Coastal Management Planning

The Shire of Denmark were experiencing significant erosion at Ocean Beach and Peaceful Bay and sought to prepare a Coastal Hazard Risk Management and Adaptation Plan to identify coastal risks and guide decision making in the near and long-term. 

The CHRMAP was prepared with a thorough assessment of coastal features, processes and hazards in the study areas, the vulnerability of assets in the study areas, and subsequent derivation of suitable management and adaptation options to ensure appropriate longevity of the vulnerable assets.

Inspections of Ocean Beach and Peaceful Bay sites were undertaken to identify hazards and risks. Coastal hazard allowances for the 10-, 50- and 100-year planning periods were defined using guidance outlined in State Planning Policy, and community consultation undertaken to determine social values of the coastal assets at risk and to inform concept planning for potential future coastal assets. Suitable adaptation pathways and options for highly valued assets were derived through risk assessment. A cost-benefit analysis was applied and implementation plans developed for the short term (10 year) and long term (100 year), considering current and future assets.

The CHRMAP was adopted by Council.
