Assessment of stormwater best management practices

The University of Minnesota, through contract with the Minnesota Pollution Control Agency, has developed a Guidance Document that outlined and explained proper methodology for the assessment of stormwater best management practices (BMPs). The document promotes the "Four Levels of Assessment" which increase in difficulty and cost from 1 to 4:

  1. Visual Inspection
  2. Capacity Testing
  3. Synthetic Runoff testing
  4. Monitoring

The Guidance Document has organized existing stormwater BMPs into categories according to the process by which pollutants are removed from stormwater runoff:

  • Biologically Enhanced Practices
  • Filtration Practices
  • Infiltration Practices
  • Sedimentation Practices
  • Source Reduction
