About the Study and Plan

The North Byron Shire Floodplain Risk Management Study and Plan provide an overview of the current and future flood risks in the following catchments:

  • Brunswick River
  • Simpson's Creek
  • Marshall's Creek.

The overarching objective of the Plan and Study is to:

  • guide prioritising capital works projects
  • guide future planning in flood-affected parts of the Shire.

This information is important for residents and property owners in flood-prone areas of the Byron Shire, showing current and predicted flood levels which may be reflected in insurance premiums and property values. Importantly the information from the Study and Plan is designed to inform people and create awareness so we - Council and residents - can all be prepared for future rain events.

    The Floodplain Risk Management Plan sets out floodplain risk management measures into high, moderate and low priority actions for Council. This will be used to guide:

    • future capital works budgets
    • grant applications
    • mitigation and planning strategies.

    The Floodplain Risk Management Study is a detailed look at current flood management measures for

    • Simpson's Creek
    • Marshall's Creek
    • Brunswick River catchments.

    It includes towns such as:

    • Mullumbimby
    • South Golden Beach
    • Brunswick Heads
    • Billinudgel.

    It also takes into account the economic impact of flooding and future management measures such as:

    • flood zonings for properties
    • levees
    • hydraulic structures
    • channel maintenance
    • evacuation routes and centres.

    Community consultation

    Floods in 2017 resulting from ex-tropcial cyclone Debbie had a devastating impact on parts of the Byron Shire, especially Mullumibimby, Billinudgel, Ocean Shores, South Golden Beach and Brunswick Heads.

    In 2018 Council received $130,000 from the NSW Office of Environment and Heritage to do the North Byron Floodplain Risk Management Study and Plan with the aim of developing strategies and options to better manage the risk of floods in the future.

    Following consultation in 2018 and then again in in late January 2020, a revised Draft North Byron Shire Floodplain Risk Management Study and Plan are now on exhibition and we want to know what you think.
