§ 117-1. Purpose.

To provide for the health, safety, and general welfare of the public, and in response to the un-funded federal mandate, the city finds it necessary to adopt standards concerning erosion control, post-construction stormwater pollution prevention, and other provisions related to the regulation of earthmoving, excavation, and stormwater discharge. This chapter provides methods for controlling the introduction of pollutants into the municipal separate storm sewer system (MS4) in order to comply with the requirements of the National Pollutant Discharge Elimination System (NPDES) permit process. Specifically, the city has found that soil erosion resulting from nonagricultural land disturbing activities may cause a significant amount of sediment and other pollutants to be transported off-site to locations including adjacent properties, public streets, storm sewer structures, ditches, streams, wetlands, lakes and rivers. Furthermore, the proper installation and operation of stormwater management measures is necessary to ensure that soil erosion and stormwater quality issues do not arise after the completion of a land disturbing activity. The regulation of land disturbing activities will minimize the amount of sediment and other pollutants, resulting from soil erosion due to land disturbing activities, from being transported off site to adjacent public or private lands. It will also minimize erosion and stormwater quality issues that arise due to the longterm operation of the site after construction. This chapter applies to nonagricultural land disturbing activities, including industrial, commercial, institutional, residential, utility, and roadway development. The objectives of this chapter are:

(1)

To regulate the contribution of pollutants to the municipal drainageways, ponds, lakes, and other stormwater receivers.

(2)

To regulate the contribution of pollutants to municipal separate storm sewer system (MS4) by stormwater discharges by any user.

(3)

To reduce the potential negative impact of land disturbing activities on adjacent properties and the public at large.

(4)

To establish legal authority to carry out all inspection, surveillance and monitoring procedures necessary to ensure compliance with this chapter.

(5)

To minimize or reduce flooding, siltation, increases in stream temperature, and stream bank erosion and maintain the integrity of stream channels and to continue to enforce no net increase of stormwater runoff from newly developed sites.

(6)

To minimize increases in nonpoint source pollution caused by stormwater runoff from development, which could otherwise degrade local water quality.

(7)

To reduce soil erosion, and nonpoint source pollution, wherever possible, through stormwater management controls and to ensure that these management controls are properly maintained.
