Coastal Flooding Risk Mitigation Plan
Environment Waikato’s Coastal Flooding Risk Mitigation Plan sets out efficient and effective flood risk management for the coastal marine areas of the Waikato Region. Coastal flooding management aims to prevent floods from happening, or lessen their effects by planning for response and recovery. Risk mitigation plans define the roles of Environment Waikato, district councils, and the community in managing the impacts of potential natural hazard events. 
Coastal flooding is a natural hazard in the Waikato Region, mainly affecting low lying areas around the Firth of Thames, some eastern Coromandel Peninsula settlements, and flood plains in the Hauraki District. Coastal flooding hazard problems in the Waikato Region generally occur as a result of human use and occupation of naturally flood-prone areas. All significant coastal flooding events also have potential to threaten human life and safety.
Environment Waikato’s Coastal Flooding Risk Mitigation Plan aims to achieve efficient and effective coastal flooding risk management through:
- clarifiying the coastal flooding management roles and responsibilities of various agencies
- dealing with the adverse effects of coastal flooding and the management options for minimising them
- planning for response, recovery, monitoring and review activities.
