The City of Greater Geelong completed a flood study that maps the flood extent for the Lara region. The flood extent indicates areas likely to be impacted by flooding in a large^ storm event.

The study itself has not increased the risk to properties of flooding. Rather, it has provided us with better information on the extent of overland flows in a large^ storm event.

We have contacted property owners in the Lara area to advise if their property has been designated as liable to flooding.

The flood extent only applies to the land and has not considered any buildings on the property. To understand if there is any risk of flooding to buildings, you may need to engage a surveyor to measure your floor levels.

We have created a fact sheet that provides general information on the City’s flood management and drainage systems along with information on the Lara Flood Study.

You can also read our frequently asked questions with key terms explained.

To find out more about the outcomes of the flood study please see the Summary Report.

^ Large refers to a 1% Annual Exceedance Probability (1% AEP) which means that a flood of this size has a 1% chance of occurring in any year.

A common misconception is that a 1-in-100 year event can take place only once every 100 years. However, it actually has a 1 in 100, or 1%, chance of occurring at any single location in any given year.

A better term is Annual Exceedance Probability (AEP). This refers to the probability that a flood event of a given magnitude will be equaled or exceeded in any one year. For example, a 1% AEP means the chance of a 1-in-100 year flood occurring this year, next year, or in any year is always 1 percent.
