East Blithedale Rehabilitation Project
Project Update (November 2022)
East Blithedale Avenue is now open to through traffic between Camino Alto and Downtown Mill Valley. Motorists may experience localized closures or flagged one-way traffic control until May 2023. We encourage motorists to use Miller Avenue to access Downtown Mill Valley.
Crews continue working on East Blithedale Avenue between Sunnyside Avenue and Amicita Avenue to allow for ongoing improvements with sanitary sewer, storm drainage, and concrete work, which involves replacing curb ramps, curbs, gutters, sidewalks, and driveways. We appreciate your continued patience as work continues to progress!
Sycamore Avenue Pavement Rehabilitation:
East Blithedale Rehabilitation Phase 2 (Mesa Avenue):
- Work crews will continue concrete work at Mesa Avenue and East Blithedale Avenue. Flaggers will conduct one-way traffic control. Pedestrians may use the south side sidewalk.
East Blithedale Rehabilitation Phase 3 (Hill Street to Elm Avenue (west):
- Work crews will continue concrete work along the north side of East Blithedale Avenue. Storm drain system improvements will continue between Mountain View Avenue and Grove Street.
- Motorists should expect minor delays with flagged one-way traffic control. Bus riders should be aware that bus stop 40139 at Mountain View Avenue will be out of service. Nearby stops can be found here.
Sanitary Sewer Rehabilitation Phase 3 (Sunnyside Avenue to Millwood Street):
- Work crews will install cured-in-place-pipe (CIPP) lining the week of November 14th. This is a trenchless rehabilitation and restoration method used to repair existing pipes.
- During the installation, residents near the work will notice a chemical odor. This is the smell of styrene, a component of the resin used to saturate the sewer liner. This odor will quickly dissipate once the installation process is complete.
- Sewer laterals to the residents will not be closed during the installation.
What you can do:
- Before Sewer CIPP Work Begins: Pour a gallon of water into sinks, floor drains, or other drainage openings, especially those that are seldom used and whose traps may be empty of water. This should prevent any odor from entering your building or home.
- During Sewer CIPP Work: Limit activities that use large volumes of water, such as doing laundry, dishwashing, flushing toilets and bathing. If you do detect an odor, simply open your windows and/or turn on a fan to help ventilate the building. This level of concentration of airborne styrene does not pose a health risk.
