Description    


Initial Alternatives included: a single span bridge with full channel cacity, a single span with moderate flood capity. The selected alternatives involved the replacement of the existing crossing with a single span bridge, which varied in structure type and flood capacity. A 90-foot span truss style bridge was selected as the preferred approach and 65% designs were developed.

Project Benefit    


Future replacement of the Arizona crossing will allow access to more habitat for spawning and cover.

          Description and scope of the plan implemented
          The primary objective of the Project is to determine an appropriate Arizona crossing replacement/adjustment on Sisar Creek that will restore steelhead passage/migration from the Pacific Ocean to vital rearing and spawning habitat. This Project is particularly crucial under the current drought conditions as these upstream habitats display increased canopy cover and/or are spring fed with cooler water, which keep instream temperatures lower/suitable for steelhead survival which are issues stated in the Recovery Plan.
