FloodSmart Parramatta

Flood Big Ideas is big. Huge! Make sure you have your say

Flood Big Ideas is perhaps one of the biggest flood projects ever. Council’s investigating large-scale flood infrastructure that, if built, could reduce flooding in our City by up to 66cm.

There are three concept designs to review, one for North Rocks, Toongabbie, and the Parramatta CBD, with advantages and disadvantages for each.

They’re big ideas and they cost big bucks, but there are big benefits to. See our Flood Big Ideas project page and have your say before 5pm Friday 30 January 2026.
