WHEREAS, the Legislature of the State of Florida has delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. NOW, THEREFORE, BE IT ORDAINED by the City Council of the City of Cape Canaveral, Brevard County, Florida, as follows: SECTION 1. Chapter 624, Flood Damage Prevention, of the Code of Ordinances of the City of Cape Canaveral, Florida, is hereby repealed in its entirety and replaced with the following: CHAPTER 624 FLOOD DAMAGE PREVENTION Article 1.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, floodproofed, or otherwise unprotected from flood damages. Sec. 624.02 Statement of Purpose. It is the purpose of this ordinance 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; ORDINANCE NO. 6 -87 PAGE 1 OF 16 MICROFILMED JUNE 8 (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 accomodation of flood waters; (D) Control filling, grading, dredging and other development which may increase erosion or flood damage, and; (E) Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands. Sec 624.03 Objectives. The objectives of this chapter are: (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; and (G) To insure that potential home buyers are notified that property is in a flood area. Article 2. Definitions Sec. 624.07 Definitions. Unless specifically defined below, words or phrases used in this chapter shall be interpreted so as to give them the meaning they have in common usage and to give this chapterits most reasonable application. Addition (to an existing building) means any walled and roofed expansion to the perimeter of a building in which the addition is connected by a common load- bearing wall other than a fire wall. Any walled and roofed addition which is connected by a fire wall or is separated by independent perimeter load - bearing walls is new construction. Appeal means a request for a review of the City of Cape Canaveral's interpretation of any provision of this ordinance or a request for a variance. ORDINANCE NO. 6 -87 PAGE 2 OF 16 MICROFILMED JUNE 89 Area of Shallow Flooding means a designated AO or VO Zone on a community's Flood Insurance Rate Map (FIRM) with base flood depths from one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate, and where velocity flow may be evident. Area of Special Flood Hazard is the land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year. Base Flood means the flood having a one percent chance of being equaled or exceeded in any given year. Basement means that portion of a building having its floor subgrade (below ground level) on all sides.' Breakaway Wall means a wall that is not part of the structural support of the building and is intended through its design and construction to collapse under specific lateral loading forces without causing damage to the elevated portion of the building or the supporting foundation system. Building means any structure built for support, shelter, or enclosure for any occupancy or storage. Coastal High Hazard Area means the area subject to high velocity waters caused by, but not limited to, hurricane wave wash. The area is designated on a FIRM as Zone V1 - 30, VE or V. Development means any man -made change to improved or unimproved real estate, including, but not limited to, buildings or other structures, mining, dredging, filling, grading, paving, excavating, drilling operations, or permanent storage of materials. Elevated Building means a non - basement building built to have the lowest floor elevated above the ground level by means of fill, solid foundation perimeter walls, pilings, columns (posts and piers), shear walls, or breakaway walls. Flood or Flooding means a general and temporary condition of partial or complete inundation of normally dry land areas from the overflow of inland or tidal waters; and /or the unusual and rapid accumulation or runoff of surface waters from any source. Flood Hazard Boundary Map (FHBM) means an official map of a community, issued by the Federal Emergency Management Agency, where the boundaries of the areas of special flood hazard have been defined as Zone A. Flood Insurance Rate Map (FIRM) means an official map of a community, on which the Federal Emergency Management Agency has delineated both the areas of special flood hazard and the risk premium zones applicable to the community. Flood Insurance Study is the official report provided by the Federal Emergency Management Agency. The report contains flood profiles, as well as the Flood Boundary Floodway Map and the water surface elevation of the base flood. ORDINANCE NO. 6 -87 PAGE 3 OF 16 MICROFIL ED JUNE 89 Floodway means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. Floor means the top surface of an enclosed area in a building (including basement), i.e., top of slab in concrete slab construction or top of wood flooring in wood frame construction. The term does not include the floor of a garage used solely for parking vehicles. Functionally Dependent Facility means a facility which cannot be used for its intended purpose unless it is located or carried out in close proximity to water, such as a docking or port facility necessary for the loading and unloading of cargo or passengers, shipbuilding, ship repair, or seafood processing