Manly Lagoon Floodplain Risk Management Study and Plan

Thank you for your interest.  Engagement on this project has concluded.

We've developed a draft Floodplain Risk Management Study and Plan (FRMS&P) for the Manly Lagoon catchment to help reduce the impacts of flooding for residents and businesses.

The draft Study includes research into the social and economic impacts of flooding as well as what to do in an emergency. A number of floodplain management options to reduce flood risk in the catchment have been assessed.

Council is seeking your input on the draft Study and the preferred choice of management options.

  • Background

    7 months ago

    The Manly Lagoon Flood Study, 2013 updated the Manly Lagoon Flood Study, 1990 and confirmed the presence of flood risk within the catchment, particularly the lower catchment around Manly Lagoon. It also highlighted that in significant rainfall events particular areas such as those surrounding the lagoon, Warringah Mall and Balgowlah Industrial Estate, would be subject to high levels of flood risk.

    This Study will help improve Council’s management of flooding in the catchment, including selecting suitable ways to manage flooding for further investigation.
