The FY 2023-2024 Gravity Sewer Improvements Project (GSIP) will rehabilitate approximately 15,600 linear feet (LF) of sewer pipeline ranging from 4 to 14 inches at various locations throughout the San Anselmo, Greenbrae, and Fairfax jurisdiction. Approximately 3,060 LF will be constructed via open cut and 12,540 LF via pipe bursting. 40 new manholes will also be constructed at various locations throughout the project. New manhole locations will require excavation and backfill of an area of approximately 8 feet by 8 feet, with varying depths. Most of these pipelines either fall within public right of way or in designated easements running through private property. For work in backyard easements, portable equipment will be used due to space restrictions and to minimize impact. The purpose of the rehabilitation portion of the project is to reduce the risk of sanitary sewer spills. This will be accomplished both by fixing defects that could cause overflows as well as sealing leaks, thus reducing wet weather inflow and infiltration.
Construction is anticipated to begin in January 2024.
As with any construction project, you can expect noise, dust, some traffic lane closures and detours, parking restrictions, travel delays, and in some cases night-time work near the work sites during construction activity. We work to ensure that mail and package delivery to construction areas is not interrupted and that local and emergency access is maintained at all times.
RVSD appreciates your patience as we fulfill our commitment to making strategic long-term infrastructure improvements!
