Carbon River Setback Levee Feasibility Study
Pierce County Planning and Public Works is conducting a feasibility study to increase flood protection and improve fish habitat conditions on the Carbon River near Bridge Street and Voights Creek. The project team is meeting with various stakeholders and the greater community. This study will evaluate four alternatives for setting back existing left-bank flood control levees on the Carbon River near Orting, Washington. A goal is to reach a common understanding of the perceived problems, values and opportunities of the community and area of the study. This information will guide the selection of a preferred alternative.
Throughout this study, Pierce County is committed to working with the community and nearby property owners. Community input on the four alternatives will help shape the future of the Carbon River Levee Setback Project.
- Improved flood protection
- Reduced levee damages and repair costs
- Reduced flooding impacts
- Improved fish habitat and water quality
- City of Orting stormwater pond
- Stormwater drainage
- Existing levee
- Residential development
- Foothills Trail
- Agriculture property
The project is located between Carbon River Mile (RM) 3.0 to 4.4 (blue shaded region) in an area used by several fish species listed as threatened in the state of Washington. The yellow shaded region represents future potential study area.
Pierce County is funding this study through a grant obtained from the Salmon Recovery Funding Board (SRFB), Project No. 16-1545P.
Funding and schedule for project permitting, design and construction have not yet been identified.
Community input on the four alternatives is vital to help shape the future of the Carbon River Levee Setback Project planning efforts. A series of open houses, mail notices, surveys and interviews were held and made available to the community, stakeholders and to those directly impacted by this project. This allowed for the community to review, comment, and give input on the alternatives. Comments and input that were received are provided and summarized in the feasibility report document.
Update October 1, 2021: The final report that addresses information and results of the feasibility study are now available for you to view.
The feasibility study develops and evaluates four conceptual alternatives for setting back the existing left bank levee facility on the Carbon River. It also identifies and recommends a preferred alternative. The preferred alternative will be further considered during potential future project phases that include continued land owner and community outreach and coordination. Depending on results from further land owner and community outreach comments and coordination, the project may enter future phases that addresses, preliminary design, permitting and construction issues. Funding and schedule for potential future phases have not been identified.
