Low Gap Road at Milepost 19.24 Culvert Replacement

Mendocino County is seeking a contractor for the Low Gap Road at Milepost 19.24 Culvert Replacement project in Ukiah, California. The project aims to address damage caused by heavy rains and mudslides by replacing a failed pipe with a larger culvert capable of handling 100-year storm event peak flows. Key technical requirements include realigning the pipe to match the natural channel, installing compacted fill to restore the shoulder, adding rock slope protection to stabilize the outlet gully, and implementing an energy dissipator to prevent streambed erosion. Construction is scheduled to take place during the dry season to ensure the project stream is dry, with heavy equipment operating primarily from the roadway and shoulders. The project will incorporate strict water quality, biological resource, and erosion control measures to protect the environment. This infrastructure improvement is designed to benefit the traveling public by restoring road stability and improving drainage capacity.
