Description: This data was received December 2018 from Tonkin and Taylor. The data has been simplified, tidied, and combined into one layer with additional fields added.
Description: Input DEM for plan change 27 flood modelling pre-dates the latest development in that area meaning the modelling needs to be re-run using a DEM that reflects the terrain post-development. The layer highlights those areas which need to be re-modelled.IMPORTANT! USE IN CONJUNCTION WITH: Vector.SDEADMIN.FloodRiskFloodPlainVector.SDEADMIN.FloodRiskOverlandFlowPathVector.SDEADMIN.FloodRiskFloodProneArea

Description: This data had previously been stored in 3 separate data layers and is now combined for simplicity and topological correctness. As before symbolising can be achieved by means of Representation RuleID but can also be the attribute type as listed below. All representations will be discontinued in the near future and their use should be discouraged.Flood plain based on a 1% AEP (100 year ARI) event and 2130 climate (RCP 8.5). TCC GIS team and water engineers created flood plains from flood prone and overland flow path polygons. MHWS is from LINZ LDS Coastline data layer. Data used in Plan Change 27.Flood prone based on a 1% AEP (100 year ARI) event and 2130 climate (RCP 8.5). Split into 2 categories: 100mm to 300mm flood depth, and greater than 300mm flood depth. TCC GIS team under supervision from water engineers converted raster areas to polygons, then smoothed. Data used in Plan Change 27.Overland flow path based on a 1% AEP (100 year ARI) event and 2130 climate (RCP 8.5). Split into 2 categories: major, and minor. TCC GIS team under supervision from water engineers converted raster area to polygons, smoothed, and connected disjointed overland flow paths together. Data used in Plan Change 27.Attributes used for classifying and symbolizing all have predefined domains.FloodRiskSource: The previous data layer, choices are.1 = FloodRiskOverlandFlowPath2 = FloodRiskFloodProneArea3 = FloodRiskFloodPlainFloodRiskClassification; The primary type for symbolising.Flood plainMajor overland flowMinor overland flowFlooding depth >300mmFlooding depth 100-300mmRuleID; FloodRiskCombined_Rep_Rules; the representation symbol type1 = Flood plain2 = Flooding depth 100-300mm3 = Flooding depth >300mm4 = Minor overland flow5 = Major overland flow-1 = Free Representation

Description: Updated in October 2023. The layer replaces previous tsunami evacuation zones with a single tsunami evacuation zone (blue zone). The blue zone marks the zone that people should evacuate from in a long or strong earthquake or when a tsunami warning is in place in the Bay of Plenty. The single (blue) zone replaces the previous three coloured zones (red, orange and yellow) to make it simpler for people to understand the evacuation zones (and maps).The new tsunami evacuation zone has been updated to align with LINZ High Water Spring, current aerial imagery and recent additional tsunami modelling undertaken for different sections of the coastline.The blue zone adjacent to the coastline within the Tauranga City Council boundary have been informed by modelling conducted by Tonkin + Taylor in 2013 and 2020. The remainder of the blue zone across the Bay of Plenty coastline has been informed by modelling conducted by GNS Science, eCoast and previous evacuation zones (based on the furthest inland extent).
