The new bridge and roadway will feature improved storm water collection, conveyance and treatment. Preventing direct runoff of polluted storm water into the creek will improve water quality.
This project will directly affect Salmon Creek, which supports salmon, steelhead and trout populations along with other plant and animal species. Salmon and steelhead that use the creek are listed as “threatened” by the federal Endangered Species Act. Environmental permits will define how construction can proceed while minimizing impacts to aquatic life. The proposed streambed restoration will remove a partial fish barrier and enhance aquatic habitat.
Improvements in this reach of Salmon Creek have been identified by the Lower Columbia Fish Recovery Board as a critical area for restoring historic habitat throughout the Salmon Creek sub-basin. The in-channel improvements will also help prevent future stream erosion and protect the bridge.
