A. All site designs shall establish storm water management practices to control the peak flow rates of storm water discharge associated with specified design storms and reduce the generation of storm water. These practices should seek to utilize previous areas for storm water treatment and to infiltrate storm water runoff from driveways, sidewalks, rooftops, parking lots, and landscaped areas to the maximum degree feasible.

B. All storm water runoff generated from new development shall not discharge untreated storm water directly into a jurisdictional wetland or local water body without adequate treatment. Where such discharges are proposed, the impact of the proposal on wetland functional values shall be assessed using a method acceptable to the city engineer. In no case shall the impact on functional values be any less than allowed by the Army Corp of Engineers (ACE) or the Department of Environmental Quality (DEQ) responsible for natural resources.

C. Storm water discharges to critical areas with sensitive resources may be subject to additional performance criteria or may need to utilize or restrict certain storm water management practices.

D. Storm water discharges from land uses or activities with higher potential pollutant loadings, known as hotspots, may require the use of specific structural BMPs and pollution prevention practices.

E. Prior to design, applicants are required to consult with the city engineer to determine if they are subject to additional storm water design requirements. [Code 2000 § 9-3a-15].
