Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2019-0974-R1, pursuant to Section 1602 of the Fish and Game Code to Howard Dashiell, representing Mendocino County Department of Transportation. The project is limited to one encroachment. It replaces an undersized and failing culvert with a culvert of the same size. Both the current best guidance and field measurements by CDFW staff recommend a culvert diameter of 96 inches or greater for this site, however the project design engineering is for a 72-inch diameter culvert. Large concrete retaining walls at both the inlet and outlet will be anchored below the culvert grade. An additional section of bank, approximately 15 feet in length, will be stabilized with rock slope protection. Boulders for energy dissipation will be placed below the culvert outlet.