facilities. The term does not include long -term storage, manufacture, sales, or service facilities. Highest Adjacent Grade means the highest natural elevation of the ground surface, prior to construction, next to the proposed walls of a structure. Mangrove Stand means an assemblage of mangrove trees which is mostly low trees noted for a copious development of interlacing adventitious roots above the ground and which contain one or more of the following species: black mangrove (Avicennia nitida); red mangrove (Rhizophora mangle); white mangrove (Languncularia racemosa); and buttonwood (Conocarpus erecta). Mean Sea Level means the average height of the sea for all stages of the tide. It is used as a reference for establishing various elevations within the flood plain. For purpose of this ordinance, the term is synonymous with National Geodetic Vertical Datum (NGVD). Manufactured Home means a structure, transportable in one or more sections, which is built on a permanent chassis and designed to be used with or without a permanent foundation when connected to the required utilities. The term also includes park trailers, travel trailers, and similar transportable structures placed on a site for 180 consecutive days or longer and intended to be improved property. National Geodetic Vertical Datum (NGVD) as corrected in 1929 is a vertical control used as a reference for establishing varying elevations within the flood plain. New Construction means structures for which the "start of construction" commenced on or after the effective date of this ordinance. Sand Dunes means naturally occurring accumulations of sand in ridges or mounds landward of the beach. ORDINANCE NO. 6 -87 PAGE 4 OF 16 MICROFILMED JUNE 89 Start Of Construction (for other than new construction or substantial improvements under the Coastal Barrier Resources Act (P. L. 97 -348), includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, or improvement was within 180 days of the permit date. The actual start means the first placement of permanent construction of a structure (including a manufactured home) on a site, such as the pouring of slabs or footings, installation of piles, construction of columns, or any work beyond the stage of excavation or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and /or walkways; nor does it include excavation for a basement, footings, piers or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. Structure means a walled and roofed building that is principally above ground, a manufactured home, a gas or liquid storage tank, or other man -made facilities or infrastructures. Substantial Improvement means any combination of repairs, reconstruction, alteration, or improvements to a structure, taking place during the life of a structure, in which the cumulative cost equals or exceeds fifty percent of the market value of the structure. The market value of the structure should be (1) the appraised value of the structure prior to the start of the initial repair or improvement, or (2) in the case of damage, the value of the structure prior to the damage occuring. For the purposes of this definition, "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include any project for improvement of a structure required to comply with existing health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions. Variance is a grant of relief from the requirements of this ordinance which permits construction in a manner otherwise prohibited by this ordinance where specific enforcement would result in unnecessary hardship.

(F) Upon consideration of the factors listed above, and the purposes of this ordinance, the Zoning Board of Adjustment may attach such conditions to the granting of variances as it deems necessary to further the purposes of this ordinance. ORDINANCE NO. 6 -87 PAGE 9 OF 16 MICROFILMED JUTE 89 (G) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. (H) Conditions for Variances: (1) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief; and in the instance of a historical building, a determination that the variance is the minimum necessary so as not to destroy the historic character and design of the building. (2) Variances shall only be issued upon (1) a showing of good and sufficient cause and (2) a determination that failure to grant the variance would result in exceptional hardship, and; (3) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisance, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances. (3) Any applicant to whom a variance is granted shall be given written notice specifying the difference between the base flood elevation and the elevation to which the structure is to be built and stating that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation. (4) The Building Official shall maintain the records of all appeal actions and report any variances to the Federal Emergency Management Agency upon request. Article 5. Provisions for Flood Hazard Reduction Sec. 624.26 General Standards. In all areas of special flood hazard the following provisions shall apply: (A) New construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure; (B) Manufactured homes shall be anchored to prevent flotation, collapse, or lateral movement.

