation of approximately 9,900 linear feet (LF) of 8-inch diameter polyvinyl chloride (PVC) gravity sewer main, approximately 900 LF of 6-inch diameter force main, concrete manholes, and a 250 gallon per minute wastewater pump station. From the proposed gravity-fed sewer, wastewater would be pumped by the proposed pump station into the proposed force main, discharging to the existing collection system at the west abutment of the County Bridge 500 crossing over the Carmel River on Valley Greens Drive. Wastewater would be conveyed through the existing collection system to the CAWD Water Pollution Control Plant. The wastewater pump station would be a small (approximately 1,600 square feet) fully developed municipal site, equipped with a back-up generator; new electrical service; wet well with submersible wastewater pumps; pipes, valves, etc.; electrical and communications facilities; pumps control unit; and surface improvements. These pumps would be placed underground, submerged in a wet well. A 10-foot access driveway to the pump station would be located between two existing trees.
