Preparing Infrastructure for Coastal Disasters and Hurricanes

Introduction

Living along the coast is often romanticized as a peaceful and surreal lifestyle for many. Homeowners benefit from enjoying the unique social and cultural character of seaside communities. As a result, beachfront properties generally remain highly desirable and costly, sustaining strong and steady market demand.

Despite the appeal of coastal living, this seemingly perfect lifestyle comes with considerable risks. Tropical storms, coastal flooding, and hurricanes pose severe threats to lives, property, and infrastructure, often resulting in extensive damage and displacement of communities. Therefore, it is a necessity to adopt a proactive approach to safeguard communities and protect investments. This article explores effective strategies to enhance the resilience of coastal residences, focusing on retrofitting existing structures and designing new homes better equipped to withstand harsh weather conditions.

Virginia Tech

The Virginia Tech Coastal Collaborator (VTCC) operates as a land-grant extension program and, as such, utilizes Virginia Tech’s expertise and resources to foster collaborative partnerships to address coastal challenges and coastal resilience. (Rouse, 2022). As climate change worsens, coastal disasters may occur more frequently and increase in magnitude. Virginia Tech Coastal Collaborator’s ethos is to reduce climate change-associated risk, promote equity, assist communities, and strengthen coastal resilience across Virginia. The Collaborator’s efforts concentrate on stabilizing and protecting coastlines and the communities that depend on them. (Rouse, 2022). Resilient communities are essential to VTCC’s objectives. For that reason, ensuring that residents are kept informed and prepared to confront any ocean- or climate-driven hazards is crucial.

Addressing this issue can be approached in two primary ways: first, by implementing measures to strengthen the resilience of existing homes; and second, by advancing design standards, building codes, and construction practices to ensure that newly constructed homes are capable of withstanding severe weather events and the impacts that accompany rising sea levels.

The Problem

Coastal housing faces an increasing number of risks, such as sea level rise, erosion of sand dunes, tropical storms, and hurricanes, the last two causing the most direct damage. These are two weather phenomena that, while related, differ in intensity and destructive potential. According to a Weather.com article by Johnathan Belles, tropical storms typically bring sustained winds below 74 miles per hour, resulting in moderate damage to homes and infrastructure. When wind speeds reach 74 miles per hour or higher, these storms are reclassified as hurricanes. (Belles, 2017). Hurricanes are characterized by stronger winds, lower central pressure, and greater storm surge potential, leading to widespread flooding, structural damage, and long-term community disruption. Both types of storms draw energy from warm ocean waters by forming a low- pressure center. This draws in wind that forms storm clouds from the warm, moist air rising from the water, which can, in turn, produce high-speed winds, flying debris, and severe flooding that threaten coastal properties (UCAR).

The dangers extend beyond immediate structural impacts. The aftermath of these disasters often leaves behind significant amounts of debris from damaged homes, businesses, and public infrastructure. Materials such as vinyl siding, roofing adhesives and sealants, and fragments of concrete, brick, and cement can be washed into the ocean during storm surges and flooding, leading to significant environmental pollution.

The Storms

Residents living directly along the coastline may experience moderate impacts from an average tropical storm, including exterior damage to homes, flooding of streets and public access roads, and power outages lasting several hours to multiple days. In contrast, when a hurricane makes landfall directly over an area, it can cause catastrophic destruction, potentially rendering the home uninhabitable. Such events often cause severe flooding, widespread debris, and prolonged disruptions to essential services, including electricity, transportation, and access to emergency response services. This can increase the death toll even after the storm has passed.

Many of these impacts can be prevented or in the very least, mitigated if coastal residents are better prepared. While not all homes are located directly on the oceanfront, properties situated miles inland can still experience serious damage from heavy rainfall, flooding, and wind-driven debris such as lawn ornaments and fallen tree branches. An example of this happening is Hurricane Helene’s effect on Asheville, a mountain community located hundreds of miles inland. Helene overflowed the French Broad River, which flows through Asheville, causing deadly flooding and destruction, displacing thousands, washing away businesses and homes, and causing lasting damage for months of cleanup and rebuilding efforts (Jacobo, 2024).

Once the Hurricane moves far enough from the ocean, its path may curve back over warm waters and regain strength, or continue farther inland, causing damage over a wide area. Eventually, as it loses access to the ocean’s energy, the storm weakens and gradually dissipates, often downgrading to a tropical storm. (IERE, 2025)

Community Effects

The damage associated with severe storms extends far beyond the destruction of individual properties and shorelines. These events can destabilize and disrupt entire communities and regions. The intricate social and economic networks that support coastal regions can rapidly deteriorate in this aftermath. Prospective property buyers who were once attracted to the perceived advantages of living on the coastline may be deterred upon observing how quickly residents experience irreversible loss and damage. Existing homeowners may be compelled to abandon their homes and relocate to safer dwellings.

