A.
The areas of the Village which are subject to periodic flooding as
described by the Flood Hazard Boundary Map issued by the Federal Emergency
Management Agency and as delineated on the Zoning Map are designated
as a Flood Hazard Overlay District for the purposes of protecting
human life, preventing material losses and reducing the cost to the
public of rescue and relief efforts necessitated by the unwise occupancy
of areas subject to floods.
[Amended 10-27-1997 by L.L. No. 6-1997]
B.
In order to accomplish its purposes, this chapter uses the following
methods with regard to the flood hazard area:
(1)
Restrict or prohibit uses which are dangerous to health, safety and
property due to water or erosion or in flood height or velocities.
(2)
Require that uses vulnerable to floods, including facilities which
serve such uses, be protected against flood damage at the time of
initial construction.
(3)
Control the alteration of natural floodplains, stream channels and
natural protective barriers, which are involved in the accommodation
of floodwaters.
(4)
Control filling, grading, dredging and other development which may
increase flood damage.
(5)
Prevent or regulate the construction of flood barriers which will
unnaturally divert floodwaters or which may increase hazards to other
lands.
A.
Within the Flood Overlay, no person shall erect, construct, enlarge,
alter, repair, improve or move any permitted building or structure,
nor shall any permitted activity such as mining, dredging, filling,
grading, paving, excavation or drilling commence without first obtaining
a certificate of compliance from the Building Inspector.
B.
The Building Inspector shall review all applications for a certificate
of compliance for activities within the flood hazard area and shall
not issue a permit unless the following requirements are met:
(1)
Construction or substantial improvement. New construction or substantial
improvement of any structure shall either have the lowest floor, including
basement, elevated to the level of the base flood elevation or, together
with attendant utility and sanitary facilities, be floodproofed so
that below the base flood level 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 effects of buoyancy. A registered professional engineer
or architect shall certify that the standards of this subsection are
satisfied.
(2)
Anchoring.
(a)
All new construction and substantial improvements shall be anchored
to prevent flotation, collapse or lateral movement of the structure.
(b)
All temporary mobile homes shall be anchored to resist flotation,
collapse or lateral movement by providing over-the-top and frame ties
to ground anchors. Specific requirements shall be that:
[1]
Over-the-top ties be provided at each end of the mobile home
with two additional ties per side at intermediate locations and mobile
homes less than 50 feet long requiring one additional tie per side;
[2]
Frame ties be provided at each corner of the home with five
additional ties per side at intermediate points and mobile home less
than 50 feet long requiring four additional ties per side;
[3]
All components of the anchoring system be capable of carrying
a force of 4,800 pounds; and
[4]
Any additions to the mobile home shall be similarly anchored.
(3)
Construction materials and methods.
(4)
Utilities.
(a)
All new and replacement water supply systems shall be designed
to minimize or eliminate infiltration of floodwaters into the system.
(b)
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 the floodwaters.
(c)
On-site waste disposal systems shall be located to avoid impairment
to them or contamination from them during flooding.
