Flood control, groundwater recharge, and pollutant reduction
shall be achieved through the use of stormwater management measures,
including green infrastructure best management practices (GI BMPs)
and nonstructural stormwater management strategies. GI BMPs and low-impact
development (LID) should be utilized to meet the goal of maintaining
natural hydrology to reduce stormwater runoff volume, reduce erosion,
encourage infiltration and groundwater recharge, and reduce pollution.
GI BMPs and LID should be developed based upon physical site conditions
and the origin, nature and the anticipated quantity, or amount, of
potential pollutants. Multiple stormwater management BMPs may be necessary
to achieve the established performance standards for water quality,
quantity, and groundwater recharge.
The purpose of this chapter is to establish minimum stormwater management requirements and controls for "major development," as defined below in Article
II.
