PROPOSED LOCAL STREET STANDARDS <br /> The Eugene Local Street Plan proposes a broader range of local street types and include narrower <br /> street cross sections than are currently allowed. Local streets which are as narrow as possible <br /> have several benefits to the community. <br /> * Narrow streets costs less to build and maintain. Less road base is needed and less <br /> surface area is paved. This results in lower materials and labor costs. City of Eugene <br /> staff estimates that an 8' reduction in local street width results in a 10% reduction in <br /> paving, sidewalk, and finishing costs. <br /> * Narrow streets reduce the negative impacts of stormwater runoff. Paved streets <br /> produce impervious surfaces which prevent the filtration of stormwater into the ground. <br /> Therefore, streets increase the volume of stormwater runoff, which can cause flooding, <br /> erosion, and habitat destruction, as well as reducing the groundwater supply. Excess <br /> paving also causes increased pollution of groundwater as a result of contaminants from <br /> the roadway surface entering the storm water system. The City of Eugene Stormwater <br /> Management Program recognizes reduced street widths as a means of reducing the <br /> volume of runoff in the Technical Memorandum #1: Residential Street Standards, <br /> published in March, 1995. <br /> * Narrow streets reduce the negative environmental impacts of street construction. A <br /> narrow street cross section will help minimize environmental impacts by requiring less <br /> land than a wider street. For improvements on existing streets, narrow widths will reduce <br /> the need to remove existing plants and trees. <br /> * Narrow streets encourage more efficient land use. The land saved by using narrow <br /> street designs can be used for other purposes including housing, landscaping and open <br /> spaces. <br /> * Narrow streets increase traffic safety. Narrow street designs will discourage the use of <br /> local streets by through traffic and help reduce traffic volumes and speeds. This will help <br /> to create quiet residential streets with low traffic volumes and speed. According to <br /> Residential Streets. published in 1990 by the American Society of Civil Engineers, the <br /> National Association of Homebuilders, and the Urban Land Institute, "Excessive <br /> widths...encourage greater vehicle speeds." Lower vehicle speeds will also reduce the <br /> severity of pedestrian- automobile accidents. According to the Center for Urban <br /> Transportation Research, approximately 55% of accidents are fatal to the pedestrian when <br /> vehicle speeds are 30 mph and over, while only 5% are fatal to the pedestrian when <br /> vehicle speeds are 20 mph or lower. . <br />
