2023 Meadowsweet Trunk Sewer Rehabilitation Phase 3

The project will rehabilitate the remaining 2,840 feet of sewer trunk line from near the intersection of Meadowsweet Drive and Laurel Drive to the intersection of Meadowsweet Drive to the intersection of Tamalpais Drive and Chapman Drive. The project goal is to replace outdated sewer mains and manholes, reduce inflow and infiltration, and to continue to improve the overall function of the Sanitary District No. 2 collection system. The District will also replace all private lower sewer laterals as part of the Lower Lateral CIP Pilot Program and will also assist homeowners with upgrading their upper laterals to fully satisfy the 2018 Private Sewer Lateral Ordinance.

Project Notice

A Notice to Residents was mailed out on May 2, 2023. 


What streets are included in the CIP project? Meadowsweet Drive and Tamalpais Drive (From Meadowsweet to the intersection of Tamalpais Drive and Chapman Drive)

How do I know when work will take place in front of my home? The contractor will pass out door hangers 72 hours before work begins on a new street in the project. They will also place “No Parking” signs where work will be taking place. An example of the notification can be found here

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.

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 do not need to do any work until the Sewer District’s sewer project is complete (anticipated Winter, 2023). 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.
