New Zealand - Hawke's Bay RCEP Coastal Hazard Zone 2 - Hawke's Bay Open Data

This dataset represents the location and extent of the inland boundary of ‘Coastal Hazard Zone 2’ (CHZ2) identified in the Hawke's Bay Regional Coastal Environment Plan 2013 (‘RCEP’). The RCEP has been prepared for the purposes of assisting the Hawke's Bay Regional Council with its roles and responsibilities under the Resource Management Act. Any party relying on this information for any other purpose does so at their own risk. The RCEP defines CHZ2 as “an area of land seaward of the CHZ2 boundary identified on the planning maps which is land assessed as being potentially at risk up to 2100 due to long term rates of coastal erosion and at some locations, may also include areas assessed as being potentially at risk of sea water inundation in a 1 in 50 year combined tide and storm surge event. It includes allowance for sea level rise, but does not include land within Coastal Hazard Zone 1 or Coastal Hazard Zone 3.”

The location and extent of CHZ1 in the RCEP was based on HBRC Report# 4043 - EMT 08/07. That report was prepared in response to evidence and submissions presented during hearings on the Proposed Regional Coastal Environment Plan's coastal hazard provisions. Those hearings were held between July 2007 and April 2008. That report was effectively a reassessment of erosion risk zones across the Hawke's Bay coastline. Consequently, the report presents reassessed extents of Current Erosion Risk Zones (CERZs) and 2100 Erosion Risk Zones (2100ERZs) at various locations within four territorial local authorities' boundaries. Previously, these CERZs and 2100ERZs were assessed as part of the 2004 Regional Coastal Hazard Assessment Study and subsequent 2005-06 studies on soft shore and cliff erosion hazard zones.
