Detailed Integrated Tool to Estimate Potential Future Sea-Levels
For Consideration in Sandy Recovery — USACE SCENARIOS

Comparisons between USACE and NOAA Curves


This tool is intended to help the public understand, in a general way, some potential future vulnerabilities to changing sea levels, waves, tides, and surges in the New York and New Jersey areas. There are 2 basic steps:

Step 1: Obtain the base flood elevation (BFE) in your location using the FEMA BFE map below. BFE Information is available now for the following New Jersey Counties: Atlantic, Bergen, Burlington, Cape May, Essex, Hudson, Middlesex, Monmouth, Ocean, and Union. The BFEs are provided by FEMA to help communities better understand current flood risks and ensure structures are rebuilt stronger and safer to reduce the impact of similar events in the future.

Step 2: Enter the BFE into the sea-level rise calculator. The calculated table provides information for you to consider in preparing for potential future considerations.

For additional information, you can view the map provided by NOAA to see the sea-level scenarios, and compare to the USACE scenarios and USACE published guidance (pdf).
