Instructions:

Fill is defined as material from any source (including the subject property) placed on the property that raises the ground (natural grade) to or above the Base Flood Elevation (BFE).

The common construction practice of removing unsuitable existing material (topsoil) and backfilling with select structural material is not considered the placement of fill if the practice does not alter the existing (natural grade) elevation, which is at or above the BFE. If the fill was placed before the date of the first National Flood Insurance Program (NFIP) map showing the area in a Special Flood Hazard Area, the area that would be inundated by the base flood, is considered natural grade.

Regardless of the type of LOMC being requested, DHS-FEMA requires the applicant to confirm, to the best of his or her knowledge, whether fill was or was not placed on the property. The applicant must select either "yes" or "no". If fill was placed on the property, the applicant must provide the month and year fill was placed.

If fill has not been placed on the property to raise ground that is below the BFE, DHS-FEMA requires the applicant to confirm whether they plan for fill to be placed on the property in the future by selecting "yes" or "no". If fill will be placed on the property, the applicant must provide the month and year fill will be placed.

Assistance to ascertain if fill has been placed on your property may be available from the community official or agency responsible for floodplain management. Requesters should consult with the community map repository to obtain previous editions of the NFIP map, archived topographic data, or permit drawings related to construction on the site. If the structure footprint is located on ground higher than the surrounding area, fill may have been placed. Additional sources for assistance would include the developer or engineer/designer of the subdivision, previous owners of the site, persons who have owned or resided on adjacent parcels, and large scale aerial photographs (check the tax assessor's office). In addition, digital copies of historic NFIP maps may be available on DHS-FEMA's Map Service Center (MSC) for a nominal fee. To place orders from the MSC, interested parties may visit the MSC website at https://www.msc.fema.gov. For additional information regarding historic maps, interested parties should contact the DHS-FEMA Mapping and Information eXchange, toll free, at 1-877-FEMA MAP (1-877-336-2627).

Community Acknowledgment Form

The Community Acknowledgment Form (DHS-FEMA Form 086-0-26B, FEB11) must be completed for all requests involving the placement of fill, existing or proposed, or requests for land or structures that are inadvertently included in the NFIP regulatory floodway. The form must be completed and signed by the community official responsible for floodplain management in the community. The community name and the subject property address shown provided earlier in the Online LOMC process must appear in the spaces provided on this form. Space has been provided within each section for the community official to provide comments on the project (e.g., Section A - The project is reasonably safe from flooding and satisfies Parts 60.3 and 65.5 of the NFIP regulations. Section B - Removal of the project from the regulatory floodway will not result in an increase in Base Flood Elevations.). If additional space is required by the community official to provide the community's comments on a project, additional sheets may be added to the back of the form when uploaded to the Online LOMC application.

How to Complete the Elevation Form:

The Elevation Form (DHS-FEMA Form 086-0-26A, FEB11) must be completed by a licensed land surveyor or registered professional engineer (authorized by law to certify the information requested). If the request is to make a determination on the structure, and an NFIP Elevation Certificate has already been completed for this property, it may be submitted in lieu of this form.

If the request is to make a determination on the entire legally recorded property, or a portion thereof, the lowest lot elevation must be provided on the Elevation Form. If the request is to have the SFHA designation determined for the entire legally recorded property, but the only elevation provided is the Lowest Adjacent Grade to Structure, the determination will be issued for the structure.

For a licensed land surveyor or registered professional engineer to complete this form, it will be necessary to obtain the effective Flood Insurance Rate Map (FIRM) panel, effective Flood Boundary and Floodway Map (FBFM) panel (if printed), and Flood Insurance Study (FIS) report that cover the area in which the property is located. These can be obtained from the community map repository or ordered from the Map Service Center (MSC), for a nominal fee. To place orders from the MSC, go to their Internet site: https://www.msc.fema.gov.

