Evaluation of Alternatives <br /> <br />Chapter V - Evaluation of Alternatives <br /> <br />Four factors were used to evaluate the alternatives: I) Impacts on the man-made <br /> <br />environment, the natural environment and the existing social structure; 2) Technical <br /> <br /> <br />considerations; 3) Project costs; and 4) Institutional requirements for project implementation. <br /> <br />The project impacts related to man-made environment, the natural environment and the <br /> <br />existing social structure are common to all of the alternatives, and are described below. The <br /> <br /> <br />technical, costs, and institutional requirements valY between alternatives and are described in <br /> <br /> <br />detail for each alternative. The following sectionG describe the project's output/yield, impacts, <br /> <br /> <br />institutional requirements and costs. Financial fe[isibility will be addressed for the selected <br /> <br /> <br />alternatives in Chapter VI. <br /> <br />A. Impacts <br /> <br />A.I Man-Made Environmental Impacts <br /> <br />There will not be any foreseen environmental impacts to existing dwelling units, <br /> <br /> <br />commercial facilities, or other structures in the project area, due to the developed alternatives. <br /> <br /> <br />There are no utilities or roadways that will have to be relocated for the project. The site access <br /> <br /> <br />road might have to be improved slightly for constrUction traffic. There are no additional lands <br /> <br />that would be inundated above the historical impoundment elevation 6918.7 (spillway crest). <br /> <br /> <br />Construction staging will be limited to the existing parking area located on the left abutment and <br /> <br /> <br />above the normal high water elevation within the reservoir. <br /> <br />A.2 Natural Environmental Impacts <br /> <br />A wetland and threatened/endangered species assessment was performed on June I, 2000. <br /> <br /> <br />The methodology utilized for determining potential jurisdictional waters of the U.S. followed the <br /> <br /> <br />U.S. Army Corps of Engineers (AECOE) WetlandS Delineation Manual. Hydric soils, <br /> <br /> <br />hydrophytic vegetation and signs of hydrology are the three parameters that must be present for <br /> <br /> <br />an area to be classified as jurisdictional. <br /> <br />Monument Lake Dam Feasibility Study <br /> <br />46 <br /> <br />BOYLE <br />
