FEMA—Flood Plain Management Information

The City of Mission Viejo participates in the National Flood Insurance Program (NFIP), which is administered by the Federal Emergency Management Agency (FEMA).  This is a voluntary program in which the City is required to follow a rigorous certification process and must enforce and maintain minimum flood plain management standards in order to maintain eligibility.  For example, the City has to ensure that projects within or fringing on a floodway or floodplain comply with FEMA regulations and requirements. Lenders, appraisers, insurance companies, realtors, and property owners are interested in the flood zone or Special Flood Hazard Area, which is reflected on Flood Insurance Rate Maps published by FEMA and is normally used to evaluate construction, lending and insurance requirements.

Since the City has been certified by the NFIP, homeowners, renters, and businesses are eligible to purchase flood insurance.  In addition, the City has gone through additional certification measures, which entitle anyone who purchases flood insurance within the City to a discount on their premium.

Flood Zone Information

Flood Insurance Rate Maps

The Flood Insurance Rate Map (FIRM) is the official flood map of a community on which FEMA has delineated both the special hazard areas and the risk premium zones applicable to the community.  Each FIRM has a unique identifier and a designated effective date. The effective date is the date on which the FIRM enters into force as the official regulatory flood map for the area it covers. 

To access the Flood Insurance Rate Maps in digital format, please visit FEMA's Map Service Center.  To locate the correct FIRM for your property location, follow these instructions:

  1. In the Search box enter your property address (including city and state) and click on "Search".
  2. When the map appears, select the View button.  The map will pop up in a new window.
  3. Click on the buttons in the left column to manipulate the map.  For example, clicking on the "MAX Zoom Out" button expands the map to fill the screen window.

Information regarding the flood zone designation for properties in the City of Mission Viejo may also be obtained by using the City's GIS system and entering a specific property address or APN number. To obtain your property's information, click on "View" and in the drop-down menu click on "FIRM Panel". Click on the FIRM Panel Number once it appears on the map for the FIRM ID and effective date.

What is a FIRMette?

Full FIRM panels are quite large (36' x 25.875'), so most users will prefer to create and print out a smaller selected portion. After finding your specific area of interest, such as your house or development, you can create a FIRMette of the area. A FIRMette is a full-scale section of a FIRM that you create yourself and that is formatted to fit on standard printer paper sizes. FIRMettes can be used to make determinations under the National Flood Insurance Program.

Moving Around in FIRMette Web

You can navigate around the image of the map and use the labeled streets or other map features to locate your specific area of interest. Select the Zoom In or Zoom Out buttons to zoom in or out on the image when you click the cursor on the map. Use the Pan button to move around within the map when you click the cursor.

Making a FIRMette

Once you have chosen the tab to Make a FIRMette, FIRMette Web loads a set of new printing functionalities, located at the bottom of the toolbar area, and three translucent boxes in the main map window.  The printing functionalities allow you to specify aspects of the FIRMette output such as page size and file format, and the translucent boxes allow you to specify the print area. There are four basic steps for making a FIRMette:

  • Select a page size.

There are three standard page sizes, and the default is letter size. You can adjust the page size by selecting the corresponding button. Notice that the size of the translucent box located at the upper left corner of the map changes with the page size, i.e., the larger the page size, the bigger the area of the box and vice versa.

  • Confirm the special print area.    

There are three translucent boxes in the main map window. Their function is to help the user to define the printing area of the map, the scale and north arrow, and the FIRMette title block. You can define the area by dragging the active box over to the area of interest (e.g., near your property location). An active box is represented by the red translucent box with the green border, and only one box is active at a time. Switching between the active boxes can be done by clicking on the corresponding buttons.

  • Select a save format.

A FIRMette can be created in either .pdf or .tif format. After clicking the corresponding button, a preview page is generated which allows you to see how the FIRMette will look.

  • Save the FIRMette. 

By selecting the Save your FIRMette button, a download prompt opens.  Depending on your internet browser and settings, you may be asked to select a preferred option (e.g., Save, Save As, etc.) to download the FIRMette to your computer in your chosen file format.  Otherwise, the download will begin automatically.

