Stormwater Documents
The City of Spokane adopted a Stormwater Management Plan (SMP) in 2004 that addresses stormwater quality
and quantity issues. The planning team reviewed stormwater quality controls, drainage complaints and flood control.
The planning process identified problem areas, characterized stormwater quality and quantity in Spokane, evaluated
City Stormwater Management Programs, and is developing compliance with the
Eastern Washington Phase
II Municipal Stormwater Permit . With the permit set in place, the city must implement our SMP to accommodate the permit requirements.
The current SMP is posted below, as are previous Plans, annual reports, the Spokane Regional Stormwater Manual and some educational materials.
Annual Reports
The Phase II permit mandates the City to submit an annual report to the Department of Ecology. To view, please click on the desired report.
