Project Overview:

The goal of this project is to develop engineering designs for six major creek barriers with the focus of restoring steelhead passage and enhancing riparian habitat along Maria Ygnacio Creek and on a portion of Atascadero Creek at the confluence with Maria Ygnacio Creek.

There are multiple barriers to steelhead migration in this watershed, and this project addresses barriers that are ranked high to impassible throughout. These barriers were identified in the 2002 Steelhead Assessment and Recovery Opportunities in Southern Santa Barbara County. The project will develop final designs for four Santa Barbara County Public Works owned concrete grade control channels under public vehicular bridges (Hollister Ave, Cathedral Oaks Road, and Old San Marcos Road), the Union Pacific Railroad crossing, and the concrete grade control structure owned by Cachuma Operation and Maintenance Board.
