Updated Flood Insurance Rate Maps
for Cambridge & Middlesex County

Webpage updated 12/17/2009

FEMA issues letter of final floodplain determination for Cambridge and Middlesex County

A letter of final determination (LFD) was issued by FEMA on December 4, 2009 notifying the City of Cambridge that final flood elevations for the City have been determined. Final Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) will be issued shortly. These documents will be consistent with the report and plans previously provided by FEMA and are available on this web page.

The final FIRMs becomes effective on June 4, 2010. Property owners with a federally backed mortgages within the revised floodplain area will be required to obtain flood insurance through the National Flood Insurance Program. It is recommended that property owner's speak to their insurance agents and obtain flood insurance prior to the effective date of the revised FIRMs to take advantage of any potential grandfathering of flood insurance rates. For more information contact FEMA's insurance Specialist, Daisy Sweeny at 617.832.4788 or daisy.sweeney@dhs.gov.

Important Information

If you purchase flood insurance before the effective date, you may benefit from the lower-cost “grandfathering” insurance option. Please note that in order for your insurance to be active by the effective date of the new maps, the insurance should be purchased at least 30-days in advance of the effective date. You should check with your insurance agent for details. Please continue to refer back to this page for any updates and schedule changes.

What You Should Know

The Federal Emergency Management Agency (FEMA) has recently completed a study which re-examined Middlesex County flood zones and has developed preliminary revised detailed, digital flood hazard maps for the Alewife area in the City of Cambridge. The proposed new maps -- also known as Flood Insurance Rate Maps (FIRMs) -- reflect current flood risks, replacing maps that are over 25 years old. The reason these maps are produced is to provide home owners, mortgage companies, insurance companies and agents and other interested parties information specific to flood risk in areas adjacent to or impacted by local rivers which are subject to flooding. Maps can be viewed on-line, see the links below under Additional Information or at local branch libraries and the following municipal offices: City Clerk, Conservation Commission, Community Development, Inspectional Services and Public Works.

How will these changes affect you?

Some parcels in the Alewife area have been mapped into a higher risk zone, known as a Special Flood Hazard Area (SFHA), and shown on the FIRM as “AE”, and other parcels have been mapped into a lower risk zone, shown on the FIRM as “X”. The SFHA is the area that will be inundated by the flood event having a 1% chance of being equaled or exceeded in any given year. The Zone X area is the area that will be inundated by the flood event having a 0.2% chance of being equaled or exceeded in any given year.
Parcels in a SFHA: If you have a mortgage from a federally-regulated lender and the building(s) on this parcel are within the SFHA, then by federal law, your lender must require you to carry flood insurance when these flood maps become effective. Flood insurance is available through the National Flood Insurance Program (NFIP), a federally underwritten program provided by nearly 100 insurance companies and written through licensed insurance agents. Contact your insurance agent to learn about lower-cost “grandfathering” options offered by the NFIP for properties being mapped into higher-risk areas for the first time. If you do not have a mortgage, FEMA still recommends that you purchase flood insurance, but you are not obliged to do so. Most homeowners’ insurance policies do not provide coverage for damage due to flooding. For more information on flood insurance, visit the National Flood Insurance Program’s website, www.floodsmart.gov *.
Parcels in Zone X: While flood insurance in these areas is optional, maintaining coverage is recommended by FEMA as the flood risk has only been reduced, not removed. Lower cost flood insurance from the National Flood Insurance Program (NFIP) is available in low- to moderate-risk areas and you may also qualify for the even lower cost Preferred Risk Policy (PRP). Contact your insurance agent to learn more about how to convert to the PRP. For more information on flood insurance, visit www.floodsmart.gov *.


If you feel there has been an error, you can file a Letter of Map Amendment (LOMA)


If you were unable to file an appeal or protest and believe that your property has been included in the Special Flood Hazard Area (SFHA) in error, then FEMA has established administrative procedures to change the designation for these properties on the effective FIRM. These processes are referred to as the Letter of Map Amendment, or LOMA, process and the Letter of Map Revision Based on Fill, or LOMR-F, process. Through these processes, an individual who owns, rents, or leases property may submit certain mapping and survey information to FEMA and request that FEMA issue a document that officially removes a property and/or structure from the SFHA. In most cases, the applicant will need to hire a Licensed Land Surveyor or Registered Professional Engineer to prepare an Elevation Certificate for the property. Upon receiving a complete application forms package, FEMA will normally complete its review and issue its determination in 4 to 6 weeks. Guidance information and determination requirements can be found at: http://www.fema.gov/plan/prevent/fhm/fmc_loma.shtm or you can call the FEMA Map Assistance Center at 1-877-336-2627.
