Located within areas of special flood hazard are areas designated as floodways. Because the floodway is an extremely hazardous area due to the velocity of flood waters and erosion potential, the following standards shall apply in any floodway: a. Encroachments, including fill, new construction, substantial improvements and other developments, are prohibited unless certification, with supporting technical data, by a Florida registered professional engineer is provided demonstrating that the encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge; b.' All new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section; and c. The placement of manufactured homes is prohibited except irr an existing manufactured home park or subdivision; however, a replacement manufactured home may be placed on a lot in an existing manufactured home park or subdivision provided the anchoring standards and the elevation standards set forth herein are met.

Because these areas have special flood hazards associated with wave wash, the following standards are required: a. All buildings or structures shall be located landward of the coastal construction control line. b. All buildings or structures shall be elevated so that the bottom of the lowest supporting horizontal member (excluding pilings or columns) is located at or above the base flood elgvation level, with all space below the lowest supporting member open so as not to impede the flow of water. Breakaway walls may be permitted if designed to wash away in the event of abnormally high tides or wave action and in accordance with subparagraph h, below, C. All buildings or structures shall be securely anchored on pilings - or columns. d. All pilings and columns and the attached structures shall be anchored to resist flotation, collapse, and lateral movement due to the effect of wind and water loads acting simultaneously on all building components. The anchoring and support system shall be designed with wind and water loading values which equal or exceed the 100'-year mean occurrence interval (one per cent annual chance flood). e. A Florida registered professional engineer or architect shall certify r2 that the design, specifications and plans for construction are in compliance with the provisions of subparagraphs b, c and d of this paragraph. f. There shall be no f i 1 l used as structural support. Noncompacted f i 11 may be used around the perimeter of a building for landscaping or aesthetic purposes provided the fill will wash out from storm surge (thereby rendering the building free of obstruction) prior to generating excessive loading forces, - ; ramping effects, or wave deflection. The building official shall approve design plans for landscaping/aesthetic fill only after the applicant has provided an L analysis by an engineer, architect, or soil scientist which demonstrates that the following factors have been fully considered: 1. Particle composition of fill material does not have a tendency for excessive natural compaction; 2. Volume and distribution of fill will not cause wave deflection to f. adjacent properties; and 3. Slope of fill will not cause wave run-up or ramping. 13 In, mow. - .- .. • ..a ?e a s L :W ri.Y 3 " 4 • V7 1 .? S-. T-• :d i ' , ?d• S ,f'Y •i. ill: F{: :1. 'f, 'i .'.;j•, .??4Z't ?., .1.'>' >??

There shall be no alteration of sand dunes or mangrove stands which would increase potential flood damage. h. Nonsupporting breakaway walls, open latticework, or mesh screening shall be allowed below the base flood elevation provided they are not part of the structural support of the building and are designed so as to break away, under abnormally high tides or wave action, without damage to the structural integrity of the building on which they are to be used and provided the following design specifications are met: 1. Design safe loading resistance of each wall shall be not less than ten (10) nor more than twenty (20) pounds per square foot; or 2. If more than twenty (20) pounds per square foot, a Florida registered professional engineer or architect shall certify that the design wall collapse would result from a water load less than that which would occur during the base flood event, and the elevated portion of the building and supporting foundation system shall not be subject to collapse, displacement or other structural damage due to the effects of wind and water loads acting simultaneously on all building components during the base flood event. Maximum wind and water loading values to be used in this determination shall each have a one per cent chance of being equalled or exceeded in any given year (100-'year mean recurrence interval). i. If breakaway walls are utilized, such enclosed space shall 4F-x not be designed to be usable for human habitation but shall be designed to be usable only for parking of vehicles, building access or limited storage of maintenance equipment used in connection with the premises. j. Prior to construction, plans for any structures that will have breakaway walls shall mum be submitted to the building official for approval. k. Any alteration, repair, reconstruction or improvement to a structure shall not enclose the space below the lowest floor except with breakaway walls. 1. The placement of manufactured homes is prohibited except in an existing manufactured home park or subdivision; however, a replacement manufactured home may be placed on a lot in an existing manufactured home park or subdivision provided the anchoring standards and the elevations standards set forth herein are met.
