Challenges of Flood Plain Publication

Hansol Lee (Auckland Council)

A key outcome in many of the modelling projects completed by Auckland Council are production of flood plains. Auckland Council is required under the Local Government Official Information and Meetings Act (LGOIMA) to make available any information relating to hazards known to properties, which includes flood inundation, through Land Information Memoranda (LIM). Flood plains mapped from hydraulic modelling results for the 1%AEP event are used to represent flood inundation on LIMs.
