Turning Coastal Resilience into Coastal Opportunity
Coastlines have always played a defining role in shaping cities and destinations. However, as environmental pressures intensify, cities must rethink how they plan, design and manage their waterfronts. Lee Adam Harryman, Senior Vice President and Head of the Climate Resilience Studio at CPG Consultants, shares his perspectives on why the future of coastal resilience is about creating value, not just managing risk.
Many coastlines are facing growing pressures from sea-level rise, more intense storm events, changing rainfall patterns and coastal erosion. For governments, developers and communities, the challenge extends beyond protecting the coastline to ensuring waterfronts remain vibrant, attractive and economically viable for future generations.
This requires a shift in thinking from coastal protection to creating long-term value through resilient coastal development.
Looking Beyond the Shoreline
Coastal erosion is not simply a matter of beach sand loss. It is driven by interconnected factors such as sea-level rise, intensified wave action, storm surges, land subsidence and urban development. These changes often have cascading impacts on drainage networks, flood risk, transport infrastructure, utilities and ecosystems.
Globally, coastal communities are facing more frequent tidal and storm-related flooding, shoreline retreat and growing pressure on critical infrastructure. Low-lying island nations and coastal tourism destinations are particularly vulnerable because they have limited opportunities to retreat inland.
The challenge therefore extends beyond managing the coastline itself. It is about understanding how water interacts with the wider urban environment and planning for resilience from a systems perspective.
Why Climate Resilience Demands a New Approach
Traditionally, coastal protection has been approached primarily as an engineering challenge, with seawalls, revetments and flood barriers used to minimise risk and protect assets. While these measures remain important, they are no longer sufficient on their own.
Today’s coastal cities must safeguard not only infrastructure, but also economic activity, public spaces, ecosystems, communities and quality of life. The focus is no longer simply on defending the coastline, but on ensuring waterfronts remain functional, liveable and resilient.
This requires a multidisciplinary and integrated approach. Water systems, infrastructure, ecosystems and communities are closely interconnected, and resilience depends on collaboration across engineering, planning, environmental, design and policy disciplines. The most resilient cities are those that take a holistic view of how these systems interact and support one another.
Making Better Decisions Through Water Modelling
As climate risks become more complex, informed decision-making is increasingly critical. Reliance on historical data alone is no longer sufficient, as future climate conditions may differ significantly from past experience.
This is where water modelling plays a critical role. Advanced modelling tools allow planners and engineers to simulate flood behaviour, stormwater flows, coastal processes and future climate scenarios before development takes place. These insights help decision-makers assess risks, test interventions and identify opportunities long before infrastructure is built.
Water infrastructure is also being considered much earlier in the planning and feasibility stages. When stormwater management and water resilience strategies are integrated upfront, land can be used more efficiently, infrastructure can be phased more strategically, and long-term operational and maintenance costs can be reduced.
In this sense, water modelling is not simply a technical exercise. It is a decision-making tool that helps cities optimise investments, maximise land value and create developments that are better prepared for future conditions.
Designing Infrastructure That Creates Value
One of the most significant shifts taking place in coastal resilience today is the move away from single-purpose infrastructure towards solutions that deliver multiple benefits simultaneously.
Historically, coastal protection projects were measured primarily by their engineering performance. Success was defined by how effectively they reduced flooding, managed erosion or protected assets.
Today, every metre of coastline represents an opportunity to create broader value.
A flood barrier can become a waterfront promenade. Elevated landforms can provide recreational spaces and biodiversity habitats. Nature-based solutions such as mangrove restoration, living shorelines and ecological buffers can reduce wave impacts while enhancing environmental quality and visitor experiences.
Rather than treating resilience infrastructure as a cost, cities are increasingly recognising it as an investment in better places.
This philosophy is reflected in projects around the world. The Netherlands’ Sand Motor demonstrates how working with natural coastal processes can support shoreline protection, recreation and tourism simultaneously. Closer to home, Singapore’s Long Island initiative is exploring how future coastal protection infrastructure can be integrated with public spaces, community amenities and future development opportunities.
These examples highlight a broader principle: resilience infrastructure should not merely protect places. It should help create them.
Creating Destinations for the Future
For tourism destinations, an integrated approach to coastal resilience presents significant opportunities. Visitors increasingly seek destinations that combine authentic experiences, environmental stewardship and strong connections with nature, allowing resilience measures to enhance destination appeal rather than function solely as protective infrastructure.
The future of coastal tourism will depend not only on managing climate risks, but also on creating sustainable, memorable and resilient visitor experiences. By integrating resilience, water management, infrastructure planning and place-making from the outset, destinations can develop waterfronts that are safer, more attractive and more valuable over the long term.
From Protection to Opportunity
The future of coastal development will not be defined solely by how effectively cities defend against rising seas and stronger storms, but by how successfully they turn these challenges into opportunities to create more liveable, sustainable and resilient places.
At CPG, we believe resilience should not be viewed simply as protection against risk. It should be seen as a catalyst for better planning, smarter investments and stronger communities. By combining multidisciplinary expertise, data-driven decision-making and integrated design, cities can move beyond protecting their coastlines to creating destinations that continue to inspire visitors, support communities and generate value for generations to come.
Ultimately, the goal is not just to protect places, but to create destinations that thrive in a changing world.
