SECTION D. N�'THODS OF REDUCING �4LOOD LOSS�S
In order to accomplish its purposes, this ordinance uses the following
methods:
(1) Res�rict or prohibit uses th�t are dangerous to health, '
safety or property in times oi flood, or cause excessive
increases in flood 'neights or velocities;
(2) Require that us2s wlr.erai�le to fioo�s, including
facilities which serve sucn uses, be �rotected againsi
flood damuge at the time of initial cor,struction;
(3) Control the alterazior. of natural rlood plains, stream
channeis, and nati:ral p�otective barrie�s, which are
involved in the accomodation of flood wat�rs;
(4) Cor.z•rol ril.linr, g,ading, dredgi:�g and ocher
develop:,;ent which may increase iloon ua�«age;
(5) Prevent or reguiate �:ze conszruc'�ion of �lood barriers
whicn will unnaturally di�ert flood waters or which may
increase flood hazards to othe� lands.
