Salmon Habitat Enhancement at Muir Woods, Ph 2

 
 

This project is to conduct salmon habitat restoration actions in Redwood Creek at Muir Woods National Monument. The work requires use of heavy equipment within the channel, per drawings, to remove rock slope protection (RSP) from banks, grade some banks, install rock in tie-backs, install Large Woody Debris structures, and remove an asphalt trail. The work requires setting up three water diversion systems while meeting downstream flow and water quality requirements. The work entails slow and restricted access and many environmental protections for highly sensitive resources such as endangered salmon, understory vegetation, and redwood trees. The work occurs in three segments of the creek (Areas 5, 6 and 7). Two work areas (5 and 6) will not be accessible to equipment until Area 7 is fully dewatered.
