[Adopted 5-25-1977 by Ord. No. 19-77 (Ch. 49A, Art. I, of
the 1969 Code)]
The responsible person shall review proposed developments to
assure that all necessary permits have been received from those governmental
agencies from which approval is required by federal or state law,
including Section 404 of the Federal Water Pollution Control Act Amendments
of 1972, 33 U.S.C. § 1344.
The responsible person shall review all permit applications
to determine whether proposed building sites will be reasonably safe
from flooding. If a proposed building site is in a flood-prone area,
all new construction and substantial improvements, including the placement
of prefabricated buildings and mobile homes, shall:
A. Be designed or modified and adequately anchored to prevent flotation,
collapse or lateral movement of the structure.
B. Be constructed with materials and utility equipment resistant to
flood damage.
C. Be constructed by methods and practices that minimize flood damage.
The responsible person shall review subdivision proposals and
other proposed new developments to determine whether such proposals
will be reasonably safe from flooding if a subdivision proposal or
other proposed new development is in a flood-prone area. Any such
proposals shall be reviewed to assure that:
A. All such proposals are consistent with the need to minimize flood
damage within the flood-prone area.
B. All public utilities and facilities, such as sewer, gas, electrical
and water systems, are located and constructed to minimize or eliminate
flood damage.
C. Adequate drainage is provided to reduce exposure to flood hazards.
For the purpose of the determination of applicable flood insurance
risk premium rates within Zone A on a community's Flood Hazard
Boundary Map, the responsible person shall:
A. Obtain or require the applicant to furnish the elevation in relation
to mean sea level of the lowest habitable floor, including basement,
of all new or substantially improved structures, and whether or not
such structures contain a basement.
B. Obtain or require the applicant to furnish, if the structure has
been floodproofed, the elevation in relation to mean sea level to
which the structure was floodproofed.
C. Maintain a record of all such information.
The responsible person shall require that all mobile homes to
be placed within Zone A on the community's Flood Hazard Boundary
Map 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:
A. Over-the-top ties be provided at each of the four corners of the
mobile home, with two additional ties per side at intermediate locations,
and mobile homes less than 50 feet long shall require one additional
tie per side.
B. Frame ties be provided at each corner of the home, with five additional
ties per side at intermediate points, and mobile homes less than 50
feet long requiring four additional ties per side.
C. All components of the anchoring system be capable of carrying a force
of 4,800 pounds.
D. Any additions to the mobile home be similarly anchored.
The current Flood Hazard Boundary Map issued by the Federal
Insurance Administration for this community, and any officially published
revisions to this map, are adopted as the official map for the enforcement
of this article. Zone A on this map delineates the area within which
the requirements of this article will be enforced.
Unless specifically defined below, words or phrases used in
this document shall be interpreted so as to give them the same meanings
as they have in common usage and so as to give this document its most
reasonable application.
BASE FLOOD
The flood having a one-percent chance of being equaled or
exceeded in any given year.
DEVELOPMENT
Any man-made change to improved or unimproved real estate,
including but not limited to buildings or other structures, mining,
dredging, filling, grading, paving, excavation or drilling operations.
FLOOD
A general and temporary condition of partial or complete
inundation of normally dry land areas from the overflow of inland
or tidal waters or the unusual and rapid accumulation or runoff of
surface waters from any source.
FLOODPROOFING
Any combination of structural and nonstructural additions,
changes or adjustments to structures which reduce or eliminate flood
damage to real estate or improved real property, water and sanitary
facilities, structures and their contents.
HABITABLE FLOOR
Any floor usable for living purposes, which include working,
sleeping, eating, cooking or recreation or a combination thereof.
A floor used only for storage purposes is not a habitable floor.
MOBILE HOME
A structure, transportable in one or more sections, which
is built on a permanent chassis and is designed to be used with or
without a permanent foundation when connected to the required utilities.
It does not include recreational vehicles or travel trailers. The
term includes but it is not limited to the definition of "mobile home"
as set forth in regulations governing the Mobile Home Safety and Construction
Standards Program [24 CFR 3282.7(a)].
PERSON
Includes any individual or group of individuals, corporation,
partnership, association or any other entity, including state and
local governments and agencies.
RIVERINE
Relating to, formed by or resembling a river (including tributaries),
stream, brook, etc.
STRUCTURE
For floodplain management purposes, a walled and roofed building
that is principally above ground, including a gas or liquid storage
tank, as well as a mobile home.
SUBSTANTIAL IMPROVEMENT
Any repair, reconstruction or improvement of a structure,
the cost of which equals or exceeds 50% of the market value of the
structure either before the improvement or repair is started or, if
the structure has been damaged and is being restored, before the damage
occurred. For the purposes of this definition, substantial improvement
is considered to occur when the first alteration of any wall, ceiling,
floor or other structural part of the building commences, whether
or not that alteration affects the external dimensions of the structure.
The term does not, however, include either any project for improvement
of a structure to comply with existing state or local health, sanitary
or safety code specifications which are solely necessary to assure
safe living conditions or any alteration of a structure listed on
the National Register of Historic Places or a state inventory of historic
places.
VARIANCE
A grant of relief by a community from the terms of a floodplain
management regulation.
