(A) The purpose of this chapter is to establish regulatory requirements for land development and land disturbing activities aimed at minimizing the threats to public health, safety, public and private property and natural resources within the city from construction site erosion and postconstruction stormwater runoff.
(B) Specifically, the ordinance establishes regulatory requirements that:
(1) Meet MIDS performance standards;
(2) Assist in meeting NPDES/SDS construction stormwater general permit requirements;
(3) Assist in meeting Total Maximum Daily Load (TMDL) plan waste load allocations for impaired waters through quantification of load reductions;
(4) Assist in meeting policies and performance standards of the Middle St. Croix Water Management Organization (MSCWMO) and Valley Branch Watershed District (VBWD);
(5) Protect life and property from dangers associated with flooding;
(6) Protect public and private property and natural resources from damage resulting from stormwater runoff and erosion;
(7) Ensure site design minimizes the generation of stormwater runoff and maximizes pervious areas for stormwater treatment within the context of the allowable use;
(8) Provide a single, consistent set of performance goals that apply to all developments;
(9) Protect water quality from pollutant loadings of sediment, suspended solids, nutrients, heavy metals, toxics, debris, bacteria, pathogens, biological impairments, thermal stress and other pollutants;
(10) Promote infiltration and groundwater recharge;
(11) Provide vegetated corridors (buffers) to protect water resources from development;
(12) Protect functional values of all types of natural waterbodies (e.g, rivers, streams, wetlands, lakes, seasonal ponds); and
(13) Sustain or enhance biodiversity (native plant and animal habitat) and support riparian ecosystems.
