Accessory Structure
An accessory structure is a structure which is on the same parcel of property as a principal structure and the use of which is incidental to the use of the principal structure. For example a residential structure may have a detached garage or storage shed for garden tools as accessory structures. Other examples of accessory structures include gazebos, picnic pavilions, boathouses, small pole barns, storage sheds, and similar buildings. National Flood Insurance Program (NFIP) regulations for new construction generally apply to new and substantially improved accessory structures.
Act
The National Flood Insurance Act of 1968 and any amendments to it.
Actual Cash Value (ACV)
The cost to replace an insured item of property at the time of loss, less the value of physical depreciation.
Addition
An addition is an improvement that increases the square footage of a structures. These include lateral additions added to the side or rear of a structure, vertical additions added on top of a structure and enclosures added underneath a structure. NFIP regulations for new construction apply to an addition that is considered to be a substantial improvement to a structure. Some states and communities require that all additions, regardless of their size, meet those requirements.
National Flood Insurance Program Requirements
Agricultural Structure
A structure used solely for agricultural purposes in which the use is exclusively in connection with the production, harvesting, storage, drying, or raising of agricultural commodities, including the raising of livestock. Communities must require that new construction or substantial improvements of agricultural structures be elevated or floodproofed to or above the Base Flood Elevation (BFE) as any other nonresidential building.
Alluvial Fan Flooding
Flooding occurring on the surface of an alluvial fan or similar landform which originates at the apex and is characterized by high-velocity flows; active processes of erosion, sediment transport, and deposition; and unpredictable flowpaths. Alluvial fan flooding is depicted on a Flood Insurance Rate Map (FIRM) as Zone AO, with a flood depth and velocity.

- 59.1 - Definition
Alteration of a Watercourse
Alterations are often made to the channels of rivers, stream, or drainageways, usually to improve drainage, relocate the channel, or to increase its flood carrying capacity. There are two requirements for maintaining the flood carrying capacity of an altered watercourse. The altered or relocated watercourse must have the same or greater capacity as the original watercourse. Additionally, once the alteration is made, the capacity of the altered or relocated watercourse must be maintained over time.
Alternative Rating
A rating method used when a building is Pre-FIRM, the Flood Insurance Rate Map (FIRM) zone is unknown, and the community in which the building is located has no V Zones. May also be used for renewal of policies in communities that have converted from the Emergency Program to the Regular Program during a policy's term.
Anchored
Adequately secured to prevent flotation, collapse or lateral movement.
Anchoring
If a proposed building site is in a flood-prone area, all new construction and substantial improvements shall be designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy. There are specific requirements for manufactured homes and structures in V Zones.
National Flood Insurance Program Requirements
Applicant
An individual or the head of a household who has applied for Federal disaster assistance. 44 CFR 206.111
Application
The statement made and signed by the prospective policyholder or the agent/producer in applying for an NFIP flood insurance policy. The Application gives information used to determine the eligibility of the risk, the kind of policy to be issued, and the correct premium payment. The Application is part of the flood insurance policy. For a policy to be issued, the correct premium payment must accompany the Application.
Assignment
The transfer by a policyholder of his/her legal right or interest in a policy contract to a third party. In the NFIP, written assignment of a policy is permissible upon transfer of title without the consent of the FEMA, except in the case where a residential (household) contents-only policy is involved or a policy was issued to cover a building in the course of construction.
Available Data
When a community has Zone A areas without elevation and/or floodway data, the community shall obtain, review and reasonably utilize Base Flood Elevation (BFE) and floodway data available from a Federal, State, or other source, including data developed pursuant to paragraph 60.3 (b) (3), as criteria for requiring that new construction, substantial improvement, or other development in Zone A on the community's Flood Insurance Rate Map (FIRM) or Flood Boundary and Floodway Map (FBFM) meet floodplain management standards.
Base Flood

FEMA sends the Biennial Report form to local community officials. Submission of this report is required as part of a community's participation in the NFIP.
