An online stormwater calculator offers another tool to help protect waterways from runoff. The U.S. Environmental Protection Agency (EPA) released its National Stormwater Calculator to help property owners, developers, landscapers, and urban planners make informed land-use decisions to help prevent stormwater runoff, according to an EPA news release.
The calculator is a desktop application that estimates the annual amount of stormwater runoff from a specific site based on soil conditions, slope, land cover, and historical rainfall records, the news release says. Users can download the application, enter any U.S. location, and select different scenarios to learn how green infrastructure changes can mitigate runoff. The tool was designed to help determine the cost-effectiveness of different green infrastructure solutions.
