American River Parkway Cordova Creek Naturalization

 

cbec provided restoration/rehabilitation design services on Cordova Creek located just off the American River Parkway in Rancho Cordova, CA.

Multiple stakeholders were involved with this project, including Regional Parks, County Departments of Water Resources, Sacramento Water Forum, Sacramento Area Flood Control Agency, the City of Rancho Cordova, Soil Born Farms, and the California Native Plant Society. cbec’s approach included three equal considerations of habitat quality, aesthetics, and functionality.

Other local-scale actions considered included reconnecting the channel to the floodplain by removing/lowering high floodplain terrace elevations, removal of ‘hard engineering’ structures (the gunite channel lining), allowing the channel ‘room to roam’ and to promote connectivity to the floodplain. The cbec team was focused on providing an ecologically sustainable solution for the creek restoration that minimized maintenance requirements over the long term. Key issues were setting back critical infrastructure from the creek, creating geomorphically stable channel designs, and locating stream access crossings and stable channel locations.

cbec additionally provided design services including coordination with Sacramento County as they moved beyond the 15% design level to create a set of construction documents for the project, address comments during the Basis of Design report review, and additional detail to describe design elements and their construction.

We performed post project aerial surveying via UAS (drone) services for this endeavor. For more information on this process see here.
