This community contains physical, biological, and social elements, each of which undergoes change from pressures exerted by both natural and man-made forces. Specifically, this Appendix defines the structure of the existing environmental community, its interrelationships, and the possible impacts on it may result from the implementation of some of the safety choices considered in this study. These safety choices are discussed in detail in Appendix E, Safety and Appearance Options. The Corps of Engineers, Buffalo District, awarded a contract for an assessment of the environment at Niagara Falls. The information in this Appendix is based largely on the report, Environmental Inventory and Assessment of the Options Considered by the American Falls International Board for Improved Safety at the American Falls, submitted to the Buffalo District by Michael Baker, Jr., Inc., in June 1974. Chapter G2 and G3 describe the existing environmental setting, which has been divided geographically into two areas. Chapter G2 discusses the Niagara Reservation and the surrounding Niagara Region. The Niagara Region has been arbitrarily defined as Niagara County, which is located on the United States side of the Niagara River. The land area of the Niagara Reservation borders the northern and southern flanks of the American Falls and the northern flank of the Horseshoe Falls and is under the jurisdiction of the Niagara Frontier State Park and Recreation Commission. Chapter G3 discusses the sites for possible safety improvement. The sites include the Prospect Point and Goat Island flanks of the American Falls and the Terrapin Point flank of the Horseshoe Falls. These flank
