Flood Resilience

Lismore has levees protecting the CBD and South Lismore. Both are designed for a 10% Average Exceedance Probability Event (previously known as a 1-in-10-year flood).

Since its completion in 2005, the levee system has only overtopped three times, in March 2017, and February and March 2022. Overtopping points are strategically positioned in order to minimise the impacts of fast flowing water on properties and infrastructure.

Lismore’s levee height and level of flood immunity was assessed in depth during the development and construction of the levee in the early 2000s. This is continually being assessed by Lismore Council in the Flood Plain Risk Management Plan.

This page offers an overview of projects in the ‘Flood Restoration Portfolio – Flood Resilience’ program, undertaken in response to the 2022 natural disaster.
