Glossary of Terms

Actual Cash Value (ACV)

 The cost to replace an insured item of property at the time of loss, less the value of its physical depreciation.

Base Flood

A flood having a 1% chance of being equaled or exceeded in any given year.

Base Flood Elevation (BFE)

The elevation of surface water resulting from a flood that has a 1% chance of equaling or exceeding that level in any given year. The BFE is shown on the Flood Insurance Rate Map (FIRM) for zones AE, AH, A1–A30, AR, AR/A, AR/AE, AR/A1– A30, AR/AH, AR/AO, V1–V30, and VE.

Basement

Any area of the building, including any sunken room or sunken portion of a room, having its floor below ground level (subgrade) on all sides.

Community

A political entity that has the authority to adopt and enforce floodplain ordinances for the area under its jurisdiction.

Condominium

The entity made up of the unit owners responsible for the maintenance and operation of the following: • Common elements owned in undivided shares by unit owners • Other real property in which the unit owners have use rights; where membership in the entity is a required condition of unit ownership.

Condominium Building

A type of building in the form of ownership in which each unit owner has an undivided interest in common elements of the building.

Crawlspace

 An under-floor space that has its interior floor area (finished or not) no more than 5 feet below the top of the next-higher floor. Crawlspaces generally have solid foundation walls. See Diagram 8 in the Elevation Certificate Instructions.

Cumulative Damage Building

Any building that has incurred flood-related damage as a result of two or more flooding events in which the cumulative amounts of payments equals or exceeds the fair market value of such building, as determined through use of the following procedure. To determine whether a building has been cumulatively damaged, a loss percentage will be calculated, for each loss, equal to the claim payment amount for that loss divided by the fair market value of such building on the day before each loss. If the sum of the loss percentages for more than one loss equals or exceeds 100%, then the property will be deemed a cumulative damage building.

Elevated Building

A building that has no basement and that has its lowest elevated floor raised above ground level by foundation walls, shear walls, posts, piers, pilings, or columns. Solid (perimeter) foundation walls are not an acceptable means of elevating buildings in V and VE Zones.

Enclosure

That portion of an elevated building below the lowest elevated floor that is either partially or fully shut in by rigid walls.

Federal Policy Fee

A flat charge that the policyholder must pay on each new or renewal policy to defray certain administrative expenses incurred in carrying out the NFIP.

Finished (Habitable) Area

An enclosed area having more than 20 linear feet of finished interior walls (paneling, etc.) or used for any purpose other than solely for parking of vehicles, building access, or storage.

Flood

• A general and temporary condition of partial or complete inundation of 2 or more acres of normally dry land area or of 2 or more properties (at least 1 of which is the policyholder’s property) from: º Overflow of inland or tidal waters; º Unusual and rapid accumulation or runoff of surface waters from any source; or º Mudflow; or • Collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels that result in a flood as defined above.

FLoodplain

Any land area susceptible to being inundated by floodwaters from any source.

Foundation Walls

Masonry walls, poured concrete walls, or precast concrete walls, regardless of height, that extend above grade and support the loads of 

 a building.

Freeboard

An additional amount of height above the Base Flood Elevation (BFE) used as a factor of safety (e.g., 2 feet above the Base Flood) in determining the level at which a building’s lowest floor must be elevated or floodproofed to be in accordance with state or community floodplain management regulations.

Grade Elevation

The lowest or highest finished ground level that is immediately adjacent to the walls of the building. Use natural (pre-construction), ground level, if available, for Zone AO and Zone A (without BFE).

Grandfathering

An exemption based on circumstances previously existing.  • Under NFIP statutory grandfathering, buildings located in Emergency Program communities and PreFIRM buildings in the Regular Program are eligible for subsidized flood insurance rates.

HFIAA Surcharge

 The statutory surcharge imposed by Section 1308 of the Act. 

Increased Cost of Compliance (ICC)

Coverage for expenses that a property owner must incur, above and beyond the cost to repair the physical damage the building actually sustained from a flooding event, to comply with mitigation requirements of state or local floodplain management ordinances or laws. Acceptable mitigation measures are elevation, floodproofing, relocation, demolition, or any combination thereof.

Lowest Adjacent Grade

The lowest point of the ground level immediately next to a building.

Lowest Floor

The lowest floor of the lowest enclosed area (including a basement). An unfinished or floodresistant 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 enclosure is not built so as to render the structure in violation of requirements

Lowest Floor Elevation (LFE)

 The measured distance of a building’s lowest floor above the National Geodetic Vertical Datum (NGVD) or other datum specified on the FIRM for that location.


Masonry Walls

Walls constructed of individual components laid in and bound together with mortar. 

These components can be brick, stone, concrete block, etc.


New Construction

Buildings for which the “start of construction” commenced on or after the effective date of an initial Flood Insurance Rate Map (FIRM) or after December 31, 1974, whichever is later, including any subsequent improvements.

Newly Mapped (A Property Newly Mapped into the SFHA)

 A property that was once designated outside of the Special Flood Hazard Area (SFHA) on an effective Flood Insurance Rate Map (FIRM), and following a map revision, is designated within the SFHA. Property newly mapped into the SFHA by a map revision on or after April 1, 2015, and meeting certain loss history requirements is eligible for the Newly Mapped rating procedure outlined in the Newly Mapped section of this manual if coverage is purchased within 1 year of the map revision and continuously maintained. A property meeting the loss history requirements and newly mapped into the SFHA by a map revision effective on or after October 1, 2008, and before April 1, 2015, may be insured under the Newly Mapped rating procedure if coverage is purchased on or after April 1, 2015, but before April 1, 2016, and maintained continuously. The newly mapped procedure is not available for any property mapped into the SFHA by the initial FIRM.


Non-Primary Residence

A residential building that is not the primary residence of the policyholder.

Preferred Risk Policy (PRP)

 A lower-cost Standard Flood Insurance Policy (SFIP), written under the Dwelling Form or General Property Form. It offers fixed combinations of building/contents coverage limits or contents-only coverage. The PRP is available for property located in B, C, and X Zones in Regular Program communities that meets eligibility requirements 

 based on the property’s flood loss history. It is also available for buildings that are eligible under the PRP Eligibility Extension.


Primary Residence

A single family building, condominium unit, apartment unit, or unit within a cooperative building that will be lived in by the policyholder or the policyholder’s spouse for:

1. More than 50% of the 365 calendar days following the current policy effective date; or 2. 50% or less of the 365 calendar days following the current policy effective date if the policyholder has only one residence and does not lease that residence to another party or use it as rental or income property at any time during the policy term. A policyholder and the policyholder’s spouse may not collectively have more than one primary residence.

Special Flood Hazard Area (SFHA)

 An area having special flood, mudflow, or flood-related erosion hazards, and shown on a Flood Hazard Boundary Map (FHBM) or Flood Insurance Rate Map (FIRM) as Zone A, AO, A1–A30, AE, A99, AH, AR, AR/A, AR/AE, AR/ AH, AR/AO, AR/A1–A30, V1–V30, VE, or V. For the purpose of determining Community Rating System (CRS) premium discounts, all AR and A99 Zones are treated as non-SFHAs.


Subgrade Crawlspace

 A crawlspace foundation where the subgrade under-floor area is no more than 5 feet below the top of the next-higher floor and no more than 2 feet below the lowest adjacent grade on all sides.


Substantially Damaged Building