National Flood Insurance Program Requirements
Binder or Certificate of Insurance
A temporary agreement between company, agent/producer and insured that the policy is in effect. The NFIP does not recognize binders. However, for informational purposes only, the NFIP recognizes Certificates of Insurance and similar forms for renewal policies.
Blanket Insurance
A single amount of insurance applying to more than 1 building and/or contents. Blanket insurance is not permitted under the NFIP
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 supporting foundation system.
Building
A structure with 2 or more outside rigid walls and a fully secured roof, that is affixed to a permanent site; or
Building in the Course of Construction

Cancellation
The termination of the insurance coverage provided by a policy before the expiration date.
Certifications
Certain activities (e.g., floodproofing design, V-Zone construction design, survey of building elevations, hydrologic and hydraulic analyses, survey and topographic data) require certification by a licensed professional architect, engineer, surveyor, or the community floodplain administrator.
National Flood Insurance Program Requirements
Cistern
Covered cisterns and the water in them are defined as an integral part of an insurable building, meaning under the building or above ground and physically attached to a side of the building with 1 of the walls of the building and cistern being common to each other.
Closed Basin Lake
A natural lake from which water leaves primarily through evaporation and whose surface area exceeds or has exceeded 1 square mile at any time in the recorded past. NFIP-insured buildings that are subject to continuous lake flooding from a closed basin lake are covered under the provisions of Standard Flood Insurance Policy (SFIP).
Coastal Barrier
A naturally occurring island, sandbar or other strip of land, including coastal mainland, that protects the coast from severe wave wash.
Coastal Barrier Improvement Act of 1990 (CBIA)
Enacted on November 16, 1990, the Act greatly expanded the identified land in the Coastal Barrier Resources System (CBRS) established pursuant to the Coastal Barrier Resources Act (CBRA) of 1982.
Coastal Barrier Resources Act of 1982 (CBRA)
For the purposes of the NFIP, the CBRA of 1982 designated certain portions of the Gulf and East Coasts as undeveloped coastal barriers. These areas are shown on appropriate flood insurance map panels and have certain coverage restrictions.
Coastal High Hazard Areas
Special Flood Hazard Areas (SFHAs) along the coasts that have additional hazards due to wind and wave action. These areas are identified on Flood Insurance Rate Maps (FIRMs) as zones V, V1-V30 and VE.
Coinsurance
A penalty imposed on the loss payment unless the amount of insurance carried on the damaged building is at least 80% of its replacement cost or the maximum amount of insurance available for that building under the NFIP, whichever is less. Coinsurance applies only to building coverage under the Residential Condominium Building Association Policy (RCBAP).
Community
- A group of people living in the same locality and under the same government, or a political subdivision of a state or other authority that has zoning and building code jurisdiction over a particular area.
- A political entity that has the authority to adopt and enforce floodplain ordinances for the area under its jurisdiction.
- A network of individuals and families, businesses, governmental and nongovernmental organizations and other civic organizations that reside or operate within a shared geographical boundary and may be represented by a common political leadership
Community Assistance Visit (CAV)
A major component of the National Flood Insurance Program's (NFIP's) Community Assistance Program (CAP). The CAV is a visit to a community by a FEMA staff member or staff of a State agency on behalf of FEMA that serves the dual purpose of providing technical assistance to the community and assuring that the community is adequately enforcing its floodplain management regulations. Generally, a CAV consists of a tour of the floodplain, an inspection of community permit files, and meetings with local appointed and elected officials.
Community Compliance Program
The National Flood Insurance Act of 1968 prohibits the Federal Emergency Management Agency (FEMA) from providing flood insurance in a community unless that community adopts and enforces floodplain management regulations that meet minimum National Flood Insurance Program (NFIP) criteria. When administrative problems or potential violations are identified in a community, FEMA is committed to working with that community and providing technical assistance to help them bring their floodplain management programs into compliance with NFIP requirements.
Community Number
A 6-digit designation identifying each NFIP community. The first 2 numbers are the state code. The next 4 are the FEMA-assigned community number. An alphabetical suffix is added to a community number to identify revisions in the Flood Insurance Rate Map (FIRM) for that community.
