Gaviota Creek Emergency Restoration

Project Description

Permanent Restoration

1. Scoping Phase: Permanent restoration work will complete the mitigation for the retaining wall construction in Gaviota Creek under the Gaviota Creek Emergency Scour Repair Project. The expedited Scoping Phase kicked off on October 9, 2023 and the Project Initiation Document was approved in January 2026.
2. Project Approval and Environmental Document Phase: Caltrans has determined this project is categorically exempt pursuant to CEQA Section 15333 Class 33 Small Habitat Restoration Projects.  The project size is less than five acres and is proposed to conserve, restore, protect, or enhance, and assist in the recovery of California native fish and wildlife, and the habitat upon which they depend, and to restore and provide habitat for California native fish and wildlife. The project will include a work area approximately 3.5 acres in size that includes disturbance in Gaviota Creek and surrounding riparian areas. Additionally, Caltrans has determined there would be no significant adverse impact on endangered, rare, or threatened species or their habitat; there are no hazardous materials at or around the project site that may be disturbed or removed; and the project will not result in impacts that are significant when viewed in connection with the effect of past projects, the effects of other current projects, and the effects of probable future projects.
3. Upon completion of the environmental determinations, Caltrans will move into the design phase (Plans, Specifications, and Estimates phase) to complete the design of the proposed pool and weir fishway in coordination with required agencies.

 

The objective of the restoration work is to improve fish passage and habitat conditions within Gaviota Creek. Mitigation will involve two components: fish passage remediation and habitat improvements.

Fish Passage Remediation

1. Three grade control structures exist along Gaviota Creek on the west side of US 101, adjacent to the new retaining wall that was constructed as a result of the emergency project. These structures affect migrating Steelhead trout as identified by the California Fish Passage Advisory Committee. These are priority locations to make improvements.
2. Caltrans proposes to remove the three existing grade control structures that are affecting fish passage and construct the channel to support migration of all life stages of Steelhead trout through the creek reach.
3. The design of the new fish passage system will be based on California Department of Fish and Wildlife (CDFW) and National Marine Fisheries Service (NMFS) fish passage design guidanc

Habitat Improvements

1. When completed, stream channel and bank riparian vegetation will be reestablished, and additional creek areas (as a result of removing sacked concrete) will be restored and replanted as appropriate.
