In case of conflict between Chapter 275 and the Uniform Code, the more restrictive provisions shall take precedence. In addition, the following terms shall be applicable to the provisions, enforcement and administration of Article X, Excavation, Grading and Filling, and Article XI, Flood Damage Protection, only, but shall not supersede any definition stated elsewhere in this Code.
B. 
As used in this chapter, the following words shall have the meanings indicated:
APPEAL
A request for a review of the Building Inspector's interpretation of any provision of Article XI of this chapter or a request for a variance from the requirements of said Article XI.
AREA OF SHALLOW FLOODING
A designated AO or VO Zone on the Flood Insurance Rate Map (FIRM) of the Village of Roslyn Harbor with base flood depths from one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate and where velocity flow may be evident.
AREA OF SPECIAL FLOOD HAZARD
The land in the floodplain within a community subject to a one-percent or greater chance of flooding in any given year.
BASE FLOOD
The flood having a one-percent chance of being equaled or exceeded in any given year.
BASEMENT
The portion of a building having its floor subgrade (below ground level) on all sides.
BREAKAWAY WALL
A wall that is not part of the structural support of the building and is intended, through its design and construction, to collapse under specific lateral loading forces without causing damage to the elevated portion of the building or the supporting foundation system.
BUILDING
Any structure built for support, shelter or enclosure for occupancy or storage.
CELLAR
The same meaning as "basement."
COASTAL HIGH-HAZARD AREA
The area subject to high-velocity waters, including but not limited to hurricane wave wash. The area is designated on a FIRM as Zone VI - V30, VE or V.
DEVELOPMENT
Any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, dredging, filling, grading, paving, excavation or drilling operations located within the area of special flood hazard.
ELEVATED BUILDING
A nonbasement building built to have the lowest floor elevated above the ground level by means of fill, solid foundation perimeter walls, piling, columns (posts and piers) or shear walls.
FLOOD BOUNDARY AND FLOODWAY MAP (FBFM)
An official map of the community published by the Federal Emergency Management Agency as part of a riverine community's Flood Insurance Study. The FBFM delineates a regulatory floodway along watercourses studied in detail in the Flood Insurance Study.
FLOOD HAZARD BOUNDARY MAP (FHBM)
An official map of a community issued by the Federal Emergency Management Agency where the boundaries of the areas of special flood hazard have been defined but no water surface elevation is provided.
FLOOD INSURANCE RATE MAP (FIRM)
The official map on which the Federal Emergency Management Agency has delineated both the areas of special flood hazard and the risk premium zones applicable to the community.
FLOOD INSURANCE STUDY
The official report provided by and which contains the Federal Emergency Management Agency flood profiles, as well as the Flood Boundary and Floodway Map and the water surface elevation of the base flood.
FLOOD or FLOODING
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 properties and structures which reduce or eliminate flood damage to lands, water and sanitary facilities, structures and contents of buildings.
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 a designated height as determined by the Federal Emergency Management Agency in a Flood Insurance Study.
FLOOR
The top surface of an enclosed area in a building, including basement, i.e., the top of the slab in concrete slab construction or the top of wood flooring in wood frame construction.
FUNCTIONALLY DEPENDENT USE
A use which cannot perform its intended purpose unless it is located or carried out in close proximity to water, such as a docking or port facility necessary for the loading and unloading of cargo or passengers, shipbuilding and ship repair. The term does not include long-term storage, manufacture, sales or service facilities.
HABITABLE FLOOR
Any floor usable for living purposes, which includes working, sleeping, eating, cooking or recreation, or a combination thereof. A floor used only for storage purposes is not a habitable floor.
HIGHEST ADJACENT GRADE
The highest natural elevation of the ground surface, prior to construction, next to the proposed walls of a structure.
LOWEST FLOOR
The lowest level, including basement or cellar, of the lowest enclosed area. An unfinished or flood-resistant enclosure, usable solely for the parking of vehicles, building access or storage, in an area other than a basement, is not considered a building's lowest floor, provided that such an enclosure is not built so as to render the structure in violation of the applicable nonelevation design requirements of this chapter.
MANUFACTURED HOME
A structure, transportable in one or more sections, which is built on a permanent chassis and designed to be used with or without a permanent foundation when connected to the required utilities. The term also includes park trailers, travel trailers and similar transportable structures placed on a site for 180 consecutive days or longer and intended to be improved property.
MEAN SEA LEVEL
For purposes of the National Flood Insurance Program, the National Geodetic Vertical Datum (NGVD) of 1929 or other datum to which base flood elevations shown on a community's Flood Insurance Rate Map are referenced.
MOBILE HOME
The same meaning as "manufactured home."
MUDSLIDE
A general and temporary movement down a slope of a mass of rock or soil, artificial fill or a combination of these materials, caused or precipitated by the accumulation of water on or under the ground.
MUDSLIDE AREA
An area characterized by unstable slopes and land surfaces, whose history, geology, soil and bedrock structure and climate indicate a potential for mudslides.
NATIONAL GEODETIC VERTICAL DATUM (NGVD)
As corrected in 1929, a vertical control used as a reference for establishing varying elevations within the floodplain.
NEW CONSTRUCTION
Structures for which the start of construction commenced on or after the effective date of Local Law No. 2-1983, adopted December 6, 1983, incorporated as Article XI herein.
ONE-HUNDRED-YEAR FLOOD
The same meaning as "base flood."
PRINCIPALLY ABOVE GROUND
A structure which has at least 51% of the actual cash value of the structure, excluding land value, above ground.
REGULATORY FLOODWAY
The same meaning as "floodway."
SAND DUNES
Naturally occurring accumulations of sand in ridges or mounds landward of the beach.
START OF CONSTRUCTION
The initiation, excluding planning and design, of any phase of a project involving the physical alteration of the property, including land preparation, such as clearing, grading and filling; installation of streets and/or walkways; excavation for a basement, footings, piers or foundations; or the erection of temporary forms. It shall also include the placement and/or installation on the property of accessory buildings (garages or sheds), storage trailers and building materials. For manufactured homes, the "actual start" means affixing the manufactured home to its permanent site.
STRUCTURE

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.

The term does not, however, include:
(1) 
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.
(2)
