Executive Summary The 2015 CoreLogic storm surge report provides insight into the number and value of single-family residential property exposure to Atlantic basin storms in the U.S. Both the Gulf and Atlantic coasts are susceptible to hurricane-driven storm surge and, as this report shows, even at the local level, the potential damage could easily total billions of dollars for a single event. The likelihood for flood damage caused by storm surge is not just limited to isolated locations along the coast, and certain areas are more vulnerable than others. As Hurricane Sandy demonstrated just three years ago, one storm is all it takes to cause a tremendous amount of property damage in a densely populated area. The analysis conducted for this year s storm surge report evaluates and provides insight on: The number of homes at risk of storm surge. The reconstruction cost value (RCV) to completely rebuild those residential dwellings. Both of those factors in total and at various geographic levels. Metropolitan-level analysis. Current projections for the 2015 hurricane season indicate that fewer storms are expected compared with the 30-year average for the Atlantic basin, but as history has demonstrated, it is not only the number of storms that should be of concern, but also the location of the storms. 1 The threat of a storm that may push onshore in a place that is vulnerable to storm surge is ever present, and annual preparation and planning for these types of events will always be necessary. 2015 CoreLogic, Inc.

2015 CoreLogic Storm Surge Analysis This year s analysis reveals that a total of more than 6.6 million homes along both the Gulf and Atlantic coasts of the U.S. are at risk of storm surge damage. The total RCV of these structures is estimated at nearly $1.5 trillion (Table 1). Reconstruction cost values are based on materials, equipment and labor costs, and it is common for these costs to fluctuate over time. Additionally, RCV is based on total or 100-percent destruction of the residential structure. Depending upon the amount of surge water from a given storm, the amount of flooding that occurs could very well cause less than 100-percent property loss, which would result in a lower realized rebuilding cost.

Although Pacific-based storm damage occurred in 2014, those storms minimally impacted Hawaii and the western coast of the U.S. compared to the more frequently occurring storm damage that originates in the Atlantic basin. The Gulf and Atlantic coasts are the areas of the U.S. most commonly affected by storm surge flooding. The homes studied in this analysis are located in 19 states and the District of Columbia the areas that are most susceptible to storm surge damage along the eastern and southern coasts. Florida tops the list as the state with the most properties at risk, with 2.5 million homes potentially affected and $491 billion in associated RCV (Table 2). The metropolitan region with the highest risk is the New York City Core Based Statistical Area (CBSA) (Table 5). The New York City CBSA, which includes Long Island and a portion of New Jersey, has a total of 685,152 homes at risk with an RCV of $244,312,501,442. Storm Surge Risk Along the Atlantic and Gulf Coasts Although storm surge risk varies along the Gulf and Atlantic coasts, there is no location along these shorelines that is completely free from the risk of storm surge. Even though portions of the Gulf and southeastern Atlantic coastline rank highest in potential damage, areas as far north as Massachusetts and Maine are also vulnerable to storm surge. A comparison of risk in the Gulf region to the risk present along the Atlantic shore highlights the increased number of homes and higher total RCV for the Atlantic coastal properties. The total number of homes in a surge risk zone along the approximately 2,050 miles of the Atlantic Coast is just over 3.8 million. This is in comparison with the 1,600- mile stretch of Gulf Coast, with homes at risk totaling nearly 2.8 million. Since there are fewer homes at risk along the Gulf Coast, the associated RCV is lower than the Atlantic RCV as well, at $549 billion and $939 billion, respectively. 6

