In order to accomplish its purposes, this chapter includes methods and provisions to:
A. Restrict or prohibit uses which are dangerous to health, safety, and property due to water or erosion hazards which result in damaging increases in erosion, flood heights, or velocities;
B. Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
C. Control the alteration of natural floodplains, stream channels, and natural protective barriers which help accommodate or channel floodwaters;
D. Control filling, grading, dredging, and other development which may increase flood damage; and
E. Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards in other areas.
