Additional Resources

U.S. EPA National Stormwater Calculator (2013)National Stormwater Calculator

This is “a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States . . . Estimates are based on local soil conditions, pharm land cover, and historic rainfall records.” Much of this data (e.g., soil type, soil drainage, topography, annual rainfall, etc.) is available in layers within the tool itself.

Low Impact Development controls, such as pervious pavement, disconnects, or rain gardens, can then be added in to calculate the annual runoff.

Extensive information is available to assist users, such as site developers, landscape architects, urban planners, and homeowners.

Available for download here (the program takes less than one minute to install).
