Coastal infrastructure relocation is a planned adaptation method in which existing built assets in coastal zones—such as roads, utilities, housing, and critical facilities—are systematically decommissioned, dismantled, and reconstructed or re-sited in locations with reduced exposure to coastal hazards such as sea-level rise, storm surge, erosion, and flooding. Methodologically, it involves hazard and vulnerability assessment, cost–benefit and lifecycle analyses, stakeholder and land-use planning processes, and engineering design for new sites, often integrated with ecosystem-based approaches. It is typically evaluated within managed retreat strategies and requires governance instruments, regulatory frameworks, and phased implementation plans to minimize socio-economic disruption and maintain service continuity.
