CoreLogic Report Finds 6.9 Million Homes at Risk of Hurricane Storm Surge Damage with $1.6 Trillion in Potential Reconstruction Costs at Stake

Methodology

The analysis in the 2018 CoreLogic Storm Surge Report encompasses single-family residential structures less than four stories, including mobile homes, duplexes, manufactured homes and cabins (among other non-traditional home types). This is not an indication that there will be no damage to residential units greater than four stories, as there may be associated wind or debris damage. However, including all high-rise residential units in the analysis would inaccurately skew the actual number of houses at risk, as elevated structures are not as susceptible to damage from surge waters.

Year-over-year changes between the number of homes at risk and the RCV can be the result of several variables, including new home construction, improved public records, enhanced modeling techniques, fluctuation in labor, equipment and material costs – even a potential rise in sea level. For that reason, direct year-over-year comparisons should be warily considered. To estimate the value of property exposure of single-family residences, CoreLogic uses its RCV methodology which estimates the cost to rebuild the home in the event of a total loss and is not to be confused with property market values or new construction cost estimation. Reconstruction cost estimates more accurately reflect the actual cost of damage or destruction of residential buildings that would occur from hurricane-driven storm surge, since they include the cost of materials, equipment and labor needed to rebuild. These estimates also factor in geographical pricing differences (although actual land values are not included in the estimates). The values in this report are based on 100 percent (or “total”) destruction of the residential structure. Depending on the amount of surge water from a given storm, there may be less than 100 percent damage to the residence, which would result in a lower realized RCV.

To evaluate storm surge risk at the local level, CoreLogic uses the designation of Core-Based Statistical Areas (CBSAs), which are often referred to as metropolitan areas (>50,000 people), or micropolitan areas (<50,000 people), as defined by the U.S. Office of Management and Budget. The CBSA represents an urban center and the adjacent regions that are tied to that center socioeconomically. The specific areas identified in this report are named by primary urban center, though each may contain additional urban areas.

The high-resolution, granular modeling for underwriting individual risk allows enhanced understanding of the risk landscape and damage potentials. CoreLogic offers high-resolution solutions with a view of hazard and vulnerability consistent with the latest science for more realistic risk differentiation. The high-resolution storm surge modeling using 10m digital elevation model (DEM) and parcel-based geocoding precision from PxPoint™ facilitates a realistic view of the risk.
