Study Finds Owners of Unprotected Coastal Homes Don’t Intend to Retrofit
New research from the University of Notre Dame shows that many coastal homes have significant structural vulnerabilities that leave homeowners and their homes largely unprotected from storms. Additionally, the majority of coastal homeowners have little to no intention of reducing these structural vulnerabilities, even though they live in areas frequently affected by damaging hurricanes and flooding.
According to the study, 62 percent of coastal homeowners are not considering taking any action to reduce the vulnerabilities of their homes or enhance protections against future hurricanes. Affordability had no statistically significant role in motivating homeowners in reducing their risk of structural damage.
“More often than not, a house is someone’s most valuable asset, yet only about half of coastal homeowners — who are familiar with the risk and cost of hurricane damage — had windows that could withstand the impact of airborne debris and only about a third had entry doors with this level of protection,” said Debra Javeline, associate professor of political science at Notre Dame and co-lead on the study. “Coastal homeowners may assume building codes and insurance absolve them from the responsibility for reducing risk to future storms, but unfortunately that lack of responsibility is often paid for through post-disaster recovery efforts, which are shown to cost four to 10 times more than preventative measures.”
Published in Climatic Change, the study analyzed a survey of 662 residents in one of the most frequently exposed coastal communities in the United States, North Carolina’s New Hanover County. One year after the survey was taken, Hurricane Florence hit the survey area and led to an estimated $24 billion in total damages, according to the National Oceanic and Atmospheric Administration’s National Climatic Data Center.
In the survey, coastal homeowners were asked about structural mitigations they had either implemented or intended to implement. Additionally, the survey posed questions about hurricane and flood experiences, home valuation, insurance experiences, socio-political attitudes, and opinions.
Notre Dame researchers found that nearly half of survey respondents weren’t aware of their door’s impact rating, which defines how well it can withstand the impact of airborne debris. About a third also answered “don’t know” to questions about the impact ratings of their windows and garages. Overall, 60 percent of those surveyed had neither protective cover nor impact ratings on their entry doors. The researchers said this suggests that coastal homeowners take only minimal actions to reduce their risk of likely hurricane or flood damage.
