Document Description
The Palm/Mann/Cypress Gravity Sewer Improvements Project (#959) (Project) site is located in the Ross Valley Sanitary District (RVSD) service area within the town of Kentfield in Marin County, California. The primary objective of this Project is to relieve hydraulic and structural deficiencies and reduce groundwater infiltration associated with aging RVSD infrastructure. The Project includes replacement of existing pipe segments via open cut removal (45 linear feet [LF]), and pipe bursting (5,451 LF). Existing pipe segments would be replaced with new polyvinyl chloride (PVC) or high-density polyethylene (HDPE) pipes. The Project also includes construction of new sanitary sewer lines via open cut trenching (1,622 LF), construction of 17 new manholes, removal and replacement of 1 existing manhole, removal of 4 existing manholes, and abandonment of 4 existing manholes. Lower laterals and property line cleanouts would be replaced at all locations.
The Project site encompasses approximately 0.3 acres and the total area disturbed would be approximately 12,200 sq ft. Depths of the excavation would vary between 3 and 10 ft based on location. Rehabilitation of all sanitary sewer mains would occur within the existing alignment. Most pipelines either fall within public rights-of-way or designated easements running through private property. For work in backyard easements, portable equipment would be used to accommodate space restrictions and minimize impact.
