Mitigation
Mitigating the environmental impacts of unavoidable development actions in the nation's wetlands and other aquatic resources is a central premise of Federal wetlands programs. The Clean Water Act Section 404 permit program relies on the use of compensatory mitigation to offset unavoidable damage to wetlands and other aquatic resources through, for example, the restoration or creation of wetlands.

Regulatory

The mission of the U.S. Army Corps of Engineers Regulatory Program is to protect the Nation's aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions.

Welcome to the Baltimore District's Regulatory homepage. The U.S. Army Corps of Engineers has been regulating activities in the nation's waters since 1890. At first, this program was meant to prevent obstructions to navigation, although an early 20th century law gave us regulatory authority over the dumping of trash and sewage. Passage of the Clean Water Act in 1972 greatly broadened this role by giving the Corps authority over dredging and filling in the "waters of the United States," including many wetlands.
