Building height data was digitised at the elevation of each rool eave. Pergolas, desck and other such structures attached to buildings were not captured. The highest point of each building roof collected is shown as a data point located along the ridge of the highest elevation. Upon completed of the data capture, checks were carried out to ensure the topology was clean and seamless.All spatial data for this project provided in terms of New Zealand Trasverse Mercator 2000 map projection (NZTM2000). The datum is New Zealand Geodetic Datum 2000 (NZGD2000). The height datum is orthometric Lyttleton 1937 (sea level).Update Frequency:As needed.Point of Contact:Waimakariri District Council.Lineage:Data was digitized using aerial imagery and LINZ parcel data.

The RL for each area is calculated based on the 200 year flood level plus freeboard. RL, or ‘reduced level’ refers to identifying survey points with reference to a common assumed datum – in this situation the common datum is the New Zealand Vertical Datum 2016 (NZVD2016). An RL of “2” 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.

Areas of well-defined and distributed deformation have a 20 m buffer applied as per the Ministry for the Environment guidelines. Areas of uncertain and extended deformation were considered by the report authors to not have been mapped precisely enough to warrant assigning a 20 metre buffer. The joins between the well-defined and distributed deformation (with 20 m buffer) and the uncertain and extended deformation (without 20 m buffer) have been manually adjusted slightly to smooth out any sharp edges. The well-defined and distributed deformation areas (with 20 m buffer) have also been clipped out of adjacent uncertain or extended deformation areas.'Feature' is the type of ground deformation present.'FAZ_class' is the category of fault complexity, set out in Table 2 of the accompanying report, and following the MfE active fault guidelines.'NAME' is the fault or other landform unit that the deformation is associated with.'BUFF_DIST' is the width of the added buffer (20 m on well-defined or distributed deformation, 0 m on uncertain and extended deformation). Update Frequency:As needed.Point of Contact:Waimakariri District Council.Lineage:The data were captured at a scale of 1:5,000 to 1:10,000. Accuracy may vary.

GNS Science Consultancy Report 2014/211. See this report, and the metadata for the Canterbury fault awareness areas 2019 dataset, for more detail on how the fault awareness areas were delineated.The fault awareness areas show areas where there may be a surface fault rupture hazard. Surface fault rupture is the permanent breaking, ripping, buckling or warping of the ground on or near the line where a fault meets the ground surface, as a result of movement on the fault. It is different from earthquake shaking.The suggested Waimakariri fault hazard (important infrastructure or facilities) overlay is where the fault rupture hazard should be specifically considered and the fault rupture deformation areas mapped as part of a consent for important or critical infrastructure or facilities (as defined in the Waimakariri District Plan).Descriptions of the attribute fields:Name: Fault name, taken from the district fault name field (e.g. WDC_name) in the district fault datasets. Some of these have been changed from the original district fault names to make them consistent with what is given in the district fault report.Zone:Fault zone that the fault is within, if any.Certainty:The level of confidence that the mapped feature is in fact an active earthquake fault - definite, likely or possible. See Barrell, et al, 2015 for full descriptions.Surface form:How clearly the mapped feature can be seen at the ground surface - well expressed, moderately expressed, not expressed or unknown. See Barrell, et al, 2015 for full descriptions.Min RI:Minimum fault recurrence interval, taken from the summary table of each district fault report.Max RI:Maximum fault recurrence interval, taken from the summary table of each district fault report.Min RI Class:Minimum fault recurrence interval class (as defined in Kerr, et al, 2003, Guidelines for development of land on or close to active faults), taken from the summary table of each district fault report. Some values have been changed to better match the minimum fault recurrene interval.Max RI Class:Maximum fault recurrence interval class (as defined in Kerr, et al 2003, Guidelines for development of land on or close to active faults), taken from the summary table of each district fault report. Type:Whether the mapped feature is a fault (fault reaches the ground surface) or a monocline (fault stops below the ground surface but forms a fold in the ground surface).Buffer m:Whether a 125m or 250m buffer has been applied to the fault to create the fault awareness area as per Barrell, et al, 2015.Other technical fields, such accuracy, sense of movement, dip direction, down quadrant, trendandfacing, as well as territorial authority (all Waimakariri) have been removed for simplicity but this information can be found in the Canterbury fault awareness areas 2019 dataset.Update Frequency:As required.Point of Contact:Waimakariri District Council

GNS Science Consultancy Report 2014/211. It also includes small lengths of definite (not expressed) and likely (not expressed) fault awareness area where they link two definite (well-expressed or moderately-expressed) or likely (well-expressed or moderately-expressed) fault awareness areas, as the fault rupture hazard should still be considered in these areas during subdivision.These small lengths of definite (not expressed) and likely (not expressed) fault awareness area have had their width reduced to be the same as the definite (well-expressed or moderately-expressed) and likely (well-expressed or moderately-expressed) fault awareness areas on either side (total width 250 metres) as it is unlikely that the actual location of the fault trace deviates from the adjacent definite (well-expressed or moderately-expressed) and likely (well-expressed or moderately-expressed) fault awareness areas.
