Project Summary


The 2016/17 Sewer Rehabilitation Projects will replace old or outdated system infrastructure and enhance local wastewater system reliability and efficiency. Construction to improve system performance during wet weather will involve rehabilitation of 42,000 linear feet (LF) of sewer pipeline and work on associated structures. The project is being completed at a cost of $9.8 million.


Within the communities of Fairfax, Larkspur, San Anselmo and the County of Marin in Ross Valley, construction will take place at various sites including but not limited to: Scenic Road (Fairfax and San Anselmo), Foothill Road, Allyn Ave, Redwood Road (Fairfax and San Anselmo), Floribel Ave, Frustruck Ave, Woodside Drive Easement, Manzanita Road, Hillside Drive, Creek Road, Sir Francis Drake Blvd and The Alameda Easement.
