Title

Rio Vista Water Treatment Plant (RVWTP) Sewer Line Project

Description

The RVWTP Sewer Line Project (herein referred to as “proposed project” or “project”) would replace an existing eight-inch sewer line that connects the RVWTP to the local sewer system. The RVWTP’s sewer system ties into an eight-inch sewer line approximately 0.2-mile northwest of the RVWTP. This segment runs generally northwest between the RVWTP and an existing connection point to the local sewer pipeline system. The proposed pipeline would follow an existing unpaved access roadway between the RVWTP and the existing connection point to the local sewer pipeline system to avoid steep hillsides and impacts related to erosion. This new alignment would be located east of the existing alignment and is approximately 1,900 linear feet in length. The project also includes upsizing approximately 350 linear feet of an existing sewer pipeline from six inches to eight inches in diameter. This pipeline is located within internal roadways at the RVWTP. Implementation of the project will include excavation to install the new pipeline segment and replace the existing pipeline segment. The project would also pave the existing dirt access road to a width of 16 feet. The paved road would extend from a paved driveway within the RVWTP, along the existing dirt access road to an existing paved parking area at the south side of Central Park. The project would require vegetation removal, tree trimming, and tree removal along the pipeline segment, with an anticipated total of four trees to be removed.
