§ 4-5-4-4 APPEALS.
   The City Council shall hear and decide appeals when it is alleged there is an error in any requirement, decision or determination made by the Floodplain Administrator in the enforcement or administration of this chapter.
(Ord. 445, passed 8-1-1995)
§ 4-5-5 PROVISIONS FOR FLOOD HAZARD REDUCTION.
§ 4-5-5-1 STANDARDS OF CONSTRUCTION.
   In all areas of special flood hazards the following standards are required.
   (A)   Anchoring. All new construction and substantial improvements shall be adequately anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
   (B)   Construction materials and methods. All new construction and substantial improvement shall be constructed:
      1.   With materials and utility equipment resistant to flood damage;
      2.   Using methods and practices that minimize flood damage; and
      3.   With electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
   (C)   Elevation and floodproofing. (See § 4-5-2, Definitions, of this chapter for “new construction”, “substantial damage” and “substantial improvement”.)
      1.   (a)   Residential construction, new or substantial improvement, shall have the lowest floor, including basement:
            (1)   In an A zone, elevated one foot above the base flood elevation; and
            (2)   In all other zones, elevated to the base flood elevation.
         (b)   Upon the completion of the structure, the elevation of the lowest floor including basement shall be certified by a registered professional engineer or surveyor, or verified by the community building inspector to be properly elevated. Such certification or verification shall be provided to the Floodplain Administrator.
      2.   Nonresidential construction shall either be elevated to conform with § 4-5-5-1(C)1. of this chapter or together with attendant utility and sanitary facilities:
         (a)   Be floodproofed below the elevation recommended under § 4-5-5-1(C)1. of this chapter so that the structure is watertight with walls substantially impermeable to the passage of water;
         (b)   Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy; and
         (c)   Be certified by a registered professional engineer or architect that the standards of this subsection (C) are satisfied. Such certification shall be provided to the Floodplain Administrator.
      3.   All new construction and substantial improvement with fully enclosed areas below the lowest floor (excluding basements) that are usable solely for parking of vehicles, building access or storage, and which are subject to flooding, shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwater. Designs for meeting this requirement must exceed the following minimum criteria:
         (a)   Be certified by a registered professional engineer or architect;
         (b)   Be certified to comply with a local floodproofing standard approved by the Federal Insurance Administration, Federal Emergency Management Agency; or
         (c)   Have 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. The bottom of all openings shall be no higher than one foot above grade. Openings may be equipped with screens, louvers, valves or other coverings or devices provided that they permit the automatic entry and exit of floodwater.
(Ord. 445, passed 8-1-1995)
§ 4-5-5-2 STANDARDS FOR UTILITIES.
   (A)   All new and replacement water supply and sanitary sewage systems shall be designed to minimize or eliminate:
      1.   Infiltration of floodwaters into the systems; and
      2.   Discharge from the systems into floodwaters.
   (B)   On site waste disposal systems shall be located to avoid impairment to them, or contamination from them, during flooding.
(Ord. 445, passed 8-1-1995)
§ 4-5-5-3 STANDARDS FOR SUBDIVISIONS.
   (A)   All preliminary subdivision proposals shall identify the flood hazard area and the elevation of the base flood.
   (B)   All subdivision plans will provide the elevation of proposed structures and pad(s). If the site is filled above the base flood elevation, the final first floor and pad elevations shall be certified by a registered professional engineer or surveyor and provided to the Floodplain Administrator.
   (C)   All subdivision proposals shall be consistent with the need to minimize flood damage.
   (D)   All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize flood damage.
   (E)   All subdivisions shall provide adequate drainage to reduce exposure to flood hazards.
