Off the top of my head, I can think of 2 essential resources for getting started with your stormwater treatment design. First, check out the selection matrices provided at the Stormwater Manager’s Resource Center. Their selection guide focuses on 7 areas of concern:
- Land Use
- Physical Feasibility
- Climate/Regional Factors
- Watershed Factors
- Stormwater Management Capability
- Pollutant Removal
- Community and Environmental Factors
In addition to their selection matrices, there are plenty of valuable resources for getting started including construction specs for stormwater BMPs.
Second, check out the International Stormwater BMP Databsefor their valuable assessment of the efficacy of the most common stormwater BMPs (Detention Ponds, Wet Ponds, Wetland Basin, Biofilter, Media Filter, Hydrodynamic Devices, Porous Pavement).
