Definitions. For the purposes of this section, the
following words shall have the meanings defined herein:
BASE FLOOD
The flood having a one-percent chance of being equaled or
exceeded in any given year, also referred to as the one-hundred-year
flood, as published by the Federal Emergency Management Agency (FEMA)
as part of a Flood Insurance Study (FIS) and depicted on a Flood Insurance
Rate Map (FIRM).
BASE FLOOD ELEVATION (BFE)
The elevation of the crest of the base flood or one-hundred-year
flood. The height in relation to mean sea level expected to be reached
by the waters of the base flood at pertinent points in the floodplains
of coastal and riverine areas.
BASEMENT
Any area of the building having its floor subgrade (below
ground level) on all sides.
BUILDING
See definition for "structure."
COST
As related to substantial improvements, the cost of any reconstruction,
rehabilitation, addition, alteration, repair or other improvement
of a structure shall be established by a detailed written contractor's
estimate. The estimate shall include, but not be limited to: the cost
of materials (interior finishing elements, structural elements, utility
and service equipment); sales tax on materials, building equipment
and fixtures, including heating and air conditioning and utility meters;
labor; built-in appliances; demolition and site preparation; repairs
made to damaged parts of the building worked on at the same time;
contractor's overhead; contractor's profit; and grand total. Items
to be excluded include: cost of plans and specifications, survey costs,
permit fees, outside improvements, such as septic systems, water supply
wells, landscaping, sidewalks, fences, yard lights, irrigation systems,
and detached structures, such as garages, sheds, and gazebos.
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
or storage of equipment or materials.
FLOOD INSURANCE RATE MAP (FIRM)
The official map of a community on which the Federal Emergency
Management Agency (FEMA) has delineated both the special flood hazard
areas one-hundred-year floodplain) and the insurance risk premium
zones applicable to a community.
FLOOD INSURANCE STUDY (FIS)
The official study of a community in which the Federal Emergency
Management Agency (FEMA) has conducted a technical engineering evaluation
and determination of local flood hazards, flood profiles and water
surface elevations. The Flood Insurance Rate Maps (FIRM), which accompany
the FIS, provide both flood insurance rate zones and base flood elevations,
and may provide the regulatory floodway limits.
FLOOD or FLOODING
A general and temporary condition of partial or complete
inundation of normally dry land areas from either the overflow of
inland or tidal waters, or the unusual and rapid accumulation or runoff
of surface waters from any source.
FLOODWAY
The channel of a river or other watercourse and the adjacent
land areas that must be reserved in order to discharge the base flood
without cumulatively increasing the water surface elevation more than
1.0 foot. For the purposes of these regulations, the term "regulatory
floodway" is synonymous in meaning with the term "floodway."
FUNCTIONALLY DEPENDENT USE OR FACILITY
A use or facility that cannot perform its intended purpose
unless it is located or carried out in close proximity to water. The
term includes only docking facilities, port facilities that are necessary
for the loading and unloading of cargo or passengers, and ship building
and ship repair facilities, but does not include long-term storage
or related manufacturing facilities.
HIGHEST ADJACENT GRADE (HAG)
The highest natural elevation of the ground surface prior
to construction next to the proposed walls of a structure.
HISTORIC STRUCTURE
Any structure that is:
(1)
Listed individually in the National Register
of Historic Places (a listing maintained by the Department of the
Interior) or preliminarily determined by the Secretary of the Interior
as meeting the requirements for individual listing on the National
Register;
(2)
Certified or preliminarily determined by the
Secretary of the Interior as contributing to the historic significance
of a registered historic district or a district preliminarily determined
by the Secretary to qualify as a registered historic district;
(3)
Individually listed on a state inventory of
historic places in states with historic preservation programs which
have been approved by the Secretary of the Interior; or
(4)
Individually listed on a local inventory of
historic places in communities with historic preservation programs
that have been certified either:
(a)
By an approved state program as determined by
the Secretary of the Interior; or
(b)
Directly by the Secretary of the Interior in
states without approved programs.
LOWEST FLOOR
The lowest floor of the lowest enclosed area (including basement).
An unfinished or flood-resistant enclosure usable solely for the parking
of vehicles, building access or storage in an area other than a basement
area is not considered a building's lowest floor.
