2021 Sewer Rehabilitation Project

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 existing sewer mains consists of vitrified clay pipe (VCP), polyvinyl chloride (PVC), and asbestos cement (AC) pipes.

The sewer projects will include the following roads:

  • El Camino Drive
  • Estrada Lane
  • Paloma Drive
  • Granada Drive
  • Sonora Way
  • Endeavor Drive (Granada Drive to End)
  • Endeavor Cove

The project will replace 3,400 linear feet of sewer main, 46 spot repairs, and a rehabilitation of 33 manholes. The total number of lower laterals that will be replaced with this project is 212.


Schedule updated as of February 16, 2022. This schedule is subject to change based off weather and construction delays. For specific questions, please contact the project inspector Grant Groshans at (925) 413-2547.

Frequently Asked Questions

When do I need to pressure test and/or replace my upper lateral?
Per the notification letter sent to all addresses that are part of the CIP project, homeowners may not begin any work on their upper sewer lateral until the Sewer District’s project is complete (anticipated spring 2022). Once the project is complete, the District will send a follow up letter to all residents giving 180 days to pressure test, and if necessary, replace their upper lateral.

I replaced my sewer lateral last year, am I still triggered by the sewer lateral ordinance?
If you replaced your entire sewer lateral within the last 3 years, you should have received a certificate of compliance which means you are exempt from Sewer Lateral Ordinance triggers including CIP projects. If you replaced all of or a portion of your lateral more than 3 years ago, you will still need to pressure test the lateral.

How do I know when work will take place in front of my home?
The contractor will install changeable message boards in the neighborhood when the project is about to begin showing the start date. They will also pass out door hangers 72 hours before work begins on a new street in the project and place “No Parking” signs where work will be taking place.

Will the contractor close my road so I will not have access to my home?
No, the contractor is required to keep access open to the neighborhood at all times with minor traffic delays. Emergency vehicles will always have access through the work site. On some streets they may have closures to through traffic and a detour, while on other streets with no alternate route, they will leave one lane of traffic open and have alternating traffic control.

Will I have access to my driveway during working hours?
The contractor will do their best to keep access open to all driveways during working hours Monday – Friday, 8:00am to 5:00pm. There may be some points where they must work directly in front of a driveway and providing access will take some time. Please speak with the contractor’s staff to coordinate access to your home.

Will the contractor shut off my sewer service?
No, the contractor will knock on your door and request you do not use any appliances that use a lot of water before work begins, but your sewer service will not be completely shut off. Typically, the lower sewer lateral replacement takes one day. 

Is there a list of contractors I can choose from?
Yes, the Sanitary District No. 2 keeps a list of qualified contractors which can be found here: https://www.townofcortemadera.org/DocumentCenter/View/3807/Pre-Qualified-Contractor-List-For-Public

Where can I find more information on the 2018 Private Sewer Lateral Ordinance and available grants?
