Alteration Request vs. Letter of No Objection Request

An alteration request is required for levee system alterations by commercial interests (3rd Party)

A Letter of No Objection (LNO) request is required for levee system alterations by the Local Sponsor.

Both requests have to be reviewed by the local sponsor and written approval from the local sponsor provided to USACE in order to formally initiate USACE review.

Additional Levee Safety Program Authority

Local Cooperation Agreements require a Local Sponsor to operate and maintain their levee system in accordance with regulations prescribed by the Secretary of the Army (See 33 C.F.R. 208.10)
