Notice of Floodplain Encroachment for the Proposed Development at Cincinnati Municipal/Lunken Field Airport, Cincinnati, OH The Cincinnati Municipal/Lunken Field Airport (LUK) has a proposed hangar development project that would include the construction of a hangar, apron, taxilane, access road, parking lot and the removal and relocation of existing fuel tanks. The hangar and related development components are being constructed to handle the existing demand for hangar space at the Airport. The fuel tanks are being removed or relocated in preparation for the proposed new hangar development. The environmental review, consultation, and other actions required by applicable federal environmental laws for this project have been carried out according to FAA Order 1050.1G. Per Order 1050.1G and Executive Order 11988, Floodplain Management, LUK and the Federal Aviation Administration (FAA) have determined the proposed project is located within the 100-year floodplain. Although the proposed project would occur within a 100-year floodplain, the project would not change the flow of water or the airports ability to manage flood waters as the proposed project would tie into existing drainage infrastructure and drainage basin, both components of the existing airport-wide stormwater management system. Therefore, impacts on the floodplain are anticipated to be negligible. The encroachment will not impact existing infrastructure, will not have adverse impacts to the floodplain's natural and beneficial values, will not have a high probability of loss of human life, safe airport operations will not be affected, and aircraft services will not be interrupted.
