Coastal Erosion

Gisborne areas susceptible to coastal erosion, coastal flooding and/or tsunami (ASCE) layer as identified in a 2015 study commissioned by the Gisborne District Council.

The Gisborne District coastline extends some 500 km from Takararoa in the south to Omaruparoa in the North and comprises some 138 km of sandy and gravel beaches and 202 km of cliffed coastline. An Area Sensitive to Coastal Hazards (ASCH) line was developed by Gibb between 1994 and 1999 and shows areas that may be adversely affected by coastal erosion, coastal flooding and/or tsunami. The line is applied to areas where more comprehensive and locally specific Coastal Erosion Hazard Assessment have not been undertaken and indicates where prospective developers may be required to undertake further research on coastal hazards. New research is being undertaken on effects of tsunami and coastal flooding in the Gisborne District that will replace those components of the ASCH
