Funded by CALFED’s watershed program and the Proposition 13 bond measure, CCWRAP enables a comprehensive assessment of Codornices Creek’s fish habitat, and the development and initial implementation of a plan to restore the stream to health with an emphasis on salmonids. The plan, completed in 2004, identified potential barriers to fish migration and chronic erosion sites; assessed existing available habitat, and analyzed physiochemical water quality parameters. It offered restoration recommendations to restore and enhance fish and wildlife habitat throughout the entire creek corridor and create a well-defined and sustainable Codornices Creek monitoring program.
Based on the results of the CCWRAP study, UCC collaborated with hydraulic engineers, fishery biologists, city officials, regulatory agencies, and residents to develop habitat restoration and barrier remediation designs. (View hydraulic analysis and conceptual designsView hydraulic analysis and conceptual designs) Due to flooding concerns migration improvement efforts were focused on Albina Avenue. This site was identified as the limiting barrier for fish migration and a chronic erosion site degrading downstream habitat on Codornices Creek.
UCC also works with homeowners along Codornices Creek to improve habitat and create “fish-friendly backyards”. If you are an interested homeowner please contact us.
The program builds on the history of successful past restoration efforts along the lower reaches of Codornices Creek, including natural channel design, daylighting, bank stabilization, native plant revegetation, and the creation and enhancement of creekside trails.
CCWRAP is funded through Spring 2008 to implement portions of the 2004 CCWRAP report. Key program elements include:
fish population monitoring (electrofishing surveys, spawning surveys, and outmigrant trapping)
baseline water quality assessments;
outreach workshops for creek landowners and community members;
detailed stream survey mapping of the creek corridor;
bank stabilization designs for erosion sites identified in the 2004 CCWRAP;
barrier remediation designs for selected potential barriers identified in the 2004 CCWRAP;
implementation of priority restoration projects.
