Combined stormwater flooding results for WCC for a 1yrARI event including climate change. Includes the following catchments: Owhiro Bay, Horokiwi, Haitaitai & Kilbirnie, Karori, Roseneath, Island Bay, Lyall Bay, Southern CBD, Tawa, Johnsonville, Khandallah, &MiramarPurpose: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 10 year flood and a once in 50-100 year flood.The flood hazard maps, once verified, will appear in District Plans, 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 DetailsVertical Datum: 1953 Wellington City Vertical Datum.Coordinate System: NZGD 2000 New Zealand Transverse MercatorSmoothed Flood Modelling Results categorised into the following depth bands:0.05 – 0.10 m0.10 – 0.25 m0.25 – 0.50 m0.50 – 1.00 m> 1.00mData TraceabilityGIS data published by: Modelling Team (Rebecca Buchanan) 17-06-2020Original smoothed layers created by: Jacobs (Keith Hastings)11-06-2020Modifications:08-07-2020: Added Khandallah and Miramar(Published Referenced map service on 3rd Feb 2021, Chrissy)For any questions please contact Wellington Water