Furthermore, when storm damage is irreparable, property values often plummet sharply, forcing many homeowners to sell at a substantial loss. Additionally, local economies suffer as businesses may encounter a myriad of challenges, including mounting expenses from flooding and high winds and prolonged utility outages. As these businesses struggle to recover, layoffs become more frequent, reducing household incomes and making it increasingly difficult for residents to maintain their properties—fueling a cycle of economic decline that can prove challenging to reverse.

The disruption caused by severe storms can be particularly devastating for minority communities, especially those built around low-income housing. These communities often rely heavily on mutual support networks; when a storm destroys the neighborhood, survivors may be left without essential social support. This breakdown can lead to widespread and prolonged homelessness.

Low income housing is more vulnerable to destruction during powerful storms. This is due to outdated and lower quality construction materials. According to a 2020 study by Chenyi Ma and Tony Smith, during Hurricane Maria, Puerto Rican families who lost their entire homes had an average income less than half that of families who sustained only minor damage. (Ma, Smith, 2020).

Another example of the devastating effects storms can have on communities is Hurricane Katrina, one of the worst natural disasters in U.S. history. Katrina struck New Orleans, a city that, according to a 2005 Brookings Institution study by Berube and Katz, had the second-highest percentage of poor residents living in extremely impoverished neighborhoods

when compared to the nation’s largest cities, which is quantified by having an average annual income under 20,000 and living in neighborhoods where the poverty rate exceeded 40%. (Berube and Katz, 2005). The city’s pre-existing socioeconomic vulnerabilities made it particularly susceptible to disasters affecting infrastructure and disproportionately devastating already marginalized communities. Thousands of residents were left stranded, frightened, and waiting for rescue for days. Even two decades later, the storm’s impact continues to be felt throughout both the community and the city as a whole. (History, 2025). Figure 1 shows the extent of the flooding in residential areas of the city.

How to Prepare

To secure a home that is at risk from an approaching storm, vulnerable points susceptible to wind, water, and flying debris should be reinforced or fully covered. Windows are a critical starting point and should be boarded up with sturdy plywood to protect the glass and help insulate the home. Similarly, doors made of thin wood or mesh screens should be reinforced to prevent damage and improve overall storm resistance.

Wind and Flooding

If a storm with dangerously high winds is approaching, it is essential to secure the roof of the house and any additional structures, such as sheds, gazebos, guest houses, and carports. According to Olin Wade of Remodel or Move, one effective method to secure structures is to install steel anchors into nearby concrete bases or supports and use them to fasten durable cables or ropes over and around the structures, helping hold them in place during strong winds (Wade). Smaller outdoor items, such as grills, potted plants, and umbrellas, should be brought indoors to prevent them from becoming hazardous projectiles.

Seal outside vents, openings, doorways, and window cracks with storm-ready sealant products such as Flex Tape and Flex Seal. (Burns 2024, Flex Seal Products 2025). If possible, move valuable items and electronic equipment to higher floors to protect them from water damage.

Emergency Preparation

Designate a safe room or rooms to shelter when a storm approaches. Ideally, this should be an interior room without windows or exterior doors, such as a bathroom or closet, that protects from flying debris. This would be low to the ground ideally, but if flooding prevents doing so, move to the next lowest level. Purpose-built safe rooms may feature concrete-reinforced walls or steel doors, but in most homes, a sturdy interior room without openings to the outside can offer adequate protection.

Keep an ample supply of water in the designated safe room. The Centers for Disease Control and Prevention (CDC) recommends storing at least 1 gallon of water per person per day; for example, a family of five should have 15 gallons of water available for a 3-day emergency. This water should be reserved for essential needs such as drinking, cooking, and basic hygiene. It is important to note that the expiration date printed on bottled water typically refers to the bottle, not the water. Over time, especially after this date, plastic bottles can begin to deteriorate, potentially allowing bacteria to enter and release chemicals such as Bisphenol A (BPA) into the water. Exposure to BPA, particularly when bottles are stored in heat or direct sunlight, may disrupt hormones, impair brain development, and increase the risk of chronic conditions such as asthma and diabetes. To ensure safety, periodically replace stored bottled water before the packaging begins to degrade. (CDC, 2025).

Maintain a substantial supply of non-perishable food items such as canned fruits, vegetables, and fish. Dried fruits and jerky are also useful to have on hand. When selecting provisions, prioritize natural products that are low in added sugar to ensure balanced nutrition during an emergency. Non- perishable hygiene products are equally important. Stock up on essentials such as soap, shaving supplies, deodorant, dental care items, and feminine hygiene products. In the event of limited toilet access, keep buckets and trash bags readily available for sanitation. If caring for infants includes an adequate supply of diapers and baby wipes, baby wipes can also serve as a practical option for personal cleaning when water is limited. If evacuation becomes necessary, ensure that two emergency preparedness kits are ready, one stored in a secure location at home and another kept in the car. Each kit should include essential supplies such as non-perishable food, flashlights, a battery- powered or hand-crank radio, cash, medications, and other critical emergency items. Before leaving, turn off all utilities to reduce potential hazards, securely lock all doors, and evacuate safely following recommended routes and official guidance.