MANUFACTURED HOME
A structure, transportable in one or more sections, which
is built on a permanent chassis and is designed for use with a permanent
foundation when attached to the required utilities.
MARKET VALUE
The market value of the structure shall be determined by
using a computer assisted mass appraisal incorporating the three approaches
to value prior to the start of the initial repair or improvement,
or in the case of damage, the value of the structure prior to the
damage occurring.
MEAN SEA LEVEL (MSL)
The North American Vertical Datum (NAVD) of 1988 or other
datum, to which base flood elevations shown on a community's Flood
Insurance Rate Map (FIRM) are referenced. The NAVD is approximately
equal to the National Geodetic Datum of 1929 minus 0.8 feet. The NAVD
is also approximately equal to the Hartford Metropolitan District
Commission Datum minus 2.9 feet.
NEW CONSTRUCTION
Structures for which the start of construction commenced
on or after October 28, 1969, and includes any subsequent improvements
to such structures.
RECREATIONAL VEHICLE
A vehicle which is:
(1)
Built on a single chassis;
(2)
Four hundred square feet or less when measured
at the largest horizontal projection;
(3)
Designed to be self-propelled or permanently
towable by a light-duty truck; and
(4)
Designed primarily not for use as a permanent
dwelling but as a temporary living quarters for recreational, camping,
travel, or seasonal use.
SPECIAL FLOOD HAZARD AREA (SFHA)
The land in the floodplain within a community subject to
a one-percent or greater chance of flooding in any given year. For
purposes of this section, the term "special flood hazard area" is
synonymous in meaning with the phrase "area of special flood hazard."
START OF CONSTRUCTION
For other than new construction or substantial improvements
under the Coastal Barrier Resources Act (P.L. 97-348), includes substantial
improvement and means the date the building permit was issued, provided
the actual start of construction, repair, reconstruction, rehabilitation,
addition placement, substantial improvement or other improvement was
within 180 days of the permit date. The "actual start" means either
the first placement of permanent construction of a structure on a
site, such as the pouring of slab or footings, the installation of
piles, the construction of columns, or any work beyond the stage of
excavation, or the placement of a manufactured home on a foundation.
Permanent construction does not include land preparation, such as
clearing, grading and filling; nor does it include the installation
of streets and/or walkways; nor does it include excavation for a basement,
footings, piers, or foundations or the erections of temporary forms;
nor does it include the installation on the property of accessory
buildings, such as garages or sheds not occupied as dwelling units
or not part of the main structure. For a substantial improvement,
the "actual start of construction" means the first alteration of any
wall, ceiling, floor, or other structural part of a building, whether
or not that alteration affects the external dimensions of the building.
STRUCTURE
A walled and roofed building, including a gas or liquid storage
tank, that is principally above ground, as well as a manufactured
home. A structure includes any attached additions, garages, decks,
sunrooms, or any other structure attached to the main structure.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure, whereby the
cost of restoring the structure to its predamaged condition would
equal or exceed 50% of the market value of the structure before the
damage occurred.
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition or other improvement
of a structure, the cost of which equals or exceeds 50% of the market
value of the structure before the start of construction of the improvement.
This term includes structures which have incurred substantial damage,
regardless of the actual repair work performed. The term does not,
however, include either:
(1)
Any project for improvement of a structure to
correct existing violations of state or local health, sanitary, or
safety code specifications which have been identified by the local
code enforcement official and which are the minimum necessary to assure
safe living conditions; or
(2)
Any alteration of an historic structure, provided
that the alteration will not preclude the structure's continued designation
as an historic structure.
VIOLATION
Failure of a structure or other development to be fully compliant
with the community's floodplain management ordinance. A structure
or other development without required permits, lowest floor elevation
documentation, floodproofing certificates or required floodway encroachment
calculations is presumed to be in violation until such time as that
documentation is provided.
WATER SURFACE ELEVATION
The height, in relation to the North American Vertical Datum
(NAVD) of 1988 (or other datum, where specified), of floods of various
magnitudes and frequencies in the floodplains of coastal or riverine
areas. The NAVD is approximately equal to the National Geodetic Datum
of 1929 minus 0.8 feet. The NAVD is also approximately equal to the
Hartford Metropolitan District Commission Datum minus 2.9 feet.
