The 2019 storm surge report

The 2019 CoreLogic® Storm Surge Report provides an annual evaluation of the number of single-family and, new this year, multifamily residential homes in the United States that are vulnerable to storm surge in the Gulf of Mexico and Atlantic Basin. All numbers discussed in the body of the report comprise both single-family and multifamily homes in aggregate unless specified otherwise. The report also includes the associated reconstruction cost value (RCV) of these properties. This year’s analysis shows which areas along each region’s coasts are susceptible to this type of flooding event. The risk of storm-surge flooding is not uniform along either coast, nor is risk limited to states with a reputation for more frequent hurricane activity such as Florida or Louisiana. Every state with a coastline that borders the Gulf of Mexico or the Atlantic Ocean has areas of high risk for storm surge damage. 

The 2019 CoreLogic Storm Surge Report provides the following data and analysis:

1. The number of homes, both single family residences (SFR) and multifamily residences (MFR), at risk of storm-surge flooding by state and core-based statistical area (CBSA)
2. The RCV for the associated at-risk homes
3. The probabilistic loss analysis of 2018 storm surge events
4. A pre-season forecast for 2019

This analysis covers the 19 states which border the Gulf and Atlantic coasts. It does not include storms that occur within the Pacific basin. This is because storm surge damage along the coasts of Hawaii, California, Oregon and Washington is less likely to occur and is typically less damaging.