Improvement through Renovation

Although enhancements at the resident level play a crucial role in reducing storm damage, a more effective long-term approach is to integrate resilient construction techniques into the renovation or construction process. By making structural modifications, homes can be significantly better equipped to withstand powerful natural forces such as high winds and flooding. Scarano Architecture firm provides resistant design tips in their article “An Architect’s Guide to Designing Homes to Withstand Hurricanes.” When preparing for extreme winds, additional roof support may be necessary to prevent the roof from being torn away from the house. Begin by using the previously mentioned method of securing the roof with ropes and anchors. Whenever possible, have a professional install a durable metal roof. Keeping the structure dry during and after a storm is critical, as interior water damage can cost thousands of dollars to repair. (Scarano Architect, 2024)

Improvement through Design

The renovations discussed earlier can be highly effective in strengthening a home against natural forces.

However, existing structures often present challenges that limit these improvements. Foundations may have shifted due to unstable ground; homes built too close to the water may face ongoing flooding risk; and tall, narrow houses are inherently more vulnerable to strong storm winds. In such cases, the most dependable, albeit more expensive, solution is to invest in a newly constructed home. With the rising demand for beachfront living, many future properties will be built from the ground up, providing an opportunity to integrate storm-resilient design principles and modern construction techniques from the start. This approach ensures a stronger, more durable home that can withstand severe weather events.

Wind Damage

When constructing new beachfront homes, most architects choose raised foundations, which elevate the structure above areas typically impacted by storm surges. While these elevated designs may appear more vulnerable to strong winds due to their height, they are firmly secured with reinforced concrete for added stability. (Weinhofer, 2023)

To further reduce the impact of strong winds, homes can be designed with aerodynamic features. Sloped roofs, rounded edges, and horizontally oriented layouts help channel wind around the structure rather than directly against it. In addition to improving storm resilience, these aerodynamic design elements can enhance the home’s visual appeal, making it more attractive to potential buyers. (Scarano Architect, 2024).

Materials

To withstand powerful forces of nature such as hurricanes, a home must be built on a solid foundation using durable materials like concrete, brick, or stone. These materials are highly resistant to wind and water, providing structural integrity and minimizing the risk of damage during severe weather events. (Scarano Architect, 2024).

Making the Right Choice

A strong case can be made for both renovating an existing home and constructing a new one. Neither option is inherently superior; each offers advantages that suit different homeowners and circumstances. Renovating an existing property is generally less expensive and preserves the sentimental value attached to the home and land. It also allows residents to remain within their familiar community, avoiding the stress of purchasing and relocating to a new property. Renovations provide flexibility, enabling homeowners to select trusted contractors and customize materials and designs to their preferences. However, renovations can also uncover hidden structural problems such as rotting wood or termite damage, which may significantly increase costs. If the existing home fails to meet current building codes, bringing it up to standard can become more expensive than purchasing a new property. Additionally, extensive renovations can take months to complete, causing ongoing disruptions from construction noise and dust. In severe cases, temporary relocation may be necessary, adding further expenses‌

The alternative and often more popular option is to purchase a newly built, hurricane-resistant home. These homes are constructed to meet current building codes and include advanced safety features that can reduce insurance premiums and increase resale value. Unlike renovation projects, new homes involve no ongoing construction work or unexpected repair costs, and maintenance requirements are typically minimal in the early years. Additionally, buyers can choose a location with lower flood risk, providing an added layer of protection against future storms.

Conclusion

Every coastal citizen should consider the dangers posed by Tropical Storms and Hurricanes. Houses that are especially susceptible to storm damage should be renovated to improve structural resistance, and new houses should be built to meet those standards. Be proactive in supplying the home with emergency materials and know what to do in situations that call for evacuation.

This dilemma can be viewed on a larger scale--- if the government wanted to strengthen the population of the coast by improving their housing situation, they could change building codes or invest in a new housing and development project. This is a realistic idea; the residents of the coast just need to make their voices heard. Push for a policy that benefits the coastal environment and improves resilience to dangerous weather.

Focusing back on the Virginia Tech Coastal Collaborator and Virginia’s increasingly vulnerable and storm-prone east coast, it’s clear that this region can be an extremely dangerous place to live in the event of coastal disasters. Citizens should always be prepared for storms and ensure their homes are secure if they plan to return. With this information, Virginia’s resilient communities will continue to thrive.
