Expiration date: 11/15/2023

Interested parties are hereby notified that a request for permission to alter a U.S. Army Corps of Engineers (USACE) project pursuant to Section 14 of the Rivers and Harbors Act of 1899 (33U.S.C. Section 408) has been received and will be evaluated by the Norfolk District. Written comments, including any objections to the proposed alteration, stating reasons therefore, are being solicited from anyone having an interest in the requested alteration. The authority to grant permission for temporary or permanent use, occupation or alteration of any USACE Civil Works project is contained in Section 14 of the Rivers and Harbors Act of 1899, as amended, codified at 33 USC 408 (“Section 408”). Section 408 authorizes the Secretary of the Army to grant permission for the alteration or occupation or use of a USACE project if the Secretary determines that the activity will not be injurious to the public interest and will not impair the usefulness of the project. The proposed action is also subject to the requirements and objectives of Executive Order (EO)11988, Floodplain Management and has the potential to impact floodplains. This notice complies with Section 2(a)(4) of EO 11988 and requests advance public comment to determine if there are any public concerns regarding potential impacts on floodplains.

Actions that encroach upon a USACE federal project require a Section 408 review to determine no negative impacts will occur as a result of project implementation. The City of Norfolk’s Office of Resilience is requesting Section 408 permission to relocate and replace an existing water main and install a new 24-inch inner diameter/30-inch outer diameter water main to maintain water service for thousands of residents in Norfolk and Chesapeake, Virginia. The new water main will be installed via horizontal directional drill (HDD) with the top of pipe at mid-channel approximately 66 feet below the channel bottom or an elevation of -100 feet mean lower low water (MLLW). The existing water main will be abandoned in place. Eastern Branch of the Elizabeth River (EBER) portion of the Norfolk Harbor and Channels Federal Navigation Project (federal project), which is operated and maintained by the U.S. Army Corps of Engineers, Norfolk District (USACE/Corps), will be altered by the proposed activity/activities via the HDD of the waterline underneath the channel. The project is also being conducted in support of the Norfolk District’s Norfolk Coastal Storm Risk Management (NCSRM) Floodwall - Phase 1 Project. The proposed project plans are enclosed.
