7.3 Million Homes at Risk of 2019 Hurricane Storm Surge Damage with $1.8 Trillion in Potential Reconstruction Costs, According to CoreLogic Report

IRVINE, Calif. — (BUSINESS WIRE) — May 30, 2019 — CoreLogic® (NYSE: CLGX), a leading global property information, analytics and data-enabled solutions provider, today released its 2019 CoreLogic Storm Surge report, which shows more than 7.3 million single- and multifamily homes along the Gulf and Atlantic Coasts have the potential for storm surge damage, with a total estimated reconstruction cost value (RCV) of nearly $1.8 trillion. Early predictions from the National Oceanic and Atmospheric Administration (NOAA) indicate a near-normal year for the 2019 Atlantic hurricane season.

The CoreLogic Storm Surge report provides an annual evaluation of the number of homes in the United States that are vulnerable to storm surge in the Gulf of Mexico and Atlantic Basin, which includes every state from Texas to Maine, approximately 3,700 miles. The report also includes associated RCV of these properties, which is calculated using the combined cost of construction materials as well as equipment and labor. The analysis examines risk across 19 states and 85 Core-Based Statistical Areas (CBSA). This is the first year the Storm Surge report analysis includes multifamily structures, which encompass apartments, condominiums and multi-unit dwellings.

“It is essential to understand and evaluate the total hazard exposure of properties at risk of storm surge prior to a hurricane event, so insurers can better protect and restore property owners from financial catastrophe,” said Dr. Tom Jeffery, senior hazard scientist at CoreLogic. “Damage from storm surge and inland flooding has proven to be far more destructive than wind in recent years, so we cannot rely on the hurricane category alone to give us a sense of the potential loss. A Category 5 hurricane in an area with few structures may be far less devastating than a Category 1 hurricane in a densely populated area.”

Regional Implications

State Implications

Metro Implications

CoreLogic looked at 85 Core-Based Statistical Areas (CBSA) to determine the metropolitan areas with the greatest number of homes exposed to and the highest RCV from storm surge flooding.

Important notes regarding definitions:

Single-family and multifamily homes are provided in separate charts and categorized by level of exposure to storm surge hazard from Categories 1 through 5 hurricanes. RCV figures represent the cost to completely rebuild a property in case of damage assuming the worst-case scenario at 100% destruction.

Note: These numbers are cumulative. A home being affected by a Category 1 storm would accordingly also be affected by a Category 5—so the highest Category represents the aggregate total.

Methodology

The analysis in the 2019 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). And, for the first time, the report also encompasses multifamily structures, which include apartments, condominiums and multi-unit dwellings. It is important to note that the inclusion of high-rise residential units such as those listed above may skew both the numbers associated with storm surge risk. This is because lower-level units are most likely to be affected, whereas the units above the second floor will rarely, if ever, experience storm surge flood damage.

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 and even a potential rise in sea level. Indeed, this year’s addition of new data in the form of multifamily structures has increased the total number of structures at risk. 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% 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). The CBSA represents an urban center and the adjacent regions that are socioeconomically tied to that center. 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.

The probabilistic CoreLogic North Atlantic Hurricane Model, which can be accessed in the catastrophe modeling platform RQE®, is powered with unparalleled property data from CoreLogic. The combination of high-quality data and detailed modeling provides realistic and credible view of the potential risk to make informed business decisions, understand risk and accelerate recovery.
