Possible Detours for Cyclists Ross Valley Sanitary District Construction Projects
MCBC recently received alerts regarding ongoing construction in the Ross Valley (which includes Marin County Bicycle Route 20 next to the Corte Madera Creek, as well as high traffic routes through Kentfield, Ross and San Anselmo. Riders using these routes should be mindful of construction, detours, vehicular traffic and other changing conditions.
Much of the infrastructure that Ross Valley Sanitary District (RVSD) operates and maintains to collect, pump and transport approximately four million gallons of wastewater per day is old or outdated. RVSD is working to rehabilitate underground wastewater pipelines through a construction program that is spread out over more than 34 miles of road and easements throughout Ross Valley.
If you are planning on riding in these areas, please take a moment to review the specific project pages below:
Kentfield Pump Station 15 Improvements
- Impacts Marin County Bicycle Route 20 next to the Corte Madera Creek
Once the contractor is ready to deliver and install the new pump station equipment, several pickup trucks will arrive and depart each day along Marin County Bicycle Route 20. Trucks will enter from Bon Air Road and travel along Corte Madera Creek to the Pump Station.
Please expect noise, dust, partial bike lane closures and travel delays near the work site during construction activity. All construction equipment and materials will be stored within the fenced area surrounding the Pump Station. Local emergency access will be maintained at all times. RVSD Project page
Ross Common / Upper Shady Lane Sewer Improvements
- Impacts downtown Ross, and north end of Shady Lane near San Anselmo
The Upper Shady Lane and Ross Common Sewer Improvements will replace old or outdated system infrastructure and enhance local wastewater system reliability and efficiency.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 2,300 linear feet (LF) of sewer pipeline ranging in size from 8 to 28 inches in diameter and associated structures.
Work will take place within two project areas located in the Town of Ross: the Bolinas Ave/Upper Shady Lane area (Upper Shady) and the Lagunitas Ave/Ross Common (Ross Common). RSVD Project Page.
San Anselmo (Nokomis and Meadowcroft) Sewer Improvements
- Impacts Morningside and Brookside neighborhoods
San Anselmo (Nokomis and Meadowcroft) Sewer Improvements will replace old or outdated system infrastructure and enhance local wastewater system reliability and efficiency.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 3,300 linear feet (LF) of sewer pipeline ranging in size from 18 to 24 inches in diameter and work on associated structures.
RVSD, Marin Municipal Water District (MMWD), the Town of San Anselmo and Marin County are coordinating to reduce construction impacts from other projects in the Morningside and Brookside neighborhoods this summer. MMWD is replacing waterlines on Butterfield Rd. from Sir Francis Drake Blvd. to Kenrick Ave. RVSD plans to follow with sewer construction on Butterfield Rd. in summer 2019 and summer 2020.
These projects will rehabilitate critical water and sewer infrastructure and add an easterly sidewalk from Sir Francis Drake Blvd. to Brookside Elementary School, provide road sealing from Sir Francis Drake Blvd. to Kenrick Ave., and widen a narrow section of The Alameda to provide a safer route and enhance fire and police access.
Continued Projects as Part of the RVSD Rehabilitation Projects (began 2016)
Other ongoing 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.
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.
