§ 35-F105. Methods of Reducing Flood Losses.
(a)
In order to accomplish reduction of flood loss, this ordinance uses the following methods:
(1)
Restrictions or prohibitions to uses that are dangerous to health, safety or property in times of flood, or cause increases in flood heights or velocities;
(2)
Requiring that uses vulnerable to floods, including public facilities which serve such uses, be protected against flood damage at the time of initial construction;
(3)
Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwater s;
(4)
Preventing or regulating the construction of flood barriers which will unnaturally divert floodwater s or which may increase flood hazards to other lands.
(5)
Controlling development which would cause greater erosion or potential flood damage such as grading, dredging, excavation, and filling;
(6)
Control filling, grading, dredging and other development which may increase flood damage;
(7)
Imposing a regulatory 1% annual chance floodplain that requires using the ultimate development of the watershed to determine the 1% annual chance water surface elevations. New developments must be constructed above this elevation.
