Waterways has prepared multiple concept level design alternatives for each of the barriers and is awaiting the selection of a preferred alternative by project stakeholders prior to preparing 50% level designs.
Gaviota Creek Fish Passage Improvements
Client: South Coast Habitat Restoration
Waterways was retained by South Coast Habitat Restoration to prepare designs for improving fish passage at five barriers along Gaviota Creek. The sites are located north of Gaviota and directly adjacent to Highway 101. Each barrier is composed of a concrete grade control structure, originally installed to keep the creek from undermining Highway 101. Design concepts range from structural modification of individual weirs to complete removal and channel realignment.
