Current through all regulations passed and filed through July 1, 2024
For purposes of rules 1501:22-1-01 to  1501:22-1-08 of  the Administrative Code:
(A) "Appurtenant
			 structure" means a structure which is on the same parcel of property as the
			 principal structure and the use of which is incidental to the use of the
			 principal structure.
(B) "Appeal"
			 means a request for a review of the county or municipal corporation permit
			 administrator's interpretation of any provision of the flood damage prevention
			 regulations or a request for a variance.
(C) "Area of shallow flooding" means a
			 designated AO, AH, or VO zone on a county's or municipal corporation's Flood
			 Insurance Rate Map (FIRM) with a one per cent or greater annual chance of
			 flooding to an average depth of one to three feet where a clearly defined
			 channel does not exist, where the path of flooding is unpredictable and where
			 velocity flow may be evident. Such flooding is characterized by ponding or
			 sheet flow.
(D) "Area of special
			 flood hazard" is the land in the floodplain within a county or municipal
			 corporation subject to a one per cent or greater chance of flooding in any
			 given year. The area may be designated as Zone A on the Flood Hazard Boundary
			 Map (FHBM). After detailed rate making has been completed in preparation for
			 publication of the FIRM, Zone A usually is refined into Zones A, AO, AH, A1-30,
			 AE, A99, VO, V1-30, VE, or V.
(E)
			 "Base flood" means the flood having a one per cent chance of being equalled or
			 exceeded in any given year. The base flood is also referred to as the
			 one-hundred year flood.
(F)
			 "Basement" means any area of the building having its floor subgrade (below
			 ground level) on all sides.
(G)
			 "Breakaway wall" means 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 supporting foundation system.
(H) "Coastal area" means the waters of lake
			 Erie, the islands in the lake, and the lands under and adjacent to the lake,
			 including transitional areas, wetlands, and beaches. The coastal area extends
			 in lake Erie to the international boundary line between the United States and
			 Canada and landward only to the extent necessary to include shore-lands, the
			 uses of which have a direct and significant impact on coastal waters as
			 determined by the director of natural resources.
(I) "Coastal flood hazard area" means any
			 territory within the coastal area that has been identified as a special flood
			 hazard area under the Flood Disaster Protection Act of 1973, 87 Stat. 975,
			  42 U.S.C. 4002, as amended, and is subject to
			 lake Erie-related flooding.
(J)
			 "Coastal high hazard area" means an area of special flood hazard, as identified
			 by the federal emergency management agency, along the open coast at lake Erie
			 and any other area subject to high velocity wave action from storms or seismic
			 sources along lake Erie and its bays.
(K) "Development" means any artificial change
			 to improved or unimproved real estate, including, without limitation, the
			 construction of buildings and other structures and mining, dredging, filling,
			 grading, paving, excavation and drilling operations.
(L) "Director" means the director of the
			 department of natural resources, state of Ohio or his designee.
(M) "Elevated building" means a non-basement
			 building (a) built, in the case of a building in Zones A1-30, AE, A, A99, AO,
			 AH, B, C, X, or D, to have the top of the elevated floor, or in the case of
			 building in Zones V1-30, VE, or V, to have the bottom of the lowest horizontal
			 structure member of the elevated floor, elevated above the ground level by
			 means of pilings, columns (posts and piers), or shear walls parallel to the
			 flow of the water and (b) adequately anchored so as not to impair the
			 structural integrity of the building during a flood of up to the magnitude of
			 the base flood. In the case of Zones A1-30, AE, A, A99, AO, AH, B, C, X, or D,
			 "elevated building" also includes a building elevated by means of fill or solid
			 foundation perimeter walls with openings sufficient to facilitate the unimpeded
			 movement of flood waters. In the case of Zones V1-30, VE, or V, "elevated
			 building" also includes a building otherwise meeting the definition of
			 "elevated building," even though the lower area is enclosed by means of
			 breakaway walls if the breakaway walls meet the standards of paragraph (D)(4)
			 of rule 1501:22-1-04 of  the Administrative Code.
(N) "Existing
			 manufactured home park or subdivision" means a manufactured home park or
			 subdivision for which the construction of facilities for servicing the lots on
			 which the manufactured homes are to be affixed (including, at a minimum, the
			 installation of utilities, the construction of streets, and either final site
			 grading or the pouring of concrete pads) is completed before the effective date
			 of the floodplain management regulations adopted by a county or municipality.
(O) "Expansion to an existing
			 manufactured home park or subdivision" means the preparation of additional
			 sites by the construction of facilities for servicing the lots on which the
			 manufactured homes are to be affixed (including the installation of utilities,
			 the construction of streets, and either final site grading or the pouring of
			 concrete pads).
(P) "Federal
			 Emergency Management Agency" (FEMA) means the federal agency with the overall
			 responsibility for administering the national flood insurance program.
(Q) "Flood Hazard Boundary Map"
			 (FHBM) means an official map of a county or municipal corporation, issued by
			 the federal emergency management agency, where the boundaries of the flood
			 areas having special hazards have been designated as Zone A.
(R) "Flood Insurance Rate Map" (FIRM) means
			 an official map of a community, on which the federal emergency management
			 agency has delineated both the special hazard areas and the risk premium zones
			 applicable to the community.
(S)
			 "Flood insurance rate zones" means the various flood insurance risk premium
			 zones identified on a county's or municipal corporation's FIRM or FHBM issued
			 by the federal emergency management agency. The symbols used to designate these
			 zones are as follows:
A Area of special flood hazard without base flood elevations
				determined.
A1-30, AE Area of special flood hazard with base flood
				elevations determined.
AO Area of special flood hazard having shallow water depths
				and/or unpredictable flow paths between one and three feet.
A99 Area of special flood hazard where enough progress has been
				made on a protective system, such as dikes, dams, and levees, to consider it
				complete for insurance rating purposes.
AH Area of special flood hazard having shallow water depths
				and/or unpredictable flow paths between one and three feet, and with base flood
				elevations determined.
V Area of special flood hazard along coast with velocity hazard
				(coastal high hazard area); no base flood elevations determined.
V1-30, VE Area of special flood hazard along coast with
				velocity hazard (coastal high hazard area); base flood elevations determined.
VO Area of special flood hazard along coast with velocity
				hazard having shallow water depths and/or unpredictable flow paths between one
				and three feet.
B, X Area of moderate flood hazard.
C, X Area of minimal hazard.
D Area of undetermined but possible flood hazard.
(T) "Flood insurance study" means

			 an examination, evaluation, and determination of flood hazards and, if
			 appropriate, corresponding water surface elevations and floodway boundaries.
(U) "Floodway" means 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.
(V) "Floodproofing" means any combination of
			 structural and non-structural 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.
(W) "Functionally dependent use"
			 means a use which 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

			 department of the interior) or preliminarily determined by the secretary of the
			 United States department of the interior as meeting the requirements for
			 individual listing on the National Register;
