A Coastal Hazard Risk Management and Adaptation Plan (CHRMAP) is a strategic plan used in Western Australia to manage and adapt to coastal hazards. These hazards can include things like erosion, storm surge, and sea-level rise, which are all expected to increase due to climate change.

CHRMAPs are developed by local governments in consultation with their communities and other stakeholders. They involve a process of identifying and assessing coastal hazards, evaluating the risks they pose, and developing strategies to manage and adapt to these risks.
