    Project Alteration Reviews: Section 408

    Section 14 of the Rivers and Harbors Act of 1899 authorizes the Secretary of the Army to grant permission for alterations to existing U.S. Army Corps of Engineers projects under certain circumstances. Authority to approve alterations has been delegated to the District Commander in most cases, although certain alterations require approval from the Director of Civil Works at the Corps’ headquarters. Section 408 provisions apply to works that were built by the Corps and are locally maintained, such as local flood control projects. They also apply to works that are operated and maintained by the Corps, such as locks and dams. Proposals submitted for Section 408 review and approval undergo a rigorous engineering, policy and environmental review by the Corps and, if required, independent external peer review.
