Contra Costa County Public Works crews this week began a long-term project to remove accumulated sediment and other material from an area of the Walnut Creek channel in Concord.
The project aims to remove about 115,000 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. More information about the project can be found on the Public Works website.
