Potentially suitable habitat for the smooth coneflower and Michaux's sumac was observed in the <br />forest canopy gaps and at the margins of the forest and adjacent fields. However, Catena <br />thoroughly examined these areas and found no individuals. <br />Catena's conclusions were that the project actions will have "No Effect" on any of the species <br />listed for Orange County. A copy of the Catena Group's report is included in Appendix D. <br />4.0 PREDICTED ENVIRONMENTAL EFFECTS OF PROJECT <br />4.1 Topography <br />The Paydarfar site has little level ground and has slopes ranging from less than 5 percent to about <br />10 percent, with a few small areas slightly steeper. A drainage feature diagonally crosses the <br />property from the northwest downward toward the southeast. <br />As shown on Exhibit B, the transfer station facilities will occupy most of the 10 -acre tract. Grades <br />and roadway turns will have to be set to accommodate use of the site by large collection trucks and <br />larger long -haul vehicles using the facility. Therefore, the topography of the site will have to be <br />re- shaped in accordance with the design and operational requirements of the transfer station. The <br />elevation of the overall site will not substantially change and efforts will be made to balance the <br />volume of cut and fill. Site grades will be set to match existing grades at the site boundaries and <br />surface water drainage patterns from the site will not greatly change. Careful design and <br />implementation of erosion control facilities will be made to limit sediment erosion from the site. <br />4.2 Soils <br />As discussed above, the topography of the site will need to be modified to construct a functional <br />transfer station. Although sampling and testing of the native Georgeville soils will be necessary, <br />these soils should be suitable for earthwork construction. According to the USDA soil survey <br />report, the depth to groundwater or rock is expected to be substantially greater than the depths of <br />excavation. In setting grades, efforts will be made to balance cut and fill volumes but some use of <br />off -site soils for fill may be necessary. <br />Best management practices (BMPs) will be used during construction to ensure that chemical <br />spillage is minimized, and soil is not contaminated. Long -term effects to soil in the area are not <br />expected due to the facility being fully- enclosed and facility policy will prohibit the long -term <br />storage of chemicals outside. <br />Environmental Assessment — Paydarfar Site <br />14 September 30, 2009 <br />
