Best Management Practices
City of Bothell has adopted the BMP requirements found in King County’s Stormwater Pollution Prevention Manual. As King County periodically updates the manual, always check the King County website for the most up-to-date BMPs.
What are best management practices?
Best management practices (BMPs) describe ways to manage your land and activities to mitigate pollution of surface and groundwater near you.
