Stormwater Action Monitoring - Effectiveness studies

SAM's effectiveness studies measure the stormwater management actions in Western Washington and communicate useful findings on what works and what doesn't work. The Stormwater Work Group (SWG) organizes permittees and stakeholders to select the SAM study topics.


What are we learning?

SAM effectiveness projects can occur at site or regional scales and the results can be used across jurisdictions.
