As property owners in the coastal regions of Norfolk, Virginia, you’re probably all too aware of the escalating risks posed by coastal erosion. This damaging effect of climate change has implications for your real estate, community infrastructure, and overall resilience to environmental challenges. Yet, the tide isn’t all doom and gloom. Given the proper planning, tools, and knowledge, you can mitigate these risks, reinforcing the longevity of your coastal properties and enhancing the sustainability of your community. In this article, we explore various strategies, from rolling easements to natural solutions, for safeguarding your coastal assets against sea-level rise and flooding.
Understanding the stakes: Coastal erosion in Norfolk
Before diving into potential solutions, it’s crucial to comprehend the severity of the issue at hand. Norfolk, a coastal city in the American state of Virginia, is no stranger to the threat of rising sea levels. With climate change accelerating, these threats are becoming more imminent.

The city’s location on the Atlantic Coast, coupled with its low-lying topography, makes it highly vulnerable to sea-level rise and coastal flooding. The city’s sinking land— a process known as subsidence— is exacerbating this vulnerability. The combination of sea-level rise and land subsidence is leading to more frequent and severe coastal flooding, thus accelerating erosion.
This escalating erosion is not only eating away at the city’s shoreline but also threatening homes, businesses, and critical infrastructure. It’s clear that action is needed to protect these assets and ensure the resilience of Norfolk’s coastal communities.

Implementing planning and zoning strategies
One of the initial steps you can take in mitigating the risks of coastal erosion involves appropriate planning and zoning. These terms might seem intimidating, but they simply involve the organization and management of land use within your community.
By incorporating sea-level rise and flooding into local planning and zoning regulations, you can encourage development that is better equipped to handle these challenges. For instance, building codes could require new constructions to be elevated above the anticipated flood levels. Zoning laws could restrict development in areas particularly susceptible to flooding or erosion.
In addition to these regulatory measures, you can consider adopting a ‘rolling easement.’ This strategy allows the sea to advance naturally, with property lines ‘rolling’ inland as the sea level rises. This strategy can succeed in maintaining a natural shoreline and reducing the long-term costs of erosion.
Enhancing community resilience
Building community resilience is an integral part of protecting your coastal properties. This means fostering a community that is not only physically capable of withstanding the impacts of coastal erosion, but that can also adapt and recover quickly when such events occur.
One way to foster resilience is through the enhancement of local infrastructure. This could involve the construction of sea walls, dikes, or other physical barriers to protect against the force of the waves and the tides. However, these solutions often come with high costs and potential environmental impacts.
Fortunately, there are other, more nature-based solutions that can bolster community resilience. These include the restoration of natural coastal habitats, like marshes and dunes, which can act as natural buffers against sea-level rise and coastal flooding.
Encouraging Nature-Based Solutions
Nature-based solutions capitalize on ecosystems’ inherent ability to protect coastlines. These methods are particularly relevant for you, coastal property owners, as they can provide effective and cost-efficient protection for your real estate.
Consider, for example, the restoration of oyster reefs. Not only do these reefs provide critical habitats for marine life, but they also form natural barriers that decrease wave energy, thereby reducing coastal erosion.
Another nature-based strategy is the conservation and restoration of coastal wetlands. These environments can act as sponges, soaking up excess water during floods, and gradually releasing it back to the sea.
Mobilizing for collective action
Lastly, it’s important to remember that mitigating the risks of coastal erosion is not a task that property owners should shoulder alone. The scale and nature of the challenge call for collective action.
This may involve lobbying for local and state authorities to invest in climate adaptation measures, or collaborating with non-profit organizations that specialize in coastal protection. By working together, you can leverage resources and expertise, and make a significant impact in securing the future of your coastal properties.
Remember, the success of these strategies depends on your active participation and commitment. So, let’s roll up our sleeves and steer the course for a resilient Norfolk coast.
Embracing Green Infrastructure and Living Shorelines
Actively integrating green infrastructure into the urban fabric of Norfolk can serve as a viable strategy to mitigate the risks of coastal erosion. Green infrastructure refers to a network of natural and semi-natural spaces that conserve ecosystems and provide essential services. In the context of coastal regions, these can include mangroves, wetlands, and green roofs.
These eco-friendly interventions often outshine traditional grey infrastructure, such as concrete seawalls and levees, in terms of cost-effectiveness and multifunctionality. They not only dampen the impacts of sea-level rise and storm surges but also enhance local biodiversity and provide recreational spaces for the community.
A specific type of green infrastructure that can be implemented along the Norfolk coast is “living shorelines”. These are soft, stabilized shorelines composed of natural materials such as plants, sand, or rock. Living shorelines can maintain coastal processes while reducing erosion and improving water quality. They are designed to absorb wave energy and increase resilience to storms, while also providing habitats for a variety of wildlife.
Moreover, living shorelines can adapt to changing conditions over time, increasing their long-term viability as a protective measure against sea level rise and coastal flooding. As a coastal property owner, embracing these green interventions can not only safeguard your property against erosion but also enhance its aesthetic and ecological value.
Adopting a Resilience Overlay and Improving the Resilience Quotient
Incorporating a resilience overlay into the city Norfolk’s zoning ordinance can help address the challenges of coastal erosion head-on. A resilience overlay is a tool that allows for stricter regulations in areas at high risk for natural disasters. It promotes the incorporation of flood resilience measures into both new constructions and renovations of existing buildings.
For instance, a resilience overlay could mandate the use of flood-resistant materials for construction or prescribe higher elevations for buildings in flood-prone areas. Such an overlay can help ensure that structures are designed to withstand the increasing threats of sea level rise and coastal flooding, essentially increasing the community’s overall resilience quotient.
The resilience quotient is a measure of a community’s capacity to absorb, recover, and adapt to the shocks and stresses of climate change. Boosting Norfolk’s resilience quotient would involve not just physical, but also social and economic adaptations. This could involve educating the public about coastal hazards, improving emergency response systems, and supporting local businesses in adopting sustainable practices.
Through active engagement with these resilience-enhancing strategies, you as a property owner can play a vital role in safeguarding your coastal assets and contributing to the long-term sustainability of the Norfolk community.
In conclusion, it is apparent that the risks of coastal erosion in Norfolk, Virginia are significant and complex, demanding comprehensive and forward-thinking solutions. While the situation is serious, there are numerous strategies available to property owners to mitigate these risks. These range from adopting planning and zoning strategies to enhancing community resilience, encouraging nature-based solutions, embracing green infrastructure, living shorelines, and improving the city’s resilience quotient.
Each of these approaches has its own set of benefits and challenges, but together they can contribute to a more durable and resilient waterfront community. The key is to remember that mitigating coastal erosion isn’t a task for property owners to shoulder alone. It requires collective action, commitment, and long-term planning.
The path towards a resilient Norfolk coast may be challenging, but with active participation, it is achievable. Future generations deserve to enjoy the same coastal beauty that we do today. By taking these steps to mitigate the risks of coastal erosion, we can ensure that they will.
