Figure 9 - 1 in 100 year flood, Kempsey Urban Areas

This image is a zoomed in depiction of the Kempsey Urban Areas for the 1% Annual Exceedance Probability (AEP) of peak flood depths and levels, traditionally referred to as the 1 in 100 year flood event.

This image has the same significance as Figure 8 showing the whole study area.

The 1% AEP is a benchmark figure in flood terminology which is used to derive other flood control measures used in land use planning, such as the Flood Planning Levels and Flood Planning Area.

The Flood Planning Levels are a combination of the flood levels (1%AEP) and freeboards selected for floodplain risk management purposes.

The Flood Planning Area is an area subject to development controls, which for the Kempsey Study area is the 1% AEP plus .500m.