It is important not to underestimate the risk along the Gulf Coast, which extends from Texas through the western coast of Florida. It can be very susceptible to storm surge flooding, and historical hurricanes such as the Galveston Hurricane of 1900, Hurricane Camille in 1969 and Hurricane Katrina in 2005 were all tremendously damaging events that caused extensive property destruction and hundreds, or in the case of Galveston and Katrina, thousands of deaths. 2 Table 3 Residential Exposure by Coastal Region Regional Atlantic Coast Atlantic Coast Gulf Coast Gulf Coast RCV Risk Homes RCV (U.S. Dollars) Homes (U.S. Dollars) Extreme 1,018,371 $264,963,399,509 633,607 $128,531,352,565 Very High 911,091 $223,821,396,433 527,435 $100,404,022,574 High 860,657 $212,741,476,684 794,268 $158,393,610,710 Moderate 686,061 $172,277,118,076 492,135 $95,118,854,144 Low 332,984 $65,334,507,800 352,407 $66,755,734,253 Total 3,809,164 $939,137,898,502 2,799,852 $549,203,574,246 Source: CoreLogic 2015.

Storm Surge Risk by State The number of properties and the total RCV within each surge category varies by state based on the length of the coastline, the amount of residential development and population, as well as the geographic factors that define the storm surge risk. States with extensive coastlines, such as Texas and Florida, will always be expected to have larger numbers of residential properties at risk. Florida ranks first for the number of properties at risk and Texas as fifth (Table 4). As expected, these two states also rank highly for RCV, at first place ($491 billion) and sixth place ($78 billion), respectively (Table 2). Even states with smaller coastal exposure but lower-lying elevations that extend farther inland, such as Louisiana (2nd) and New Jersey (4th), tend to have higher total properties at risk since the surge water may travel farther inland. For example, in 1957, Hurricane Audrey pushed surge waters an estimated 25 miles into southwestern Louisiana. New Jersey and Louisiana are also near the top of the list for RCV, with the New Jersey coast totaling $126 billion (4th) and Louisiana at $162 billion (3rd). Finally, states with high population density along the coast, such as New York, are similarly going to have higher numbers of properties at risk and often have a higher associated RCV as well. While New York has less total coastline and much less surge-prone areas than other states, it does have a large and dense population located within the surge risk area. The total number of properties at risk in New York state sits at 464,534 (3rd) and the total RCV is more than $177 billion (2nd). 8

Storm Surge Risk in Major Metropolitan Areas To evaluate storm surge risk at the local level, CoreLogic uses CBSAs defined by the U.S. Office of Management and Budget, often referred to as a metropolitan (>50,000 people) or micropolitan (<50,000 people), which represent 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 15 U.S. cities with the greatest number of homes potentially affected by hurricanedriven storm surge are listed in Table 5. Approximately 65.4 percent of the 6.6 million homes and 66.3 percent of the total $1.5 trillion RCV for the U.S. is located within these 15 CBSAs. Ultimately, this concentration of residential properties reinforces the idea that the location of future hurricane events is often times more important than the number of storms that occur during the course of the year. As Hurricane Sandy proved in New York, Hurricane Andrew in Miami and Hurricane Katrina in New Orleans, a single damaging storm located near one of these 15 metro areas is likely to be exceedingly costly in terms of both property and lives. 10

Storm Surge Inundation Versus Freshwater Flooding Flood risk evaluation within the U.S. has often been within the purview of the Federal Emergency Management Agency (FEMA). FEMA has been a long-time provider of flood boundary designations that incorporate storm surge analysis. Flood Insurance Rate Maps (FIRM) are the FEMA products that illustrate both the 100-year and 500-year floodplains, and are used to delineate homes required to carry flood insurance based on location within a designated FEMA 100-year floodplain. 3 Based on the FIRM maps, a property is located either within or outside of a designated 100-year flood zone, and thus is determined to require flood insurance or not. 3 This in or out analysis is effective at making a broad determination of risk; however, often it does not indicate the gradation of risk that occurs both within and outside of the 100-year boundary. The CoreLogic storm surge analysis incorporates multiple storm categories and, as a result, that level of risk evaluation reveals differing results in the overall analysis of homes at risk of storm surge inundation. In some areas, additional homes and regions outside designated floodplains have been identified at risk of surge inundation. To illustrate these varying degrees of flood risk exposure, the CoreLogic analysis in Table 6 compares homes that are not located within FEMA 100-year floodplains against the number of homes located in surge inundation zones, as well as those located in both surge and FEMA Special Flood Hazard Areas (SFHA) for 15 select major metro areas. Since standard homeowner s insurance excludes flood losses from either fresh or salt water, homeowners who are not located in FEMA SFHAs often do not consider buying National Flood Insurance Program (NFIP) coverage for their properties even though they are located in high-risk surge zones. 12

