The term "levee" does not include—
(i) a roadway or railroad embankment that is not integral to the performance of a flood damage reduction system;

(F) a flood damage reduction channel.
The term "levee system" means 1 or more levee segments, including all levee features that are interconnected and necessary to ensure protection of the associated leveed areas—
(A) that collectively provide flood damage reduction to a defined area; and
(B) the failure of 1 of which may result in the failure of the entire system.
The term "national levee database" means the levee database established under section 3303 of this title.
The term "participating program" means a levee safety program developed by a State, regional district, or Indian tribe that includes the minimum components necessary for recognition by the Secretary.
The term "regional district" means a subdivision of a State government, or a subdivision of multiple State governments, that is authorized to acquire, construct, operate, and maintain projects for the purpose of flood damage reduction.
The term "rehabilitation" means the repair, replacement, reconstruction, removal of a levee, or reconfiguration of a levee system, including a setback levee, that is carried out to reduce flood risk, increase resiliency to extreme weather events, or meet national levee safety guidelines.
The term "rehabilitation" includes improvements to a levee in conjunction with any repair, replacement, reconstruction, or reconfiguration.
The term "risk" means a measure of the probability and severity of undesirable consequences.
The term "State" means—
