Abstract: <\/SPAN><\/SPAN><\/P>

Areas potentially subject to flooding associated with a 200 year rainfall event or the breakout of the Ashley River/Rakahuri as defined in the District Plan Natural Hazards chapter. The non-urban flood overlay applies to those areas of land zoned rural and open space and recreation zones that are not located inside any residential zones or within water bodies. <\/SPAN><\/SPAN><\/P>

Flood modelling has been completed for all areas of the Waimakariri District with the exception of Lees Valley and flood exclusion zones (the flood exclusion zones are areas where the modelling has not been undertaken as these areas have recently had their land levels altered). Efforts have been made to update the Flood Modelling for new and proposed development areas, however the modelling may not be accurate in all areas where development has occurred since 2014.<\/SPAN><\/SPAN><\/P>

The Ashley River/Rakahuri breakout is flooding due to a stopbank breach on the Ashley River. These flood events include flow directly from a stopbank breach plus localised rainfall that would occur at the same time. This type of flooding is sometimes referred to as Fluvial Flooding. The Pluvial Flooding component of these scenarios was 10% of the Fluvial component (ie a 200 year breakout was modelled in conjunction with a 20 year localised rain event).<\/SPAN><\/SPAN><\/P>