The DHS-FEMA Map Service Center allows users, including homeowners, surveyors, and engineers, to search the MSC for maps and other technical data. Searches can be conducted under the three following criteria: Catalog, Map Search, and Quick Order. Catalog allows surveyors and engineers to search through the Map Service Center for available data. Map Search allows surveyors and engineers to search for data available for an individually specified map area. Quick Order allows surveyors and engineers to search available data by a specific FIRM panel or Community number. All search criteria will allow surveyors and engineers to search desired data and add that data to a "shopping cart" for later payment options. Payment must be in the form of a credit card. Visa, MasterCard, Discover and American Express are accepted. Surveyors and engineers that do not have Internet access should contact the DHS-FEMA Mapping and Information eXchange by calling 1-877-FEMA MAP (1-877-336-2627). They may fax their map order requests to the MSC at 1- 800-358-9620.

The following graphic is a demonstration of an elevation map. It displays three structures in relation to the Special Flood Hazard Area (SFHA). The yellow structure (far left) is an example of a strucure that is too close to definitely determine whether the structure is graphically outside the Special Flood Hazard Area on the FIRM. The red structure (middle) shows a structure that is clearly inside the Special Flood Hazard Area on the FIRM, therefore elevations should be submitted. The green structure (far right) is clearly shown outside of the Special Flood Hazard Area on the FIRM. Use the map as a guideline to determine the location of your property or structure in relation to the Special Flood Hazard Area. If your property or structure is clearly outside of a Special Flood Hazard Area, you may not have to submit the Elevation Form. Please be aware, not submitting this form will delay the processing of your request.

Number 1 – Community Number

Provide the six digit NFIP community number as it appears in the Title Block of the FIRM panel. In addition, include the name of the property (i.e. legal description) and/or the property's address.

NOTE: In some communities, the only NFIP maps available may be Flood Hazard Boundary Maps, instead of FIRMs.

Number 2 – Conditionals

Identify whether the elevations being provided are based on existing or proposed conditions.

Number 3 – Type of Construction

If the request involves or will involve a structure, provide the type of construction.

Crawl Space – The bottom floor is below the first floor, is enclosed by solid and partial perimeter walls, and may be above ground level (grade) on one or more sides. Spaces below ground level on all sides must meet the requirements of FEMA Technical Bulletin 11-01. Spaces with a bottom floor elevation more than 2.0 feet below the Lowest Adjacent Exterior Grade (LAG) elevation will be classified as a basement.

Slab on Grade – The bottom floor is at or above ground level (grade) on at least one side.

Basement/Enclosure – The bottom floor (basement or underground garage) is below ground level (grade) on all sides. See Crawl Space above.

Other – All other structure types not listed above including, but not limited to split levels, structures on piers, mobile homes, etc. Please be as detailed as possible.

Number 4 – Elevation Datum
Provide the elevation datum (e.g., NGVD 29, NAVD 88, or other specified) for which the property elevations shown on the form are referenced. If the datum being referenced is different than the datum used to produce the effective FIS, please provide the datum conversion. Please note that mean sea level datum (MSL) is used within the Commonwealth of Puerto Rico and local tidal datum (LTD) is used within the U.S. Virgin Islands.

Number 5 – Geographic Coordinate Data
The surveyor or engineer must provide the latitude and longitude of the property in decimal degrees to the 5th decimal place (00.00000), and indicate the appropriate horizontal datum, WGS84, NAD83, or NAD27.

Number 6 – Subsidence or Uplift

Land subsidence is the lowering of the ground as a result of water, oil, gas extraction, as well as other phenomena such as soil compaction, decomposition of organic material, and tectonic movement. Periodically, the National Geodetic Survey re-levels some benchmarks to determine new elevations above the National Geodetic Vertical Datum of 1929 (NGVD 29) or above the North American Vertical Datum of 1988 (NAVD 88); however, not all benchmarks are re-leveled each time.

Check "yes" if the area of the property is in an area of subsidence or uplift, and provide the date of the current re-leveling; check "no" if the area of the property is not in an area of subsidence or uplift. In areas experiencing ground subsidence (e.g., Harris County, Texas, and Incorporated Areas); the most recently adjusted Elevation Reference Mark (ERM) must be used for accurate ground and structure elevations. Please consult the effective Flood Insurance Study (FIS) for your community or local floodplain administrator for the most current ERM data.

In general, the effects of subsidence can be accounted for by determining grade and structure elevations using benchmark elevations with the same re-level date as the benchmarks used to develop the Base (1%-annual chance) Flood Elevations (BFEs) on the FIRM. Please be aware that benchmark re-level dates can be different for different flooding sources. No adjustment is necessary to the BFEs on the FIRM.

