Reduction of open space, removal of vegetative cover, and development that increases the <br /> amount of impervious surfaces (paved streets, roofs, parking lots) contribute significantly <br /> to increases in the peak volume (quantity) of urban storm runoff entering stormwater <br /> system and natural drainageways. <br /> <br /> Water pollution in the metropolitan area results from both "point sources" (municipal and <br /> industrial wastewater discharges) and "non-point sources" (pollutants such as oil, dust, <br /> and debris which are carried into streams by storm runoff). Water pollution is most acute <br /> in streams that have low water flow conditions during the summer months (such streams <br /> include Amazon Creek and the "Q" Street ditch). <br /> <br />93?. Offsetting measures can reduce the negative effects of urban development on water <br /> quality and quantity problems. Examples include on-site retention of stormwater, <br /> inclusion of landscaped "buffer strips" adjacent to new developments and conservation <br /> and improvement of streamside vegetation along water courses. <br /> <br /> The Willamette and McKenzie Rivers run through many jurisdictions, necessitating <br /> cooperative water management planning and consideration for downstream effects of <br /> actions taken by a single jurisdictionl <br /> <br />33-~-3.?~:~ The Eugene-Springfield area is currently in compliance with national standards for <br /> carbon monoxide. The region will continue to be in compliance with the carbon <br /> monoxide standard in the future. Vehicle fleet turnover and stricter emission controls on <br /> newer vehicles are factors that will contribute to lower emissions in the future. <br /> <br />Policies <br /> <br /> Springfield, Lane County, and Eugene shall consider downstream impacts when planning <br /> for urbanization, flood control, urban storm runoff, recreation, and water quality along the <br /> Willamette and McKenzie Rivers. <br /> <br />-24~.:~6. Local governments shall continue to monitor, to plan for, and to enforce applicable air <br /> and water quality standards and shall cooperate in meeting applicable federal, state, and <br /> local air and water quality standards. <br /> <br />-2-2C.2.'~Local governments shall continue to cooperate in developing and implementing programs <br /> necessary to meet air quality standards.
