FEMA Flood Insurance Rate Maps (DFIRM) Update
Howard County Government’s Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Information Service
Flood Insurance Rate Map (FIRM) Information
As a public service, Howard County Government provides residents with floodplain information upon request based on the Federal Emergency Management Agency’s (FEMA’s) effective Flood Insurance Rate Map (FIRM). Visit the County’s Digital Flood Insurance Rate Map website to view mapping and information on:
- Flood zone and base flood elevation and depth
- Location and elevation of a property or building structure relative to the Special Flood Hazard Area (SFHA)
- Information on historic FIRMs
- Information on County-regulated floodplains
Paper FIRMs are also available for viewing at the Stormwater Management Office located at 6751 Columbia Gateway Drive, Suite 514, Columbia, MD 21046.
Current Elevation Certificates in the County can be found here.
Flood Insurance Information
If a building is within a Special Flood Hazard Area (SFHA), a lender is required by law to require a loan recipient to purchase a flood insurance policy on the building. Therefore, if your building is in a SFHA and you have a mortgage loan from a federally related financial assistance program or from a lender that is regulated, supervised, or insured by federal agencies, you would be required to purchase flood insurance. SFHAs are considered to be high risk Flood Zones A and AE. Federal law does not require flood insurance purchases in moderate risk Shaded Zone X or low risk Flood Zone X areas, however, lenders and/or insurance agents could still require you to purchase flood insurance based on their own risk assessment and judgment. If your building or property is outside of FEMA’s SFHA or outside of the County-regulated 100-year floodplain, you still have the option to purchase flood insurance if you feel it is warranted. If you have additional questions related to flood insurance, contact your homeowner’s insurance agent or consult the National Flood Insurance Program (NFIP) at www.floodsmart.gov or 1-888-379-9531.
County Floodplain Development Restrictions
Your property may be located within the County-regulated 100-year floodplain delineated for smaller drainage areas than those delineated by FEMA for its SFHA. If this is the case, County development restrictions would apply to your property. For additional information on County development regulations related to the 100‑year floodplain please contact the Department of Planning and Zoning at 410-313-2350.
FEMA Digital Flood Insurance Rate Maps (DFIRM) Update - Effective November 6, 2013
In November 2013, the Federal Emergency Management Agency (FEMA) made effective new Flood Insurance Rate Maps (FIRM) for Howard County, which replaced the 1986 FIRMs. FIRMs are used by the National Flood Insurance Program (NFIP) to determine if flood insurance is mandatory on any given property and now the 2013 FIRMs more accurately represent flooding risks change over time due to changes in land use, weather events and other factors. The 2013 FIRMs were then digitized and are referred to as Digital Flood Insurance Rate Maps (DFIRM). Note that the 2013 FIRM and DFIRM have the same information; the DFIRM is simply the 2013 FIRM in digital format.
How will these changes affect me?
As a result of changes in the DFIRM:
1) Some homes will be included in the Special Flood Hazard Area (SFHA), i.e., the FEMA regulated 100-year flood plain for the first time
- If your home is in the floodplain (SFHA zones “A” or “AE”) based on the new maps and you have a mortgage from a federally-regulated lender you will, most likely, be required to carry flood insurance after the new maps go into effect.
2) Some homes will be removed from the mapped floodplain (SFHA)
- If your home is currently in the FEMA floodplain but, under the new DFIRM, has been taken out of the floodplain, flood insurance will no longer be required by FEMA.
- However, if another part of your property other than your home remains in the floodplain, your mortgage holder may still elect to require you to carry flood insurance.
- You may, at your own discretion, maintain flood insurance, but at the lower rates offered to homes outside the SFHA.
3) Some homes will remain in the mapped floodplain (SFHA)
- If your home was in the previous flood plain, and is also shown on the new map or DFIRM as still in the floodplain (SFHA, zone “A” or “AE”), and has a mortgage from a federally-regulated lender, then by federal law your lender must require you to carry flood insurance.
Regardless of the FEMA flood designation for your home, if you feel your home is at risk of flooding, you may still purchase flood insurance.