This standard shall be in addition to and consistent with applicable state requirements for resisting wind forces. (C) New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage; (D) New construction or substantial improvements shall be constructed by methods and practices that minimize flood damage; ORDINANCE NO. 6 -87 PAGE 10 OF 16 MICROFILMED JUNE 89 (E) Electrical, heating, ventilation, plumbing, air conditioning equipment, and other service facilities shall be designed and /or located so as to prevent water from entering or accumulating within the components during conditions of flooding. (F) New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system; (G) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters; (H) On -site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding, and; (I) Any alteration, repair, reconstruction or improvements to a structure which is in compliance with the provisions of this ordinance, shall meet the requirements of "new construction" as contained in this ordinance. Sec. 624.27 Specific Standards. In all areas of special flood hazard where base flood elevation data have been provided, as set forth in Sec. 624.10 or Sec. 624.21, the following provisions are required: (A) Residential Construction. New construction or substantial improvement of any residential structure shall have the lowest floor, including basement, elevated no lower than one (1) foot above the base flood elevation. Should solid foundation perimeter walls be used to elevate a structure, openings sufficient to facilitate the unimpeded movements of flood waters shall be provided in accordance with standards of Sec. 624.27. (B) Non - Residential Construction. New construction or substantial improvement of any commercial, industrial, or non - residential structure shall have the lowest floor, including basement, elevated no lower than one (1) foot above the level of the base flood elevation. Structures located in all A -zones may be flood - proofed in lieu of being elevated provided that all areas of the structure below the required elevation are water tight with walls substantially impermeable to the passage of water, and use structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certification shall be provided to the official as set forth in Sec. 624.20. (C) Elevated Buildings. New construction or substantial improvements of elevated buildings that include fully enclosed areas formed by foundation and other exterior walls below the base flood elevation shall be designed to preclude finished living space and designed to allow for the entry and exit of floodwaters to automatically equalize hydrostatic flood forces on exterior walls. ORDINANCE NO. 6 -87 PAGE 11 OF 16 MICROFILMED JUNE 89 (1) Designs for complying with this requirement must either be certified by a professional engineer or architect or meet the following minimum criteria: (a) Provide a minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding; (b) The bottom of all openings shall be no higher than one foot above grade; and, (c) Openings may be equipped with screens, louvers, valves or other coverings, or devices provided they permit the automatic flow of floodwaters in both directions. (2) Electrical, plumbing, and other utility connections are prohibited below the base flood elevation; (3) Access to the enclosed area shall be the minimum necessary to allow for parking of vehicles (garage door) or limited storage of maintenance equipment used in connection with the premises (standard exterior door) or entry to the living area (stairway or elevator); and (4) The interior portion of such enclosed area shall not be partitioned or finished into separate rooms. (D) Floodways. Located within areas of special flood hazard established in Sec. 624.10 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles and has erosion potential, the following provisions shall apply: (1) Prohibit encroachments, including fill, new construction, substantial improvements and other developments unless certification (with supporting technical data) by a registered professional engineer is provided demonstrating that encroachments shall not result in any increase in flood levels during occurrence of the base flood discharge; (2) If Sec. 624.27 is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions; (3) 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. (E) Coastal High Hazard Areas (V Zones). Located within the areas of special flood hazard established in Sec. 624.10 are areas designated as Coastal High Hazard areas. These areas have special flood hazards associated with wave wash, therefore, the following provisions shall apply: ORDINANCE NO. 6 -87 PAGE 12 OF 16 MICROFILMED JUNE 89 (1) All buildings or structures shall be located landward of the reach of the mean high tide; (2) 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 elevation level, with all space below the lowest supporting member open so as not to impede the flow of water. Open lattice work or decorative screening may be permitted for aesthetic purposes only and must be designed to wash away in the event of abnormal wave action and in accordance with Sec. 624.27; (3) All buildings or structures shall be securely anchored on pilings or columns; (4) 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 recurrence interval (one percent annual chance flood). (5) A registered professional engineer or architect shall certify that the design, specifications and plans for construction are in compliance with the provisions contained in Sec. 624.27 of this ordinance. (6) There shall be no fill used as structural support. Non - compacted fill may be used around the perimeter of a building for landscaping /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 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 ORDINANCE NO.. 6 -87 PAGE 13 OF 16 MICROFILMED JUNE 89 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. (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 Elevations and /or Floodways. Located within the areas of special flood hazard established where small streams exist but where no base flood data have been provided or where no floodways have been provided, the following provisions apply: (A) No encroachments, including fill material or structures shall be located within a distance of the stream bank equal to one -half times the width of the stream at the top of bank or twenty feet each side from top of bank, whichever is greater, unless certification by a registered professional engineer is provided demonstrating that such encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge. (B) New construction or substantial improvements of structures shall be elevated or flood - proofed to elevations established in accordance with Sec. 624.21. 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; ORDINANCE NO. 6-87 PAGE 14 OF 16 1 MICROFILMED JUNE 89 (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 acres. Sec. 624.30 Standards for Areas of Shallow Flooding (AO) Zones. Located within the areas of special flood hazard 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 structures 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 structures 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. ORDINANCE NO. 6 -87 PAGE 15 OF 16 MICROFILMED JUNE 89 SECTION 2.
