Stormwater Planner

Drop a point anywhere in the United States to preview which jurisdiction governs stormwater construction requirements. We are building deeper permit schedules, contacts, and rainfall thresholds so you can plan jobs faster.

Stormwater Planner is in beta and currently under development. Expect rapid improvements and occasional changes.

Click anywhere on the map to drop a marker, then use the button below to generate a jurisdiction and watershed report. You can drag the marker to refine your location before requesting a new report.
