Managing flood risk in your neighbourhood – Hawthorne Canal catchment

Share on Facebook Share on Twitter Share on Linkedin Email this link


Background

In 2015, Council engaged Council engaged consultants, WMA Water, to conduct a flood study. This involved modelling flood behaviour using rainfall data and information from the community about past storm events. The study determined where flood water will run, how the existing drainage system will cope and which properties are affected.

In 2017, WMA Water, has been engaged again – this time to undertake a flood management plan. This involves reviewing the flood study and identifying options for reducing flood risk in the catchment including:

  • better flood planning;
  • controls on development; and
  • new or upgraded stormwater systems.

What's happening now?

The recent review of the flood study identified properties in the catchment that are flood affected. This means that future development on properties that are flood affected may be subject to development controls.

Have your say

You are invited to provide feedback on the flood study and its findings by completing the submission form below.

Feedback closes on Friday 2 June 2017

Next steps

All submissions received through the public exhibition will be reviewed and considered by Council officers and WMA Water. Any changes resulting from this will be included in the updated Flood Planning Area map which will then be considered at a forthcoming Council meeting. Everyone who makes a submission will be notified of the outcome of the review of their property before the updated map is presented to Council.

Later in the year you will be invited to comment on possible options for reducing flood risk which will contribute to the plan for managing floods that is currently being developed.

Contact details

If you have any questions, please contact Ryan Hawken by phone on 9335 2246 or email.

This project is supported by the NSW Government’s Floodplain Management Program

    Tidal floods on Hawthorne Pde, Haberfield

There is a section of about 100m affected by these tides and we have already had one quite new car written off due to salt water damage.

    The area affected is around numbers 220–260 Hawthorne Parade and the last time this occurred was mid-January 2017. It occurs every high tide.

    The photo attached shows the depth of the water on 17 January 2017. The site says I can... Continue reading
