A preliminary identification, location and assessment of known historic and architectural resources located within a 1/2 mile corridor on either side of the Kansas River and its major tributaries (Wakarusa, Delaware, Big Blue, Smoky Hill, Saline and Solomon Rivers; and Vermillion and Soldier creeks) is presented. A total of 29 urban zones, 244 buildings, 98 bridges, 11 dams, 3 historical markers and 34 cemeteries of known or potential historical significance were identified within the project right-of-way. Two districts and twenty six structures and sites included in the National Register of Historic Places are located within the project area. The assessment recommends appropriate mitigation if construction activities occur at or adjacent to National Register sites. Evaluation and appropriate mitigation of construction impacts on known historic sites and urban zones of potential significance presented in the study, is recommended. A windshield survey to preliminarily identify historic sites and structures in rural areas to be impacted by construction followed by selected detailed inventories and assessments is recommended.
