The proposed (Description of Minimization of Water two lane structure is a multiple span bridge with three spans (1 @55'(21 "), 1@70'(24"), 1@45'(21 ")) cored slab with 4' end bent caps. The proposed bridge will have deck drains, Quality Impacts) however they will not discharge over open water. Cutawhiskie Swamp is a FEMA limited detail study with non-encroachment widths established. Regulatory floodways are delineated on the FIRM and flood profiles have not been developed. This structure has been designed to have as little environmental and surface water impacts as possible. Velocities at jurisdictional features and wetlands are non-erosive with velocities under 2 feet per second.
