American River Watershed Project, Folsom Dam Raise, Folsom Bridge
SIR - Supplemental EIR
Present Land Use
Recreation / Flood Control / Industrial / Utility Corridor
The Folsom Bridge Project is part of the Folsom Dam Raise Project, a component of the American River Watershed Long-Term Project. The main feature of the Dam Raise Project is to raise Folsom Dam to increase the flook storage capacity behind the dam. Construction associated with raising the dam along with other flood control features could take up to 20 years to complete. This work would result in numerous road closures of Folsom Dam Road. The final Supplemental Plan Formulation Report EIS/EIR was completed in February 2002 and included a temporary bridge as project mitigation. Although the U.S. Bureau of Reclamation (Reclamation) classed Folsom Dam Road for security and public safety in 2003, the final EIS (April 2005) for the road closure concluded that the dam road would be re-opened and managed by Reclamation in conjunction with the City of Folsom. Therefore, a bridge would still be needed for mitigation for road closure associated with flood control work at the dam. In September 2004, Congress authorized the Dam Raise Project, including a permanent bridge as mitigation. The draft SEIS/EIR evaluates five alternative plans, including no action. The main features of the alternatives include (from east to west) (1) reconfiguring the East Natoma Street-Folsom Dam Road intersection; (2) a four-lane roadway, two-lane roadway, or four-lane roadway transitioning to a two-lane roadway; (3) a four-lane bridge across the American River; (4) a four-lane roadway ro a two-lane roadway to Folsom-Auburn Road; (5) a new intersection at Folsom-Auburn Road; (6) new access road to Reclamation facilities; (7) Class I bike facilities on the bridge and Class II facilities on the roadway; and (8) relocation of American River Water Education Center, B. Parks Offices, and some Reclamation and SMUD facilities.
This project would mitigate for the Folsom Raise project and provide a complete transportation corridor across the American River.
