Document Description
CDFW has executed Streambed Alteration Agreement No. 1600-2016-0117-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, City of Jackson (the Permittee) as represented by Gary Ghio. The project consists of removing and replacing the French Bar Road Bridge. The existing French Bar Road Bridge is a 15-foot 8 inch wide and 32ft-2.5 inch long single span cast-in-place reinforced concrete deck on steel stringers supported on concrete abutments. The City intends to replace the existing structure with a 40-ft. long cast-in-place single span structure that will accommodate two approx. 10-feet traffic lanes, two 3-ft shoulders, a 6-ft wide sidewalk on the south side of the bridge, and a 2-ft wide standard metal bridge railing barriers on both sides of the bridge. The new bridge abutments will be realigned to provide improved hydraulic capacity through the project area. The replacement bridge will be designed to comply with the Hydraulic Design Criteria established in the Caltrans Local Procedures Manual. Road approaches will conform to the existing roadway. Sediment and debris will be removed to improve creek hydraulics. A debris and sediment terrace has formed west of the bridge due to the existing bridge geometry. The debris and sediment terrace will be removed and the creek will be restored to its approx. original geometry, decreasing potential scour and sediment releases. Rock Slop Protection (RSP) will be placed on a portion of the embankment underneath the bridge. Bio-engineered bank protection will be placed on the remainder of the creek banks. Bio-engineered bank protection and disturbed areas will be hydroseeded with native vegetation. Project constructions may require an in-stream water diversion of a portion of the SFJC. Flows would be maintained through the existing channel. Diversion methods may include the use of water pillows, rock, sandbags, sheet piling, pipes or coffer dams, or other structural methods approved by the Project Engineer and Department. A new sanitary sewer line will be installed directly under the new bridge. Installation of the sanitary sewer line will require excavation of a trench approx. 70-ft longx2.5-ft wide x 2-ft deep in the bed of the SFJC. A concrete casing will be poured around a new sewer line. The concrete casing and sanitary sewer line will result in 0.001 acre permanent impacts to SFJC. The SFJC will be restored to approx. original geometry within the project area resulting in a temporary disturbance of 0.182 acres of SFJC. The riparian community within the project area will be temporarily impacted by the restoration (0.127 ac). Disturbed areas will be hydroseeded with native vegetation.
