Located within areas of special flood hazard (established in Section 9-53.2) are areas designated as floodways. Since a floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply:

(a) All encroachments are prohibited, including fill, new construction, substantial improvement, and other new development unless certification by a registered professional engineer is provided demonstrating that encroachments shall not result in any increase in the base flood elevation during the occurrence of the base flood discharge, and a CLOMR is issued by the Federal Emergency Management Agency.

(b) If subsection (a) of this section is satisfied, all new construction, substantial improvement, and other proposed new development shall comply with all other applicable flood hazard reduction provisions of this Division. (Ord. No. 1835 (NCS), § 1; Ord. No. 2037, § 12; Ord. No. 2383 (NCS), § 1.)
