Jessica Gould and Mary Ellen McCarty from the Philadelphia Water Department will discuss GIS for Green Stormwater Infrastructure Implementation in Philadelphia. Green Stormwater Infrastructure (GSI) is  an emerging stormwater management method adopted by PWD in 2009. This program uses vegetation, soils, and other elements to reduce stormwater runoff. GIS is used to supplement GSI in all project phases, from site selection and design to data cataloging in enterprise geodatabases. During the session, presenters will describe their new GIS data model developed to house GSI asset geometries and how it connects to existing work order management systems to enable maintenance, monitor, and easy reporting.
