  • Gold Coast Seawalls: A Private Homeowner’s Guide to Protecting Beachfront Property

    Living by the ocean offers great views and a unique lifestyle, but it also comes with challenges like coastal erosion and storm surges. For beachfront homeowners, Gold Coast seawalls aren't just a smart investment - it’s a requirement under the City of Gold Coast’s City Plan to protect your property and the surrounding coastline.  At International Coastal Management (ICM) , we make the seawalls construction process seamless. From design and certification to final construction sign-off and dune restoration, we handle every step with expertise.  Why Do You Need a Seawall?  Coastal erosion is a natural process, but it can become a significant risk during storms or high tides. Without adequate protection, your property could lose valuable land or face structural damage.  Seawalls in Australia are one line of defence for coastal erosion. On the Gold Coast, it is the responsibility of private property owners  to construct and maintain a seawall (to council standards). These are designed to:  Prevent property loss and reduce damage from storms.  Comply with regulations by meeting City Plan requirements for beachfront properties.  Enhance longevity    The Gold Coast A-Line  The A-Line is the approved alignment for seawall construction along the Gold Coast beaches, established after severe erosion in the 1960s and 1970s. It ensures a consistent and connected seawall system along the coastline, protecting both public and private properties.  At ICM, we design seawalls that perfectly align with the A-Line, ensuring they meet Council requirements and integrate seamlessly into the coastal landscape.  Steps to Building a Private Seawall on the Gold Coast  Building a seawall on the Gold Coast can seem complex, but with ICM, it doesn’t have to be. We’ve simplified the Gold Coast City Council’s 11-step process into manageable actions, ensuring compliance at every stage:  1. Understand the City Plan Requirements  Before beginning, review the City Plan Coastal Erosion Hazard Overlay Code  and related guidelines and requirements . These documents outline the technical and regulatory standards for seawall construction.  ICM Support: Our team breaks down the technical jargon, ensuring you know exactly what’s required.  2. Get the Necessary Approvals  You’ll need development applications approved by both the City of Gold Coast and relevant Queensland Government departments for tidal or prescribed tidal works.  ICM Advantage: We handle the paperwork for you, from State Government approvals for tidal works to Council permits.    3. Submit the Security Deposit  The City of Gold Coast requires a minimum bond of $16,745 before work begins, ensuring satisfactory restoration of dunes and infrastructure, certification and approvals.  Why ICM: We'll guide you through the deposit requirements, and ensure your seawall and dune system is built to council standards so your bond can be returned promptly after project completion.    4. Design and Certification  Your seawall must be designed by a Registered Professional Engineer of Queensland (RPEQ) to meet Council standards.  Why ICM: Our RPEQ-certified engineers bring decades of experience to create designs that are durable, compliant, and environmentally integrated.  5. Pre-Construction Activities  Prepare for construction by managing temporary road/pathway closures and ensuring minimal disruption to public access.  ICM’s Full-Service Approach: We manage all pre-construction logistics, including obtaining necessary permits.  6. Construction of Seawall  Work with a qualified contractor to construct your seawall to Council standards.  ICM Expertise: We oversee construction to ensure quality and compliance every step of the way.  7. Restore the Dune and Vegetation  After construction, dunes must be reformed with clean sand, native vegetation planted, and dune fencing installed.  Our Complete Solution: We integrate dune restoration to ensure your seawall functions as part of a resilient coastal system to council standards. 8. Final Certification and Inspections  Submit certifications and inspections to the City of Gold Coast for final approval.  ICM’s Commitment: We ensure your seawall and dune system meet the highest standards.   Gold Coast Coastal Management To counteract Gold Coast erosion, there are a range of innovative and multifaceted coastal protection measures implemented. Combining coastal protection structures, artificial reefs (like the Narrowneck Artificial Reef ), beach nourishment , and stable dune systems, the region addresses erosion and ensures resilient coastlines. Additionally, sand bypassing and backpassing maintain natural sediment flows, while native vegetation stabilises dunes, providing critical storm buffers and wildlife habitats. This holistic approach balances environmental, community, and surf amenity benefits, safeguarding the coastline for future generations. FAQ: Your Seawall Questions Answered  1. How long does seawall construction take?  The timeline varies depending on the complexity of the site but typically ranges from 4 to 5 months. The design and construction of a seawall can be relatively quick (2-4 weeks), however the approval process can take up to 4 months. 2. What’s the typical cost of a seawall?  Costs vary based on site conditions, materials, and regulatory requirements. We provide a tailored quote after an initial site assessment.  3. Do I need a seawall if I already have dunes?   Dunes are an essential part of coastal resilience but may not be sufficient on their own. Terminal seawalls provide a critical defence against wave action and erosion, especially during storms.  4. Can ICM handle the entire process?  Yes! From design and approvals to construction management and dune restoration, ICM offers an end-to-end solution tailored to your property’s needs.  5. Why is dune restoration necessary after building a seawall?  Dunes stabilise the area, reduce wind erosion, and enhance the natural resilience of your property. Dune restoration helps your seawall works in harmony with the environment, and is a requirement from the Gold Coast City Council.  ICM’s Expertise in Seawall Construction  ICM provides end-to-end seawall solutions, including:  Design:  Engineering seawalls to meet Gold Coast standards.  Construction:  Managing the building process (working with local contractors) from start to finish.  Regulatory Compliance:  Navigating the approval process for you.  Dune Restoration:  Stabilising the site with sand, vegetation, and fencing plans.  Our team ensures your seawall not only protects your property but also integrates seamlessly with natural coastal processes , enhancing long-term resilience.    Ready to protect your beachfront property?   Contact ICM for tailored seawall solutions designed to safeguard your home and investment while meeting Gold Coast regulations.

