This project replaced an existing concrete low-flow (Arizona) crossing and degraded culvert with a 54-foot bottomless-arched culvert on S. Refugio Road where it crosses Quiota Creek near the town of Santa Ynez (Figure 1). Engineered Streambed Material (ESM) was placed in the stream channel and configured to simulate natural stream geometry. A single lane hot-mix asphalt road surface was constructed over the top of the bottomless-arched culvert connecting the existing road surface below and above the project area. Guardrails and bridge rails were installed to meet all County safety requirements. All exposed concrete of the bridge system was given an anti-graffiti treatment. Construction work occurred within the boundary of the designated project area including all grading, excavation, filling, stockpiling, and equipment access. The project complied with all terms within the FRGP Biological Opinion and all permit conditions. The project was completed as scheduled and approved. Actual project cost exceeds proposed project cost because additional cost share was obtained from the grantee.

Project Benefit    

Increase spawning habitat and improve escape cover by removing the concrete crossing.
