The wetlands will be protected by erosion control <br />measures and sedimentation traps during the con- <br />struction and thereafter until the turf is esta- <br />blished. The wetlands may be used as a natural <br />drainage basin for storm water runoff from the <br />proposed site. Exhibit 8-2 shows the location of <br />the wetlands. <br />8.2.10. Flood Plains <br />The proposed airport development project is not <br />subject to flood plains. The Mississippi River <br />approximately 3000 feet south of the project has a <br />regional flood plain of 848+ and the airport site <br />elevation is approximately 870.0. <br />8.2.11. Prime and Unique Farmland <br />A portion of the site to be acquired is used for <br />crops such as corn and soy beans. However, these <br />fields have not been determined to be prime or <br />unique farmland in the area. <br />8.2.12. Energy Supply and Natural Resources <br />Additional energy resources will be needed during <br />the construction and during the operation of the <br />facilities. Fuel usage will increase by virtue of <br />increased air traffic. Paving the runway, taxiway <br />and parking lots will require use of asphalt and <br />mineral material. The mineral material for aggre- <br />gate base and asphalt cement are mined within a 15 <br />mile radius of the site. Fuel for aircraft will be <br />available on the site. The overall effects of <br />airport development will be negligible. <br />8.2.13. Solid Waste Impacts <br />The proposed site will produce small quantities of <br />solid waste materials. Solid and recoverable oils <br />will be recycled or disposed as regulations <br />require. The landfill site is shown on Exhibit 8-2 <br />in the Appendix. <br />8-10 <br />
