Your use of this information is entirely at your own risk. You should independently verify the accuracy of any information before taking any action in reliance upon it.Read the full disclaimer here.A full description is available in the Metadata.Abstract:Minimum Fixed Floor Level map shows recommended relative levels within Kaiapoi and the Coastal Townships that should be used as minimum floor levels for natural hazard sensitive activities (buildings with one or more habitable rooms and/or contain one or more employees and/or a place of assembly).The Reduced Levels shown on the Minimum Fixed Floor Level map have been determined from delineating areas or basins within Kaiapoi and the Coastal Townships that have no natural overland flowpath. The RL for each area is calculated based on the 200 year flood level plus freeboard. RL, or \u2018reduced level\u2019 refers to identifying survey points with reference to a common assumed datum \u2013 in this situation the common datum is the New Zealand Vertical Datum 2016 (NZVD2016). An RL of \u201c2\u201d shown on the Minimum Fixed Floor Level map means that floor levels need to be built a minimum of 2m above this level.The freeboard used in each area varies from 300mm to 500mm and is dependent on the hazard due to flooding in each area.Update Frequency:As needed.Point of Contact:Waimakariri District Council.Lineage:Data was digitized using aerial imagery and LINZ parcel data.
