Innovative Technologies for Storm-Water Management Programs in Small Urbanized Areas

Abstract

Small urbanized areas (UAs) as defined by the U.S. Census and the Environmental Protection Agency (EPA) have a population between 50,000 and 100,000, and a population density of at least 1,000 people per square mile. Under Phase II of the National Pollutant Discharge Elimination System, storm-water managers in these UAs must preserve predevelopment hydrology through compliance with qualitative regulations—an often impracticable task given the limited resources of these municipal authorities and the diffuse hydrologic impacts of urbanization. The objective of this paper is to assist storm-water managers by providing a geographic information system (GIS) workflow supported by
