Project Overview

Sign up for announcements

King County, as the primary service provider to the King County Flood Control District (District), is planning to repair the Fort Dent Levee. This levee is located in the City of Tukwila on the right bank of the Green River and reduces erosion and flood risks to the Green River Trail, Fort Dent Park, and Starfire Sports.

The Fort Dent Levee is a King County flood protection facility and was damaged by flooding in 2019 and 2020. King County is planning to repair and stabilize the levee in 2024. Construction will include planting native plants to provide shade and improve fish habitat, and to help reduce long-term maintenance needs and costs.

King County expects to complete this project by 2025. Repairing this levee reduces flood risks to people and property. Timely action may also minimize damage to fish habitat and prevent the need for costly emergency repairs.

Project Goals

  • Perform levee repairs to minimize future maintenance costs and reduce flood risks to people, community resources, and infrastructure.
  • Maintain or improve habitat for salmon and other aquatic life.
  • Limit disruptions to use of the Green River Trail, Fort Dent Park, and Starfire Sports.

King County will post clear signage to inform individuals of construction impacts, as shown in a 2020 project above.

King County is working to limit the impacts of construction. As the project is designed and permitted, we will update this page with impacts to roads, sidewalks, trails, or parks in the area. We will also post signs and flyers near the project site and notify local businesses and residents with updates as construction is planned and completed. If you are interested in receiving updates, please sign up for the project email list.
