During temporary absence or disability of the mayor, the governing body of the city shall designate an acting enforcement official.
(Ord. 260, Sec. 2)
The governing body of the city hereby designates the current flood hazard boundary map/flood insurance rate map, and amendments, as the official map to be used in determining those areas of special flood hazard.
(Ord. 260, Sec. 3)
No person shall erect, construct, enlarge or improve any building or structure in the city or cause the same to be down without first obtaining a separate development permit for each building or structure.
(a) Within Zone(s) A on the official map, separate development permits are required for all new construction, substantial improvements and other developments, including the placement of mobile homes.
(b) Application. To obtain a permit, the applicant shall first file an application therefor in writing on a form furnished for that purpose. Every such application shall:
(1) Identify and describe the work to be covered by the permit for which application is made.
(2) Describe the land on which the proposed work is to be done by lot, block, tract and house and street address, or similar description that will be readily identify and definitely locate the proposed building or work.
(3) Indicate the use or occupancy for which the proposed work is intended.
(4) Be accompanied by plans and specifications for proposed construction.
(5) Be signed by the permittee or his or her authorized agent who may be required to submit evidence to indicate such authority.
(6) Within designated flood prone areas, be accompanied by elevations (in relation to mean sea level) of the lowest floor (including basement) or in the care of floodproofed nonresidential structures, the elevation to which it has been floodproofed. Documentation or certification of such elevations will be maintained by the mayor.
(7) Give such other information as reasonably may be required by the mayor.
(Ord. 260, Sec. 4)
The mayor shall review all development permit applications to determine if the site of the proposed development is reasonably safe from flooding and that all necessary permits have been received as required by federal or state law.
(Ord. 260, Sec. 5)
The mayor, in reviewing all applications for new construction, substantial improvements, prefabricated buildings, placement of mobile homes and other development(s) (as defined in section 16-102 of this article) will:
(a) Obtain, review and reasonably utilize, if available any regulatory flood elevation data from federal, state or other sources, until such other data is provided by the Federal Insurance Administration in a flood insurance study; and require within areas designated as Zone A on the official map that the following performance standards be met:
(1) Residential Construction -- New construction or substantial improvement of any residential structure shall have the lowest floor, including basement, elevated to or above the base flood elevation.
(2) Non-Residential Construction -- New construction or substantial improvement of any commercial, industrial or other non-residential structure shall either have the lowest floor, including basement, elevated to the level of the base flood elevation or, together with attendant utility and sanitary facilities, be floodproofed so that below such a level the structure 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. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certification shall be provided to the local enforcement official.
(b) Require the use of construction materials and utility equipment that are resistant to flood damage.
(c) Require the use of construction methods and practices that will minimize flood damage.

(e) Assure that in regard to mobile homes, specific anchoring requirements are:
(1) Over-the-top ties be provided at each of the four corners of the mobile home with two additional ties per side at the intermediate locations and mobile homes less than 50 feet long requiring an additional tie per side.
(2) Frame ties be provided at each corner of the home with five additional ties per side at intermediate points and mobile homes less than 50 feet long requiring four additional ties per side.
(3) All components of the anchoring system be capable of carrying a force of 4,800 pounds.
(4) Any additions to mobile homes be similarly anchored.
(Ord. 260, Sec. 6)
The governing body of the city shall review all subdivision applications and shall make findings of fact and assure that:
(a) All such proposed developments are consistent with the need to minimize flood damage.
(b) Subdivision proposals and other proposed new development greater than five acres of 50 lots, whichever is lesser, include within such proposals regulatory flood elevation data in areas designated Zone A.
(c) Adequate drainage is provided so as to reduce exposure to flood hazards.
(d) All public utilities and facilities are located so as to minimize or eliminate flood damage.
(Ord. 260, Sec. 7)
New and replacement water and sewer systems shall be constructed to eliminate or minimize infiltration by, or discharge into floodwaters. Moreover, on-site waste disposal systems will be designed to avoid impairment or contamination during flooding.
(Ord. 260, Sec. 8)
The governing body will ensure that the flood carrying capacity within the altered or relocation of any watercourse is maintained. The city will notify, in riverine situations, adjacent communities and the State Coordinating Office prior to any alteration or relocation of a watercourse and submit copies of such notification to the Federal Emergency Management Agency. Moreover, the city will work with appropriate state and federal agencies in every way possible in complying with the National Flood Insurance Program in accordance with the National Flood Disaster Protection Act of 1973.
(Ord. 260, Sec. 9)

(e) Mobile Home -- 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. It does not include recreational vehicles or travel trailers.
(f) Mobile Home park (Subdivision) -- Mobile home subdivision means a parcel (or contiguous parcels) of land which has been divided into two or more lots for rent or sale and the placement of mobile homes.
