U.S. coastal regions have experienced approximately one foot of sea-level rise over the past century, with another foot expected within the next 30 years. This acceleration affects more than 47,600 coastal sites nationwide, including hotels, resorts, and tourism facilities. Over 5,500 facilities may face frequent flooding by 2100. For coastal property managers and hotel owners, understanding regional vulnerabilities is essential for long-term planning and investment protection. This four-part series examines coastal erosion challenges across America’s distinct coastal regions, beginning with one of the nation’s most economically significant and vulnerable shorelines: the Atlantic Coast.
Understanding Atlantic Coast Vulnerability
The Atlantic Coast from New Jersey through Florida represents one of the most economically valuable and vulnerable coastal zones in the United States.
Multiple factors elevate erosion risk:
- low-lying topography along barrier island systems,
- land subsidence in key areas, and
- exposure to both nor’easters and hurricanes.
The concentration of high-value coastal real estate means even smaller changes in erosion rates can have significant financial repercussions.
The Atlantic-Gulf coastal belt contains approximately 36 million hectares of protective wetlands providing roughly $360 billion in ecosystem services. These systems buffer wave energy and absorb storm surge, making wetland loss a direct concern for coastal hotel owners.
Property-Level Impacts: The Numbers Hotel Owners Should Know
Beach erosion along Atlantic barrier islands shows growing retreat rates affecting property values and guest experience. In the hotel business realm, the wider the shoreline a property has to offer, the higher the room rates and occupancy levels are likely to be.
Florida’s date is both comprehensive and revelatory of the critical risk infrastructure is facing. With 0.68 meters of sea-level rise (a conservative mid-century projection), approximately half of existing beaches would experience significant impacts, along with 74 airports, 1,362 hotels and motels, and over 19,000 historic structures. Projected losses reach tens of billions of dollars by 2050.
Beyond property damage, coastal highways experience increasing high-tide flooding, affecting guest access. Airport facilities face similar risks, disrupting travel infrastructure. Now, factor in maintenance costs for affected systems. In the meantime, long-term exposure assessments induce dropping property values and increasing insurance costs, where insurance is still available.

Regional Hotspots: From New Jersey to Florida
On the Atlantic Coast, local geography results in a variety of risk profiles. The mid-Atlantic region (New Jersey, Delaware, Maryland, and Virginia) shows elevated Coastal Vulnerability Index ratings. More specifically, the New Jersey shoreline and Chesapeake Bay region face particular challenges from nor’easter systems.
The Carolinas center on barrier island dynamics. The Outer Banks offers a good example in how to maintain tourism infrastructure on quickly evolving landforms. In Charleston and Wilmington, valuable hospitality assets occupy low-lying peninsulas requiring constant attention to flooding alerts. North Carolina faces among the highest wetland loss projections.
Further south, Florida’s Atlantic coast represents the largest concentration of at-risk tourism assets. Southeast Florida from Miami Beach through Palm Beach contains dense beachfront hotel development. The Jacksonville to St. Augustine corridor includes historic properties where erosion risks put pressure on heritage preservation. Rather than one single cause-effect dynamic, property managers and owners are looking at an equation. Storm surge patterns, subsidence rates, and geomorphology create distinct risk profiles requiring property-specific assessment.
The Wetland Factor: Natural Protection and Its Decline
Coastal wetlands provide essential protection by attenuating wave energy, absorbing storm surge, and stabilizing sediment. Their components (salt marshes, tidal flats, and coastal forests) create natural buffers reducing flooding and erosion. Sea level rise endangers these essential areas.
U.S. coastal wetlands face projections ranging from a 25% increase to a 97% decrease by 2100, depending on sea-level rise rates. Louisiana, North Carolina, and Texas face the highest loss risk, with implications for Atlantic Coast properties.
Wetland loss calls for more engineered solutions to protect coastal areas and their communities, whether entirely man-made like seawalls or nature-based like beach nourishment. Properties previously protected by natural systems may require significant capital investment in structural protection, involving higher maintenance costs and constant monitoring with an effect on long-term financial projections.

Financial Planning Considerations for Properties
Atlantic Coast hotel owners benefit from incorporating erosion and flooding trends into financial planning. Property values in high-risk zones increasingly diverge from historical patterns, and long-term exposure must be evaluated and incorporated. In response to risk models and increasingly frequent and intensifying weather events, insurance markets are shifting premiums, deductibles, and coverage availability.
Maintenance budgets require adjustment for recurrent flooding, saltwater corrosion, and increased emergency repairs. Capital improvement planning should consider property exposure horizons, particularly for projects with 20- to 30-year payback periods. Due diligence for acquisitions increasingly includes flood risk assessment, erosion rates, insurance costs, and projected changes over hold periods.
Looking Ahead
From New Jersey to Florida, Atlantic Coast hotel owners and property managers face measurable erosion challenges that require attention in operational and investment planning. With 1,362 hotels at risk in Florida alone and projected losses reaching tens of billions of dollars by mid-century, understanding location-specific vulnerabilities becomes essential. The combination of sea-level rise, wetland loss, and variable storm exposure creates a complex risk landscape. Different coastal segments, from the Outer Banks barrier islands to Florida’s urban beachfronts, present distinct risk profiles requiring tailored assessments.
In Part 2 of this series, we will examine the Gulf of Mexico coast, where subsidence, hurricane frequency, and different development patterns create unique challenges for coastal hospitality properties.
