Located within areas of special flood hazard established in § 151.11 are areas designated as floodways. Because the floodway is an extremely hazardous area, due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following requirements from 44 CFR Ch. 1 § 60.1 and A.R.S. § 48-3609B.4 apply:
(A) Prohibit encroachments, including fill, new construction, substantial improvements and other development, unless certification by a registered professional engineer or architect is provided, demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