Storm Surge Methodology: Categories and Valuations for Homes at Risk in 2015 The 2015 CoreLogic storm surge analysis encompasses single-family residential structures including mobile homes, duplexes, manufactured homes and cabins, among other nontraditional home types. Year-over-year changes in the number of homes at risk and 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 potential rise in sea level. As a result, direct year-over-year comparisons should be avoided. To estimate the value of property exposure of the single-family residences, CoreLogic utilized Marshall & Swift/Boeckh reconstruction cost valuation methodology. 4 This methodology estimates the cost to rebuild the property 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, and also factor in geographical pricing differences. Actual land values are not included in the estimates. The values are based on 100-percent or total destruction of the residential structure. Depending upon 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 reconstruction cost value. 14

Storm Surge Overview What Is Storm Surge? Storm surge is a complex phenomenon that occurs when water is pushed toward the shore through the force of powerful winds associated with cyclonic storms, and is further influenced by many different factors, including water depth and ocean floor terrain. High winds and low pressure created by a storm cause water to accumulate at its center. As it moves across the ocean, the strong winds inside the hurricane act as a plow, causing water to pile up along the front of the storm, with the highest water levels accumulating along the right-front quadrant as the hurricane spins counterclockwise. The speed at which a hurricane moves along its path can be highly variable, even for a single storm. The surge levels created by a fast moving storm are likely to be higher than for a slow storm. Conversely, for a slower moving hurricane, a larger volume of water is pushed due to the fact that it takes more time for the storm to move inland and dissipate. The hydraulic impact created by these waves tends to be incredibly destructive because each cubic yard of seawater weighs approximately 1,728 pounds nearly one ton. 17-ft.

Insights and Findings A Look Back at 2014 2014 TROPICAL STORM SEASON HURRICANES AND TROPICAL CYCLONES The 2014 Atlantic hurricane season experienced a continued decline in the number of Atlantic-based storms, totaling fewer than the 2013 season in terms of total storm activity. While 2013 had no actual hurricanes that made landfall in the U.S., there was a single storm in 2014 that caused relatively minimal damage along ARTHUR CATEGORY 2 EDOUARD CATEGORY 3 GONZALO CATEGORY 4 the eastern coastline. 5 Hurricane Arthur (Category 2), the first storm of the season and also the earliest hurricane ever to make landfall in North Carolina, pushed onto the Outer Banks over the Fourth of July weekend. The path of Arthur kept the storm from causing severe damage, as it paralleled the U.S. coast on a northeastern track before moving into Canada. Arthur was the first of nine tropical cyclones in 2014, eight of which were named. Together, they reflected the lowest total number of storms during the Atlantic hurricane season since 1997. Of the eight named storms, six became hurricanes with wind speeds of at least 74 mph, and two of the six grew into major hurricanes which are defined as a Category 3 or higher (111 mph or greater). 5 The two largest storms of the year did not impact the U.S. Hurricane Edouard (Category 3) never came close to making landfall and eventually died out in the Atlantic. Hurricane Gonzalo (Category 4) was the strongest Atlantic storm of the year, and although it did not come ashore along the U.S. coast, it did cause extensive damage in Bermuda, with 86 percent of residents losing electricity due to the storm. Similar to the factors causing the reduced numbers in 2013, the reasons for a calmer season in 2014 were based on strong vertical wind shear, dry air and convergence (sinking air masses) in the eastern and central Atlantic basins. 16

