AMENDED ORDINANCE O-18-015
(3) Structural stormwater management practices shall be selected to accommodate the
unique hydrologic and geologic conditions of the site. Design computations must
document these conditions.
(4) Nonstructural management measures may reduce or eliminate the need for
structural BMPs to meet recharge, water quality, and peak discharge control
requirements. These techniques, shall include Runoff Prevention Methods
(RPMs), are encouraged and shall be designed in accordance with the guidelines
in the documents listed in Subsection I(1) above. These techniques may include
disconnection of rooftop and nonrooftop runoff, vegetated bio-cells and bio-
islands, infiltration edges, dividers, or islands, planters, and raingardens.
J. Allowable Non-Stormwater Discharges.
The following non-stormwater discharges are authorized provided it has been determined that
they are not significant contributors of pollutants to the MS4. If these discharges are identified
as significant contributors to the MS4, they must be addressed in the Illicit Discharge Detection
and Elimination minimum control measure described.
(1) Water line flushing:
(2) Landscape irrigation;
(3) Diverted stream flows;
(4) Rising ground waters:
(5) Uncontaminated ground water infiltration (as defined at 40 CFR 35.2005(20)):
