Why are you doing a staged approach?
To allow better information to be gathered and more detailed options to be considered. We want to ensure we engage with the community during the selection of the best option, to ensure a sustainable and affordable outcome. Future increases in flow and level caused by predicted climate change have been estimated. By using a staged approach, we can ensure that we have more long-term trends included in our data records. We are proposing to include an allowance in the early stages of the approach for raising stopbanks in the future as necessary.
How much is it likely to cost?
Given we are looking at a staged approach, the costs of flood protection improvements will be spread over a long-term period. Initial costs over the next two years are likely to be approximately $350,000. This cost will be for Stage 1: planning, engagement and data collection. Costs for future stages will be reassessed during Stage 1.
What’s wrong with the current stopbanks?
The condition of the stopbanks within the urban area require further investigation, we might not be able to rely on them to protect Masterton from flood waters. Preliminary investigations have indicated that the stopbanks are in poor condition. Some of the stopbanks around the urban area were built back in the mid-1900’s using material that may not have been suitable for the long-term integrity of the stopbanks.
I am the owner of a house in an area that looks to be directly impacted, what does it mean for me?
Please talk to GWRC about any site specific advice you may need. Note that the regulatory implications (e.g. new building levels) will be confirmed prior to final flood maps being produced.
