Draft 9/29/14 <br />24. In general, there are no programs for stormwater maintenance outside the Eugene and <br />Springfield city limits, except for the Lane County roads program. State law limits <br />county road funds for stormwater projects to those located within the public right-of-way. <br />25. Filling in designated floodplain areas can increase flood elevations above the elevations <br />predicted by Federal Emergency Management Agency (FEMA) models, because the <br />FEMA models are typically based only on the extent of development at the time the <br />modeling was conducted and do not take into account the ultimate buildout of the <br />drainage area. This poses risks to other properties in or adjacent to floodplains and can <br />change the hydrograph of the river. <br />Policies <br />G.14 Improve surface and ground water quality and quantity in the metropolitan area by <br />developing regulations or instituting programs for stormwater to: <br />a.Increase public awareness of techniques and practices private individuals can <br />employ to help correct water quality and quantity problems; <br />b. Improve management of industrial and commercial operations to reduce negative <br />water quality and quantity impacts; <br />c. Regulate site planning for new development and construction to better manage <br />pre- and post-construction storm runoff, including erosion, velocity, pollutant <br />loading, and drainage; <br />d. Increase storage and retention and natural filtration of storm runoff to lower and <br />delay peak storm flows and to settle out pollutants prior to discharge into <br />regulated waterways; <br />e. Require on-site controls and development standards, as practical, to reduce off- <br />site impacts from stormwater runoff; <br />f.Use natural and simple mechanical treatment systems to provide treatment for <br />potentially contaminated runoff waters; <br />g.Reduce street-related water quality and quantity problems; <br />h. Regulate use and require containment and/or pretreatment of toxic substances; <br />i.Include containment measures in site review standards to minimize the effects of <br />chemical and petroleum spills; and <br />j. Consider impacts to ground water quality in the design and location of dry wells. <br />III-G-9 <br />Replaced October 31, 2008 <br />
