Combined stormwater flooding results for WCC for a 100yr event including climate change and freeboard.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Intended Purpose: Wellington City Council and Wellington Water are working together to create an updated flood hazard map for Wellington catchments. The main purpose of a flood hazard map is to provide up-to-date information to the community. It takes into account sea level rise and increased rainfall caused by climate change and will help people better prepare for existing flood risks and avoid inappropriate building in floodplains. The flood hazard map gives you the opportunity to see what your suburb would look like in a once in 50-100 year flood. The flood hazard maps also appear in District Plans as flood hazard mapping, will be available on LIMs, and will be a key document in the consents process. Current flood plans are available through the Council website. They’ve been completed to best practice standards and have been peer-reviewed by an external independent party. Data created 2020, smoothing added 2025 Vertical Datum is 1953 , although only depth information is shown so the vertical datum is irrelevant.
