Cotati's West Sierra Avenue Sewer Project To Cause Traffic Backups

COTATI, CA — Motorists should avoid West Sierra Avenue from Old Redwood Highway to Water Road between 7 a.m. and 5 p.m. starting Thursday and continuing through December, the city of Cotati advised.

A sewer replacement project will require one-way traffic control along sections of West Sierra Avenue and is anticipated to cause significant traffic backups, the city said.

Motorists are encouraged to plan ahead to use alternative routes.

West Sierra Avenue Sewer Project

The project is to replace and repair defective and undersized sewer pipes in West Sierra Avenue from Olof Street to Water Road, according to the city. In addition to repairing defective sections of sewer pipe to reduce inflow and infiltration, the project upsizes this pipeline in accordance with the recommendations of the City's Sewer Master Plan.

The project is one of many identified in the I&I Study and is prioritized over other repairs because of the City's Quick Strike road paving project scheduled for 2023.