Community Rating System (CRS)
A program developed by FEMA to provide incentives for those communities in the Regular Program that have gone beyond the minimum floodplain management requirements to develop extra measures to provide protection from flooding.
Compensatory Storage
The NFIP floodway standard in 44CFR 60.3 (d) restricts new development from obstructing the flow of water and increasing flood heights. However, this provision does not address the need to maintain flood storage. Especially in flat areas, the floodplain provides a valuable function by storing floodwaters. When fill or buildings are placed in the flood fringe, the flood storage areas are lost and flood heights will go up because there is less room for the floodwaters. This is particularly important in smaller watersheds which respond sooner to changes in the topography.
Conditional Letter of Map Revision (CLOMR)
FEMA's comment on a proposed project that would, upon construction, affect the hydrologic or hydraulic characteristics of a flooding source and thus result in the modification of the existing regulatory floodway, the effective Base Flood Elevations (BFEs), or the Special Flood Hazard Area (SFHA). The letter does not revise an effective NFIP map, it indicates whether the project, if built as proposed, would be recognized by FEMA. FEMA charges a fee for processing a CLOMR to recover the costs associated with the review.
Condominium Association
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.
Contract Agent
An employee of a Write Your Own (WYO) Company or an agent/producer under written contract with a WYO Company, empowered to act on the company’s behalf and with authority to advise an applicant for flood insurance that the company will accept the risk.
Countywide Map
A Flood Insurance Rate Map (FIRM) that shows flooding information for the entire geographic area of a county, including the incorporated communities within the county.
Crawlspace
a. Crawlspace foundations are commonly used in some parts of the nation to elevate the lowest floors of residential buildings located in Special Flood Hazard Areas (SFHAs) above the Base Flood Elevation (BFE). Crawlspaces should be constructed so that the floor of the crawlspace is at or above the lowest grade adjacent to the building. Crawspaces that have their floors below BFE must have openings to allow the equalization of flood forces.
Critical Facility
For some activities and facilities, even a slight chance of flooding is too great a threat. Typical critical facilities include hospitals, fire stations, police stations, storage of critical records, and similar facilities. These facilities should be given special consideration when formulating regulatory alternatives and floodplain management plans. A critical facility should not be located in a floodplain if at all possible.
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.
Date of Construction
The date that the building permit was issued, provided the actual start of construction, repair, reconstruction or improvement was within 180 days of the permit date.
Declarations Page
A computer-generated summary of information provided by the prospective policyholder in the application for flood insurance. The declarations page also describes the term of the policy and the limits of coverage and displays the premium and the insurer's name. The declarations page is a part of the flood insurance policy.
Deductible
The fixed amount of an insured loss that is the responsibility of the insured and that is incurred before any amounts are paid for the insured loss under the insurance policy.
Described Location
The location where the insured building or personal property is found. The described location is shown on the Declarations Page.
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. A community without a Flood Insurance Rate Map (FIRM) or Flood Hazard Boundary Map (FHBM) must require a permit for all proposed construction or other development in the community, so that it can determine whether the construction or other development is proposed within a flood-prone area.
Diagram Number
Any of the numbers used in the instructions to the NFIP Elevation Certificate to identify the diagrams of the main types of buildings.
Doublewide Manufactured (Mobile) Home
A manufactured (mobile) home that, when assembled as a nonmovable, permanent building, is at least 16 feet wide and has an area within its perimeter walls of at least 600 square feet.
Dwelling
A building designed for use as a residence for no more than 4 families or a single-family unit in building under a condominium form of ownership.
Dwelling Form
See Standard Flood Insurance Policy (SFIP)--Dwelling Form.
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) foundations walls are not an acceptable means of elevating buildings in V and VE zones.
Elevation Certificate
A community's permit file must have an official record that shows new buildings and substantial improvements in all identified Special Flood Hazard Areas (SFHAs)are properly elevated. This elevation information is needed to show compliance with the floodplain management ordinance. FEMA encourages communities to use the Elevation Certificate developed by FEMA to fulfill this requirement since it also can be used by the property owner to obtain flood insurance.
