Waikato District Council - Proposed District Plan (Stage 2 Natural Hazards), Notified 27 July 2020. This layer is a spatial representation of an overlay in the Proposed District Plan and indicates where land use will be regulated by various associated rules. It will be used as a guide in the regulatory process of implementing the Proposed District Plan and managing land use, subdivision, the environment and economy. This dataset is subject to changes undertaken through the Resource Management act. Note individual Proposed Plan rules can have different statuses, some may have current legal effect and others will not until the Proposed Plan becomes operative. Thisi data is provided for use in the District Plan only.
Coastal Sensitivity Area (Inundation) identifies land that is potentially vulnerable to coastal inundation over a 100 year period to 2120, assuming a sea level rise of 1.0 metre due to the projected effects of climate change. This belongs to the series of data relating to Natural Hazards which includes the following groups - coastal erosion, coastal inundation, inland flooding, and land subsidence. This layer belongs to the coastal inundation group. Use in conjunction with High Risk Coastal Hazard (Inundation) Area and Coastal Sensitivity Area (Open Coast).
METHODOLOGY: hand digitised. The extent of the hazard area was defined as area between shoreline and a set contour (see appendix A of appendix 5(h) for further details). SOURCE DATA: - Elevation data: Contour data sourced from any of the following: Waikato Regional Council - LiDAR 2010/2011, WDC Raglan Structure Plan, WRC LiDAR 2010 Raglan Harbour. - Shoreline data: Shoreline data was provided by provided by 4D Environmental Ltd on 21/08/2019 via email as a shapefile (NZTM2000 projection). The shapefile has been archived in ECM (document ID 2327334). The Shoreline used was the 2012 shoreline (source of shoreline was taken from 2012 WRAPS, which was prepared for WRC for use at 1:8,000 scale. In reality most of it was mapped at about 1:5,000.). A specific shoreline for Lorenzen Bay was also provided by 4D Environmental Ltd on 5/09/2019 via email as a shapefile (NZTM2000 projection) (archived in ECM (Document Set ID 2376525)).