Elevation Table

A row in the elevation table must be completed for each property (parcels of land or structures) involved in this request (subject property).

• Riverine Flooding Systems (Zones AE or A1-A30) – Consult the FIS report for the community in which the property is located. Next, locate the flood profile for the flooding source by name. Estimate the property"s location along the flood profile and interpolate the BFE using the 100-yr. flood profile line.
  
• Lacustrine (Stillwater) Flooding Systems –Consult the FIS report for the community in which the property is located. Next, locate the Summary of Stillwater Elevations table. Locate the flooding source, by name, and use the BFE listed in the table. The flooding source's BFE is normally shown to the nearest one-tenth of a foot. If the flooding source is not listed in the "Summary of Stillwater Elevations" table, use the BFE as shown on the FIRM.
  
• Coastal Flooding Systems (Zones AE or A1-A30 and VE or V1-V30) –First, obtain the BFE from the FIRM panel. Next, consult the FIS report for the community in which the property is located. Locate the Summary of Stillwater Elevations table in the FIS report. Identify the flooding source, by name, and use the BFE listed in the table. Compare the BFE listed in this table to the BFE obtained from the FIRM. If the stillwater elevation listed in this table is less than or equal to the whole-foot BFE shown on the map minus 0.5 foot, a wave height, wave run-up, and/or wave setup component exists. In this case, the whole-foot BFE shown on the map should be used for rating, construction, and floodplain management purposes. If the stillwater elevation listed in the "Summary of Stillwater Elevations" table is greater than the wholefoot BFE shown on the map minus 0.4 foot, the stillwater elevation shown in the table shall be used as the BFE. (Any property/structure located seaward of the landward toe of the primary frontal dune may not be removed from a Zone VE or V1-V30).
  
• Zone A Flooding –If the property is located in a Zone A, an area of approximate flooding with no BFEs determined, a BFE will need to be determined by the engineer or surveyor. First, the engineer or surveyor should determine if a Federal, State, or local government agency has developed a BFE. Such agencies include the U.S. Army Corps of Engineers, the U.S. Geological Survey, the State's Department of Natural Resources, Department of Environmental Quality, or Department of Transportation; or the local Planning and Zoning Department. If one has been developed, all supporting data and calculations used to develop the BFE must be submitted, or a letter directly from the government agency must be submitted. If a BFE has not previously been developed, the engineer or surveyor should consult DHS-FEMA 265, Managing Floodplain Development in Approximate Zone A Areas: A Guide for Obtaining and Developing Base (100- year) Flood Elevations, available online at https://www.fema.gov/resource-document-library. This publication is an excellent resource, which details the appropriate methods for determining BFEs in SFHAs designated flood zone A. To obtain additional information about developing BFEs, contact the DHS-FEMA Mapping and Information eXchange at 1-877-FEMA MAP (1-877-336-2627). If the property is greater than 50 lots or 5 acres, whichever is the lesser, the engineer or surveyor must determine a BFE as a provision of Part 60.3(b)(3), which is available online at https://www.fema.gov/media-library/assets/documents/12442.
  
• Shallow Flooding (Zone AH) – If the property is located in flood zone AH, locate the Summary of Stillwater Elevations table in the FIS report. Identify the flooding source, by name, and use the BFE listed in the table. If no Summary of Stillwater Elevations table exists, use the BFE shown on the FIRM. If different elevations appear within the same SFHA, the BFE is obtained by linear interpolation between two adjacent BFE lines.
  
• Shallow/Sheet Flooding (Zone AO) – For a property located in Zone AO, the characteristics of the Zone AO area shown on the NFIP map will determine the appropriate methodology to be used to develop the BFE for the property. If the flooding is conveyed by the street, provide the highest top of curb or crown of street elevation (whichever is higher) along the property line and add this to the depth of flooding. The lowest adjacent grade elevation must be above the curb or street elevation by an amount equal to or greater than the depth of flooding shown on the NFIP map. If the entire property is inundated by the SFHA and the flow is not conveyed by the street, add the depth of flooding to the average surrounding grade. If the property is partially inundated by the SFHA and the street does not convey the flow, add the depth of flooding to the lowest lot elevation. Along with the information required for one of the abovementioned methods, provide sufficient certified topographic information, including flow paths, to show that the structure is located on high ground relative to the depth indicated on the NFIP map. If the request involves multiple properties (parcels of land or structures), elevations must be provided for each property. If the number of properties for which DHS-FEMA is to make a determination exceeds the number of rows on the Elevation Table, additional photocopies of the table may be attached to the back of the Elevation Form.

