Clifton to Tangoio Coastal Hazard Strategy 2120

HB Coast

Strategy Development

What is the Strategy about?

The Strategy will provide a long term framework for managing the coast between Clifton and Tangoio.

The long term vision for the Strategy is that “Coastal communities, businesses and critical infrastructure from Tangoio to Clifton are resilient to the effects of coastal hazards”.

This strategy will provide a framework for assessing coastal hazards risks and identifying options for the management of those risks for the next 100 years from now to 2120.

It is being developed collaboratively by Hastings District Council, Hawke’s Bay Regional Council, Napier City Council, and groups representing mana whenua and tangata whenua through a joint committee.

Why do we need a strategy?

The New Zealand Coastal Policy Statement requires Local Authorities to consider and plan for coastal hazards risks. Under Policy 24 (1), Local Authorities are required to:

“Identify areas in the coastal environment that are potentially affected by coastal hazards (including tsunami), giving priority to the identification of areas at high risk of being affected. Hazard risks, over at least 100 years, are to be assessed…”

In her 2014 report, the Parliamentary Commissioner for the Environment (PCE) stated that over the past century the average global sea level has risen by about 20 cm.  The Intergovernmental Panel on Climate Change (IPCC) expects sea level to rise up to a metre by the end of the century, and that about 70% of the coastlines worldwide are projected to experience sea level change within ±20% of the global mean; and it is very likely that there will be a significant increase in the occurrence of sea level extremes in some regions by 2100.

The Strategy represents a cross-council approach to identifying and responding to these hazards. It provides a platform for making decisions about the most appropriate responses.

Strategy Scope

  • Assesses coastal hazards risks between Clifton and Tangoio associated with the following processes occurring over the period up to 2120:
    1. Coastal erosion (storm cut, trends, effects of sea level rise);
    2. Storm surge inundation (wave set-up, run-up, overtopping and sea level rise);
    3. Tsunami.
  • Develop a model for funding responses to coastal hazards risks.
  • Provide a decision-making framework to identify, evaluate, consult on and select practicable adaptation options that respond to the identified coastal hazards risks.
  • Implement the selected adaptation option(s) in a coordinated and planned manner that will provide the best overall outcome for the Hawke’s Bay community.
