Project Overview

We are reviewing the Flood Study and Floodplain Risk Management Plan for the Middle Creek catchment.
This study will provide a better understanding of flooding in the catchment and how best to manage these flood risks into the future. The Middle Creek catchment encompasses the suburbs of Sawtell, Toormina and Boambee East.

This study will improve the accuracy and resolution of Councils existing flood mapping by making use of recently available high resolution topographic data in conjunction with best practice flood modelling software.

This mapping will be used to identify flood risks and possible flood mitigation options.

This mapping will be used to identify flood risks and possible flood mitigation options.

An online version of the final revised Flood Study and Floodplain Risk Management Plan documents for the Middle Creek catchment will be freely available to the public at the conclusion of the study.

Who is Responsible?

The study is being overseen by the Coffs Harbour City Council Floodplain Risk Management Committee and will include public consultation to ensure that the views of the community are properly considered.

The Committee consists of Councillors, Council Staff, State Emergency Service, State Government representatives and community representatives. BMT, an independent company specialising in flooding and floodplain risk management, will undertake the study. The NSW Department of Planning, Industry and Environment is providing financial and technical assistance.

Key Study Outputs

Floodplain Risk Management considers the consequences of flooding on the community and aims to develop appropriate floodplain management measures to minimise and mitigate the impact of flooding. This incorporates the existing flood risk associated with current development, and future flood risk associated with future development and changes in land use.

The outcomes of the review will improve the existing Floodplain Risk Management Study and Plan, and will contain an appropriate mix of management measures and strategies, to help direct and coordinate the responsibilities of Government and the community in undertaking immediate and future flood management works and initiatives.

Information from the study will be used by the State Emergency Service (SES) during flood emergencies and will be used by Council to manage development in flood-affected areas.

    CLOSED: This discussion has concluded.

    Council at its Ordinary meeting of Thursday the 23rd of September 2021 resolved to publicly exhibit the draft Middle Creek Flood Study, draft Middle Creek Floodplain Risk Management Study and Plan, the draft updated flood mapping datasets. and minor amendments to Coffs Harbour Development Control Plan (DCP) 2015.

    The draft Middle Creek Flood Study provides a new flood model for the Middle Creek catchment that incorporates advances in numerical modelling techniques and technology, updated topographic survey and rainfall data, and a major update to the national guideline for flood estimation (Australian Rainfall and Runoff). The draft Middle Creek Floodplain Risk Management Study and Plan provides a detailed assessment of the impact of flooding on the community and evaluates a range of management options to control or mitigate flood risk.

    As the new flood study and floodplain risk management study has redefined the 1% Annual Exceedance Probability (AEP), also known as the 100-year Annual Recurrence Interval (100 year ARI) flood extent and Flood Planning Area for the Middle Creek catchment, Council’s online flood mapping datasets need to be updated. The update to these datasets also includes some minor housekeeping updates to the 1% AEP (100 year ARI) flood extent, the Flood Planning Area and the Indicative Planning Area in other areas of the LGA to improve the accuracy of the mapping.

    As a consequence of the completion of the Middle Creek Flood Study, a minor amendment is also required to Part E4 Flooding of Coffs Harbour Development Control Plan (DCP) 2015.

    The exhibition period is from Thursday 30th of September 2021 to close of business Monday 1st of November 2021. All related information can be viewed in the document library on this web page.

    An online information session will be held on Thursday the 14th of October 2021 at 5pm. To sign up to the session please email simon.pierotti@chcc.nsw.gov.au
