impacts upon local and regional water resources diminishing the quality of public health, safety, public and private property, and natural resources of the City. Specifically, uncontrolled construction site erosion and storm water runoff can: (1) Threaten public health, safety, property, and general welfare by increasing runoff volume peak flood flows, and overburdening storm sewers, drainage ways, and other storm drainage systems; (2) Diminish the capacity of lakes and streams to support fish, aquatic life, recreational, and water supply uses by increasing pollutant loadings of total sediment, suspended solids, nutrients, heavy metals, bacteria, pathogens, and other urban pollutants; (3) Degrade physical stream habitat by increasing stream bank erosion, increasing stream bed scour, diminishing groundwater recharge, diminishing stream base flows, and increasing stream temperatures; (4) Undermine floodplain management efforts by increasing the incidence and levels of flooding; (5) Alter wetland communities by changing wetland hydrology and increasing pollutant loading; and (6) Generate airborne particulate concentrations that are health threatening or may cause other damage to property or the environment. 150.282 PURPOSE. (A) The general purpose of this ordinance is to set forth regulatory requirements for land development and land disturbing activities aimed at minimizing threats to public health, safety, public and private property and natural resources within the City from construction site erosion and post -construction storm water runoff. Specific purposes are to establish performance standards that will: (1) Protect life and property from dangers associated with flooding; (2) Protect public and private property and the natural resources from damage resulting from runoff and construction site erosion; (3) Protect functional values of all types of natural water bodies (e.g., rivers, streams, wetlands, lakes, seasonal ponds); (4) Sustain or enhance biodiversity (native plant and animal habitat) and support riparian ecosystems; (5) Protect water quality from nutrients, heavy metals, bacteria, pathogens, debris, thermal stress, and other urban pollutants; (6) Promote infiltration and groundwater recharge; (7) Regulate storm water runoff volumes and peak rates for land development and land disturbing activities;
