The Green Values: Stormwater Toolbox was originally developed primarily for use by planners, engineers and other municipal staff. This tool is utilized by entering information specific to the particular lot or land locations, size, coverage type, conventional development and then determining a runoff reduction goal. This toolbox is accompanied by a list of state, local and national standards relative to runoff and stormwater management. Once information is entered into the National Stormwater Calculators, green improvement options and advanced options allow the users to fine tune their goals as well as estimate benefits and costs for those green infrastructure improvements.
