§ 27-123. Purpose.

(a)

This article is enacted to protect, maintain and enhance the public health, safety, environment, and general welfare, and public and private property and infrastructure, by establishing minimum requirements and procedures to manage and control the adverse effects of post-construction stormwater runoff from new development and redevelopment in the City of Jackson, as required by and in accordance with the Federal Water Pollution Control Act, as amended (33 U.S.C. 1251 et seq.; the "Federal Act"), Michigan Act 451, Public Acts of 1994, as amended (the "Michigan Act"), Parts 31 and 41, the city's MS4 watershed general permit, the city's certificate of coverage, and other applicable local, state and federal laws and regulations.

(b)

Further, this article establishes minimum stormwater management provisions and requirements to accomplish purposes including, but not limited to, the following:

(1)

Achieve compliance with state and federal stormwater laws and regulations.

(2)

Establish a minimum treatment volume standard to minimize water quality impacts of post-construction stormwater runoff.

(3)

Establish channel protection criteria to minimize excess sediment and channel instability caused by increased flow rate and volume from post-construction stormwater runoff.

(4)

Protect natural infiltration and groundwater recharge rates in order to sustain ground water supplies and stream base flows.

(5)

Maintain natural drainage patterns and encourage the use of natural drainage systems and low impact development techniques.

(6)

Treat and release stormwater as close to the source of runoff as possible using minimal structures and maximizing reliance on natural processes.

(7)

Prevent or minimize the adverse impacts on water quality and channel stability caused by post-construction runoff by requiring implementation of appropriate stormwater management practices, methods, and facilities.

(8)

Recognize private responsibility to incorporate stormwater management systems into the early stages of site planning and design.

(9)

Provide requirements to ensure effective long-term operation and maintenance of stormwater management practices, methods, and facilities.

(10)

Establish recordkeeping requirements to document the implementation of and compliance with the post-construction stormwater runoff program established by this article, including documentation of stormwater management plans, operation and maintenance plans and agreements, and enforcement actions.

(11)

Facilitate achievement of the goals outlined in the Upper Grand River Watershed Master Plan.
