SAN DIEGO, CA – HazardHub, the nation’s most comprehensive provider of hazard risk data, is proud to release HazardHub FloodTM, a new and powerful assessor of a property’s overall flood risk.
In the United States, flood assessment is usually left to the Federal Emergency Management Authority (FEMA). While FEMA’s in/out assessments of flood zones are important, they can also be limiting due to aged flood maps, political considerations and communities simply not participating in FEMA’s Flood zone analysis. HazardHub Flood overcomes these issues by combining reams of highly granular data to provide an overall risk of flood regardless of a property’s FEMA Flood Zone rating.
HazardHub combines four critical elements in creating HazardHub Flood – source of potential flooding (river, pond, stream), elevation difference between the property and the potential source, and the distance to those sources. Also – if the property is near a shoreline – the flood model will alert the risk of storm surge. The result is an unparalleled view of the likelihood of a property “getting wet” due to external water.
Brady Foust, Chief Science Officer for HazardHub explains that “For too long there has been an over-reliance of FEMA flood maps in determining a property’s risk of flood. As we saw with Hurricane Harvey and other major flood events throughout the country, hundreds of properties that were marked as low likelihood of flood by FEMA actually ended up flooded. Many of these same properties showed very high risk of a flood with HazardHub Flood.”
In a recent client analysis, HazardHub Flood identified that 17% of properties identified by FEMA as “low risk of flood” were actually at a very high risk of flood due to their proximity to water. Conversely, 14% of properties inside of 100-year flood zones were actually far enough above nearby water to determine that they had a limited risk from flood.
In the 2010 Nashville Flood, there were approximately 11,743 locations inside of the flood perimeter. FEMA classified 5,184 properties as either 100 or 500-year flood zones (44%), while the HazardHub Flood Model found an additional 3,076 properties at high or very high risk of flood.
Bob Frady, CEO of HazardHub adds, “We at HazardHub want to take the politics out of flood zone determinations and simply look at what the data and science tell us. HazardHub Flood measures flood risk both inside and outside of FEMA flood zones, providing a clear and unbiased determination of a property’s overall flood risk. HazardHub flood is the culmination of thousands of hours of effort and hundreds of gigabytes of data. We’re very excited to launch HazardHub Flood and prove its value to the flood risk market.”
HazardHub Flood is available immediately via the HazardHub API or – for the analysis of very large files – via batch from HazardHub. To learn more, contact HazardHub.com/contact.
