Description: River Flood Hazard Zones The 10 year river flood extent, the area potentially susceptible to river flooding in a 10% AEP / 10 year ARI, for the Ruawai catchment developed by Water Technology in 2024.The 50 year river flood extent, the area potentially susceptible to river flooding in a 2% AEP / 50 year ARI, for the Ruawai catchment developed by Water Technology in 2024.The 100 year + CC (climate change) river flood extent, the area potentially susceptible to river flooding in a 1% AEP +CC / 100 year ARI + CC, for the Ruawai catchment developed by Water Technology in 2024.Coastal Flood Hazard Zones Coastal Flood Hazard Zone 0 (Current), the area potentially susceptible to coastal flooding in a 1% AEP, for the Ruawai catchment developed by Water Technology in 2024.Coastal Flood Hazard Zone 1 (50 years), the area potentially susceptible to coastal flooding in a 2% AEP + 0.6 m SLR, for the Ruawai catchment developed by Water Technology in 2024.Coastal Flood Hazard Zone 2 (100 years), the area potentially susceptible to coastal flooding in a 1% AEP + 1.2 m SLR, for the Ruawai catchment developed by Water Technology in 2024.Coastal Flood Hazard Zone 3 (100 years + Rapid Sea Level Rise Scenario), the area potentially susceptible to coastal flooding in a 1% AEP + 1.66 m SLR, for the Ruawai catchment developed by Water Technology in 2024.Note: This layer has been added to AGOL and is used in the Natural Hazard Viewer Data provided by: Nicole Basher (Rivers and Natural Hazards)              Data Published by: Divya                 Published on: Feb 2025
