Cecchetti Road Storm Repair

The proposed project would replace the previously washed out Corrugated Metal Pipe (CMP) crossing with a Bridge Concrete Arch System to improve the Cecchetti Road crossing. The previous structure was a detriment to fish passage and required periodic maintenance of debris removal which also limited fish passage. The new bridge crossing would allow for a natural channel bottom and eliminate the velocity barrier and sediment deposition caused by the previous crossing. The benefits of this structure include clear spans and unrestrictive channels, long structure lifespan, and fast installation limiting temporary project impacts.


Project Location

The Cecchetti Road crossing is located approximately 8 miles upstream of Arroyo Grande Creek confluence with the Pacific Ocean and 5 miles downstream of Lopez Dam. It is surrounded by agriculture on all sides. It is located in County right of way just outside the City of Arroyo Grande.


Project Schedule

The County Board of Supervisors approved a design contract in December 2024 with the engineering firm Consor to design a new crossing at this location. The County anticipates that the design documents will be sufficiently developed to submit to the environmental regulating agencies for approval by the end of 2025. Environmental permitting and review can take up to a year to issue the required environmental permits, especially given the complexities of the Arroyo Grande Creek. Construction is therefore anticipated to occur in the early part of 2027.
