ArcGIS Pro Tips: Delineating MS4 Drainage Catchments

Drainage catchments are a vital GIS layer for cities and counties to mitigate the impacts of flooding, accurately predict pollutant loading, and optimize stormwater asset management activities. In this webinar, Josh and Michelle share their favorite best practices for GIS stormwater mapping and using Esri’s ArcGIS Pro to delineate urban catchments. They also show examples of how our 2NFORM platform leverages that data for MS4 compliance reporting, assessing the consequence of failure for BMPs, and tracking TMDLs.
