We now have around 2600 properties in our categorisation programme, after receiving almost 500 new signups since the start of the year. The programme is about understanding the risk to life from future weather events, so we are still encouraging at-risk homeowners to opt-in to this limited scheme.

Categorisations progress

As at 8 March, over 2300 desktop and 1500 on-site assessments have been completed, providing a good foundation for our risk assessments.

So far, the number of properties within each category is in line with what we expected with 729 confirmed, including the majority of homes being Category 1 – indicating no intolerable risk to life. More categorisations are being confirmed on a daily basis. With the buyout process in full swing, we are looking to start deconstruction on the first handful of homes at the end of the month.

Given limited access to much-needed engineering experts, we are borrowing from other regions, and from Australia. We are now working with 25 companies with over 70 skilled geotechnical and flooding experts dedicated to this categorisation work across the region.

Complex cases

Many properties are proving more complex to categorise for several reasons:

  • There is an intolerable risk to life, but we need to assess the feasibility of a mitigation at the property. Examples include retaining walls, house raising or moving, altering fences and other structures blocking overland flow paths, or changes to driveways or landscaping
  • There is an intolerable risk to life, but we are waiting on confirmation of a community infrastructure project that could reduce this risk for whole neighbourhoods. Examples include redirecting overland flow paths, making more space for water to flow and pool, stopbanks, and upgrading culverts and roads. These projects are being scoped looking at feasibility of timelines, practicality, costs and impacts
  • There are both flooding and landslip issues at the property
  • Recent work at neighbouring properties, or the shifting of land, have changed the risk profile since we started.

We expect many of these more complex categorisation to be confirmed mid-year for those that had opted in by the end of 2023.