Certification (by a licensed land surveyor, registered professional engineer, or architect)

The certifier must provide his or her name, license number and expiration date, his or her company name, telephone number and, if applicable, his or her fax number and email address. The certifier's seal, if available, may be provided here. The certifier must sign and date the Elevation Form, where indicated, to certify the accuracy of the information provided. Not all states authorize architects and engineers to certify elevation information. Consult the state board of registration for more information.

Instructions:
In addition to the information provided, applicants need to upload the following documents for ALL LOMC requests:

OR

• Copy of the Property Deed (with recordation data and stamp of the Recorder's Office) AND Copy of the Tax Assessor's Map or other certified map showing the surveyed location of the property relative to local streets and watercourses. The recordation data (e.g., Book, Volume, Page, Reel, Document Number, and Date) must be evident on the copies of these documents so that DHS-FEMA can use the legal description of the property. In addition, DHS-FEMA must be able to identify the property exactly. If the property is not recorded on a Plat Map, a copy of a tax assessor's map or other suitable map must be submitted to aid DHS-FEMA in locating the property. The map should include at least one street intersection that is shown on the FIRM panel.

Endangered Species Act (ESA)

CLOMR-F applicants are responsible for documenting to FEMA that Endangered Species Act (ESA) compliance has been achieved prior to FEMA's review of a CLOMR-F application. ESA compliance may be documented by submitting to FEMA a copy of an Incidental Take Permit, an Incidental Take Statement, a "not likely to adversely affect" determination from the National Marine Fisheries Service (NMFS) or the U.S. Fish and Wildlife Service (USFWS), or an official letter from NMFS or USFWS concurring that the project has "No Effect" on proposed or listed species or designated critical habitat. The applicant may begin by contacting a NMFS or USFWS office, State wildlife agency office, or independent biologist to identify whether threatened or endangered species exist on the subject property and whether the project associated with the CLOMR-F request would adversely affect species or designated critical habitat. These entities are also available to discuss questions pertaining to listed species and ESA compliance. If potential adverse impacts could occur, then NMFS or USFWS may require changes to the proposed activity and/or mitigation.

For CLOMA, LOMA, and LOMR-F requests involving floodplain activities that have occurred already, private applicants and local and state jurisdictions are required to comply with the ESA independently of FEMA's process. These requests do not provide the same opportunity as CLOMR-Fs for FEMA to comment on the project because CLOMAs and LOMAs do not involve a physical modification to the floodplain and because LOMR-Fs are issued only after the physical action has been undertaken in the floodplain.

Revisions

Project Name/Identifier

The user must create a project name or designate an identifier that will help describe the project. This can be the name of a flood control project or other pertinent structure having an impact on the effective Flood Insurance Study (FIS) report, a subdivision or area, or some other identifying phrase. The Project Name/ Identifier may be up to 128 characters.

Revision Project Type

• Conditional Letter of Map Revision (CLOMR): A letter from FEMA commenting on whether a proposed project, if built as proposed, would justify a map revision, or proposed hydrology changes. The letter does not revise an effective National Flood Insurance Map (NFIP), it indicates whether the project, if built as proposed would be recognized by FEMA.
  
• Letter of Map Revision (LOMR): A letter from FEMA officially revising the current NFIP map to show the changes to floodplains, regulatory floodway or flood elevations. LOMRs 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).
  This Online LOMC application is not applicable for the following requests:

Select your community or communities of interest through the pull down menus. After selecting your community of interest, select the appropriate National Flood Insurance Program (NFIP) map panel(s), also known as a Flood Insurance Rate Map (FIRM) panel. The user has the option to select multiple NFIP panels, the same NFIP map panel, however may not be selected twice. If the NFIP map panel is listed under different community names, for example, the City of Smithfield and County of Smithfield, you may select both of these NFIP map panels.

