Stormwater Infrastructure and other features - Area Features

Metadata Updated: August 4, 2018

This data was collected and compiled for various towns in watersheds (currently including the Missisquoi Basin, Winooski Basin, Connecticut River Basin, Lamoille River Basin, and the Otter Creek Basin) around Vermont and shows as accurately as possible the stormwater infrastructure within these municipalities. Polygon data was collected and compiled through field observations of area or treatment features, digitizing of georeferenced town plans and record drawings, the digitizing of state stormwater permit plans, and the knowledge of members of the municipality. The points, lines, and polygons, show the locations and connections of various features of the stormwater infrastructure, as well as some points included for additional information. Drainage systems were mapped using ArcMap 9, 9.3.1 and 10 to establish the connectivity of the stormwater features, and to show where runoff from impervious surfaces in various subwatersheds within an urbanized area eventually enters the receiving water. Subwatershed boundaries were drawn using field data, topographic maps, and a Digital Elevation Models (DEM). Using an impervious surface layer, which was created in different ways for different urbanized areas, the subwatersheds were then prioritized by the percentage of impervious within each subwatershed as well as how directly connected that impervious surface was to the outfall. Retrofit stormwater treatment best management practices and locations were suggested for the highest priority subwatersheds, where feasible, in order to treat the runoff before it enters the receiving water.
