Central Coast Council has prepared a draft Floodplain Risk Management Study and Plan (FRMSP) for the Davistown and Empire Bay catchments including the suburbs of Davistown, Empire Bay and portions of Bensville. The draft report was prepared following detailed analysis of the feedback we received from our first round of community consultation in 2019, and an assessment of potential flood risk management measures.
The draft reports were on public exhibition for a period of six weeks to obtain community feedback before the draft plan is finalised and adopted by Council. Submissions were accepted until Friday 26 March 2021.
This study is being prepared by specialist flood consultants Rhelm Pty Ltd and is jointly funded by Council and NSW Government Department of Planning, Industry and Environment (DPIE), through their Floodplain Management Program.
How to get involved
The community were invited to:
- review the draft study and plan: take a look at the draft report for the Davistown Empire Bay FRMSP online in the document library on the right of this page. A hardcopy of the draft report can be found at Kincumber Library.
- attend a community drop in session: Davistown information session on Wednesday 24 February, 4pm-7pm at Davistown Progress Association Hall and Empire Bay information session Thursday 25 February, 2pm-5pm at Empire Bay Progress Association Hall.
- register for a one-on-one online session: if you have a question and are unable to get to a community drop in, you could register to attend one of our online one-on-one meetings to discuss the draft reports with Council project officers.
- check out our interactive map: we've mapped out the recommended options from the draft study and plan, as well as flood extents for 1% Annual Exceedance Probability (AEP) floods on an interactive map.
- read our frequently asked questions: make sure you check out our frequently asked questions on our main floodplain management page to see if we haven't already answered your question!
- fill out the online submission form: if you have some feedback that you would formally like to provide Council on the draft study and plan, you could fill out our submission form, these will be evaluated before we finalise the document.
Submissions were accepted until 5pm Friday 26 March 2021 by:
- Email: FloodManagement@centralcoast.nsw.gov.au
- Post: PO Box 20, Wyong NSW 2259
- Our online submission form (now closed)

The Davistown and Empire Bay catchments lie adjacent to the Brisbane Water Estuary within the Central Coast Council Local Government Area. The catchments include the suburbs of Davistown, Empire Bay and a portion of Bensville.
The catchments are made up of residential, open space and bushland areas, as well as several key access roads.
Davistown and Empire Bay can be impacted by various types of flood risk including:
- local catchment flooding as a result of rainfall on the catchment,
- Brisbane Water flooding as a result of ocean storms and extreme tides
It is expected that all of these flood risks will be aggravated by the effect of climate change.
In December 2015, Council adopted the Brisbane Water Foreshore Floodplain Risk Management Study and Plan. Some of the recommended management options were deferred until further analysis was undertaken to assess the correlation between catchment flooding in the low-lying suburbs of Davistown and Empire Bay and resulting impacts of the recommended management options, if any.
The Davistown and Empire Bay Floodplain Risk Management Study identifies options to manage flooding (overland and coastal) and assesses them through flood modelling, economic damages assessments, and against a range of other environmental and social criteria. The findings of the Floodplain Risk Management Study form the recommendations and strategic program presented in the Davistown and Empire Bay Floodplain Risk Management Plan.
For this project, Council has previously undertaken community consultation to look at ways to manage the flooding problems that were identified in the Davistown and Empire Bay Flood Studies (Cardno Lawson Treloar, 2010).
Those who live, work or visit Davistown and Empire Bay catchments were invited to answer a questionnaire which was designed to provide Council with information on flooding problems they are aware of and suggestions on how they would like to see these problems addressed.
Two face to face information sessions were also held at Davistown and Empire Bay Progress Association halls in October 2019 to engage with the community on the flooding issues within the catchments and discuss some of the recommended flood management options.
E-newsletters have been sent out at various stages of the project to residents who have signed up for regular updates.
A draft of the Davistown and Empire Bay Floodplain Risk Management Study and Plan has now been finalised following detailed analysis of the feedback we received from our first round of community consultation in 2019, and an assessment of potential flood risk management measures.
