Willamette River Stormwater Improvement Project

Welcome to our online open house, thank you for joining!


We are building stormwater treatment facilities to clean stormwater runoff from the Fremont Bridge (I-405), the St Johns Bridge (U.S. 30 Bypass) and U.S. 30 in NW Portland. The project has approximately $12 million from state and federal resources to complete preliminary design and acquire right-of-way from 2022-2024. Construction funding is being requested but this additional funding has not yet been awarded. This online open house provides a summary of the stormwater improvements and an opportunity to sign up for updates about the project. In this open house, you can learn about:

  • The stormwater improvements at the Fremont Bridge, St Johns bridge, and U.S. 30;
  • Their environmental and community benefits;
  • Anticipated traffic impacts;
  • Details about the project schedule; and
  • How you can stay connected.
