Best Management Practices (BMPs) for Storm and Surface Water Management
About Best Management Practices
Best Management Practices (BMPs) are a method by which the adverse impacts of development and redevelopment are controlled through their application. BMPs are defined in the state's storm water Manual as "schedules of activities, prohibitions of practices, maintenance procedures, and structural and/or managerial practices, that when used singly or in combination, prevent or reduce the release of pollutants to waters of Washington State." The types of BMPs identified by the state are source control, runoff treatment, and flow control.
The primary purpose of using BMPs is to protect beneficial uses of water resources through the reduction of pollutant loads and concentrations, and through reduction of discharges (volumetric flow rates) causing stream channel erosion.
This page highlights a few best management practices for storm and surface water management. Additional resources include the Association of Washington Cities Stormwater Program: Best Practices for Effectiveness and the Department of Ecology's Puget Sound Ecosystem Monitoring Program Stormwater Work Group page.
