§ 11-22. General standards.  


Latest version.
  • In all areas of special flood hazard the following provisions are required:

    (1)

    New construction and substantial improvements shall be anchored to prevent flotation, collapse and lateral movement of the structure;

    (2)

    Manufactured homes shall be anchored to prevent flotation, collapse, and lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This standard shall be in addition to and consistent with applicable state requirements for resisting wind forces;

    (3)

    New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage;

    (4)

    New construction or substantial improvements shall be constructed by methods and practices that minimize flood damage;

    (5)

    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, such facilities shall be located a minimum of two (2) feet above the base flood elevation;

    (6)

    New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system;

    (7)

    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;

    (8)

    On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding;

    (9)

    Any alteration, repair, reconstruction or improvements to a building that is in compliance with the provisions of this chapter shall meet the requirements of "new construction" as contained in this chapter; and

    (10)

    Any alteration, repair, reconstruction or improvements to a building that is not in compliance with the provisions of this chapter, shall be undertaken only if said non-conformity is not furthered, extended, or replaced.

    (11)

    All gas and liquid storage tanks that are principally above ground shall be anchored to prevent flotation and lateral movement.

    (12)

    When new construction and substantial improvements are located in multiple flood zones or in a flood zone with multiple base flood elevations, they shall meet the requirement for the more stringent flood zone and the highest base flood elevation.

    (13)

    New construction and substantial improvement of any building shall have the lowest floor (including basement) at least one foot above the centerline of the designated street, unless the topography of the property does not allow for strict adherence as determined by the floodplain administrator.

    (14)

    New construction and substantial improvements built on fill shall be constructed on the properly designed and compacted fill that extends beyond the building walls before dropping below the base flood elevation, and shall have appropriate protection from erosion and scour.
