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 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.

    Council has engaged a consultant to undertake a Broughton Creek Flood Study for the township of Berry and its surrounding areas.

    This survey seeks to gather your personal experiences and local information on historical flood events to help us complete the updated Flood Study.

    Please provide your feedback by completing the Online Survey on this webpage by Sunday 19 November 2023.

    You can also complete the survey, in person, at the drop-in session on Thursday 9 November 2023 between 3:00pm – 6:30pm at the Berry School of Arts, where you can meet Council staff, local SES volunteers and our consultants working on this project.
