Document Description
Project implementation would involve removing the 60-foot-long, 15-foot-diameter circular corrugated steel culvert and replacing it with a 70-foot-long, 22-foot-wide bridge. The project would involve working in a 300-foot reach of the channel bed that is approximately 30 to 50 feet wide. The project footprint would be approximately 21,100 sf or .48 acres and including the temporary access road, the site impact total is .79 acres, 34,400 sf. In addition to the removal and replacement of the culvert, the design includes the construction of a natural channel stabilized with native vegetation, boulders, and log structures. These features are designed to provide endangered species habitat as well fish passage for the project. The project would include construction of a temporary road that would provide access to the site and the immediate surroundings.
