The National Green Values™ Calculator (GVC) is a tool for quickly comparing the performance, costs, and benefits of Green Infrastructure, or Low Impact Development (LID), to conventional stormwater practices. The GVC is designed to take managers step-by-step through a process of determining the average precipitation at a site, choosing a stormwater runoff volume reduction goal, defining the impervious areas of the site under a conventional development scheme, and then choosing from a range of Green Infrastructure Best Management Practices (BMPs) to find the combination that meets the necessary runoff volume reduction goal in a cost-effective way. The GVC is designed for site specific analyses only and should not be applied to entire cities, counties, or neighborhoods.
