Petaluma Blvd South Water Main Replacement

Project Description

This project involves installing approximately 1,500 feet of 8-inch polyvinyl chloride (PVC) water main to replace deteriorated 4-inch cast iron water main on Petaluma Blvd. South between D Street and Mountain View Avenue. Installation of this water main will improve the pressure for fire protection in the area, as well as the reliability of this piece of aging critical infrastructure which is nearing the end of its useful life. The project also includes installation of new water services to users along the project area to meet City requirements, and new fire services for commercial buildings.

Project Manager: Dan Herrera, Senior Civil Engineer

Traffic Impact

The project will impact Petaluma Blvd South. The water main installation work will close one southbound lane in the area of construction, and water service installation will impact both southbound and northbound lanes in the immediate vicinity of the work.  All traffic restrictions will be posted for drivers with signage. Ingress and egress to homes and businesses will be maintained. Traffic control and routing measure will be implemented to maintain through traffic in the area.

Project Status

Update: December 18, 2020

The installation of the new water main on Petaluma Blvd South from D St. to F St. has been completed and tested. Operations to tie the new water main and install new services is underway. These operations require the water main and water services to be shutdown to complete the new installations. Individual water services will be interrupted during this time and should be shut off for no more than an hour at a time. This will occur during the work hours from 8:00 a.m. to 3:00 p.m. Door notices will be placed on residences and businesses affected by this shutdown at least 24 to 48 hours in advance of any water being shut off. If you have any questions or concerns, please contact the City at (707) 778-4546 to discuss.

Update: November 4, 2020

Construction is currently underway on Petaluma Blvd. South (PBS). Water main installation work is currently underway in the vicinity of PBS and E Street and will continue south for the coming weeks. In the area of work, traffic control measures will be installed to reduce traffic to two lanes (one southbound/ one northbound) and the signal at D Street and PBS has been placed into flash mode. Along the pipeline route to be installed, the contractor will be placing "no parking" signs on orange cones within 24 to 48 hours of work being done. The City would appreciate during the work hours of 7 am to 4 pm, that no parking be done on PBS where the cones have been placed. While access to driveways will be maintained throughout the project, we recommend moving vehicles out of driveways. If work is being done directly in front of a driveway, the contractor will be instructed to stop work and install steel plates to provide access, but this may take up to half an hour to complete. Please plan accordingly.

Update: October 22, 2020

The City's Contractor, Coastside Concrete and Construction, has begun preliminary work on Petaluma Blvd. South from D Street to H Street. Starting the week of October 26th, the new 8-inch water main installation from D Street to H Street will commence. The water main will be installed within the right lane of southbound traffic on the Boulevard. Traffic will be reduced to one lane in either direction in the area of construction. Traffic control measures will be implemented but plan accordingly. The water main installation work may take up to four weeks. Once this work is complete, water service installation will connect existing services to the newly installed water main.
