Laytonville Dos Rios Road MP 3.91 Culvert Replacement Project (Project) Notification of Lake or Streambed Alteration, No. EPIMS-MEN-65029-R1C

The California Department of Fish and Wildlife has authorized a lake and streambed alteration agreement under Section 1602 of the Fish and Game Code to Howard Dashiell, Director of the Mendocino County Department of Transportation, for the replacement of a damaged culvert along Dos Rios Road at Milepost 3.91 near Laytonville. This single encroachment project responds to infrastructure damage caused by 2023 storm events and involves the removal of the existing culvert, excavation, installation of a new properly sized culvert, replacement of the upstream concrete headwall, rock armoring of the outlet, backfilling and compaction of fill, and repaving of the road surface. The work is limited in scope and specifically targets the repair of a single structure to restore safe passage and prevent further environmental disruption. The agreement is formally documented under EPIMS Notification No. EPIMS-MEN-65029-R1C and was posted on June 17, 2026, as a forecasted action. The project is situated in Mendocino County, California, within the jurisdiction of the California Department of Fish and Wildlife’s Region 1 Northern Region based in Redding and Eureka. Primary contact for regulatory matters is Jennifer Garrison, Senior Environmental Scientist Specialist, who can be reached through the provided phone and email. Howard Dashiell serves as the point of contact for the county department, ensuring coordination between state environmental requirements and local infrastructure needs. The project does not involve a formal solicitation or set-aside and is proceeding under the state’s authority to manage streambed alterations impacting fish and wildlife resources.
