ICM designed an artificial surf reef on Colombia’s north coast to create beginner and intermediate surfable waves while maintaining swimmer safety and everyday beach use. The concept balanced wave performance, geomorphology, access, and hazards, and was tailored to the local budget and resources. Project Details Client: Private client Location: Colombia Date: 2023 About This Project The Challenge A growing tourism destination sought consistent learn-to-surf conditions without compromising nearshore processes or public access. The solution needed to match the dominant swell direction, local sediment dynamics, and practical construction methods suitable for a remote coastal setting. The Solution ICM assessed multiple reef typologies and materials, then selected a layout to lengthen rides and limit cross-currents. Numerical modelling was performed with CMS-Wave, CMS-Flow, and SBEACH. The design targeted ride times greater than 10 seconds in typical conditions while maintaining safe conditions inside the reef footprint and preserving daily beach use. "Our aim was simple: longer, cleaner rides for beginners and intermediates, with a design that fits the site and the budget." - Aaron Salyer, ICM Services Provided Concept development and option testing Numerical modelling Schematic and detailed design reports Technical drawings and BOQ

Living Speed Bumps is a hybrid sand-retention approach that stabilises beaches by slowing and guiding natural sediment transport, rather than blocking it. The concept combines two compact, rounded headlands with an offshore artificial reef and targeted nourishment to influence wave breaking, nearshore currents and sand pathways, with the aim of retaining sand in the compartment longer while maintaining beach access, amenity and a natural-looking shoreline. The “living” component is delivered through ecological features integrated into the reef and shoreline elements, supporting habitat complexity alongside beach resilience. ICM’s Living Speed Bumps concept was selected through the City of Oceanside’s RE:BEACH international design competition . ICM is now working with GHD to progress the pilot through detailed design and engineering, including technical refinement and testing as the project advances toward implementation. Project Details Client: City of Oceanside (RE:BEACH Program)  Design Partner: GHD  Location: Oceanside, California, USA  Status: Detailed design and engineering phase  About This Project The Challenge Oceanside has experienced chronic erosion and reduced beach width, affecting public access, amenity and coastal resilience. The City initiated RE:BEACH to identify a sand-retention pilot that could support a wider, more stable beach while remaining compatible with community values and coastal use.  The Solution The selected Living Speed Bumps pilot focuses on a paired headland and reef system supported by nourishment, intended to slow erosive forces and moderate sediment transport so sand persists longer within the pilot compartment. The current phase includes detailed design development and engineering refinement, with physical wave modelling being used by the City to test performance of the proposed reef and headland system across a range of tide and wave conditions.  Services Provided Detailed design and engineering development Coastal processes and erosion assessment to support design refinement  Design input to physical wave modelling and performance testing framework  Ongoing support to progress the pilot through the design and approvals pathway Interested to know more?

ICM in partnership with Griffith University supported the City of Joondalup to review and document alternative coastal adaptation options for the City’s coastline. The work assembled and synthesised existing plans, datasets and prior management actions, then set out a clear, decision-ready long list of measures to inform the Draft Coastal Hazard Risk Management and Adaptation Plan (CHRMAP). Project Details Client: City of Joondalup Partner: Griffith University Location: Western Australia, Australia Date: 2026 About This Project The Challenge Joondalup’s coastline is an open, sandy, micro-tidal, high-energy environment experiencing chronic erosion pressures, with important assets and community values concentrated along the foreshore. The City required an evidence-based review of adaptation measures that could suit local conditions, align with existing planning, and be screened for feasibility before progressing to more detailed assessment and implementation planning. The Solution ICM and Griffith University completed a comprehensive review of relevant reports, coastal data and existing management frameworks, supported by a targeted literature review of global best practice and comparable settings. Adaptation measures were structured into practical categories, including sand management approaches, submerged or low-crest structures, emerged hard structures, and hybrid or innovative alternatives. For each option, we documented the intended function, typical applications, key design considerations and constraints, and implications for Joondalup, and identified options that were not suitable or were outside the project scope. The outcome was an options long list aligned with the Draft CHRMAP structure, providing a clear basis for subsequent multi-criteria and cost-benefit assessment, community discussion and staged delivery. The report will provide council and stakeholders clear options for ongoing development. Services Provided Desktop review of existing plans, reports and available coastal datasets Literature review of global practice and comparable coastal environments Development of a structured list of adaptation measures suited to local conditions Documentation of design considerations, constraints and implications for implementation Identification of out-of-scope and unsuitable options Preparation of a preliminary options long list aligned with the Draft CHRMAP Have a project in mind?
