Maxinun wind and water loading values to be used in this determination shall each have one (1) percent chance of being equalled or exceeded in any given year (100-year mean recurrence interval). If breakaway walls ere utilized, such enclosed space shall not be designed to be usable for human habitation but shail be designed to be usable only for parking of vehicles, building access or limited storage of maintenance equipment used in connection with the premises, Prior to construction, plans for any structures that will have breakaway wails must be submitted to the City Manager or his designee for approval. Any alteration, repair, reconstruction or improvement to a structure shall not enclose the space below the lowest floor except with breakaway walls, as provided for in Acticle 5, Seetion B (5) (h) and (i). Prohibit the placement of manufactured homes (wobile homes), except in an existing manufactured homes (manufactured hones) 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 Article 5, Section B (4) (e) and the elevation standards of Article 5, Section 8B (4) (b) are met. Standards for Streams without Established Base Floor Elevations and/or Tloodways. Located within the areas of special flood 4 nazard established in Article 3, Section B, where streans exist but _where no base flood data have been provided or where base flood data has been provided without flcodways, the following provisions apply: SECTION D. (1) Wo =encroachtents, including fill waterial 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 proposed development, will not increase the water surface elevation of the base Flood tore than one (1) foot at any point within the community. The enz,ineering certification shall be supported by technical data that conforms to standard hydraulic enpineering principles. (2) New construction or substantial improvements of structures shell be elevated or flood-proofed to elevation established in accordance with Article 4, Section C (11). Standard for Subdivision Proposals. (1) All subdivision proposals shall be consistent with the need to tiinimize flood damaze; (2) All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize Flood damages (3) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hnegards, and; (4) Base fiood 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 (50) lots or five (5) acres.

Statutory Authorization. The State Legislature has delegated to local governmental units the responsibility for adopting regulations designed to promote the public health, safety and general welfare of their citizenry. This chapter is enacted under such general authority. (bo) Findings of Fact. . (1) The flood hazard areas of the City 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 protec- tion and relief and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. 1986 Replacement / 21 Floodplain Regulations 1412.01 (2) These flood losses are caused by the cumulative effect of obstructions in floodplains, causing increases _in flood heights and velocities, and by occupancy, in flood hazard areas, by uses vulnerable to floods or hazardous to other lands which are inadequately elevated, floodproofed or otherwise protected from flood damage. (ec) Statement of Purpose. It is the purpose of this chapter to pro- mote 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: (1) (2) (3) (4) (5) (6) 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; s- Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; Control the alteration of natural floodplains, stream channels and natural protective barriers, which are involved in the accommodation of flood waters; Control filling, grading and mineral extraction which may increase erosion or flood damage; Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands; and ; Prohibit man-made alteration of sand dunes and mangrove stands within Zones V1-30, VE and V on the community's FIRM which would increase potential flood damage. (d) Objectives. The objectives of this chapter are to: (1) (2) (3) (4) (5) (6) (7) Protect human life and health; Minimize expenditure of public money for costly flood-control projects; Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; Minimize prolonged business interruptions; Minimize damage to public facilities and utilities, such as water and gas mains, electric, telephone and sewer lines and streets and bridges, located in floodplains; 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 future flood blight areas; Insure that potential homebuyers are notified that property is in a flood area. .

Any walled and roofed addition which is connected by a fire wall or is separated by independent perimeter load-bearing walls is new construction. . "Area of special flood hazard" means that area, of and within a community, in the floodplain, which is subject to a one percent chance of flooding annually, i.e. the 100-year flood. "Base flood" means the flood having a one percent chance of being equaled or exceeded in any given year. "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 or 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 breakway walls. "Fair market value" means the value of property or structures, as used in the definition of substantial improvement, as determined by the County Tax Assessor, either: A. Before the improvement was started; or B. If the structure has been damaged and is being restored, before the damage occurred. "Flood" or "flooding" means a general and temporary condition of partial or complete inundation of normally dry land areas from: A. The overflow of inland or tidal waters; or B. The unusual and rapid accumulation of run-off of surface waters from any source. 1987-A Replacement 23 Floodplain Regulations . 1412.02 oon, (12) (13) (14) (15) (16) (17) (18) (19) (20) (21) (22) "Flood control works" means any man-made construction, such as a dam, levee, groin or jetty, designed to alter the flood potential of the body of water on or adjacent to which it is built.