Flood Insurance Rate Map and National Flood Insurance Program information is also available at the City's Engineering Counter and Mission Viejo Library.  Private companies offer flood zone determinations based upon the current Flood Insurance Rate Map information.  For floodplain questions other than specific zone determinations, please check out the Frequently Asked Questions page for additional information.

FEMA Forms

Flood Mapping-Related Forms

The table below provides descriptive information about various FEMA flood map-related forms and how to download. This page is intended for the general public, industry professionals and government officials interested in submitting a Letter of Map Change (LOMC) request via mail and/or obtaining other flood hazard mapping-related data for engineering, surveying or construction purposes.

For questions about FIRMs, LOMAs, flood mapping procedures, or the map revision process, call 1-877-336-2627 toll-free and ask to speak with a “FEMA Flood Map Specialist” or visit the FEMA website to download flood mapping-related forms.

Form Form Description
Elevation Certificate

The National Flood Insurance Program (NFIP) Elevation Certificate (EC) (FEMA form 086-0-33) is an administrative tool of the NFIP, which is to be used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, or to support a request for a Letter of Map Amendment (LOMA) or a Letter of Map Amendment based on fill (LOMR-F).

The Elevation Certificate is required to properly rate post-FIRM buildings, which are buildings constructed after publication of the FIRM located in flood insurance Zones A1-A30, AE, AH, A (with Base [1 percent annual chance] Flood Elevation [BFE]), VE, V1-V30, V (with BFE), AR, AR/A, AR/AE, AR/A1-A30, AR/AH and AR/AO. The Elevation Certificate is not required for pre-FIRM buildings unless the building is being rated under the optional post-FIRM flood insurance rules.

Floodproofing Certificate 

The National Flood Insurance Program (NFIP) Floodproofing Certificate (FEMA form 086-0-34) is the form to be used to certify a floodproofing design for non-residential buildings that are permitted as an alternative to elevating to or above the Base Flood Elevation (BFE).

MT-EZ Form

Application Form for Single Residential Lot or Structure Amendments to National Flood Insurance Program Maps
(Condensed Version of the MT-1 Form)

This form should be used to request that FEMA remove a single structure or a legally recorded parcel of land or portions thereof, described by metes and bounds certified by a Registered Professional Engineer or Licensed Land Surveyor, from a designated Special Flood Hazard Area (SFHA), an area that would be inundated by the flood having a 1 percent annual chance of being equaled or exceeded in any given year (base flood), via a Letter of Map Amendment (LOMA). A LOMA is a letter from FEMA stating that an existing structure or parcel of land that has not been elevated by fill (i.e., the existing structure or parcel of land is on natural grade) would not be inundated by the base flood. Fill is defined as material placed to raise the ground to or above the Base Flood Elevation.

MT-1 Form

Application Forms for Conditional and Final Letters of Map Amendment and Letters of Map Revision Based on Fill
(For all LOMA, CLOMA, LOMR-F, and CLOMR-F Requests)

This form should be used to assist requesters (community officials, individual property owners, and others) in gathering the information that FEMA needs to determine whether property [i.e., structure(s), parcel(s) of land] is likely to be flooded during the flood event that has a 1-percent chance of being equaled or exceeded in any given year (base or 100-year flood).  The area flooded by the 1-percent-annual-chance flood is called the Special Flood Hazard Area (SFHA). The mandatory flood insurance purchase requirements of the National Flood Insurance Program (NFIP) apply to insurable structures in the SFHA shown on an effective NFIP map.

The forms in this package should be used to request that FEMA remove structures or legally recorded parcels of land or portions thereof, described by metes and bounds certified by a Registered Professional Engineer or a Licensed Land Surveyor, from a designated Special Flood Hazard Area (SFHA) via Letter of Map Amendment (LOMA) or Letter of Map Revision Based on Fill (LOMR-F). These forms are also used for requesting FEMA’s comments on a proposed project issued in the form of a Conditional Letter of Map Amendment (CLOMA) or Conditional Letter of Map Revision Based on Fill.