A NFIP map panel is the official map of a community on which FEMA has delineated both the special hazard areas and the risk premium zones applicable to the community. If you need help finding your community, use the Map Service Center (MSC) website to find your community. Follow the steps below to guide you through this process:

Scanning Large Documents/Submission of Oversized Data Files
File packages less than 1 gigabyte (GB) in size can be uploaded. Any packages greater than 1 gigabyte (GB) in size or containing more than 8,000 files should be separated into multiple uploads or transferred to a CD, DVD, or Hard Drive and mailed to the LOMC Clearinghouse. Please ensure to include the Online LOMC Application ID and FEMA Case Number when sending oversized data files to the LOMC Clearinghouse.

Locate the NFIP map panel(s) you wish to revise and select the "Add" button. Use the "Remove" button to delete your selection. As a second option, you may also manually enter the map panel number and the effective date if you do not see your NFIP map panel. However, both "Map Panel Number" and "Other Map Number" cannot be selected at the same time.

If you are uploading multiple NFIP map panels, select all that are applicable to your revision request. You may select multiple map panels for your community, as long as the selected map panels are within your FEMA region. For example, you may not select a map panel in Connecticut and a map panel in Virginia. However, you may select a map panel in Virginia and Pennsylvania because they are within the same FEMA region. Below describes all FEMA regions and associated states:

NFIP Map Panel(s) not available for selected Community
Communities that do not have associated NFIP map panels are not eligible to submit the request through the Online LOMC web application. Please contact the FEMA Mapping and Information eXchange (FMIX) toll free at (877) 336-2627 (877-FEMA-MAP) for inquiries on availability of NFIP Map Panel(s) for the community of interest.

Flooding Source
A flooding source refers to a specific lake, stream, ocean, etc. This should match the flooding source name shown on the map panel, if it has been labeled. Examples of flooding sources include Lake Michigan, Duck Pond, or Big Hollow Creek.

Types of Flooding
After entering the appropriate flooding source, please select the type of flooding that affects the area of your revision request. Please select all that apply to your revision request:

• Riverine Flooding
• Coastal Flooding
• Shallow Flooding
• Alluvial Fan Flooding
• Lakes
• Other (Comments are required for this selection)

The basis of the request will determine what form(s) the requester will need to process the revision request. Below are descriptions for these types of revisions and basis for request:

• Alluvial Fan Analysis – Select this option if the revision request involves alluvial fans. The purpose of this form is to ensure that a structural flood control measure in areas subject to alluvial fan flooding is designed and/or constructed to provide protection from the 1% annual chance flood, in compliance with National Flood Insurance Program (NFIP) Regulation 44 CFR Ch. 1, Section 65.13, before it is recognized on an NFIP map. Elevating a parcel of land or a structure by fill or other means will not serve as a basis for removing areas subject to alluvial fan flooding from an area of special flood hazards. See NFIP Regulation 44 CFR Ch. 1, Section 65.13. Complete engineering analyses must be submitted in support of each section of this form. In addition, it may be necessary to complete other forms relating to specific flood control measures, such as levees/floodwalls, channelization, or dams.
  
• Base Map Changes – Select this option if the revision request includes updates to non-flood hazard data shown on the map such as transportation features. LOMRs may not be issued solely to reflect base map changes.
  
• Coastal Analysis – Select this option if the revision request is intended to document the steps taken by the requester in the process of preparing the revised models or analyses and the resulting revised Flood Insurance Study (FIS) information. Refer to the Consolidated Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix D: Guidance for Coastal Flooding Analyses and Mapping, which can be obtained from FEMA's website at https://www.fema.gov/media-library-data/1387816650819-3461f89a518dc03c0ef10165212a08b3/Guidelines_and_Specifications_for_Flood_Hazard_Mapping_Partners_Appendix_D-Guidance_for_Coastal_Flooding_Analyses_and_Mapping_(Apr_2003).pdf, for the wave height analyses and mapping procedures used by FEMA for coastal areas. Wave height, wave run-up, and storm-induced erosion may be analyzed using the program, CHAMP 2.0, which was developed for FEMA. CHAMP 2.0 may be obtained from FEMA's website at https://www.fema.gov/coastal-hazard-analysis-modeling-program-version-20. A list of accepted FEMA coastal models can be found on FEMA's website at https://www.fema.gov/coastal-numerical-models-meeting-minimum-requirement-national-flood-insurance-program.
  
