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. |
