This $3 million project corrected chronic bank erosion threatening US 12 and aquatic habitat in the Naches River, north of Yakima near the 16th Avenue interchange. WSDOT and the contractor moved the Naches River channel away from US 12 and constructed rock and log structures adjacent to the highway to protect the roadway from future flooding.
This project is a result of an effective partnership between the City of Yakima, Yakima County, and WSDOT. The partnership’s long-term goal is to improve the functionality and stability of public infrastructure investments in the Lower Naches River floodplain, while reducing costly emergency repairs and improving aquatic habitat.
New embankment protection along US 12 will limit future erosion problems caused by the Naches river. Restoration of the existing Naches riverbank will protect the roadway and enhance the environment.
| Protects Environment
This project will improve pool habitat for fish species and restore vegetation along the riverbank.
| Economic Incentive
This project provides a permanent solution to chronic erosion problems, reducing public costs and on-going maintenance work for temporary repairs.
Partnerships & Cooperation
The lower Naches River floodplain is a common geographic area shared by irrigators, federal and state resource agencies, fishermen, and the public. WSDOT, Yakima County, and the City of Yakima formed the Lower Naches River Partnership Group (NRPG) to seek mutually beneficial solutions. Through a coordinated partnership effort, the NRPG hopes to make decisions collectively, share and accumulate data and information, and help protect the existing environment for all to use and enjoy.
This project was funded through the following sources*:
- 2005 Transportation Partnership Package - $2.4 million
- Existing Funds - $0.6 million
- Total Funding Available from all sources - $3.0 million
*As approved in the 2008 Supplemental Transportation Budget.
