Abstract: 

The Chicago-based Center for Neighborhood Technology has created a simple web-based tool that quantifies the reduced runoff and cost of using alternatives to curbing and piping stormwater offsite. While larger cities have engineering staff who use more sophisticated tools, this one is useful for towns, homeowners and citizen volunteers on municipal committees.

First choose from six "green interventions" such as using porous pavement on driveways and sidewalks. Then choose a development scenario such as suburban new development. Finally fill in 12 factors such as size and slopes. The calculator then produces extensive financial and hydrologic details such as:

  • Total peak discharge reduction
  • First year and 100 year comparative costs and benefits
  • Present value and per-lot financial detail
  • Maintenance detail
  • C02, air pollution and groundwater benefits
