Document Description
The proposed project is located along State Route (SR) 1 in Sonoma County, California, from post mile (PM) 30.8 to 40.6. The scope of the project is to replace 23 existing damaged or failed culverts (from south to north) between Mill Gulch and 0.5 mile south of Miller Creek. The purpose of the project is to preserve the structural integrity of SR 1 within the project corridor and to prevent localized highway failures. The project is needed to replace 23 existing damaged or failed culverts that were determined to have deficiencies and require replacement to prevent further damage and possible failure of the highway. Addressing these deficiencies would prevent failure of the culverts and undermining of SR 1 or localized flooding and would avoid impacts to the safety of the traveling public.
