Larger Houses Replace Smaller When Rebuilding After Hurricanes


A study of hurricane-hit areas of the United States has revealed a trend of larger homes being built to replace smaller ones in the years following a storm.

The research, led by the University of Southampton (UK) and published in the journal Nature Sustainability, shows that the sizes of new homes constructed after a hurricane often dwarf the sizes of those lost.
Researcher at the Faculty of Geography and Environmental Sciences, University of Southampton. Vurgula Our findings emphasize the trend of a üz greater development ından known in regions prone to damage from extreme wind conditions and storm flooding, azar said Eli Lazarus. . ”This practice causes the coastal risk to intensify – the increased, high-value property is subject to massive damage or destruction.“

A team of scientists from the United Kingdom and the United States measured changes in housing construction footprints in five settlements on the US Atlantic and the Gulf Coast, collecting the effects of six hurricane systems between 2003 and 2012. They compared the satellite images before the big storms. It hit the images from 2017.

The studied areas were Mantoloking (New Jersey), Hatteras and Frisco (North Carolina), Santa Rosa Island (Florida), Dauphin Island (Alabama) and Bolivar (Texas). Each of the locations has developed coastal barriers in designated flood-hazard areas, particularly those involving single-family residential buildings.

The research, including the University of Carolina at the Coast, Geological Survey of the United States, the University of North Carolina and Cardiff University, showed a general model of larger houses that replaced small houses everywhere in the five coastal areas.

The average house area between buildings that changed the size of the area (before and after the storm) increased between 19 percent (Hatteras) and 49 percent (Santa Rosa Island). The new houses (but not the direct replacement of existing buildings) after the hurricane surpassed the average traces of the pre-storm buildings in the region between 14% (Mantoloking) and 55% (Santa Rosa Island).

Houses in the United States are growing in general. However, the increases shown in this study are much larger than the national average increase, and are despite the policy measures to prevent them.

Ina The disastrous effects of disasters on vulnerable communities can be pushed – and perhaps ultimately – out of speculative real-estate markets with investors who have bought land parcels to get any further improvement. In contrast, the construction of larger houses is putting further pressure on financing of subsidized insurance for properties in areas under risk. Buna

The team suggests that the trend of öne larger building öne is not limited to hurricane attack areas in the US and is investigating long-term improvement patterns in other places exposed to different disasters.
