Flood Studies in Progress
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.
Haslams Creek Flood Study
2024 | Stage 1 - Information Gathering
For some time, Council has been working with residents of Wentworth Point and the Carter Street Precinct in an attempt to respond to known flooding issues, particularly along Hill Road.
In May 2024, the City of Parramatta received a $50 million grant (link to media release when it arrives) from the NSW Government to assist in the investigation and potential construction of drainage and other flood reduction infrastructure.
In late 2024, Council will launch the first stage in the NSW Government’s floodplain risk management process by asking residents to contribute photos, video and information about local flood events. This data collection is the first step to creating a flood model, which shows where flooding will occur, and a Floodplain Risk Management Study and Plan, which will suggest strategies to reduce flooding.
Due to the complex and interconnected nature of issues affecting Wentworth Point, the Haslams Creek Flood Study will feed into the existing Hill Road Masterplan. Council has received $8.5 million in funding from the Australian Government to assist in scoping and implementing improvements for Hill Road including addressing safety concerns at intersections and improving street lighting.

A’Becketts Creek Flood Study
2022 | Stage 1 - Information Gathering
In August and September 2022, the City of Parramatta Council began the first phase of its flood study work engaging with residents in Granville, Harris Park and Rosehill around local flooding linked to A’Becketts Creek. Residents shared photographs and videos and completed a survey providing detailed information on historical flooding in their neighbourhood.
Technical consultants are now using this information and other materials to build a draft flood model.
2024 | Stage 2 - Draft Flood Study
It is anticipated that the Draft A’Becketts Creek Flood Study will be on public exhibition in early 2025.
