The U.S. Army Corps of Engineers, Regional Planning and Environmental Center, in coordination with the City of Yukon, Oklahoma, has assessed the environmental impacts associated with the proposed construction of 1.35 miles of 12” water transmission pipeline, a water storage tank facility, and the replacement of sanitary sewer lines within the City of Yukon, Canadian County, Oklahoma. The project purpose is to improve the existing City of Yukon water supply distribution system to meet current and future demand, and to replace aging infrastructure in a 40-year old residential development. This is a Water Resource Development Authority Section 219 (Environmental Infrastructure) Project, which was authorized in the Consolidated Appropriations Act 2001 in Section 108. The City of Yukon, Oklahoma is the local sponsor for this proposed project.
