(A) Located within special flood hazard areas established in § 152.007 are areas designated as floodways.
(B) Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles, and erosion potential, the following provisions apply:
(1) (a) Encroachments in floodways are prohibited, including fill, new construction, substantial improvements, and other development, unless certification by a registered professional engineer is provided demonstrating that encroachments shall not result in any increase in flood levels and that the structural integrity of the development is not susceptible to the base flood velocities, bed scour and other physical mechanisms during the occurrence of the base flood discharge; and
(b) The certified demonstration must meet the procedures as set forth in § 152.030, and if approved by the Floodplain Administrator a development permit may be obtained.
(2) (a) The minimum setback from the edge of a floodway, or from the edge of a bank of a watercourse if no floodway is to be defined, shall be 20 feet; and
(b) Along reaches of streams or watercourses where hazards from eroding banks and/or channel meandering are considered by the district administrator to be severe, special engineering studies shall be made by the property owner or developer and requirements for setbacks from banks of streams or watercourses and/or other protection measures shall be established in accordance with findings that are concurred with by the Floodplain Administrator.
(3) No activity is permitted within a floodway that might cause lateral migration of waters at high or low stages or channel bed degradation or aggradation without a development permit.
