Western Bay of Plenty District Council has been mapping and planning for natural hazards since the 1990s.

Council is continuing to review its natural hazard maps for the district and assessing how the risks from those natural hazards will be managed.

Council is working on this project with Bay of Plenty Regional Council and Tauranga City Council.

Council’s group manager policy, planning and regulatory services Rachael Davie says improving the accuracy of hazard maps is more critical than ever due to the increasing legislative requirements around climate change, reducing natural hazard risk and ensuring preparedness and the ability to respond to natural disasters.

“The mapping information will help people make informed decisions about undertaking building works, buying property or preparing for a natural disaster.

“As we complete the mapping of each hazard, we will notify landowners and put the information on council’s website, on property files and in any land information memoranda requested for properties,” says Rachael.

Council will also use the maps when processing resource consents, project information memoranda and the building consents to ensure that the risk from natural hazards to people and buildings is assessed.

Mapping of all natural hazards may take around five years due to the district’s size and geographical diversity.

Hazards being investigated include:

Flooding

Coastal inundation

Coastal erosion

Land instability

Liquefaction

Tsunami

Active faults

Volcanic hazards.

The latest mapping available is for:

Coastal inundation along the Tauranga Harbour.

Flooding at Omokoroa.

Flooding at Katikati.

Council has sent letters to the owners of approximately 3500 properties within those areas identified as being potentially susceptible.

The new information is included on councils Natural Hazards web page.

This information improves understanding of how the expected effects of climate change many influence what coastal inundation and flooding looks like in the future. These studies forecast to 2130 and will allow council to prepare and plan for what’s ahead.

Council is also in the process of mapping other natural hazards and this information is anticipated to be available mid to late next year:

Tsunami along the Tauranga Harbour.

Tsunami at Waihi Beach, Athenree and Bowentown.

District wide liquefaction.

The remainder of natural hazard maps for the district will be completed over the coming years.

Council’s web page has an updated list of Mapping Projects and Timeframes to keep people informed of what’s happening.

Floods, tsunamis and coastal erosion give these nouns new meaning !!
