Hawkesbury Floodplain Risk Management Study and Plan
Under NSW legislation, Councils have the primary responsibility for management of development within floodplains. To appropriately manage development, Council needs a strategic plan which considers the potential flood risks and balances these against the beneficial use of the floodplain by development. To do this, Council needs to consider a range of environmental, social, economic, financial and engineering issues. This is what happens in a floodplain risk management study. The outcome of the study is the floodplain risk management plan.
On 11 December 2012 Council adopted the Hawkesbury Floodplain Risk Management Study and Plan, and resolved, in part, the following:
- Subject to any necessary minor editing and layout amendments the draft Hawkesbury Floodplain Risk Management Study and Plan, as exhibited, be adopted.
- The adopted Hawkesbury Floodplain Risk Management Study and Plan be published on Council’s website.
- Council notes that the adoption of the Hawkesbury Floodplain Risk Management Study and Plan does not adopt the changes to Council’s Planning Instruments. In this regard the review of the Planning Instruments will be via a separate statutory process that will further consider the recommendations in Volume two of the Plan, the recent changes to the planning Legislation and additional public consultation.
The study and plan consists of:
Introduction to the study area and NSW Government’s floodplain management process; review of existing data; explanation of flood mapping; risk to property; risk to life; options to mitigate existing flood risks; introduction to town planning issues; community consultation; draft floodplain risk management plan; frequently asked questions.
Explanation of NSW flood risk management framework; explanation of Environmental Planning and Assessment Act 1979 (the Act) flood risk management framework and guidelines; review of flood related development controls applying to the Hawkesbury; analysis of existing and projected population and development; discussion of planning issues and options; summary and conclusion; recommended amendments to Council’s Local Environmental Plan (LEP) and Development Control Plan (DCP).
Note whilst Volume 2 does contain recommended amendments to Council’s flood related development controls in the LEP and DCP and the exhibition of the draft Study and Plan will provide the community with an opportunity to comment on these recommendations, subsequent adoption of the draft Study and Plan will not in itself amend Council’s current development controls. If Council is to pursue amendments to the LEP and DCP this would require a separate process under the relevant provisions of the Act and associated Regulations, including an additional public exhibition process.
Flood extent, flood level and flood hazard categorisation maps for various flood events from the 1 in 5 year flood up to the Probable Maximum Flood; flood risk precinct map; annotated bibliography of the broad range of reports, studies and publications that the consultants have relied upon.
