Description: This dataset was developed to facilitate stormwater pollution control and tracking by mapping Hydrologic Response Units (HRUs) at a regional-scale for the SNEP region, which covers the watersheds of Narragansett Bay, Buzzards Bay, Nantucket Sound (including Martha’s Vineyard, Nantucket, and the south-draining portions of Cape Cod. Readily available GIS datasets sourced from MassGIS, RIGIS, NOAA, and USGS were integrated to identify HRU features by land use, impervious cover, hydrologic soil groups, and percent slope of terrain. Each HRU's stormwater pollutant loading was estimated by using EPA's Opti-Tool and historical weather data from the region.
