Stormwater Utility Analysis & Wastewater Master Plan

Did you know that the community’s stormwater system serves a watershed area of approximately 10,700 acres through an integrated system of catch basins, detention basins, open channels (drainageways, creeks) and storm sewers? The service area within the Urban Growth Boundary encompasses roughly 8,400 acres of the watershed. In fact, our earliest records for the system date back to facilities constructed in 1911 that have continued in service for more than 100 years.

McMinnville's Stormwater facilities include:

• 3665 Catch Basins
• 17 Detention Basins
• 45 Miles of open channel drainageways
• 114 miles of storm sewers

These facilities are significant, sustained investments in the stormwater system. Their presence minimizes health and safety risks during flooding, protects properties from damage due to localized flooding, protects our water quality by capturing sediments, heavy metals and nutrients bound to these solids, and reduces oil and grease from entering our waterways.

This is why we have initiated a Stormwater Utility Analysis. This analysis will help us explore more equitable and sustainable ways to fund the operation of the stormwater system.
