New York City’s June 2015 appeal letter to FEMA spells out the consequences due to overestimating errors in the FEMA mapping: “First, homeowners in the who invest in their homes could end up building or rebuilding to excessive heights at extra cost, with additional impacts on neighborhood character. According to the study, the last storm surge comparable to Sandy occurred prior to the year 1700. The study was based on an analysis of past storms dating back to the 1700s. Alan Blumberg from Stevens Institute of Technology and four other scientists entitled A Validated Tropical-Extratropical Flood Hazard Assessment for New York Harbor concluded that Sandy was a 260-year storm. Yet, a January 2016 study conducted by Dr. The FEMA flood maps are supposed to represent a 100-year floodplain. Following the agreement, Mayor de Blasio stated, “Our City needs precise flood maps that reflect real risks, both today and years from now–and we have to do that fairly.” On October 17, 2016, New York City Mayor Bill de Blasio and FEMA announced an agreement to revise New York City’s flood hazard maps, dramatically reducing the number of people and properties in FEMA’s flood zone. This past year, the City of New York successfully challenged its flood hazard maps contending that FEMA’s analysis contained significant technical and scientific errors, overstating the Base Flood Elevations by more than two feet in many areas of the City and unnecessarily expanding the flood hazard area by 35 percent. Several years earlier, FEMA set advisory standards for the new maps for the first time since 1983. ![]() The new boundaries are based on a coastal flood study conducted by FEMA Region II for portions of coastal New York and New Jersey. For homeowners already saddled with mortgages, high taxes and other costs, their homes may no longer be affordable.įEMA’s flood zone boundaries are for a 100-year storm meaning that there is a one percent chance of experiencing a flood in a given year. If the federal government ends subsidies to the National Flood Insurance Program, as they have been threatening to do, rates could skyrocket. Flood insurance rates have been climbing steadily. Any mortgaged properties in these zones will be required to carry flood insurance.īy 2014, the National Flood Insurance Program had incurred $24 billion in debt as a result of Hurricanes Katrina, Rita and Sandy. About 80 percent of Hoboken will be on these expanded flood maps. That will put most of the 600 Garden Street block squarely within FEMA’s flood hazard zone. The Federal Emergency Management Agency (FEMA) revised flood maps, which are now preliminary, will go into effect in several years. The ground became saturated with water which seeped into their basement to a depth of several inches. Her next door neighbors, Aaron Lewit and Lynne Shapiro experienced minor flooding during Sandy. When Superstorm Sandy hit in October 2012, the street at the 600 block of Garden was dry. She says the neighborhood has never flooded. She has lived on that block since 1957, nearly 60 years. ![]() For more information on using the data in Google Earth™, please see Using the National Flood Hazard Layer Web Map Service (WMS) in Google Earth™.Joan Golizio, age 81, lives at 625 Garden Street in Hoboken. To do so, you will need GIS or mapping software that can read data in shapefile format.įEMA also offers a download of a KMZ (keyhole markup file zipped) file, which overlays the data in Google Earth™. This data can be used in most GIS applications to perform spatial analyses and for integration into custom maps and reports. Using the “Search All Products” on the MSC, you can download the NFHL data for a County or State in a GIS file format. You can also use the address search on the FEMA Flood Map Service Center (MSC) to view the NFHL data or download a FIRMette. For more information on available services, go to the NFHL GIS Services User Guide. Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications. In the NFHL Viewer, you can use the address search or map navigation to locate an area of interest and the NFHL Print Tool to download and print a full Flood Insurance Rate Map (FIRM) or FIRMette (a smaller, printable version of a FIRM) where modernized data exists. Or you you may view, download, and print current local digital effective flood hazard data in an ArcGIS map.
