(d) When Base Flood Elevation (BFE) data is not available from a Federal, State, or other source as outlined above, the reference level shall be elevated or jloodproofed (nonresidential) to or above the Regulatory Flood Protection Elevation, as defined in Article 2. All other applicable provisions of Article S, Section B shall also apply. SECTION E. Reserved SECTION F. FLOODWAYSAND NON-ENCROACHMENT AREAS. Areas designated as floodways or non-encroachment areas are located within the Special Flood Hazard Areas established in Article 3, Section B. The floodways and non-encroachment areas are extremely hazardous areas due to the velocity ofjloodwaters that have erosion potential and carry debris and potential projectiles. The following provisions, in addition to standards outlined in Article S, Sections A and B, 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) it is demonstrated that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood, based on hydrologic and hydraulic analyses performed in accordance with standard engineering practice and presented to the Floodplain Administrator prior to issuance of floodplain development permit, or (b) a Conditional Letter of Map Revision (CLOMR) has been approved by FEMA. A Letter of Map Revision (LOMR) must also be obtained upon completion of the proposed encroachment. (c) In addition to the Article 5 Section F Subsection I, 1(a), 1(b), fill material graded to drain, provided such is protected against erosion. Any fill material on which a structure is to be located shall be extended at grade ten feet beyond the limits of the structure foundation, and shall have a side slope no steeper than two feet horizontal to one foot vertical. All material used as fill within the floodway and non-encroachment area fringe must be derived from adjacent floodway and non-encroachment area fringe and the same deeded parcel as that area being filled. The net result of borrow and fill within the floodway and non-encroachment area fringe area shall constitute no net loss to the flood storage capacity of the floodway and non-encroachment area fringe. A professional engineer must certify that no net loss of storage will occur as a result of the fill activity. (2) If Article 5, Section F(1) is satisfied, all development shall comply with all applicable flood hazard reduction provisions of this ordinance. (3) No manufactured homes shall be permitted, except replacement manufactured homes in an existing manufactured home park or subdivision, provided the following provisions are met: (a) the anchoring and the elevation standards of Article S, Section B(3); and 24
