Do I need a USACE Permit? 

Visit the Regulatory Request System for more information on jurisdiction, types of permits, and the application process. 

Regulatory Request System (RRS) (Preferred Method) 

RRS is a modern, web-based platform launched nationally in January 2024 to simplify and expedite the permitting process. RRS offers a more transparent, consistent, efficient, and user-friendly experience for submitting permit requests and interacting with Regulatory offices. RRS provides general information on the Regulatory Program and allows the public to submit pre-application meeting requests and jurisdictional determination requests. On October 1, 2026, the Seattle Regulatory Division will fully transition to using the RRS as the primary method for receiving electronic applications. 

Mail Submittal (Hardcopy) 

The Corps will continue to accept paper copies of your requests if you are unable to submit them through RRS. Mail documents to: 

U.S. Army Corps of Engineers 
Regulatory Division 
4735 East Marginal Way South, Building 1202 
Seattle, Washington 98134-2329