Elevators
The National Flood Insurance Program (NFIP) regulations require that elevators and their associated equipment be protected from flood damage. The best way to do this is to locate mechanical equipment associated with the elevator above the Base Flood Elevation (BFE). NFIP flood insurance coverage is limited for elevator equipment. New or replacement equipment relevant to an elevator, installed on or after October 1, 1987, and located below the lowest floor of an elevated building or in a basement is not covered by flood insurance.
Emergency Program
The initial phase of a community's participation in the National Flood Insurance Program, as prescribed by Section 1306 of the Act.
Enclosure
That portion of an elevated building below the lowest elevated floor that is either partially or fully shut in by rigid walls.
Encroachments
Encroachments are activities or construction within the floodway including fill, new construction, substantial improvements, and other development. These activities are prohibited within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses that the proposed encroachment would not result in any increase in flood levels.
Erosion
a. The collapse, undermining or subsidence of land along the shore of a lake or other body of water. Erosion is a covered peril if it is caused by waves or currents of water exceeding their cyclical levels which result in flooding.
Existing Construction
For the purposes of determining flood insurance rates, structures for which the "start of construction" commenced before the effective date of the Flood Insurance Rate Map (FIRM) or before January 1, 1975, for FIRMs effective before that date. "Existing construction" may also be referred to as "existing structures."

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.
Fill
Earthen fill is sometimes placed in an Special Flood Hazard Area (SFHA) to reduce flood risk to the filled area. The placement of fill is considered development and will require a permit under applicable Federal, state and local laws, ordinances, and regulations. Fill is prohibited within the floodway unless it has been demonstrated that it will not result in any increase in flood levels. Some communities limit the use of fill in the flood fringe to protect storage capacity or require compensatory storage. The use of fill is prohibited for structural support of buildings in V Zones.
Financial Assistance/Subsidy Arrangement
The arrangement between an insurance company and FEMA to initiate the company's participation in the Write Your Own (WYO) Program. It establishes the duties of the company and the government.
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

Flood Hazard Boundary Map (FHBM)
Official map of a community issued by FEMA, where the boundaries of the flood, mudflow and related erosion areas having special hazards have been designated.
Flood Hazards of Special Concern
The mapping and regulatory standards of the National Flood Insurance Program (NFIP) are general standards and do not address every flood problem in the United States. Certain floodplains and flood-related hazards are less common, more destructive and harder to map than riverine, coastal, alluvial fan, and shallow flooding. Special hazards include coastal erosion, tsunamis, closed basin lakes, uncertain flow paths, dam breaks, ice jams, and mudflows.
Flood Insurance Rate Map (FIRM)
Official map of a community on which FEMA has delineated the Special Flood Hazard Areas (SFHAs), the Base Flood Elevations (BFEs) and the risk premium zones applicable to the community.

Flood Insurance Study (FIS)
A compilation and presentation of flood risk data for specific watercourses, lakes, and coastal flood hazard areas within a community. When a flood study is completed for the NFIP, the information and maps are assembled into an FIS. The FIS report contains detailed flood elevation data in flood profiles and data tables.
Flood Response Office (FRO)
The FRO provides a local presence in the affected area and supports the WYO companies, the NFIP Servicing Agent and various Federal, state and local officials in providing answers to claims coverage questions, forms for claims handling and survey and statistical input. One of the key requirements of personnel at the FRO is to coordinate and conduct reinspections of WYO and NFIP Direct losses. The FRO also tracks adjuster performance and provides such information to interested WYO Companies and the NFIP Servicing Agent.
Flood Zones
Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30.
Flood-Related Erosion
The collapse or subsidence of land along the shore of a lake or other body of water as a result of undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as a flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding.
National Flood Insurance Program Requirements
- 59.1 - Definition
Flood-Resistant Material
Flood-resistant material includes any building product capable of withstanding direct and prolonged contact with floodwaters without sustaining significant damage. Prolonged contact is defined as at least 72 hours. Significant damage is any damage requiring more than low-cost cosmetic repair (such as painting). All structural and non-structural building materials at or below the Base Flood Elevation (BFE) must be flood resistant.