2015: A Pre-Season Forecast The preliminary forecast for the 2015 hurricane season, which runs from June through November, indicates a season very similar to that of the last two years. The 30-year Atlantic hurricane season average is 12 named storms, with six of those producing hurricanes and three becoming major hurricanes. 1 For the 2015 season, The Weather Channel s most recent forecast predicts nine named storms, five hurricanes and one major hurricane, indicating a slight downward shift from the 30-year average numbers that are very similar to those experienced in 2014. The Colorado State forecast, led by Dr. Phil Klotzbach and Dr. William Gray, is also very similar to the 2014 season, with a prediction of seven named storms, three hurricanes and one major hurricane. 1 Another view of the 2015 season comes from an early prediction by the Tropical Storm Risk Center which also indicates a below-average year with 11 tropical storms, five hurricanes, and two major hurricanes. 6 Tropical Storm Ana 2015 While the 2015 hurricane season always begins June 1, it does not prevent Atlantic storms from forming earlier. The first storm of this year formed off the Carolina coast between May 7-9 when it achieved tropical storm status. After making landfall near Myrtle Beach, S.C., Tropical Storm Ana dropped nearly six inches of precipitation in various locations but caused minimal damage along its path. While Ana was an early storm, it was not unique as there are numerous instances of Atlantic storms forming prior to June 1. More importantly, the occurrence of a storm in early May is not necessarily an indicator of activity for the coming hurricane season. 2015 CoreLogic, Inc. Proprietary and confidential.

Hurricane Katrina: A Look Back After Ten Years During the last week of August 2005, one of the worst hurricane-related disasters in U.S. history played out in the Gulf of Mexico. It was an active year for Atlantic storms, with ten named storms already on the books prior to the formation of Hurricane Katrina in late August. Overall, 2005 set an Atlantic-basin record for both named storms (28) and hurricanes (15), and came in second for the number of major hurricanes with seven forming that year (only 1950 had more, with eight). The storms were relentless during the summer, with the formation of one or more tropical storms in the Atlantic every week from July through October. 7 Early forecasts for 2005 had indicated above-average hurricane activity, but since the averages for the 55-year period from 1950-2004 were 9.9 tropical storms, six hurricanes and 2.6 major hurricanes, there was little evidence or inclination that the numbers would nearly triple that year. 8 Katrina formed near the Bahamas on August 23 and tracked through the islands before strengthening to a Category 1 storm just prior to making landfall along the southern tip of Florida. Katrina moved quickly across Florida and made its way into the Gulf of Mexico, where it spent the next couple of days strengthening as it then moved towards Louisiana. The storm became a Category 5 hurricane on its journey through the Gulf, with winds of 175 miles per hour. Katrina faded slightly and was downgraded to a Category 3 storm as it made landfall just southeast of New Orleans. 18

The aftermath of Katrina is a natural disaster of epic proportions. There were more than 50 breaches in the levees in and around New Orleans that allowed the surge and flood waters to devastate the city and surrounding communities. More than 80 percent of New Orleans was underwater after the storm moved through, and more than 1,800 people perished during and after the storm s passing. Property damage climbed to $125 billion, making it the most costly hurricane on record in terms of property loss and the third deadliest hurricane ever to hit the U.S. 9 Even ten years later, the rebuilding of the area is still ongoing. The system of levees and pumping stations has been enhanced and reinforced in the aftermath of the storm, and nearly $15 billion has been spent on preparing for the inevitability of the next storm that will impact the area. sources: 1 The Tropical Meteorology Project - http://hurricane.atmos.colostate.edu/forecasts/ 2 National Hurricane Center - http://www.nhc.noaa.gov/outreach/history/ 3 Federal Emergency Management Agency, 2015. 4 CoreLogic acquired Marshall & Swift/Boeckh in March 2014 5 Wikipedia.org: 2014 Atlantic hurricane season, 2014 6 Tropical Storm Risk - http://www.tropicalstormrisk.com/ 7 National Hurricane Center - www.nhc.noaa.gov/data/tcr/index.php?season=2005 8 Tropical Storm Risk - https://www.tropicalstormrisk.com/docs/tsratlforecastjul2005.pdf 9 Wikipedia.org: 2005 levee failures in Greater New Orleans 2015 CoreLogic, Inc.