  • Beree-Badalla Boardwalk Coastal Impact Assessment

    The Beree-Badalla Boardwalk, a 40-year-old elevated timber structure along Currumbin Creek, is set to be upgraded by the City of Gold Coast. ICM conducted a comprehensive Coastal Processes Impact Assessment to ensure the proposed design is resilient to erosion and inundation risks in this sensitive tidal nature reserve. Existing Beree-Badalla Boardwalk to be upgrade Project Details Client : Planit Consulting (for the City of Gold Coast) Date : 2022 Location : Currumbin Creek, Gold Coast, QLD About This Project The Challenge The Beree-Badalla Boardwalk, spanning 1.2km over the tidal nature reserve along Currumbin Creek, provides pedestrian access. After 40 years of service, the City of Gold Coast is planning to replace it with an upgraded structure. Situated within the Coastal Management District and an Erosion Prone Area, the project required a Coastal Processes Impact Assessment. The Solution ICM, engaged as sub-consultants by Planit Consulting, provided critical coastal engineering input to support the Development Application. The team undertook a thorough Coastal Processes Impact Assessment, which included: Data Review and Analysis : ICM reviewed available site data, including historic aerial imagery, surveys, previous reports, state mapping, geotechnical data and conducted a site inspection.

  • Seawalls in Australia: What you need to know

    Australia's diverse coastlines are subject to constant change due to natural processes and human activity. From erosion to rising sea levels, protecting coastal properties has become a critical concern for homeowners, developers, and businesses. Building seawalls in Australia can be part of the solution, however they are just one piece of the puzzle in coastal resilience puzzle. At International Coastal Management (ICM) , we specialise in guiding property owners, councils and developers through the complexities of coastal protection. From navigating local regulations to designing and implementing tailored solutions, we ensure your coastline is protected while balancing environmental sustainability. Understanding Coastal Protection in Australia Coastal management strategies in Australia vary across states and local councils, reflecting diverse approaches to addressing coastal erosion in the context of climate change. Some regions focus on “defend” strategies, such as building seawalls, restoring dune vegetation, implementing artificial reefs, or undertaking beach nourishment. Others may explore alternative strategies aimed at adapting to or mitigating the risks of erosion in vulnerable areas. These approaches are informed by ongoing research and the need to balance environmental, economic, and community priorities. If you are concerned about erosion affecting your coastal property, whether you’re in New South Wales, Queensland or beyond, the first step is understanding the specific regulations and requirements in your region. Engaging experts like ICM ensures you can navigate these complexities effectively and develop a solution that aligns with local policies. Are Seawalls the Right Solution? Seawalls are one method for protecting properties from erosion and wave action. Typically constructed from boulders, concrete, or other durable materials, they serve as a barrier to safeguard beachfront infrastructure. However, seawalls alone may not address the root causes of coastal erosion, and they come with their own set of advantages and disadvantages . At ICM, we approach coastal protection holistically, considering all three elements of the Coastal Resilience Framework : Top of Beach : Managing dunes and vegetation to stabilise the shoreline. Bottom of Beach : Enhancing nearshore zones to dissipate wave energy. Sediment Supply : Ensuring a balanced flow of sand to sustain beach health. By evaluating these factors, we ensure that a seawall in Australia is part of an