Bear Creek Culvert Rehabilitation Project
MND - Mitigated Negative Declaration
Caltrans proposes to repair a failing structural steel plate pipe culvert in Santa Barbara County on SR 154 at PM 21.3, 0.31 mile west of Paradise Rd. The 9-ft wide by 10-ft tall structural steel plate pipe was installed during construction of SR 154 in 1962 approx 100 ft below the highway. The proposed project involves paving the culvert invert (i.e., the lowest part, or floor, of the culvert) with a 6-in slab of Portland cement concrete and constructing a fish passage structure to remediate the barrier to fish passage created by stream scour at the culvert outlet. A temporary construction easement would be needed from the adjacent property owner in order to provide access to the culvert for equipment and personnel. Construction of an access road and creation of an equipment staging area will require tree and vegetation removal. Temporary stream diversion and dewatering operations would be necessary within Bear Creek as needed to conduct the required work in a dry streambed.
