12-1-12: FLOODWAYS:
Floodways, located within areas of special flood hazard established in subsection 12-1-5B of this chapter, are areas designated as floodways. 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 shall apply;
   A.   Encroachments: Encroachments are prohibited, including fill, new construction, substantial improvements and other development unless certification by a professional registered engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels within the community during the occurrence of the base flood discharge.
   B.   New Construction, Substantial Improvements: If subsection A of this section is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section and sections 12-1-8 through 12-1-11 of this chapter. (Ord. 2717, 6-2-1987)
