Rural Flood Modelling Extent 2021

The Rural Stormwater Flood Modelling 1% AEP’ map shows the extent of flooding in an extreme 1-in-100-year rainfall event, which has a 1% probability of occurring in any given year. This means on average this event occurs once in one hundred years. The flood mapping extents include shallow flooding and low hazard water depths. The Rural Stormwater Flood Modelling 1% AEP’ map shows the extent of flooding in an extreme 1-in-100-year rainfall event, which has a 1% probability of occurring in any given year. This means on average this event occurs once in one hundred years. The flood mapping extents include shallow flooding and low hazard water depths. This modelling has a number of limitations, including: a) The modelling only provides a high-level indication of where rainfall may pond primarily due to ground contour. It is based on what culverts and drains were known to Council at the time of modelling. It does not account for any private culverts or drains not known to Council at the time. Given this, where such assets are physically present the indicated flood extents will likely be inaccurate as the water can flow elsewhere. b) The modelling has not been sensitivity tested or validated against actual flood events. c) The mapping is not suitable for indentification of dwelling flood risk or for setting finished floor leves for any development. d) The flooding extent shown uses the ground levels in 2021. Any changes to ground levels since this date (such as through development and earthworks) are not represented.
