Areas designated as floodways or non-encroachment areas are located within the special flood hazard areas established in section 14-7. The floodways and non-encroachment areas are extremely hazardous areas due to the velocity of floodwaters that have erosion potential and carry debris and potential projectiles. In addition to the standards contained in sections 14-72 and 14-73, the following additional requirements shall apply to all development within such areas:
(1) No encroachments, including fill, new construction, substantial improvements and other developments shall be permitted unless:
a. Hydrologic and hydraulic analyses performed in accordance with standard engineering practice and presented to the floodplain administrator prior to issuance of a floodplain development permit demonstrate that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood; or
b. A conditional letter of map revision (CLOMR) has been approved by FEMA. A letter of map revision (LOMR) shall also be obtained upon completion of the proposed encroachment.
(2) If the provisions of this section are satisfied, all development shall comply with all applicable flood hazard reduction provisions of this article.
(3) Manufactured homes shall not be permitted except replacement manufactured homes in an existing manufactured home park or subdivision provided such development meets the anchoring and the elevation standards of section 14-73(3), as well as the no encroachment standard of subsection (1) of this section.
