The key component of stormwater management is to obtain a good understanding of the data describing the system so that regulatory, maintenance, and capital decisions concerning the system can be made. It is important to be able to both accurately characterize a City's storm drain system as well as identify activities within watersheds which impact it. The City of Norfolk recently completed a review of its storm system inventory database to define its long term information needs, and to develop an implementation plan that, over time, will allow it to extract system information in a timely and cost effective manner. This paper describes a plan recommended for Norfolk and presents the data structure of a geographic information system (GIS) capable of meeting a variety of stormwater information needs.
