SCH Number: 2018102017
Lead Agency: Caltrans 3 (Marysville) (California Department of Transportation, District 3)
Document Title: Bachelor Creek Culvert Replacement Project
Document Type: NEG - Negative Declaration
Received: 10/5/2018

Document Description: Caltrans proposes to replace 3 9-ft diameter x 95' long multi-plate steel culverts in the same location with two 12' x 12' x 95' long precast reinforced concrete box culverts on SR 20 in Lake County. The RCB culverts would be buried 2 ft below finished grade to provide a natural bottom through the culvert to facilitate wildlife passage. Flared wingwalls would also be installed at the inlet and outlet of the RCB culverts to connect into the existing sacked concrete rip-rap. Cable hand railings would be placed on top of the RCB culverts and along the wingwalls. Additional rock slope protection would be placed to reconstruct failing sections and to blend the wingwalls to the existing sacked concrete. The foundation below the RCB culverts may need to be excavated and replaced with suitable material.
