The County has completed these projects through funding from the S.B. 271 Grant Program, Proposition 204, Coastal Conservancy, NOAA Open Rivers, USFWS, NFWF, and County in-kind matching funds. Three additional projects are scheduled for completion in 2008 and 2009. These additional three projects will open access to approximately 7 miles of salmonid habitat.
