Document Description
Ross Valley Sanitary District (RVSD) is proposing a project to replace an existing 10-inch sewer line under Larkspur Creek with a new 18-inch sewer line. The project involves installation of the new pipe via open-cut trench methods, installation of coffer dams both upstream and downstream the site and reinstallation of the new 18-inch pipe approximately 3 feet below the streambed of Larkspur Creek. The project also involves removal of existing concrete pillows from within the stream channel in order to eliminate obstruction(s) to flow and potential fish passage concerns. RVSD has proposed to back fill the trench with low density concrete to one foot above the pipe and backfill the remaining two feet with native materials. The contractor will be required to replant disturbed stream bank areas with native vegetation as part of the proposed project. The California Department of Fish and Game is issuing Streambed Alteration Agreement Number 1600-2008-0235-3 pursuant to Fish and Game Code Section 1602, to the Applicant, Mr. Eric Stassevitch, Ross Valley Sanitary District.
