The U.S. Army Corps of Engineers permitting process is how 404 and Section 10 applications get decided. It is a completeness check, a public process on individual permits, and a written decision with conditions.
The usual steps
- Pre-application. Worth it when jurisdiction, alternatives, or mitigation are not obvious. Bring a delineation, not a concept napkin.
- Complete application. Drawings, purpose and need, alternatives, impact table, mitigation, and the other agency pieces (401, ESA, cultural) far enough along that the Corps can put the file on the clock.
- Public notice on individual permits. Comments are real. Ignoring them does not make them go away.
- Review. 404(b)(1) guidelines, public interest, district regional conditions, and any consultation.
- Decision. Permit, permit with conditions, or denial. Then you build the permitted plan — not the plan you wish you had submitted.
Districts we file in
Most of our waterfront and wetland files sit in Mobile, Vicksburg, or New Orleans District. Each has its own regional conditions and habits. A Mobile NWP PCN is not a New Orleans individual-permit package.
Cypress Environment & Infrastructure prepares the package and stays on the file. We do not promise timelines we do not control.
Questions about how this applies to a Gulf Coast site? Cypress Environment & Infrastructure works from Biloxi, Mobile, and Pensacola. Office hours are Monday–Friday, 9 a.m.–5 p.m.