MT-2 Form

Application Forms for Conditional Letters of Map Revision and Letters of Map Revision
(For all LOMR, CLOMR and PMR Requests)

This form should be used for revisions to effective FIS reports, FIRMs, or FBFMs by individual and community requesters. These forms will provide FEMA with assurance that all pertinent data relating to the revision are included in the submittal. They also will ensure that: (a) the data and methodology are based on current conditions; (b) qualified professionals have assembled data and performed all necessary computations, and (c) all individuals and organizations affected by proposed changes are aware of the changes and will have an opportunity to comment on them.

Standard Flood Hazard Determination Form The current Standard Flood Hazard Determination Form (SFHDF) (expiration date December 31, 2011) remains valid until a new SFHDF has been approved.  Please periodically check the link for updates to the form.

The Standard Flood Hazard Determination Form (SFHDF) is required for all federally-backed loans and is used by lenders to determine the flood risk for their building loans. The SFHDF is authorized by the National Flood Insurance Reform Act of 1994 (NFIRA) and is imposed on lenders by their regulatory entities, not by FEMA.  FEMA oversees the National Flood Insurance Program (NFIP), which makes federally-administered flood insurance available throughout the United States and is responsible for development, updates and making the form available to users.

Implementation of the mandatory flood insurance purchase requirements of the Flood Disaster Protection Act of 1973 and the National Flood Insurance Reform Act of 94, as amended, is the responsibility of the various Federal agencies that regulate lenders. Please contact your regulator or lender to determine their requirements. 
External Data Request (EDR) for the FEMA Engineering Library

Most FEMA Engineering Library requests should be made though the Engineering Library's External Data Request (EDR) process. Use this form to submit an EDR request to the FEMA Engineering Library. For more information on the FEMA Engineering Library, visit the FEMA Engineering Library webpage.

National Flood Insurance Program (NFIP)

The NFIP is a Federal program created by Congress to mitigate future flood losses nationwide through sound, community-enforced building and zoning ordinances and to provide access to affordable, federally backed flood insurance protection for property owners. The NFIP is designed to provide an insurance alternative to disaster assistance to meet the escalating costs of repairing damage to buildings and their contents caused by floods.

Participation in the NFIP is based on an agreement between local communities and the Federal Government that states that if a community will adopt and enforce a floodplain management ordinance to reduce future flood risks to new construction in Special Flood Hazard Areas (SFHAs), the Federal Government will make flood insurance available within the community as a financial protection against flood losses.

In support of the NFIP, FEMA identifies flood hazard areas throughout the United States and its territories. Most areas of flood hazard are commonly identified on Flood Insurance Rate Maps (FIRMs).  The FIRM is an official map of a community on which FEMA has delineated both the special hazard areas and the risk premium zones applicable to the community.  One of these areas is the Special Flood Hazard Area (SFHA). The SFHA is a high-risk area defined as any land that would be inundated by a flood having a 1-percent chance of occurring in a given year (also referred to as the base flood).

A Letter of Map Amendment (LOMA) is a letter that officially revises an effective FEMA NFIP map. A LOMA results from an administrative procedure involving the review of scientific or technical data submitted by the owner or lessee of property who believes the property has incorrectly been included in a designated SFHA or has been incorrectly identified in the wrong SFHA.  A LOMA amends the currently effective FEMA map and establishes that a specific property is not located in the SFHA or is located within the correct SFHA.

Letters of Map Revision (LOMR)/Letters of Map Amendment (LOMA)

If you believe your property was incorrectly included in a National Flood Insurance Program (NFIP) identified Special Flood Hazard Area (SFHA), you may submit an application to FEMA for a formal determination of the property's location and/or elevation relative to the SFHA.  The SFHA is the area that has a 1 percent or greater chance of flooding in any given year; this area is also referred to by some as the 1-percent-annual-chance floodplain, base floodplain, or the 100-year floodplain.  After FEMA reviews the map change request, it will issue a Determination Document, either approving or denying the map change.  If FEMA grants the map amendment or revision request, you may no longer be required to purchase flood insurance.  You may send the Determination Document to your mortgage lender and request that the federal flood insurance requirement for the structure be removed.
