Council has received funding from the NSW Government Floodplain Management Program, to undertake an updated Flood Study for the Broughton Creek catchment area. Assistance under the program is $2 from the Government for every $1 provided by Council.

The Broughton Creek Flood Study includes Berry and its surrounding areas within the Broughton Creek catchment area.

A Flood Study (2008) and Floodplain Risk Management Study and Plan (2012) for Broughton Creek was previously completed by Council. However, significant recent infrastructure upgrades such as the as the Transport for NSW Berry Bypass project, including a diversion of Town Creek to Bundewallah Creek upstream of Berry, and land developments in the area has triggered the need to update the existing flood study to better reflect current catchment conditions and associated flood risk. The Broughton Creek floodplain between the railway line and confluence with the Shoalhaven River was investigated as part of the Lower Shoalhaven River Flood Study (2022) and will not be included in this study.

This project is being undertaken in accordance with the NSW Flood Prone Land Policy, the NSW Flood Risk Management Manual (2023) and in close collaboration with the NSW State Emergency Services (SES), the NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW) , and other agencies and stakeholders as required.

Project Objectives

Council has engaged a consultant, Arcadis, to assist with the preparation of the updated Broughton Creek Flood Study. This study will improve Council’s understanding of flood behaviour and impacts on the community, and better inform management of flood risk in the study area across the full range of potential flood events from frequent to extreme. It will involve consideration of the local flood history, available collected flood data, and the development and calibration of hydrologic and hydraulic models utilising updated data and current best practice methodologies.

    The Draft Broughton Creek Flood Study is now on public exhibition until 9 November 2025.

    The study area comprises the township of Berry and its surrounding areas.

    The aim of the public exhibition and community consultation phase is for Council to seek feedback from the community via an online survey regarding the Draft Broughton Creek Flood Study so that these comments can be considered prior to finalisation of the study.

    The following documents can be viewed in the Document Library on this webpage:

    • A video presentation that discusses the study development and key outcomes.
    • A short Summary Report that outlines the study development and key outcomes.
    • Draft Broughton Creek Flood Study.
    • NSW State Emergency Service (SES) Rural Properties FloodSafe brochure which provides useful information on what to do when flooding is likely, how to stay informed during a flood event, flood evacuation information and contact details for emergency services.

    A community drop-in session will be held from 3pm to 6:30pm on Wednesday 29 October 2025 at the Berry School of Arts where the community can meet Council staff, local SES volunteers and consultants working on this project. There are no scheduled presentations, so the community can simply call in at a time that suits them to ask questions and provide feedback.

    Alternatively, should you have any questions on the draft study, or would like to provide further feedback via email, please contact the Floodplain Management Unit floodplain.management@shoalhaven.nsw.gov.au, or call Council on 1300 293 111.

    The Wollongong Coast, Shoalhaven and Clyde River flood warning improvement project is underway and the community is requested to provide feedback.

    The project is led by the NSW Department of Climate Change Energy the Environment and Water in consultation with the Bureau of Meteorology, NSW State Emergency Service, and in consultation with councils within the study area.

    The project scope includes consideration on a priority basis of upgrades to existing gauges, new gauges, and new flood warning service locations where these support the riverine flood warning network. It will also support community awareness of any changes to the flood warning service.

    Initial draft recommendations for improvements to the flood warning network have been developed in the Wollongong Coast, Shoalhaven and Clyde River valleys.

    The community is invited to provide feedback on these draft recommendations. Submissions close Sunday 20th April 2025

    The Berry township and surrounds experienced significant flooding over the weekend of 6 to 7 April 2024, following heavy local rainfall concentrated around the Illawarra escarpment.

    The flood models being developed as part of the updated Broughton Creek Flood Study are currently being calibrated to several historic flood events. This is an important part of a Flood Study to ensure that the models can accurately replicate real flood events and improve the confidence in the model results and Flood Study outputs.

    Council would like to obtain any photos and/or videos that the community have for the recent April 2024 flooding within the Berry township and surrounds that show the impacts of recent flooding. The key information being sought are photos and/or videos that capture the maximum flood level reached as indicated by a debris line or water mark on infrastructure such as fences, structures, buildings and bridges etc. Other critical information includes the location of the photo and/or video and the time that it was taken, such that Council can identify the location on a map.

    The community can share any photos and/or videos with Council by sending them to Floodplain.Management@shoalhaven.nsw.gov.au.

    Any information provided will be considered confidential and only be used for the Broughton Creek Flood Study.
