Regulatory Public Notices

The U.S. Army Corps of Engineers regulates activities affecting wetlands and other waters of the United States under Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act. Public involvement is central to this process, with input from agencies, tribes, organizations, and citizens helping ensure balanced, informed permit decisions that support development while protecting aquatic resources.
