LA did a similar project and there's a pretty thorough user guide online at
http://www.labmpmethod.org/. I think it will be very useful as we develop something like this ourselves. Their approach was:
- Prioritize catchments based on need (i.e., pollutant-loading, receiving water issues, etc.);
- Identify potential BMPs opportunities within high priority catchments (based on factors such as land ownership, etc.);
- Identify appropriate BMPs (based on factors such as cost, maintenance, effectiveness, etc.); and
- Develop site-specific implementation strategies (based on site-specific evaluations).
Some questions I have:
- are we focusing on wet weather only or including dry weather?
- what pollutants? bateria? metals? trash?
- what pollution data can we get?
