Document Description
The RVSD Woodland Area Gravity Sewer Improvement Project (Project) entails the construction and rehabilitation, within the existing alignment, of sanitary sewer mains and related appurtenances within the unincorporated community of Kent Woodlands, within the County of Marin. The Project plans to replace approximately 4,277 linear feet of existing sanitary sewer mains ranging in size from 6-inch (in.) to 8-in. of vitrified clay pipe with 8-in. to 12-in. high-density polyethylene (HDPE) pipe via pipe bursting, open cut, and jack-and-bore or directional drilling methods. In addition, work will be completed in or near Tamalpais Creek to remove the old, suspended pipes and to remove existing pipes that are exposed in the Tamalpais Creek channel. The Tamalpais Creek channel will be restored and replaced with constructed riffles. Following the completion of the constructed riffle, the equipment will be removed from the channel bed. The access route will be relandscaped and vegetated and areas of excavation will be covered with erosion-control fabric. Depths of excavation for Project implementation may range from 5 to 12 ft. The primary objective of this Project is to relieve hydraulic and structural deficiencies and reduce groundwater infiltration with aging RVSD infrastructure.
