There are a range of other additional issues that relate to the Port Tarakohe Structure Plan.
Natural hazards:
Parts of the port and foreshore will be affected by sea level rise, coastal inundation and storm surges in the future. Modelling undertaken to date indicates this is relatively confined to the port itself and roading infrastructure.
Management approaches are likely to be available to address these issues in future and through implementation actions under other processes. This is an issue to be worked through as more is understood about these issues and as legislative reform progresses, however it needs to be considered in ensuring decisions for future change build in resilience.
Liquefaction:
This is possible for reclaimed areas of the port and foreshore but not an issue for the inland areas. Buildings can be designed to mitigate liquefaction risk and this needs to be considered in decision making.
Biosecurity:
There is a need to manage biosecurity risks through managing boats accessing the port and providing for secure cleaning facilities that do not discharge contaminants into the coastal waters. This is a significant issue in ensuring the safety of the Port for continued use to support marine farm operations and to protect biodiversity values.
Dredging:
This is required to maintain the harbour but there needs to be suitable locations for the dredged material to be disposed of safely and without affecting the environment. Dredging needs to be managed to ensure that the activity does not cause cumulative effects on biodiversity values.
Response to Issues
There are a range of responses that would address many of the issues identified in the Report.
