Floodplains by Design grant program

Floodplains by Design (FbD) is our primary grant program for projects that help communities live better in their floodplain. This competitive grant program is a component of a public-private partnership led by Ecology, The Nature Conservancy, Bonneville Environmental Foundation, and the Puget Sound Partnership. It is focused on re-establishing floodplain functions in Washington’s major river corridors as well as reducing flood risk.

Floodplains provide important habitat for salmon, rich soil for farms, and beautiful backdrops for residents and visitors to Washington. In the past, attempts were made to control rivers, thinking flooding could be stopped by walling off rivers with levees, straightening them, and laying a grid of commercial and residential development across them. Now, salmon runs are disappearing, and more people live in the path of dangerous floodwaters.

Local and Tribal governments, along with nonprofit organizations, are using FbD grants across Washington to complete multi-benefit projects that reduce flood hazards to communities while restoring the natural functions of rivers and their floodplains. These FbD projects bring together many different stakeholders in the floodplain to:

  • Improve flood protection for communities that live and work in floodplains
  • Conserve and restore habitat for salmon and other important aquatic species
  • Preserve farmland to keep agriculture viable for future generations
  • Improve water quality
  • Enhance outdoor recreation
