§ 42-50. General standards.

In all areas of special flood hazard, all development sites including new construction and substantial improvements shall be reasonably safe from flooding, and meet the following provisions:

(a)

New construction and substantial improvements shall be designed or modified and adequately anchored to prevent flotation, collapse, and lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;

(b)

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 of Florida 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 and substantial improvements shall be constructed by methods and practices that minimize flood damage;

(e)

Electrical, heating, ventilation, plumbing, air conditioning equipment and other service facilities, including duct work, 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 systems;

(g)

New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters;

(h)

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

(i)

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

(j)

Any alteration, repair, reconstruction or improvements to a building that is not in compliance with the provisions of this article, shall be undertaken only if such nonconformity is not furthered, extended or replaced;

(k)

All applicable additional federal, state and local permits shall be obtained and submitted to the floodplain administrator together with the application for development permit. Copies of such permits shall be maintained on file with the development permit. State permits may include, but not be limited to, the following:

(1)

South Florida Water Management District: pursuant to F.S. § 373.036(2)(a);

(2)

Department of Community Affairs: pursuant to F.S. § 380.05 and F.S. pt. IV, ch. 553;

(3)

Department of health: pursuant to F.S. § 381.0065; and

(l)

Standards for subdivision proposals and other new proposed development (including manufactured homes):

(1)

Such proposals shall be consistent with the need to minimize flood damage;

(2)

Such proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize or eliminate flood damage; and

(3)

Such proposals shall have adequate drainage provided to reduce exposure to flood hazards.

(m)

When proposed new construction and substantial improvements are located in multiple flood hazard risk zones or in a flood hazard risk zone with multiple base flood elevations, the entire structure shall meet the standards for the most hazardous flood risk zone and the highest base flood elevation.

(n)

Any reconstruction, rehabilitation, or other improvements to a PRE-FIRM structure that is not in compliance with the provisions of this article, shall be undertaken only if the lowest floor of such noncompliance is at or above the existing lowest floor elevation, and does not constitute substantial improvement.

(o)

All improvements, modifications, and/or additions to all existing structures shall be calculated cumulatively for five years from the date of the initial permit date. Additionally, all reconstruction and/or repairs to a damaged structure shall be calculated cumulatively for five years from the date of the initial permit date.
