(A) Floodways located within SFHAs are extremely hazardous areas due to the velocity of floodwaters that carry debris, potential projectiles and erosion potential.
(B) The following provisions shall apply:
(1) Designate a regulatory floodway that will not increase the base flood level more than one foot;
(2) 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 in accordance with standard engineering practices that the proposed encroachment would not result in any increase greater than zero feet, unless a higher standard option is selected, in flood levels within the community during the occurrence of the base flood discharge;
(3) All new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of §§ 151.50 to 151.62 of this chapter; and
(4) Under the provisions of 44 C.F.R. § 65.12, Chapter 1 of the NFIP Regulations, a community may permit encroachments within the adopted regulatory floodway that would result in an increase in BFEs provided that the community first applies for a conditional FIRM and floodway revision through FEMA.
