Belmondo Levee 2020 Repair

Learn about planned repairs to the Belmondo Levee near the Cedar River Trail. The project will reduce flood risks to the trail, State Route 169 (Maple Valley Highway), and a buried regional fiber optic line.
Project overview

The Belmondo Levee on the Cedar River reduces the risk of flood damage to the Cedar River Trail, a regional fiber optic line, and State Route 169. A significant flood in February 2020 damaged the Belmondo Levee creating a flood and safety risk.

The King County Flood Control District (District) and King County, as service provider, plan to repair the damaged levee and make habitat improvements at the site in the summer of 2025.

What is a levee?

A levee is a raised structure built along a riverbank to contain, control, or divert the flow of water and protect the land along the river from temporary flooding. A levee is usually made of earth and runs parallel to the course of a river.

Project goals

  • Reduce flood and erosion risks to SR 169, Cedar River Trail, and public utilities.
  • Enhance habitat for salmon and other fish and wildlife.

Construction impacts

Plants along the riverbank of the Belmondo Levee as a car drives by on the leftThe District and King County are working to limit the impacts of construction. Construction will require short-term closures to the Cedar River Trail for safety. At other times, we will provide a temporary bypass for trail users. Trail users can expect intermittent delays up to 15 minutes during construction. Sign up for the King County Parks Newsletter to receive updates about the trail so you can plan ahead.

If necessary, there may be traffic control for trucks and equipment accessing State Route 169. We will post signs near the project site and notify nearby businesses and residents before construction begins. Check this webpage for more details on trail and road impacts closer to construction.
