Built by licensed Professional Engineers who have spent their careers navigating Florida's ERP permitting process, not software developers guessing at regulatory requirements. Every feature in SWMLabs reflects methodology that has been tested against real projects and real submittals.

What engineers are saying

I love the BMP routing diagram! I typically make a BMP map for my submittals and this would eliminate that need. I also appreciate the explanations of the methodology at each calculation step - it's almost as if you are walking through it with a reviewer.

In my experience, SWMLabs is an intuitive application that knocks hours off of BMP development. Geolocated HUC12, soils, and land use information makes project setup quick and easy. The interface for setting up BMPs is strait forward and easy to adjust. Finally, the reporting is thorough and makes a great addition to the drainage narrative.
