An interactive mapping information tool displaying the latest coastal hazards information developed under the Strategy is available through the Hawke's Bay Hazard Information Portal – click on the link.

Hazard Information Portal

How to use

To access coastal hazards information, select the link for ‘Coastal Hazards’ from the Hazards Portal home page. This will bring up a mapping tool. You will need to select ‘I Agree’ to start it.

Address Search - Using the Address Search box at the bottom of the screen you can type in a specific address, and the mapping tool will zoom in on that particular address, or simply zoom in to a part of the coast you are interested in.

Layers - You can then turn on various ‘layers’ of hazards information by selecting and de-selecting the hazards layers from the tool bar to the left of the screen.   The following layers can turned on and off in this way:

Coastal Erosion

Layers of probability (likely, possible, very unlikely and highly unlikely) that coastal erosion will affect land in the present day, at 2065 and at 2120.

Coastal Inundation

The extent of coastal inundation (flooding by sea water) possible in a 1% storm event (i.e. there is 1% chance of a storm of that magnitude happening every year) in the present day, at 2065 and at 2120.

Regional Coastal Environment Plan Hazard Zones
