Why is this important?
For most people who live through a flood, normal life is put on hold. Homes and businesses are damaged. Services such as clean water and electricity use are disrupted.
In recent decades, significant floods occurred in Parramatta in 1986, 1988, 1991 and 2015. In the worst possible flood up to 20% of our areas could be covered in floodwaters.
The Parramatta CBD is the most flash flood affected major CBD in Australia, at worst case with only minutes warning of a forthcoming flood. This limits emergency response time and the ability to protect our homes and communities.
To help respond to the growing population and the limitations of our City environment, we need to increase our capacity to deal with flood events. By doing so we can create a more resilient community, one where our residents bounce back to normal life faster, at home and at work.
