It is the purpose of this Subpart A to promote public health, safety, and general welfare and to minimize public and
private losses due to flood conditions within flood prone areas by provisions designed to:
Restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion
hazards or that result in increases in erosion, flood heights or velocities;
Require that uses vulnerable to floods, including facilities that serve such uses, be protected against
flood damage at the time of initial construction;
Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are
involved in the accommodation of floodwaters;
Control filling, grading, dredging, and all other development that may increase erosion or flood
damage; and
Prevent or regulate the construction of flood barriers that will unnaturally divert flood waters or which
may increase flood hazards to other lands.
