[ARCHIVED] SD2's Redwood Highway Sewer Rehabilitation Project-Larkspur

Newsflash Template (49)

A small portion of the Sanitary District No. 2 (SD2) collection network lies outside of the jurisdictional boundaries of Corte Madera in areas such as, the City of Larkspur, Town of Tiburon, and unincorporated areas such as the Greenbrae Boardwalk. As a result, SD2 often has to react quickly to expedite improvements to our collection system as we are informed of projects by other agencies.

SD2 was informed in November that the City of Larkspur planned to resurface Redwood Highway as part of their 2022 paving plan. The District created this project to rehabilitate the sewer infrastructure in advance of the roadways being resurfaced to prevent costly future repairs which would require digging into the new asphalt.

This sanitary sewer project is designed to improve efficiency and operational integrity of the sewer collection system, reduce inflow & infiltration (I&I), reduce Sanitary Sewer Overflow (SSO) risk, and reduce the need for frequent staff maintenance on the sewer system. The project will rehabilitate the sewer mains, lower private sewer laterals, and manholes on Redwood Highway from Wornum Avenue to Greenbrae Boardwalk in the City of Larkspur. The existing sewer mains consists mainly of vitrified clay pipe (VCP).
