increased flood heights, additional threats to public safety, extraordinary public expense,
create nuisances, cause fraud on or victimization of the public, or conflict with existing
local laws or ordinances.
(c) Any applicant to whom a variance is granted shall be given written notice that
the structure will be permitted to be built with a lowest floor elevation feet
below the base flood elevation, and that the cost of flood insurance will be commen-
surate with the increased risk resulting from the reduced lowest floor elevation.

PROVISIONS FOR FLOOD HAZARD REDUCTION
SECTION A. GENERAL STANDARDS
In all areas of special flood hazards the following provisions are required.
(1) All new construction and substantial improvements shall be anchored to prevent
flotation, collapse or lateral, movement of the structure;
(2) All new construction or substantial improvements shall be constructed by methods and
practices that minimize flood damage;
(3) All new construction or substantial improvements shall be constructed with materials
and utility equipment resistant to flood damage;
(4) All new and replacement water supply systems shall be designed to minimize or
eliminate infiltration of floodwaters into the system;
(5) New and replacement sanitary sewage systems shall be designed to minimize or elim-
inate infiltration of flood waters into the system and discharges from the systems into
flood waters; and,
(6) On site waste disposal systems shall be located to avoid impairment to them or con-
tamination from them during flooding.'
SECTION B. SPECIFIC STANDARDS
In all areas of special flood hazards where base flood elevation data has been provided as
set forth in (i) Article 3, Section B, (ii) Article 4, Section B, (7), or (iii) Article 5,
Section D, (3) the following provision s are required:
(1) Residential Construction - New construction or substantial improvement of any resid-
ential structure shall have the lowest floor, including basement, elevated to or above the
base flood elevation. A registered professional engineer, architect, or land surveyor shall
submit a certification to the Building Official that the standard of this subsection, as
proposed in Article 4, Section C(1) (a), is satisfied.
(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
attendent utility and sanitary facilities, be floodproofed so that below the base flood level
the structure is water tight with walls substantially impermeable to the passage of water
and with structural components having the capability of resisting hydrostatic and hydro-
dynamic loads and effects of buoyancy. A registered professional engineer or architect
shall submit a certification to the Building Official that the standards of this subsection as
proposed in Article 4, Section C (1) (c), are satisfied.
(3) Mobile Homes -
(a) No mobile home shall be placed in a floodway, or if applicable, a coastal
high hazard area, except in an existing mobile home park or existing mobile home sub-
division.
(b) All mobile homes shall be anchored to resist flotation, collapse, or lateral
movement. Specific requirements shall be:
(i) over-thetop ties at each of the four corners of the mobile home, with two
additional ties per side at intermediate locations and pobile homes less than 50 feet
long requiring one additional tie per side;
(ii) frame ties at each corner of the home with five additional ties per side at
intermediate points and mobile homes less than 50 feet long requiring fouradditional tie
per side;
(iii) all components of the anchoring system be capable of carrying a force of
4, 800 pounds;
(iv) any additions to the mobile home be similarly anchored.
