As communities begin to recover from the devastating effects of Hurricane Sandy, it is important to recognize lessons being learned and to employ mitigation actions that ensure structures are rebuilt stronger, safer, and less vulnerable to future flooding events.

Rebuild Safer and Stronger
If your home or business has been flooded, you can utilize many of FEMA’s resources to better understand how to rebuild safer and stronger.  It is important to contact your local community to understand what you need to know before rebuilding.  Given the level of flood risk you face, there are resources to understand the proper construction techniques that should be used for protecting your home or business.  

Hurricane Sandy Road to Recovery:  A New York Homeowner's Guide is a FEMA publication available to inform homeowners affected by Sandy of different options and resources available for recovery.

The FEMA publication Mitigation Ideas:  A Resource for Reducing Risk from Natural Hazards is available to help communities identify and evaluate potential mitigation actions for reducing risk from natural hazards and disasters. You can also learn about best practices that have been implemented by other communities through FEMA’s Mitigation Best Practices search webpage or view FEMA’s catalog of mitigation fact sheets.

Flood Insurance
Be prepared for the next flood by looking into a flood insurance policy.  Visit to find information on the National Flood Insurance Program (NFIP) and to find an insurance agent near you.

For local communities, there is a significant opportunity to help save lives, prevent property damage, and reduce the cost of flood insurance for your residents by joining FEMA’s Community Rating System (CRS).  CRS recognizes community efforts beyond the minimum standards for floodplain management by reducing flood insurance premiums for the community’s property owners.

Resources Available to Help an Individual Take Action
Learn about Increased Cost of Compliance Coverage that may be available to help some property owners reduce the risk of damage from future floods by elevating, flood proofing, demolishing, or relocating their building to meet the requirements of a local community’s building ordinances. 

Learn more about FEMA’s hazard mitigation assistance programs which are available to local governments and communities to provide funding for eligible mitigation activities that reduce disaster losses and protect life and property from future disaster damages.

Property and business owners should also work with their local communities to determine if there are other programs and resources available to support elevating your home or business.
