11-1-3: METHODS OF REDUCING FLOOD LOSSES:
In order to accomplish its purposes, this chapter uses the following methods:
   A.   Restrict or prohibit uses that are dangerous to health, safety or property in times of flood, or cause excessive increases in 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 are involved in the accommodation of floodwaters;
   D.   Control filling, grading, dredging and other development which may increase flood damage; or
   E.   Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters or which may increase flood hazards to other lands. (2008 Code § 12-203)
