As of March 2018
Phase: Draft Study in development

We have started a study to decide if the City should build a new regional stormwater facility (RSF).  RSFs have been built successfully by nearby cities. This approach allows lower costs and improved efficiency through larger scale. Benefits extend to the environment, the City, and developers.  The RSF being studied could help achieve the goals of the Aurora Square Community Renewal Area (CRA). Funding from developers is a primary objective for a possible City RSF.

Three candidate sites are considered for a possible future facility:

  • Shoreline Community College Greenwood Parking Lot – Infiltration Pond (Alternative 1)
  • Westminster Way north of N 155th Street – Infiltration Vault (Alternative 2)
  • Fremont Place N south of N 163rd Street (Gloria’s Path Park) – Bioretention (Alternative 3) or Infiltration Vault (Alternative 3B).

Detailed analysis including comparison of alternatives, estimated costs, and potential funding mechanisms can be found in the Draft Boeing Creek Regional Stormwater Facility Feasibility Study. This draft study will be completed soon and will be available to the public on this website upon completion.


  • Draft study available: ~ March 2018
  • City Council meeting to discuss staff recommendation: ~ April 2018 (exact date to be determined)
  • Final Study: Spring 2018

Project History

The idea for a City RSF for Aurora Square first appeared in the December 2014 Aurora Square Planned Action Draft Environmental Impact Statement (Appendix C). The current study began in March 2017.
