In order to accomplish its purposes, this chapter includes methods and provisions
for:
(a)
Restricting or prohibiting uses which are dangerous to health, safety, and property
due to water or erosion hazards, or which result in damaging increases in erosion
or flood heights or velocities;
(b)
Requiring that uses vulnerable to floods, including facilities which serve such uses,
be protected against flood damage at the time of initial construction;
(c)
Controlling the alteration of natural floodplains, stream channels, and natural protective
barriers, which help accommodate or channel flood waters;
(d)
Controlling filling, grading, dredging, and other development which may increase flood
damage; and
(e)
Preventing or regulating the construction of flood barriers which will unnaturally
divert flood waters or which may increase flood hazards in other areas.
