Service 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.
