• Floodplain - Doc Type: Educational/Technical/Reference Information

THE CITY/COUNTY DRAINAGE POLICY ALLOWS FOR THE USE OF DETENTION STORAGE OF
STORM W&.TER RUNOFF THAT IS COMPATIBLE WITH DRAINAGE BASIN STUDIES AND/OR OTHER
APPROVED STUDIES. REGIONAL DETENTION STORAGE FACILITIES SHALL BE UTILIZED
WHERE NECESSARY TO AFFORD PUBLIC SAFETY, PROVIDE FOR ECONOMIC DEVELOPMENT OF
BASIN DRAINAGE SYSTEMS OR TO PROTECT DOWNSTREAM DEVELOPMENTS FROM FLOOD DAMAGE.

1.6 Quality of Storm Water Runoff

Water poll uti on from urban areas common ly i nvo lves concentrati ons of trace
metals, organic materials, nutrients, salts, and sediment. Sediment production
from developed urban areas, however, is usually not a major problem; the
greatest sources of sediment from urban areas include erosion from new
construction and erosion of unstable channels. Sediment production in unstable
channel reaches can increase in areas where urban development causes 1 oca 1
increases in storm runoff rates. Detention storage ponds can decrease the
sediment load and debris in storm water runoff.

The Environmental Protection Agency (EPA) administers water pollution control
by provisions set forth in Section 208 of the Federal Water Pollution Control
Act Amendnents of 1972 (PL 92-500). Basin-wide "Section 208" plans prepared
for the City/County area in accordance with the EPA guidelines, help to:

o establish policies, programs and appropriate regulatory guidelines to
limit non-point pollution to ground and surface waters resulting from
urban growth, including irrigation systems, and

o abate existing pollutant loadings to the best extent possible, and

o integrate water quality considerations in the management of urban storm
water runoff and flood control.

THE CITY/COUNTY DRAINAGE POLICY SHALL REQUIRE PLANNING FOR WATER QUALITY
MANAGEMENT OF STORM wo.TER RUNOFF FROM DEVELOPMENTS. THE MANAGEMENT OF OVERALL
WATER QUALITY OF STORM DRAINAGE WILL REQUIRE DEVELOPERS TO SUBMIT AN EROSION
AND SEDIMENTATION CONTROL PLAN FOR ALL NEW DEVELOPMENT IN ACCORDANCE WITH
CRITERIA SET FORTH IN THIS MANUAL.
