The USGS, in cooperation with Federal, State, and municipal agencies, have recently incorporated watershed-scale stormwater infrastructure data into the publicly accessible StreamStats web application for Washington, D.C. and the Mystic and Neponset watersheds in Massachusetts. Using high-resolution lidar-derived elevation data and municipal stormwater infrastructure datasets, StreamStats can compute a connected network of surface and piped flow that more accurately represents urban topography and stormflow. The updated StreamStats functionality supports stakeholder efforts to address stormwater challenges in urbanized areas by allowing users to view the network of stormwater pipes and inlets, delineate drainage areas, and compute available basin characteristics. This presentation will describe the data, methods, challenges, and advantages to developing this urban stormwater functionality in StreamStats.
