About Section 408

Section 408 is the process that allows alteration to a federally authorized project. The proposed project cannot pose a risk to the public interest and will not impair the usefulness of the federally authorized project. Examples of federally authorized projects include, but are not limited to levees, dams and the federal navigation channel.

This requirement was established in Section 14 of the Rivers and Harbors Act of 1899, codified at 33 United States Code (USC) 408 (Section 408).

15-Day Notice

This Public Notice announces the Section 408 review of the Exit 21 Interchange. 

Portland District is reviewing the City of Woodland’s proposal to conduct geotechnical investigations in support of the I-5 Exit 21 Interchange Project in Woodland, Washington. 

Alteration of a federally authorized project: This project proposes to conduct several borings in support of the Exit 21 interchange design. Up to four six-inch hollow stem auger borings and two 3.5-inch push probe environmental borings are proposed within Cowlitz Diking Improvement District No. 2 (Woodland) Lewis River Levee. The proposed project may alter the Lewis River Levee and therefore require authorization from the Corps, pursuant to 33 USC 408 (Section 408). Section 408 provides authority to the Secretary of the Army to grant permission for the alteration or modification of Corps federal civil works projects when, in the judgment of the Secretary, such alteration or modification will not be injurious to the public interest and will not impair the usefulness of the project.

Consideration of Comments: USACE is soliciting comments specific to this project from the public, federal, state, and local agencies and officials, and other interested parties. Comments will be considered in determining whether it would be in the public interest to proceed with this action.
