Summary
This study was commissioned by the Council to identify areas vulnerable to coastal erosion and coastal storm inundation around the coast of the district over the next 100 years and to provide broad management recommendations to assist with developing provisions for the present District Plan review. The coastal hazard study was conducted in two stages. A “first pass” assessment considered the entire coast of the District, to provide a high-level assessment of existing and potential future risk (including the effects of sea level rise) for a planning period of 100 years. A more detailed assessment was undertaken at priority areas (identified by the first pass). The coastal hazard assessment included a review of available published and unpublished data and three rounds of community consultation, involving well-attended workshops at key sites around the City. Further opportunity for community and stakeholder feedback will occur over coming months; with this draft report and maps provided on Council’s website for feedback. In addition, PCC propose to provide the proposed District Plan and maps for community feedback prior to formal notification.
