22 <br /> Draft 11-19-2013 <br /> Environmental Considerations for Access Management in the Study Area <br /> The Eno EDD — Environmental Map on page 11 depicts the topography, floodplains, <br /> and wetlands in the Study Area. These environmental considerations will in some <br /> locations provide challenges to the development of access management strategies <br /> recommended in the Study Area. <br /> Topography <br /> The Study Area has gradual changes in topography except in the northwest and <br /> northeast portions. Elevation with the Study Area ranges from 340 feet above sea level <br /> to 550 feet above sea level. Slopes are not particularly steep even in the vicinity of <br /> drainageways except in the previously noted portions. <br /> Floodplains <br /> Floodplains are located within the Study Area predominantly along Rhodes Creek. <br /> Floodplains indicate areas of past and potential future flooding. <br /> Wetlands <br /> Potential wetlands have also been identified throughout the Study Area by using the <br /> presence of Bottom land Hardwood Forest vegetation as an indicator for the presence of <br /> wetlands. Wetlands are generally unsuitable for development and normally require <br /> additional regulatory oversight and permitting by the U.S. Army Corps of Engineers. <br /> Environmental Benefit of Access Management <br /> From an environmental perspective, improved traffic flow afforded through an access <br /> management plan for the Eno EDD area could also translate into greater fuel efficiency <br /> and reduced vehicular emissions along the 1-85, US 70 and Old NC 10 corridors. <br /> 101 Page <br />
