CHAPTER 624 FLOOD DAMAGE PREVENTION Article 1. Findings of Fact, Purpose and Objectives. Sec. 624.01 Findings of Fact. A. The flood hazard areas of the City of Cape Canaveral are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. B. These flood losses are caused by the cumulative effect of obstructions in floodplains causing increases in flood heights and velocities, and by the occupancy in flood hazard areas by uses vulnerable to floods or hazardous to other lands which are inadequately elevated, flood - proofed, or otherwise unprotected from flood damages. Sec. 624.02 Statement of Purpose. It is the purpose of this Chapter to promote the public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: A. Restrict or prohibit uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities. B. Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction. C. Control the alteration of natural floodplains, stream channels, and natural protective barriers which are involved in the accommodation of flood waters. D. Control filling, grading, dredging and other development which may increase erosion or flood damage. E. Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which 1 1 City of Cape Canaveral, Florida Ordinance No. 07 -92 Page 2 may increase flood hazards to other lands. are: Sec. 624.03 Objectives. The objectives of this Chapter A. To protect human life and health. B. To minimize expenditure of public money for costly flood control projects. C. To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public. D. To minimize prolonged business interruptions. E. To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains. F. To help maintain a stable tax base by providing for the sound use and development of flood prone areas in such a manner as to minimize flood blight areas. G.

The Building Official shall approve design plans for landscaping /aesthetic fill only after the applicant has provided an analysis by an engineer, architect, and /or soil scientist, which demonstrates that the following factors have been fully considered: a. Particle composition of fill material does not have a tendency for excessive natural compaction; b. Volume and distribution of fill will not cause wave deflection to adjacent properties; and c. Slope of fill will not cause wave run -up or ramping. 7. There shall be no alteration of sand dunes or mangrove stands which would increase potential flood damage. 8. Lattice work or decorative 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 breakaway, 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: a. No solid walls shall be allowed, and; b. Material shall consist of lattice or mesh screening only. City of Cape Canaveral, Florida Ordinance No. 07 -92 Page 15 9. If aesthetic lattice work or screening is utilized, such enclosed space shall not be designed to be used for human habitation, but shall be designed to be used only for parking of vehicles, building access, or limited storage of maintenance equipment used in connection with the premises. 10. Prior to construction, plans for any structures that will have lattice work or decorative screening must be submitted to the Building Official for approval. 11. Any alteration, repair, reconstruction or improvement to a structure shall not enclose the space below the lowest floor except with lattice work or decorative screening, as provided for in Sec. 624.27. 12. Prohibit the placement of manufactured homes (mobile homes), except in an existing manufactured home (mobile homes) park or subdivision. A replacement manufactured home may be placed on a lot in an existing manufactured home park or subdivision provided the anchoring standards of Sec. 624.26, and the elevation standards of Sec. 624.27 are met. Sec. 624.28 Standards for Streams without established Base Flood Elevation and /or Floodways. Located within the areas of special flood hazard established in Article 3, of this Chapter, where streams exist but where no base flood data has been provided or where base flood data has been provided without floodways, the following provisions apply: A. No encroachments, including fill material or structures shall be located within areas of special flood hazard, unless certification by a registered professional engineer is provided demonstrating that the cumulative effect of the proposed development, when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood more than one (1) foot at any point within the community. The engineering certification should be supported by technical data that conforms to standard hydraulic engineering principles. B. New construction or substantial improvements of buildings shall be elevated or flood - proofed to elevations established in accordance with Section 624.21(K). Sec. 624.29 Standards for Subdivision Proposals. A. All subdivision proposals shall be consistent with the need to minimize flood damage; B. All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage; C. All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hazards, and; D. Base flood elevation data shall be provided for subdivision proposals and other proposed development (including manufactured home parks and subdivisions) which is greater than the lesser of fifty lots or five (5) acres. Sec. 624.30 Standards for Areas of Shallow Flooding (AO) Zones. Located within the areas of special flood hazard City of Cape Canaveral, Florida Ordinance No. 07 -92 Page 16 established in text, are areas designated as shallow flooding areas. These areas have special flood hazards associated with base flood depths of one to three feet (1' - 3') where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate; therefore, the following provisions shall apply: A. All new construction and substantial improvements of residential buildings shall have the lowest floor, including basement, elevated to the depth number specified on the Flood Insurance Rate Map, in feet, above the highest adjacent grade. If no depth number is specified, the lowest floor, including basement, shall be elevated, at least two (2) feet above the highest adjacent grade. B. All new construction and substantial improvements of non - residential buildings shall: 1. Have the lowest floor, including basement, elevated to the depth number specified on the Flood Insurance Rate Map, in feet, above the highest adjacent grade. If no depth number is specified, the lowest floor, including basement shall be elevated at least two (2) feet above the highest adjacent grade, or; 2. Together with attendant utility and sanitary facilities be completely flood - proofed to or above that level so that any space below that level is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. Sec. 624.31 Severability. If any provision of this Chapter or the application thereof to any person or circumstance is held invalid, the invalidity shall not affect other provisions or applications of the Chapter which can be given effect without the invalid provision or application and to this end the provisions of this Chapter are declared severable. Sec. 624.32 Penalty. Any person violating any of the provisions of this Chapter shall be punished as provided in Sec. 801.05. SECTION 2. All portions of the Code in conflict herewith are hereby repealed. SECTION 3. This Ordinance shall take effect immediately upon its adoption.
