MS4 compliance reporting

2NFORM streamlines your MS4 annual report compilation efforts. 2NFORM tracks and analyzes all of your program activities throughout the year and summarizes them into the corresponding section of your MS4 permit. Automated short narratives, populated with your program details, concisely summarize your program progress over the year, including quantitative values calculated from your records within 2NFORM.


The embedded 2NDNATURE science provides you with quantified stormwater pollution reduction accounting to track and report the clean water impact of your program efforts.

Better together


As an Esri partner, we’ve taken great care to ensure you can leverage your stormwater data using the breadth of tools and functionality of ArcGIS. 2NFORM brings stormwater best practices and science to ArcGIS.
  • Inventory and inspect stormwater assets using ArcGIS Field Maps and 2NFORM mobile forms.
  • Inform and collaborate with stakeholders and the community using ArcGIS Hub or Hub Premium. 2NFORM makes it possible to incorporate data from your stormwater program into dynamic maps and dashboards. Our experienced team is happy to assist you in configuring your public education & outreach website with ArcGIS Hub.
  • Share stormwater data with your department and organization. 2NFORM comes with our enhanced stormwater foundation template for your ArcGIS system. Developed by a team of stormwater practitioners and scientists, it helps you organize your programs’ geospatial data.
When paired together, 2NFORM and ArcGIS help accelerate your journey toward less polluted waterways, less flooding, and more resilient stormwater management practices.
