SECTION 2: Flood Plain and Wetlands Regulations
ARTICLE I - GENERAL REGULATIONS
Section 1.01: Purpose The purpose of this Ordinance is to
diminish threats to public health and safety caused by flood-
waters; reduce economic losses to individuals and the
community at large; enhance community economic objectives;
protect, conserve, and promote the orderly development of
land and water resources; prevent victimization and fraud;
and comply with the guidelines for the National Flood
Insurance Program as published by the U.S. Department of
Housing and Urban Development.
The following criteria and purposes are established for the
utilization and control of such flood plains and `ret.land areas:
(a) to consider flooding and drainage problems
as space allocation or land use problems and to
the degree practicable allocate the natural flood-
water storage space flood plains and wet
lands -- for this purpose.
(b) to use flood plains and wet lands only for land
use purposes which are compatible witty their
physical conditions thereby preventing the creation
of new flood and drainage problems.
�I
(c) '1'r� :avoid tFac iilere tsE, of lipstreatn,
stream, a,ld do%vtistream flood ri:;,:s by lare-
venting; inrreased run-off and a redLAributiu:i
of flood .v3ters.
(d) To preserve and possibly enhance tin quan-
tity of ground water supplies by maintaining
open and undisturbed prime natural ground
water recharge areas.
(e) To preserve and possibly enhance the quatity-
of ground and surface water resources by
helping to control excess infiltration into sani-
tary sewer :,ystems and by preventing the
location of septic systems and mixed fills in an
unfavorable physical environment.
(f) To preserve distinctive flood plain and wet
land flora and fauna.
(g) To consider flood plain and suet land areas
in density consideration in zoning and Sub-
division determinations.
(h) To improve the health, safety, and general
welfare -)f the people of Oak Brook and its
environs by lessening or avoiding hazards to
persons and damage to property resulting
from the accumulation or runoff of storm or
floodwaters.
(i) To preserve and possibly enhance the quality
of the existing surface water by allowing the
natural process of runoff and overbank flooding
to accomplish what nature intended and to
store floodwaters temporarily and to allow
particulate, dissolved solids, and organic
matter to settle, oxidize and digest out of the
floodwaters before returning to the main
strcamflow.
