Flood Insurance Rate Maps (FIRMs)

Federal Emergency Management Agency (FEMA) Region 2 and the New Jersey Department of Environmental Protection (DEP) hosted a virtual meeting on the Flood Insurance Study and Flood Insurance Rate Map update for 36 of the 39 jurisdictions in Morris County for Community Officials. They estimate the partial countywide flood maps will become effective in June 2022, following a Letter of Final Determination (LFD) in December 2021.

For additional information on the Partial Countywide Map adoption process see the FEMA fact sheet(PDF, 158KB)

Scientific Resolution Panel (SRP) municipalities maps are on a separate track than these 36 municipalities. FEMA is currently in the process of generating new flood maps for those three (3) municipalities (Lincoln Park, Montville and Pequannock). FEMA has a tentative date of the end of 2022 for release of preliminary firms (SRP Revised Preliminary Maps) for these municipalities.

The Federal Emergency Management Agency (FEMA) provides Flood Insurance Rate Maps (FIRM) which delineate special flood hazard areas and specific flood risk zones.  This information is used to determine:

  • flood insurance requirements
  • flood insurance rates
  • where local floodplain development regulations apply

FEMA has begun the process of updating Morris County FIRM by releasing preliminary FIRM and Flood Insurance Studies (FIS) in February 2016 and revised maps in August 2017. The adoption of these new maps will take 18-24 months.  Until these new preliminary FIRM are formally adopted, the existing FIRMs will be in effect as the basis of flood insurance premiums/rates and floodplain regulations.

FEMA is releasing the preliminary FIRM/FIS to provide local officials and property owners the opportunity for input early in the map adoption process.

This updated flood hazard information will help municipalities, residents and businesses plan for and reduce the risk from flooding in the future.  Start taking steps now to keep your communities and families safe from flood risk.

Know Your Risk

Understand the risk of flooding(PDF, 2MB)  in your area so that you will know how future floods may affect you and if specific flood insurance and building requirements apply to your property (or will apply in the future). View the preliminary FIRMs to find out your specific flood risk.

Know Your Role

Learn about your role in the map update process as a municipal official or as a property owner (homeowner, renter or business owner) and how you can reduce flood risk to your property and your community.

Take Action!

Use FEMA flood hazard data to make informed decisions to reduce your flood risk, such as rebuilding/recovery efforts or purchasing flood insurance.
