AUCKLAND COUNCIL’S PROGRESS ON SUSTAINABLE SHORELINE ADAPTATION PLANS

Abstract

Auckland Council is currently developing shoreline adaptation plans across the Auckland region to support the sustainable management of public assets into the future with increasing coastal hazard risks. These build upon the Coastal Management Framework (Carpenter et al. 2017) and are being developed as 20 phased plans. At the time of writing the ‘Whangaparāoa’ and ‘Beachlands and East’ Shoreline Adaptation Plans (SAP) have been completed. The ‘Āwhitu Peninsula’ and ‘Manukau South’ SAPs are well underway, and the remaining SAPs are programmed to be completed over the next 4 years. To inform the development of the adaptation strategies numerous datasets were required. Coastal erosion and coastal flooding predictions have been mapped for the Auckland region to assess the evolving coastal hazards. Up-to-date coastal asset information was gathered through hundreds of coastal asset inspections for each SAP area. This asset data fed into adaptation strategy decisions as well as being incorporated into a regional risk assessment to assess the relative risk across Auckland’s SAP units.