National Flood Insurance Program Requirements
60.3 (a)(3) - Reasonably Safe from Flooding
Floodplain
Any land area susceptible to being inundated by floodwaters from any source.
Floodplain Management
a. The operation of an overall program of corrective and preventive measures for reducing flood damage, including but not limited to, emergency preparedness plans, flood-control works and floodplain management regulations.
b. Floodplain management is a decision-making process that aims to achieve the wise use of the nation's floodplains. "Wise use" means both reduced flood losses and protection of the natural resources and function of floodplains.
Floodplain Management Ordinances
Once FEMA provides a community with the flood hazard information upon which floodplain management regulations are based, the community is required to adopt a floodplain management ordinance that meets or exceeds the minimum NFIP requirements. The overriding purpose of the floodplain management regulations is to ensure that participating communities take into account flood hazards, to the extent that they are known, in all official actions relating to land management and use. The specific requirements are in Section 60.3 of the NFIP regulations, and apply to communities as follows:
Floodproofing
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.
Floodproofing Certificate
Documentation of certification by a registered professional engineer or architect that the design and methods of construction of a nonresidential building are in accordance with accepted practices for meeting the floodproofing requirements in the community's floodplain management ordinance. This documentation is required for both floodplain management requirements and insurance rating purposes.
Floodway
A "Regulatory 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. Communities must regulate development in these floodways to ensure that there are no increases in upstream flood elevations.
Foundation
Without a proper foundation, an elevated building can suffer damage from a flood due to erosion, scour, or settling. The National Flood Insurance Program (NFIP) regulations provide performance standards for anchoring new buildings and foundation and fill placement standards for buildings, for manufactured homes, and in V Zones. However, the NFIP performance standards do not specify how a building's foundations are to be constructed in A Zones. The national model building codes address building foundations and the proper placement, compaction, and protection of fill.
Foundation Walls
Masonry walls, poured concrete walls or precast concrete walls, regardless of height, that extend above grade and support the weight of a building.
Freeboard
a. An additional amount of height above the Base Flood Elevation used as a factor of safety (e.g., 2 feet above the Base Flood) in determining the level at which a structure's lowest floor must be elevated or floodproofed to be in accordance with state or community floodplain management regulations.
Full-Risk Premium Rate
A rate charged to a group of policies that results in aggregate premiums sufficient to pay anticipated losses and expenses for that group.
Functionally Dependent Use
A use which cannot perform its intended purpose unless it is located or carried out in close proximity to water. This term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and shipbuilding and ship repair facilities, but does not include long-term storage or related manufacturing facilities.
Garages
Attached Garages A garage attached to a residential structure or in an enclosed area below an elevated building may have the garage floor slab below the Base Flood Elevation (BFE). Because such a garage is an enclosed area below the BFE, openings are required either in the exterior walls of the garage or in the garage doors themselves.
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).
Group Flood Insurance
Issued by the NFIP Direct Program in response to a Presidential disaster declaration. Disaster assistance applicants, in exchange for a modest premium, receive a minimum amount of building and/or contents coverage for a 3-year policy period. An applicant may cancel the group policy at any time and secure a regular Standard Flood Insurance Policy (SFIP) through the NFIP.
High Hazard Area
An area of special flood hazard extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources. The coastal high hazard area is identified as Zone V on Flood Insurance Rate Maps (FIRMs). Special floodplain management requirements apply in V Zones including the requirement that all buildings be elevated on piles or columns.
High-Rise Building
High-rise condominium buildings have 5 or more units and at least 3 floors excluding enclosure even if it is the lowest floor for rating purposes. An enclosure below an elevated building, even if it is the lowest floor for rating purposes, cannot be counted as a floor to avoid classifying the building as low rise. Under the NFIP, townhouses/rowhouses are not considered high-rise buildings, regardless of the number of floors.
