![]() ![]() Hurricane Sandy's impact was the first time in recent memory, and record, that coastal water levels had reached the heights they attained in many places in the state of New York. This program allows for an assessment of building loss on a block-by-block level. The HAZUS program is used to estimate potential loss from disasters such as earthquakes, wind, hurricanes, and floods. ![]() The researchers came up with the estimates by using census data and FEMA's HAZUS modeling software program. Inset shows enlargement of the five counties that comprise New York City-Bronx, Kings, New York, Queens, and Richmond. Locations of permanent and temporary monitoring sites and high-water-mark sites that documented the storm tide of Hurricane Sandy in New York counties. The results can also assist with resiliency planning that helps communities prepare for future storms. "The results from this new study demonstrated how the additional resolution and accuracy of flood depictions resulting from these efforts greatly improved the damage estimates."ĭamage estimates can be used by FEMA and other stakeholders to help prioritize relief and reconstruction efforts following a storm. "FEMA funded the sensor placement we did prior to the storm and our assessment of how high the water reached after the storm," Schubert said. The USGS researcher called the study a "proof of concept" that really showcased the value of gathering storm data before and after a storm. ![]() "What we found was that the biggest jump in estimate reliability comes between the initial estimate and the two-week mark, but that the additional information available three months after an event greatly helps refine the estimates even further." We looked at how estimates of building damage change depending on the amount of information available at the time of the estimate, looking at three time periods-storm landfall, two weeks later, and then three months later," said Chris Schubert, a USGS hydrologist and lead author of the study. The study, " Analysis of storm-tide impacts from Hurricane Sandy in New York," prepared in cooperation with the Federal Emergency Management Agency (FEMA), marks the first time the agency has done this type of analysis and cost estimation for a coastal storm. Location of study area in New York and tracks of Hurricane Sandy, Tropical Storm Irene, and the storm of December 11–13, 1992, in the North Atlantic region. ![]()
