Pringle Creek Stream Restoration
Otak carried forward a project at the 60% design phase at the site of the old Boise Cascade Mill on Pringle Creek in Salem, Oregon. The project included demolition of an overhead slab and supporting columns as well as a holding tank at ground level and a concrete fish ladder. Pringle Creek was historically confined by these structures; Otak designed a new stream channel through this urban reach to restore a more natural stream condition and improve fish passage. We also provided large wood structures for habitat, performed restoration design calculations for bed gradation and channel geometry, and developed construction plans for the site. Construction was completed the summer of 2019.
Resolving Issues and Constraints
The project was punctuated by a restricted design schedule. Otak moved quickly and used available data to begin design while additional field data was being collected. Through frequent communication with the City of Salem, Otak was able to efficiently deliver a design that met the City’s needs and within the restricted design time frame.
