<br />157.01. Findings . It is hereby determined that: <br />(A) Land development projects and associated increases in impervious cover alter the <br />hydrologic response of local watersheds and increase stormwater runoff rates and <br />volumes, flooding, stream channel erosion, and sediment transport and deposition; <br />and, <br />(B) This stormwater runoff contributes to increased quantities of water-borne <br />pollutants; and, <br />(B) Stormwater runoff, soil erosion and non-point source pollution can be controlled and minimized <br />through the regulation of stormwater runoff from development sites. Therefore, the City establishes this set of <br />water quality and quantity policies applicable to all surface waters to provide reasonable guidance for the <br />regulation of stormwater runoff for the purpose of protecting local water resources from degradation. It is <br />determined that the regulation of stormwater runoff discharges from land development projects and other <br />construction activities in order to control and minimize increases in stormwater runoff rates and volumes, soil <br />erosion, stream channel erosion, and non-point source pollution associated with stormwater runoff is in the <br />public interest and will prevent threats to public health and safety. <br /> <br />157.01. Definitions <br /> <br />The following words, terms and phrases, when used in this article, shall have the <br />meanings ascribed to them in this section, except where the context clearly indicates a <br />different meaning: <br /> <br />Bench is a relatively level step excavated into earth material on which fill is to be <br />placed. <br />Best Management Practices (BMP) are erosion control, sediment control and water quality management <br />practices that are most effective and practicable for means of controlling, preventing and reducing the <br />degradation of surface water as published by state or designated area-wide planning agencies. <br />Buffer means land that is used to protect adjacent lands and waters from\\development and more intensive land <br />uses. The land is kept in a natural state of trees, shrubs, and low ground cover and understory of plants and <br />functions to filter runoff, control sediment and nutrient movement, and protect fish and wildlife habitat. In areas <br />of agricultural use, the land may be used for less intensive agricultural purposes provided its function as a buffer <br />remains intact. <br />Channel means a natural or artificial watercourse with a definite bed and banks that conducts continuously or <br />periodically flowing water. <br />Common Plan of Development or Sale is a contiguous area where multiple separate and distinct land disturbing <br />activities may be taking place at different times, or on different schedules, but under one proposed plan. This <br />item is broadly defined to include design, permit application, advertisement or physical demarcation indicating <br />that land-disturbing activities may occur. <br />Detention facility is a temporary or permanent natural or man-made structure that provides for the temporary <br />storage of stormwater runoff. <br />Discharge is the release, conveyance, channeling, runoff or drainage of stormwater, including snowmelt, from a <br />construction or development site. <br />Filter strip is a vegetated section of land designed to treat runoff as overland sheet flow. It may be designed in <br />any natural vegetated form from a grassy meadow to a small forest. The dense vegetated cover facilitates <br />pollutant removal, reduces erosion and promotes infiltration. <br />Floodplain the channel or beds proper and the areas adjoining a wetland, lake or <br />413 |Page <br /> <br /> <br />
