Public Works Project Updates

City Projects Under Construction (updated 11/22/2022)

Bon Air Road Bridge Replacement project 

Work is substantially complete with minor punch list items including storm drain pump station repairs remaining.   Replacement of check valves has been pushed to early/mid December due to material delivery delays and is still weather permitting.   The pump station is operational. The Hillview subdivision storm drain pipes are now connected and draining to the pump station.

Bon Air Road Bridge Mitigation Projects

Improvements include replacement of two public docks at Bon Air Landing Park and next to the Marin Rowing Association dock, converting the Piper Park dog park back to tidal wetlands, construction of a new dog park south of the Central Marin Police Authority building and stormwater improvements on Magnolia Avenue.  The contractor has started grading the new dog park area and will follow with fence installation. There will be several work slowdowns and stoppages due to regulatory agency permit work windows resulting in a projected completion date of spring 2024.
