Cooperative GIS Mapping for Massachusetts Communities and the MassDOT

The 2016 Massachusetts Small MS4 General Permit requires that Municipal Separate Storm Sewer Systems (MS4s) be mapped. With MS4s interconnected across properties, maps are developed by different organizations which makes it difficult to determine where stormwater runoff is collecting and how stormwater infrastructure is managed. Through interviews and geospatial data analysis, we developed recommendations for facilitating the collaboration and integration of geospatial data between Central Massachusetts Regional Stormwater Coalition communities and the Massachusetts Department of Transportation.
