Sec. 70-33. Regulatory floodways.
Floodways are administrative limits and tools used to regulate existing and future floodplain development. Located within SFHA 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:
(1) Encroachments are prohibited, including fill, new construction, substantial improvements and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed by a licensed Colorado Professional Engineer and in accordance with standard engineering practice that the proposed encroachment would not result in any increase (requires a no-rise certification) in flood levels within the city during the occurrence of the base flood discharge.
(2) If subsection (a) above is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of division 5 of this article.
(3) Under the provisions of Section 65.12, of the NFIR, the city may permit encroachments within the adopted regulatory floodway that would result in an increase in BFE, provided the city first applies for a CLOMR and floodway revision through FEMA.
