7 Sec. 40. Department requirements.
8 (a) For the purposes of this Section:
9 "Base condition" means the current pre-permit top of levee
10 elevation profile, cross-sections, and levee centerline
11 alignment.
12 "Induced head" means:
13 (1) the change of the water surface profile; and
14 (2) any change in water elevations upstream or
15 downstream of the proposed improvement due to the change
16 of a base condition in levee height to a proposed
17 condition in levee height or encroachment.
18 "Proposed condition" means the change requested for State
19 and federal permits.
20 "Worst-case analysis" means flood events up to and