integrated solution tailored to the specific needs of your site. Types of Seawalls Seawalls come in a variety of forms, with their design tailored to the specific needs of the coastline they protect. Materials can range from rock and boulders , which provide a natural and cost-effective barrier, to concrete and modular designs , often used for their durability and adaptability. Living seawalls  are an innovative option, incorporating features that can support marine life habitat while offering coastal protection. Geotextile container seawalls , made from durable fabric filled with sand or other materials, are a flexible alternative suitable for temporary or less-impacted areas. Seawalls also differ in shape, influencing their effectiveness and interaction with wave energy. Sloped seawalls  dissipate wave energy gradually, reducing impact forces, while vertical walls  reflect wave energy but may increase turbulence. Curved or stepped seawalls  are designed to deflect waves upward or break their energy in stages, offering additional protection while potentially enhancing aesthetics. The choice of seawall type depends on site-specific conditions, including wave dynamics, environmental considerations, and budgetary constraints. Enhancing Seawalls with Dunes and Living Elements In many cases, seawalls work best when combined with other coastal resilience measures. For example, Gold Coast seawalls incorporate vegetated dunes on top of them, to provide an additional layer of protection by helping to trap sand, reduce wind erosion, and absorb wave energy. Similarly, living elements like oyster reefs or seagrass beds can enhance biodiversity while contributing to coastal stability. Our team at ICM designs solutions that work with natural processes, creating sustainable outcomes that benefit both communities and the environment. How ICM Helps You Navigate Coastal Protection Coastal protection projects in Australia often involve complex approval processes and strict regulations. At ICM, we provide end-to-end support, including: Regulatory Guidance : Understanding and complying with local, state, and federal regulations. Permit Applications : Preparing and submitting all necessary documentation. Design and Engineering : Creating tailored solutions, including seawalls, dunes, and living elements.

  • About | Coastal Management

    Leading Coastal Resilience Since 1989 International Coastal Management was founded with a clear mission: to protect and enhance the world’s coastlines through innovative, sustainable solutions . Our story began in 1989, but the origins of our commitment to coastal resilience stretch back even further. Angus Jackson, our founder, witnessed firsthand the devastating effects of coastal erosion along the Gold Coast beaches after the 1967 and 1974 cyclone events. So, he began his career as a special projects engineer for the Gold Coast city in 1976 to improve the city’s resilience. With a limited budget, he grew the council’s resources, developing a coastal and waterways department that implemented world-first, iconic coastal resilience projects that helped “save the Gold Coast” (see more in the news clip). Recognising the unique success of the Gold Coast approach, Angus founded ICM, a coastal engineering company in Australia, to develop and implement similar resilience strategies around the globe, which has seen successful results in over 23 countries. Our team includes experts who are not just engineers and scientists, but also surfers, divers, lifeguards and environmental advocates. We are passionate professionals who care deeply about the work we do and the impact we have. This connection to the marine environment drives our dedication to protecting and enhancing the world’s coastlines and we are renowned for creating multi-beneficial project outcomes that not only reduce erosive impacts but also encourage ecological diversity and the user experience.
