Definitions.
As used in this section, the following terms shall have the meanings indicated:
BASE FLOODThe flood having a one-percent chance of being equaled or exceeded in any given year, also referred to as the 100-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 100-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 riverine areas.
BASEMENTAny area of the building having its floor subgrade (below ground level) on all sides.
COSTAs 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.
DEVELOPMENTAny man-made change to improved or unimproved real estate, including but not limited to the construction of buildings or structures; the construction of additions, alterations or substantial improvements to buildings or structures; the placement of buildings or structures; mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment; the storage, deposition, or extraction of materials; and the installation, repair or removal of public or private sewage disposal systems or water supply facilities.
FINISHED LIVING SPACEAs related to fully enclosed areas below the base flood elevation (BFE), a space that is, but is not limited to, heated and/or cooled, contains finished floors, has sheetrock walls that may or may not be painted or wallpapered, and other amenities, such as furniture, appliances, bathrooms, fireplaces and other items that are easily damaged by floodwaters and expensive to clean, repair or replace. Unfinished enclosed areas below the BFE should comply with FEMA Technical Bulletin 2, Flood-Damage Resistant Materials Requirements.
FLOODA 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/runoff of surface waters from any source.
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 (100-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 an examination, evaluation and determination of flood hazards and, if appropriate, corresponding water surface elevations.
FLOODWAYThe 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 one foot. For the purposes of these regulations, the term "regulatory floodway" is synonymous in meaning with the term "floodway."
HISTORIC STRUCTUREAny structure that is:
(a) 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;
(b) 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;
(c) 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
(d) Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either:
(1) By an approved state program as determined by the Secretary of the Interior,\; or
(2) Directly by the Secretary of the Interior in states without approved programs.
LOWEST FLOORThe lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access or storage, in an area other than a basement area is not considered a building's lowest floor, provided that such an area meets the design requirements specified in Subsection
5.3.1.3 of this regulation.
MARKET VALUEAs related to substantial improvement and substantial damage, the market value of the structure shall be determined by the property's tax assessment, minus land 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.
NEW CONSTRUCTIONStructures for which the start of construction commenced on or after November 16, 1981, the effective date of the floodplain management regulations, and includes any subsequent improvements to such structures.
RECREATIONAL VEHICLEA vehicle which is: (a) built on a single chassis; (b) 400 square feet or less when measured at the largest horizontal projection; (c) designed to be self-propelled or permanently towable by a light-duty truck; and (d) 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. SFHAs are determined utilizing the base flood elevations (BFE) provided on the flood profiles in the Flood Insurance Study (FIS) for a community. BFEs provided on Flood Insurance Rate Map (FIRM) are only approximate (rounded up or down) and should be verified with the BFEs published in the FIS for a specific location. SFHAs include, but are not necessarily limited to, the land shown as Zones A, A1-30, AE, AO, AH on a FIRM. The SFHA is also called the area of special flood hazard.
START OF CONSTRUCTIONThe date the building permit was issued, provided that 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.
STRUCTUREA walled and roofed building which is principally above ground, including a manufactured home, a gas or liquid storage tank, or other man-made facilities or infrastructures.
SUBSTANTIAL DAMAGEDamage 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 IMPROVEMENTAny combination of repairs, reconstruction, rehabilitation, alterations, additions or other improvements to a structure, taking place during a ten-year period, in which the cumulative cost equals or exceeds 50% of the market value of the structure before the start of construction of the improvement. This term includes structures that have incurred substantial damage, regardless of the actual repair work performed. For 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: (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."
VARIANCEA grant of relief by the Zoning Board of Appeals from the terms of this section of the regulations that allows construction in a manner otherwise prohibited and where specific enforcement would result in unnecessary hardship.
VIOLATIONFailure of a structure or other development to be fully compliant with the community's floodplain management regulation. A structure or other development without required permits, lowest floor elevation documentation, flood-proofing certificates or required floodway encroachment calculations is presumed to be in violation until such time as that documentation is provided.
WATER SURFACE ELEVATIONThe 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 riverine areas.
