Marina Coast Water District will soon begin upgrading the water main along California Avenue between Patton Parkway and Reindollar Avenue. While construction can be disruptive we wanted to share what you can expect and how to stay informed regarding this important project that will:



👷🏻 Provide approximately 1,330 linear feet of new 12-inch water pipeline along California Avenue


👷🏻 Increase water delivery capacity, improve system reliability, and support long-term service to Central Marina


👷🏻 Help ensure dependable water service for years to come


When Work Will Occur


Start Date: Mid-March

End Date: Mid-to-late May

Work Days: Monday through Friday

Work Hours: 8:30 a.m. – 5:00 p.m.


What to Expect During Construction


Traffic Impacts

All traffic control will comply with City of Marina encroachment permit requirements and approved traffic control plans.


Traffic impacts will vary depending on the construction phase.

Drivers are encouraged to use alternate routes when feasible

Motorists should expect major delays during some active work hours


Access to Homes and Intersections

Homes along this stretch of California Avenue are back-facing, so driveway impacts are expected to be minimal. However, during pipeline tie-ins at Patton Parkway and Reindollar Avenue, there may be brief, temporary intersection restrictions. If that occurs, advance notice will be provided, and traffic control will be in place.


Noise and Dust Control

Construction activity will create temporary noise and dust. Crews will follow City of Marina requirements for dust control and permitted work hours.


Dust suppression measures

Compliance with permitted construction hours

Adherence to City construction standards and mitigation requirements


Safety Reminders


For the safety of the community and construction crews remember to:

Reduce speed in work zones

Follow posted signage

Obey traffic control personnel and flaggers


Thank you for your patience and cooperation as we work to improve the reliability of our community’s water system.

We are committed to completing this project

as safely and efficiently as possible.
