elevation and shall extend at such height for a distance of at least
15 feet beyond the limits of any structure erected thereon.
2.
Structures on fill shall be built so that the basement or, in the
event there is no basement, the lowest floor level, is at a minimum
of one foot above the flood hazard design elevation.
3.
Structures not placed on fill shall be otherwise elevated so that
the first floor is at a minimum of one foot above the flood hazard
design elevation or shall be floodproofed as set forth in paragraph
4 below. Floodproofing alone shall not be adequate for residences,
hospitals, nursing homes, schools, day-care centers, food and drinking
establishments, places of public accommodations and similar uses.
4.
Floodproofing measures shall be consistent with the flood protection
elevation for the particular area, flood velocities, durations, rates
of rise, hydrostatic and hydrodynamic forces and other similar factors.
The Unified Planning Board shall require the applicant to submit a
plan or document certified by a registered professional engineer that
the floodproofing measures are consistent with the flood hazard design
elevation and associated flood factors. Any or all of the following
proven measures may be required:
(a)
Anchorage to resist flotation and lateral movement.
(b)
Installation of watertight doors, bulkheads, and shutters or
similar devices.
(c)
Reinforced walls to resist water pressures.
(d)
Use of paints, membranes or mortars to reduce seepage of water
through walls.
(e)

which will permit the drains to be closed to prevent backup of sewerage
or stormwaters into the structure. Gravity drainage of basements may
be eliminated by mechanical devices.
(k)
Location of all electrical equipment, circuits and installed
electrical appliances in a manner which will assure they are not subject
to inundation and flooding.
(l)
Storage facilities for chemicals, explosives, buoyant materials,
flammable liquids or other toxic or hazardous materials shall be situated
above the flood hazard design elevation and shall be floodproofed
to prevent flotation of storage containers or damage to storage containers
which could result in the escape of toxic materials into the floodwaters.
(m)
Use of construction materials which are resistant to water damage.
[Ord. No. 98-21 § 304-98]
No person shall hereafter engage in, cause or permit other persons
to engage in prohibited uses within a delineated floodplain. The following
uses shall be prohibited:

floods, to an extent of 50% or more of its replacement cost at time
of destruction, it shall not be reconstructed, except in conformity
with the provisions of this chapter.
(b)
No preexisting structure shall be moved, expanded or enlarged
unless the provisions of this chapter are complied with. This provision
does not apply to routine maintenance and repair, provided that such
maintenance and repair does not increase the flood damage potential
of the structure.
2.
In any portion of the floodplain, an existing nonconforming use or
structure may be altered or expanded, provided that such alteration
or expansion does not increase its ground coverage or flood damage
potential.
b.
If actual construction of a structure is underway on or before the
effective date of this chapter, then such construction may be completed.
Actual construction is hereby defined to include the placing of construction
materials in permanent position and fastened in a permanent manner.
The provisions of paragraph a above shall apply to such structures
upon completion of construction.
c.
Structures in the folkway abandoned for six consecutive months or
longer and structures abandoned for 12 consecutive months or longer
in the flood-fringe area after the effective date of this chapter
