Sea Level Rise Planning Tool - New Jersey and New York State
NOAA, in partnership with FEMA, USACE, USGCRP, and CEQ has created a set of map services and related tools to help communities, residents, and other stakeholders consider risks from future sea level rise in planning for reconstruction following Hurricane Sandy. Even if current storm patterns remain the same in the future, sea level rise will increase the impact of coastal flooding during storms. We have resources that help us quantify current risk, such as FEMA’s Most Recent Flood Hazard Data for affected areas of New York and New Jersey, but these do not provide information on future risks.
The map services provided here integrate FEMA's most recent special flood hazard area (SFHA) with four scenarios of sea level rise (referred to as lowest, intermediate-low, intermediate-high, and highest). These scenarios provide estimates of global sea level rise by the year 2050 and 2100 based on the best available science synthesized by a panel of scientists from multiple federal agencies and academic institutions to provide to the U.S. National Climate Assessment. A detailed explanation of the scenarios is published in an interagency report titled “Global Sea Level Rise Scenarios for the United States National Climate Assessment” (Parris et al, 2012). These four scenarios address different factors known to affect future sea level rise risk, including ocean warming and melting of mountain glaciers and ice sheets.
