Laurel Grove Sewer Rehabilitation Project (Kentfield)

Laurel Grove Sewer Rehabilitation Project (Kentfield)

Project Construction:  May - October 2020

Project Summary

The RVSD collection system relies on pump stations and associated force mains to transport wastewater to the Central Marin Sanitation Agency (CMSA) treatment plant.

The Laurel Grove Sewer Rehabilitation Project will increase hydraulic capacity, reduce water infiltration and inflow, and provide needed structural rehabilitation in Laurel Grove Avenue between Makin Grade and Sir Francis Drake Blvd. The project will replace 4,370 feet of pipe and address sewer overflow and sagging pipe issues on Hanken Drive and Quisisana Drive. As of August 24:

  • The contractor has finished pipe-bursting up to Quisisana and began reconnecting laterals on 8/21. Some miscellaneous work between Cypress and Quisisana is being completed this week. Pipe-bursting activity headed north on Laurel Grove will begin the week of 8/31.
  • The contractor will return to SFD Blvd to perform pavement restoration in a few weeks. The date will be posted once it has been finalized.

Traffic volumes are lighter due COVID-19 health restrictions. Once the redesign is complete, sewer work will proceed during the day as long as traffic delays can be kept to a minimum.

Night work hours will be Sunday through Thursday from 8 p.m. to 5 a.m. The schedule is subject to revision to coordinate with the construction of the Marin County Upgrade the Drake Project. 

All other work is currently planned Monday through Friday from 8 a.m. to 5 p.m. The entire project is anticipated to be complete by the end of October 2020. Pavement restoration will meet County standards. 

All RVSD projects and work activities being conducted adhere to the District’s COVID-19 Exposure Control Plan to prepare for and, mitigate against the risk of COVID-19 exposure to the District’s office staff and field workers.

These upgrades to old or outdated system infrastructure will enhance local wastewater system reliability and efficiency.
