<br />AVOIDANCE ALTERNATIVES <br /> <br />No-Build Alternatives <br />This project is intended to complete a trail system designed to mitigate a clear risk to <br />pedestrians and bicyclists accessing the many destinations located along Main Street <br />(CSAH 14) and Centerville Road, including Centerville Elementary School. If this <br />project is not undertaken, the trail system will remain incomplete and safety issues <br />will not be addressed. The risk of injury would remain and continue to increase as the <br />City population and traffic grows. <br /> <br />Design/Construction Alternatives <br /> <br />Completing the existing trail with on-road segments would involve widening the <br />roadway shoulder and utilizing it for the trail. Since portions of an off-road trail <br />already exist, such an option would create a disjointed combination of on-road and <br />off-road segments. Also, due to the use of the proposed trail by elementary school <br />children and the increasing traffic volumes on Main Street (CSAH 14) and Centerville <br />Road, little increase in safety would be gained. Therefore, this alternative was not <br />selected. <br /> <br />Location Alternatives <br />Since segments of the trail system currently exist, constructing the trails in new <br />locations would leave the existing portions the trail system disconnected. Aligning the <br />trail parallel to City and County roadways will utilize existing right of way and <br />minimize SEE impacts. <br /> <br /> <br />Wetland ID # A <br />Wetland ID # B <br />Wetland ID # C <br />Wetland ID # D <br />Wetland ID # E <br />Wetland ID # F <br />Wetland ID # G <br />Wetland ID # H <br />Wetland ID # I <br />Wetland ID # J <br />Wetland ID # K <br />Total, acres <br /> <br />SP 02-090-01 <br />Wetland Assessment <br />March 2009 <br /> <br />AVOIDANCE ALTERNATIVES <br /> <br />Anticipated Encroachment per Alternative, acres <br />No Build <br />Alternative <br />o <br />o <br />o <br />o <br />o <br />o <br />o <br />o <br />o <br />o <br />o <br /> <br />Alternative # 1 <br /> <br />Alternative # 2 <br /> <br />o <br />o <br />0.02 <br />o <br />o <br />o <br />0.08 <br />o <br />o <br />o <br />o <br />0.1 <br /> <br />o <br />0.02 <br />o <br />0.08 <br />0.04 <br />0.06 <br />0.16 <br />o <br />o <br />o <br />0.01 <br />0.37 <br /> <br />Page 2 of 5 <br />
