Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Coastal flood hazard zones were developed by 3 different external expert consultants in 2020. The layers are derived by advanced models using empirical calculations including tide gauge and extreme water level analysis, wind records and wave models, and used the 2019 LiDAR DEM. Three different models were used to construct the coastal flood layers: a full-coastline ‘bathtub model’ (Tonkin and Taylor, 2020), and two hydrodynamic models for Rangaunu (eCoast, 2020) and Kaipara (DHI, 2019) harbor. The reports detailing the methodologies can be accessed from the NRC website.Note:Old CFHZ 1 * Name of old CFHZ 1 in sde: CoastalFloodHazardZone1* The old CFHZ1 had incorrect values New CFHZ1 * Name of old CFHZ 1 in sde: CoastalFloodHazardZone1_August2023* The values were corrected and provided by Nicole Basher (Rivers and Natural Hazard Officer)
