Stormwater Infrastructure
This data was collected and compiled for various towns in Vermont and shows as accurately as possible the stormwater infrastructure within these municipalities. Line data was collected and compiled through field observations determining pipe locations and directions on ortho-photos, 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 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). 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.
