The purpose of a Section 408 review is to ensure that the Congressionally-authorized benefits of a USACE project are not undermined by an alteration made by others, and to ensure the alteration is not injurious to the public interest (e.g., flood risk management, coastal storm damage reduction, navigation).
The U.S. Army Corps of Engineers (USACE), Norfolk District is required to review requests initiated by private, public, tribal, or other federal entities that propose to make alterations to, or temporarily or permanently occupy or use, any USACE federally authorized civil works project pursuant to 33 USC 408 (Section 408) and in accordance with Engineering Circular 1165-2-220.
The USACE will then make a determination as to whether the proposed action is injurious to the public interest or affects the ability of the project to meet its authorized purpose. Following the review, the USACE will make a 408 Determination as to whether the proposed alteration, occupation, or use of the federal project is approved or denied.
