The general purpose of this Division is to establish regulatory requirements for land development and land disturbing activities within the city in order to minimize the threats to public health, safety, public and private property, and natural resources from construction site erosion and post-construction stormwater runoff. The following performance goals are established for all development under this Division:
(A) Meet minimum impact design standards (MIDS) performance goals;
(B) Assist in meeting construction stormwater general permit requirements;
(C) Assist in meeting total maximum daily load (TMDL) plan wasteload allocations for impaired waters through quantification of load reductions;
(D) Protect life and property from dangers associated with flooding and maintain or decrease the incidence and levels of flooding;
(E) Protect public and private property and natural resources from damage resulting from stormwater runoff and erosion;
(F) Ensure the annual stormwater runoff rates and volumes from post development site conditions mimic and/or reduce the annual runoff rates and volumes from predevelopment site conditions;
(G) Minimize the generation of stormwater runoff and maximizes pervious areas for stormwater treatment;
(H) Protect water quality from pollutant loadings of sediment, suspended solids, nutrients, heavy metals, toxins, debris, bacteria, pathogens, biological impairments, thermal stress, and other pollutants;
(I) Promote infiltration and groundwater recharge;
(J) Provide vegetated corridors (buffers) to protect water resources from development;
(K) Protect functional values of all types of natural waterbodies (e.g., rivers, streams, wetlands, lakes, seasonal ponds); and
(L) Protect, sustain or enhance biodiversity (native plant and animal habitat) and support riparian ecosystems.
