§ 35-F142. Specific Standards.

In all areas of special flood hazards where base flood elevation data has been provided in accordance with this ordinance, the following provisions are required:

(a)

Residential Construction.

(1)

Construction of habitable structures within the regulatory floodplain (base flood) is not allowed. New construction and substantial improvement of any residential structure shall have the lowest floor (including basement) elevated one (1) foot above the regulatory floodplain with the lowest adjacent grade at or above the regulatory floodplain. A registered professional engineer, architect, or land surveyor shall submit a certification to the floodplain administrator that the standard of this ordinance (reference subsection 35-F132(b)), is satisfied.

(b)

Nonresidential Construction.

(1)

New construction or substantial improvements of any commercial, industrial or other nonresidential structure shall have either (a) the lowest floor, including basement, elevated to one (1) foot above the regulatory floodplain, or (b) have the lowest floor, including basement, with attendant utility and sanitary facilities, be floodproofed so that below the regulatory floodplain level plus one (1) foot above the lowest floor, 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 the effects of buoyancy.

(2)

New construction and substantial improvements, with fully enclosed areas below the lowest floor that are usable solely for parking of vehicles, building access or storage in an area other than a basement 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 s. Designs for meeting this requirement must either be certified by a registered professional engineer or meet or exceed the following minimum criteria:

A minimum of two (2) openings on separate walls having a total net area of not less than one (1) square inch for every square foot of enclosed area subject to flooding shall be provided.

(3)

Electrical heating, ventilation, plumbing and 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.

(4)

A registered professional engineer shall submit a certification to the floodplain administrator that the standards of this subsection are satisfied. The certification shall include a statement to the effect that the engineer has developed and/or reviewed structural design, specifications, and plans for the construction and finds them to be in accordance with this subsection. A record of such certification which includes the specific elevation (in relation to mean sea level) to which such structures are floodproofed shall be maintained by the floodplain administrator. The director of public works shall utilize the floodproofing regulations manual prepared by the United States Army Corps of Engineers as a guide in determining construction requirements.

(c)

Manufactured Homes.

(1)

Construction/installation of manufactured homes within the regulatory floodplain (base flood) is not allowed.

(d)

Floodways. Located within the areas of special flood hazard are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris, potential projectiles and erosion potential, the following provisions shall apply:

(1)

Encroachments are prohibited, including fill, new construction, substantial improvements and other developments within the adopted regulatory floodway, unless certification by a registered professional engineer is provided demonstrating that encroachments shall not result in any increase in flood levels during occurrence of the regulatory discharge.

(2)

If subsection (1) above is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this ordinance.

(3)

The placement of any manufactured home is prohibited except in an existing manufactured home park or subdivision.

(e)

Recreational Vehicles. Require that recreational vehicles placed on sites within Zones A1-30, AH, and AE on the community's FIRM either (i) be on the site for fewer than one hundred eighty (180) consecutive days, or (ii) be fully licensed and ready for highway use, or (iii) meet the permit requirements of Article 4, Section C(1), and the elevation and anchoring requirements for "manufactured homes" in paragraph (4) of this section. A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities and security devices, and has no permanently attached additions.
