Summary

The Secretary must make sure repairs or maintenance on a Federal jetty, pile dike, or breakwater are enough to keep the project doing what it was built to do. Work must protect any harbor or inland harbor tied to the project from projected changes in wave action or wave height, including changes from relative sea level change, over the useful life of the project. The Secretary must not call such repair or maintenance "major rehabilitation" if either: the Secretary finds that projected wave or sea level changes will reduce the structure’s ability to meet the project’s purpose and the work is needed to restore that ability; or regular, routine Federal maintenance was not carried out and, because of that lack of maintenance, the structure’s integrity is degraded or a pile dike has become disconnected.

(a)In general
In carrying out repair or maintenance activity of a Federal jetty, pile dike, or breakwater associated with an authorized navigation project, the Secretary shall, notwithstanding the authorized dimensions of the jetty, pile dike, or breakwater, ensure that such repair or maintenance activity is sufficient to meet the authorized purpose of such project, including ensuring that any harbor or inland harbor associated with the project is protected from projected changes in wave action or height (including changes that result from relative sea level change over the useful life of the project).

(B)such repair or maintenance activity is necessary to restore such functionality; or
(2)if the Secretary has not carried out regular and routine Federal maintenance activity at the jetty, pile dike, or breakwater and—
(A)the structural integrity of the jetty, pile dike, or breakwater is degraded as a result of a lack of such regular and routine Federal maintenance activity; or