• Corrections – Select this option if the Revision application displays an error on a previously issued LOMR and requires a correction to the NFIP map panel(s).
  
• Hydraulic or Hydrologic Analysis – Select this option if your revision request involves new or revised hydrologic and/or hydraulic analyses of rivers, streams, ponds, or small lakes. A separate form should be used for each flooding source.
  
• Improved Methodology/ Data – Select this option if you are utilizing a different technique (model) or have made adjustments to models used in the effective FIS. For revisions based on alternative methodologies or improved data, an explanation as to why the alternative methodology or improved data provides better results over the FIS must be presented and supported.
  
• Levee Certification – Select this option if your revision request involves a levee that is intended to show the area behind it with a reduced risk. A Levee certification is the process that deals specifically with the design and physical condition of the levee, and is the responsibility of the levee owner or community in charge of the levee's operations and maintenance. Certification must be completed for the levee to be eligible for accreditation by the Federal Emergency Management Agency (FEMA). Certification consists of documentation, signed and sealed by a registered Professional Engineer, as defined in Chapter 44 of the Code of Federal Regulations (44 CFR), Section 65.2. This documentation must state the following:
  
  • The levee meets the requirements of 44 CFR, Section 65.10
  • The data is accurate to the best of the certifier's knowledge
  • The analyses are performed correctly and in accordance with sound engineering practices

  This documentation is provided to FEMA to demonstrate that a registered Professional Engineer certified the levee, and meets the specific criteria and standards to provide risk reduction from at least the one-percent-annual-chance flood. Once the levee meets the other requirements of 44 CFR 65.10, FEMA can accredit the levee and show the area behind it as being a moderate-risk area on a Flood Insurance Rate Map (FIRM). If a community or levee owner wants the area behind a levee to be shown as reducing risk from the one-percent-annual-chance flood, they must first complete the process for having the levee certified.

  • Natural Changes– Select this option if the Revision application includes any natural changes, including erosion, subsidence, bridge/ culvert removal, etc. to the NFIP map panel(s).
    
  • New Topographic Data– Select this option if the Revision application involves any revised or improved topographic information to the NFIP map panel(s). New topographic data must be registered by a professional engineer or licensed surveyor.
    
  • Physical Change– Select this option if your request includes any man–made changes, watershed development, flood control structures, etc. Note that fees will be assessed for FEMA's review of proposed and "as-built" projects, as outlined in NFIP regulations 44 CFR Ch. 1, Part 72.
    
  • Regulatory Floodway Revision– Select this option if there is an effective regulatory floodway, or it is the community's intent to establish a regulatory floodway. 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 (100-year) flood without cumulatively increasing the water surface elevation more than a designated height. Please include an encroachment analysis of the base flood with your application.
    
  • Weir– Dam Changes–Select this option if the Revision application involves changes to the NFIP map panel(s) from weirs or dams.
    
  • Reissuance– Select this option if a previously issued LOMR was not incorporated into newly issued maps. LOMRs along flooding sources that have been restudied will usually not be able to be reissued.
    
  • Other– Select this option if the Revision application involves any basis for the request not included in the above items.
  Zone Designation

  Refer to the map panel(s) you previously selected when selecting the appropriate flood zone designation(s) affected. Below are descriptions of the FEMA flood zones:

  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.
  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.
  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.
  A1-A30	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).
  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.
  AE	The base floodplain where base flood elevations are provided. AE Zones are now used on new format FIRMs instead of A1-A30 Zones.
  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.
  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.
  V1-V30	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.
  VE	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.
  B	Area of moderate flood hazard, usually the area between the limits of the 100-year and 500-year floods. 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.
  C	Area of minimal flood hazard, usually depicted on FIRMs as above the 500-year flood level.
  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.
  X Shaded	Area of moderate flood hazard, usually the area between the limits of the 100-year and 500-year floods. 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.
  X Unshaded	Area of minimal flood hazard, usually depicted on FIRMs as above the 500-year flood level.
