How does PERMT work?
  • You are required to obtain federal, state, and local permits before doing any construction in the flood plain or near a river or stream. There are exceptions for certain projects on very small streams. When you begin the Joint Application Process, the system will walk you through steps to determine if a joint application is required for your project.

  • By using PERMT and following the prompts, your Joint Application will be submitted to Iowa DNR Flood Plain, Iowa DNR Sovereign Lands and the US Army Corps of Engineers, Rock Island District for review.

  • This electronic application program does not submit your Joint Application to county or city officials for local permitting. You are responsible for contacting local permitting officials and obtaining local permits prior to construction.

  • PERMT also allows you to electronically request Base Flood Elevations, Environmental Reviews, and Flood Plain/Declaratory Order for your Animal Feeding Operation and check on the status of your applications.

How will I know if my project has been properly submitted and reviewed?

By following the step by step processes you will eventually “Submit” your application. An email will be sent to you confirming receipt of the application. This email is not an approval of your project.

Iowa DNR will send out one final response for both the Iowa DNR Flood Plain and Sovereign Lands programs. The US Army Corps of Engineers, Rock Island District will communicate with you separately and directly regarding the status and final response to your Joint Application.
