Walnut Creek Desilt Project Runs Through October

Accumulated sediment and other material will be removed from an area of the Walnut Creek channel in Concord starting on Monday.

Contra Costa County Public Works crews will be removing about 115,00 cubic yards of silt in the creek channel to restore flow.

Project manager Randolf Sanders said the material will fill 1,200 truckloads over 80 days. That is around 250 trips a day. Marathon Petroleum Corporation will be storing the material on their property for a future wetland rehabilitation, he said.

There will be road-side message boards and traffic redirections, but drivers near the Walnut Creek channel around Concord Avenue should consider alternative routes.

Drivers should expect delays of 5-15 minutes at Meridian Park Boulevard and Willow Way, from Via de Mercados to Concord Avenue, and Waterworld Parkway to Willow Pass Road.

Over $5 million in funding for this project is provided by Flood Control Zone 3B Funds. For more information visit: https://www.contracosta.ca.gov/8658/Walnut-Creek-Desilt.
