1. Identify stormwater footprint
2. Quantify existing stormwater loads
3. Set goals
4. Quantify existing stormwater controls
5. Assess current status
6. Prioritize (cost-effectiveness/env. metrics)
7. Implement (capital improvements/grants)
8. Track progress!
Current permit requirements for TMDLs…
Eliminate any future sampling requirements
Eliminate any future TMDL/retrofit requirements
Potential MS4 Permit exemption?
To be determined…