Higher Standard
Federal Emergency Management Agency (FEMA) has established minimum floodplain management requirements for communities participating in the National Flood Insurance Program (NFIP). Communities must also enforce any more restrictive state requirements. Any community may exceed the minimum standards by adopting more comprehensive floodplain management regulations. In some instances, community officials may have access to information or knowledge of conditions that require, particularly for human safety, higher standards than the minimum NFIP criteria.
Highest Adjacent Grade
The highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure. In AO Zones, all new construction and substantial improvements of residential structures shall have the lowest floor including basement elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's Flood Insurance Rate Map (FIRM); or at least two feet if no depth number is specified.
Hydrodynamic Forces
Hydrodynamic forces are imposed on an object, such as a building, by water flowing against and around it. Among the forces are positive frontal pressure against the structure, drag effect along the sides, and negative pressure in the downstream side. Hydrodynamic forces are one of the main causes of flood damage.Typical areas where hydrodynamic forces are of particular concern are along rivers and streams with high velocity floodwaters and coastal and other areas subject to wave forces.
Hydrostatic Forces
Standing water or slowly moving water can induce horizontal hydrostatic forces against a structure, especially when floodwater levels on different sides of a wall are not equal. Also flooding can cause vertical hydrostatic forces, or flotation. Hydrostatic forces are one of the main causes of flood damage.
Improvements and Betterments
Fixtures, alterations, installations or additions made or acquired solely at a tenant’s expense and comprising part of an insured building.
Increased Cost of Compliance
Coverage for expenses that a property owner must incur, above and beyond the cost to repair the physical damage the structure 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.
Indian Tribes
Indian tribes, authorized tribal organizations, Alaska Native villages or authorized native organizations, which have land use authority, are considered communities by the National Flood Insurance Program (NFIP) and can join the program even if no flood hazard map exists that covers all tribal lands.
Letter of Determination Review (LODR)
FEMA's ruling on the determination made by a lender or third party that a borrower's building is in a Special Flood Hazard Area (SFHA). A LODR deals only with the location of a building relative to the SFHA boundary shown on the Flood Insurance Rate Map (FIRM).
Letter of Map Amendment (LOMA)
An amendment to the currently effective FEMA map which establishes that a property is not located in a Special Flood Hazard Area (SFHA). A LOMA is issued only by FEMA.
Letter of Map Change (LOMC)
Letter of Map Change (LOMC) is a general term used to refer to the several types of revisions and amendments to FEMA maps that can be accomplished by letter. They include Letter of Map Amendment (LOMA), Letter of Map Revision (LOMR), and Letter of Map Revision based on Fill (LOMR-F).
Letter of Map Revision (LOMR)
A Letter of Map Revision is FEMA's modification to an effective Flood Insurance Rate Map (FIRM), or Flood Boundary and Floodway Map (FBFM), or both. Letter of Map Revisions are generally based on the implementation of physical measures that affect the hydrologic or hydraulic characteristics of a flooding source and thus result in the modification of the existing regulatory floodway, the effective Base Flood Elevations (BFEs), or the Special Flood Hazard Area (SFHA).
Letter of Map Revision Based on Fill (LOMR-F)
A Letter of Map Revision Based on Fill (LOMR-F) is FEMA's modification of the Special Flood Hazard Area (SFHA) shown on the Flood Insurance Rate Map (FIRM) based on the placement of fill outside the existing regulatory floodway.
All requests for changes to effective maps, other than those initiated by FEMA, must be made in writing through the Chief Executive Officer (CEO) of the community or an official designated by the CEO.
Loss in Progress
A loss that is already in progress as of 12:01 a.m. on the first day of the policy term; or, as to any increase in the limits of coverage which is requested, a loss that is already in progress when the additional coverage is requested.
Low-Rise Building
Low-rise condominium buildings having fewer than 5 units regardless of the number of floors or 5 or more units with fewer than 3 floors including basement. All townhouses/rowhouses, regardless of the number of floors or units and all single-family detached condominium buildings are classified as low rise. An enclosure below an elevated building, even if it is the lowest floor for rating purposes, cannot be counted as a floor to avoid classifying the building as a low rise.
Lowest Floor
The lowest floor of the lowest enclosed area (including a 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 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.
