Structures that do not meet the setback may be permitted within
the bluffline setback area if they are set back at least 40 feet from
the bluffline and meet all of the following standards:
[a]
The structure does not protrude above the bluffline as viewed
from at or near the midline of the river or from 250 feet riverward
from the OHWM, whichever is less.
[b]
The structure is not located in a slope preservation zone.
[c]
The structure utilizes building materials that are earthtone
