Project updates
Feb 2026
Council continues to progress important flood management work across the Northern Beaches. Several Flood Studies and Flood Risk Management Plans are under way and/or programmed with the McCarrs Creek, Mona Vale and Bayview Floodplain Risk Management Study and Plan scheduled for public exhibition and adoption in the 2027/28 financial year.
Council has already completed the following work for McCarrs Creek, Mona Vale and Bayview:
- Stage 1: Flood information assessments and community consultation
- Stage 2: Risk assessment and emergency management arrangements
- Stage 3: Assessment of preferred flood risk management options
The remaining steps involve finalising the Draft Floodplain Risk Management Study, undertaking public exhibition and then presenting the Study and Plan to Council for adoption.
We are currently preparing the floodplain risk management study that will consider a range of flood management measures. A final suite of recommended options will be presented in the McCarrs Creek, Mona Vale and Bayview Floodplain Risk Management Plan.
Thanks to everyone who complete the survey. Responses will be provided to the consultant completing the study.
Further opportunities to comment on flood management options during the public exhibition of the draft study and plan later in the year.
We would like to get your thoughts and suggestions on flood management options to reduce flood risk and improve emergency response planning for the catchments of McCarrs Creek, Mona Vale & Bayview.
This short survey is your opportunity to contribute local knowledge to help with our future planning for the area.
Please complete the survey online.
Survey closes 16 June 2019.

Project background
Following the completion of the McCarrs Creek, Mona Vale and Bayview Flood Study project in 2017, Council commissioned engineering consultants BMT to complete a comprehensive Floodplain Risk Management Study for the McCarrs Creek, Mona Vale and Bayview catchments.
This study will consider a range of flood management measures, such as structural options (levees, detention basins etc.), emergency management improvements, community awareness activities and land use planning. The options will be assessed to understand the potential impacts and benefits, with a final suite of recommended options presented in the McCarrs Creek, Mona Vale and Bayview Floodplain Risk Management Plan.
This project is supported by the NSW Government’s Floodplain Management Program.
