Stormwater Master Plan Update

Project Background

The City of Wilsonville is finalizing its project to update the Stormwater Master Plan. The City's Stormwater Master Plan is a comprehensive planning document that guides how the community will address and manage urban storm runoff in the future. Managing the City's stormwater helps protect the environment, property, and supports healthy watersheds for fish, wildlife, and recreation. This video from the Environmental Protection Agency provides a more in-depth explanation of the benefits.

The Draft plan is scheduled for review at public hearings before the Planning Commission (March 13) and the City Council (April 1) prior to adoption. Adoption of the Stormwater Master Plan is anticipated in April 2024.

In 2021, in conjunction with the initiation of the Stormwater Master Plan, a public survey was developed to inform and guide the master planning process. As the Stormwater Master Planning process concludes, we’d like to hear your current thoughts about Wilsonville’s stormwater services and any stormwater-related topics you’d like to learn more about.
