Project Status

The project is under construction.  Two construction seasons (2016 and 2017) are needed to complete the project.  Construction during the summer of 2016 included clearing portions of the project area, grading the site and installing engineered log structures.  Time-lapse and flyover videos (YouTube) of the project site illustrate elements of the 2016 construction process.

Project area

The Countyline reach of the Lower White River is bounded by the A Street and Burlington Northern-Santa Fe (BNSF) Railway bridges at the upstream end (River Mile 6.33 ) and the 8th Street Bridge at the downstream end (RM 5.00). The Countyline reach spans the King-Pierce County boundary.

Project elements

  • Acquire all at-risk and necessary properties required to construct the project.
  • Construct 6,000 lineal feet of new setback levee along the landward edge of a forested buffer to protect existing properties and structures.
  • Construct 5,780 lineal feet of bio-engineered bank revetment along the existing wetland edge to protect existing properties and structures.
  • Install engineered log structures in the existing wetland complex.
  • Remove approximately 4,500 lineal feet of levee and bank armoring.
  • Restore a forested riparian buffer (approximately 18 acres) adjacent to the wetland.

Overview

Significant flooding in January 2009 impacted more than 100 residences and numerous businesses in the City of Pacific and temporarily closed Stewart Road E due to overtopping by floodwaters east of the 8th Street Bridge. The goal of the Countyline Levee Setback project is to reduce flood elevations in the City of Pacific by removing the existing levee and reconnecting the river with 121 acres of off-channel aquatic habitat that has been isolated from the river for nearly a century. The Countyline Levee Setback project will provide significant flood risk reduction benefits for more than 200 residential properties. The proposed project is a combination of property acquisition, levee removal, setback levee construction, and floodplain restoration within the Countyline reach of the Lower White River in the cities of Pacific and Sumner.