Lowest Horizontal Structural Member
In V Zones, new construction must have the elevation of the lowest horizontal structural member at or above the Base Flood Elevation (BFE). Horizontal structural members are obstructions and can transmit the force of wave impacts to rest of the structure. This elevation is used as the reference level to determine insurance rates. This contrasts with construction and insurance rating in A Zones, which uses the elevation of the lowest floor including basement as the reference level.
Mandatory Purchase
Under the provisions of the Flood Disaster Protection Act of 1973, individuals, businesses and others buying, building or improving property located in identified areas of special flood hazards within participating communities are required to purchase flood insurance as a prerequisite for receiving any type of direct or indirect federal financial assistance (e.g., any loan, grant, guaranty, insurance, payment, subsidy or disaster assistance) when the building or personal property is the subject of or security for such assistance.

Wave Height Adjustment
A measurement that is added to the Base Flood Elevation (BFE) for V Zones shown on the Flood Insurance Rate Map (FIRM) published prior to 1981. For coastal communities, the BFE shown on FIRMs published prior to 1981 are stillwater elevations, which include only the effects of tide and storm surge and not the height of wind-generated waves.
Wet Floodproofing
Wet Floodproofing includes permanent or contingent measures applied to a structure or its contents that prevent or provide resistance to damage from flooding while allowing floodwaters to enter the structure or area. Generally, this includes properly anchoring the structure, using flood resistant materials below the Base Flood Elevation (BFE), protection of mechanical and utility equipment, and use of openings or breakaway walls.
Write Your Own (WYO) Program

Zone
A geographical area shown on a Flood Hazard Boundary Map (FHBM) or a Flood Insurance Rate Map (FIRM) that reflects the severity or type of flooding in the area.
Zone A
Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30‐year mortgage. Because detailed analyses are not performed for such areas; no depths or base flood elevations are shown within these zones.
Zone A1-30
These are known as numbered A Zones (e.g., A7 or A14). This is the base floodplain where the FIRM shows a BFE (old format).
Zone A99
Areas with a 1% annual chance of flooding that will be protected by a Federal flood control system where construction has reached specified legal requirements. No depths or base flood elevations are shown within these zones.
Zone AE
The base floodplain where base flood elevations are provided. AE Zones are now used on new format FIRMs instead of A1‐A30 Zones.
Zone AH
Areas with a 1% annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. These areas have a 26% chance of flooding over the life of a 30‐year mortgage. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.
Zone AO
River or stream flood hazard areas, and areas with a 1% or greater chance of shallow flooding each year, usually in the form of sheet flow, with an average depth ranging from 1 to 3 feet. These areas have a 26% chance of flooding over the life of a 30‐year mortgage. Average flood depths derived from detailed analyses are shown within these zones.
Zone AR
Areas with a temporarily increased flood risk due to the building or restoration of a flood control system (such as a levee or a dam). Mandatory flood insurance purchase requirements will apply, but rates will not exceed the rates for unnumbered A zones if the structure is built or restored in compliance with Zone AR floodplain management regulations.
Zone B and X (Shaded)
Area of moderate flood hazard, usually the area between the limits of the 100‐ year and 500‐year floods. B Zones are also used to designate base floodplains of lesser hazards, such as areas protected by levees from 100‐year flood, or shallow flooding areas with average depths of less than one foot or drainage areas less than 1 square mile.
Zone C or X (Unshaded)
Area of minimal flood hazard, usually depicted on FIRMs as above the 500‐year flood level. Zone C may have ponding and local drainage problems that don't warrant a detailed study or designation as base floodplain. Zone X is the area determined to be outside the 500‐year flood and protected by levee from 100‐ year flood.
Zone D
Areas with possible but undetermined flood hazards. No flood hazard analysis has been conducted. Flood insurance rates are commensurate with the uncertainty of the flood risk.
Zone V
Coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves. These areas have a 26% chance of flooding over the life of a 30‐year mortgage. No base flood elevations are shown within these zones.
Zone VE and V1-30
Coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves. These areas have a 26% chance of flooding over the life of a 30‐year mortgage. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.
