Construction, replacement, removal, or improvement of a crossing as defined in these rules will:
(A) Retain adequate hydraulic capacity and assure no net increase in the flood stage of the pertinent waterbody.
(B) Not change the existing flowline/gradient, or cause increased scour, erosion or sedimentation.
(C) Not adversely impact properties adjacent to the stream (examples include impeding drainage, inundation of land or structures in the two-year event or higher, and the like).
(D) Mimic channel bottom relative to upstream and downstream conditions. Lining channel bottoms with riprap should be avoided when possible.
(E) Maintain existing fish passage in the waterbody for fish species native to the area.
