Parent Layer: Coastal Inundation Overlay

Name: Existing coastal inundation extent with a 1:100 year storm (High Hazard Area)

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: INTENDED PURPOSE: Polygon dataset of areas affected by the Coastal Inundation Hazard Overlay (part of the Coastal Hazard Overlay) created for the Wellington City Council District Plan as part of the District Plan Review Process. ABBREVIATIONS/ACRONYMS: DP - District Plan; ePlan - "Electronic Plan" the web version of the District Plan. REFRESH RATE (Data only): Static. OWNERSHIP: This data is owned by WCC District Planning Team, contact District.Plan@wcc.govt.nz for questions about this layer and its appropriate use cases. Ownership specifies legal or administrative control over the content. STEWARDSHIP: This data is maintained by WCC City Insights Team, contact cityinsightsgis@wcc.govt.nz for information about the creation of this layer and its maintenance. CUSTODIANSHIP: This data is maintained by WCC City Insights Team, contact cityinsightsgis@wcc.govt.nz for information about the creation of this layer and its maintenance. Stewardship addresses the ongoing care, maintenance, and management of the content. AUTHORATATIVE DATA SOURCES (Data only): NIWA undertook a coastal hazard and sea level rise assessment (Allis et. al. 2021) for the Proposed District Plan. Further data changes were made as part of the District Plan Review Process. SUMMARY OF DATA COLLECTION (Data only): The assessment included delineation of the inundation hazard areas within Wellington Harbour, Mākara, and the South Coast of Wellington. 0.05m was considered be the limit of acceptable nuisance flooding that could be managed by existing stormwater controls. Water depths of less than 0.05m were removed from Allis et. al. 2021 modelled data, and the output raster data smoothed to create the Coastal Inundation Hazard Overlay. All post-processing of raster data layers is consistent with methodology used for the WCC District Plan.
