Impervious Area Mapping as an Accurate Stormwater Runoff Indicator
Track: Water, Wastewater, and Stormwater
Authors: Daniel Ngoroi, Rose Haverkos
Imperviousness is a known contributor of urban runoff. Local government jurisdictions around the country use this measure to ensure that users of stormwater systems pay their fair share for the maintenance of these systems. This presentation highlights the use of GIS analysis to gauge whether impervious surfaces mapping provides a fair, equitable and accurate measure of anthropogenic runoff and whether this method is a sustainable way to support maintenance of these stormwater systems.
