Designated floodways are located within the special flood hazard areas established in section 13-1-3-2 of this chapter. 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:
A. Encroachment shall be prohibited, including fill, new construction, substantial improvements, storage of equipment or supplies, and any other development within the adopted regulatory floodway; unless it has been demonstrated through hydrologic and hydraulic analyses, performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge, and the federal emergency management agency has issued a conditional letter of map revision (CLOMR).
B. If subsection A of this section has been satisfied; all proposed new development and substantial improvements will comply with all other applicable flood hazard reduction provisions of this section 13-1-5. (Ord. 624, 2-14-2008)
