§ 92-3. Purpose.

It is the purpose of this chapter to establish minimum stormwater management requirements and controls to accomplish, among others, the following objectives:

(1)

To minimize increased stormwater runoff rates and volumes from identified land development or redevelopment;

(2)

Minimize nonpoint source pollution;

(3)

To minimize the deterioration of existing watercourses, culverts and bridges, and other structures;

(4)

To encourage ground water recharge where geologically favorable conditions exist;

(5)

To maintain the ecological integrity of stream channels;

(6)

To minimize the impact of development upon streambank and streambed stability;

(7)

To control non-stormwater discharges to stormwater conveyances and reduce pollutants in stormwater discharges;

(8)

To preserve and protect water supply facilities and water resources by means of controlling increased flood discharges, stream erosion, and runoff pollution;

(9)

To reduce the adverse impact of changing land use on water bodies and, to that end, this ordinance establishes minimum standards to protect water bodies from degradation resulting from changing land use where there are insufficient stormwater management controls;

(10)

To ensure that storm drainage or stormwater BMPs are adequate to address stormwater management needs within a proposed development, and for protecting downstream landowners from flooding and degradation of water quality. The procedures, standards, and recommendations set forth in this ordinance and the State of Michigan Low Impact Development (LID) Manual are designed for these purposes; and

(11)

To ensure that all stormwater facilities necessary for a proposed development will have a responsible party, in perpetuity, for performing maintenance or for overseeing the performance of maintenance by a private entity, such as a property owners' association.
