Lithgow Floodplain Risk Management Study and Plan
Lithgow City Council has engaged consultants to undertake the Lithgow Floodplain Risk Management Study and Plan. The purpose of the study is to assist Council in refining strategic plans for mitigating and managing the effects of existing flood risk (associated with existing development on flood prone land), future flood risk (associated with any new development on flood prone land) and continuing flood risk (the risk remaining in both existing and future development areas after floodplain risk management measures are implemented) in the Farmers Creek and Marrangaroo Creek catchments at Lithgow.
The study is jointly funded by Council and the NSW Department of Planning, Industry and Environment and aims to build community resilience towards flooding through informing better planning of development, emergency management and community awareness. Council has established a Floodplain Risk Management Committee which is comprised of relevant council members, state government agencies and community representatives.
The study will build on the results of the recently completed Lithgow Flood Study Review which was completed in 2017 and will reassess the measures which were recommended as part of the Lithgow Floodplain Management Plan which was prepared in 1991.Figure 1 attached shows the indicative extent of the 1 in 100 year flood in the Farmers Creek and Marrangaroo Creek catchments, as well as the extent of flood prone land (as defined by the extent of the Probable Maximum Flood) under present day climatic conditions.
A copy of the Lithgow Flood Study Review in addition to other floodplain management information, including an FAQ, can be found on Council’s website at http://council.lithgow.com/lithgow-floodplain-management/
An important first step in the study is to appraise what flood related issues are important to the community. A questionnaire has been developed by our consultant to gather this important information from local residents and businesses. All information gathered in the questionnaire will remain confidential and will be for use in this study only. Council would like to sincerely thank all community members who take the time to complete the questionnaire.
The questionnaire for this study will be closed at 5pm on the 28th August 2020.
Note: Members of the public may have already received this questionnaire by mail as their properties have been identified as being within the Interim Flood Planning Area (See Figure 6.16 of the Lithgow Flood Study Review) or land subject to overland flow deeper than 100mm. The Interim Flood Planning Area for the purposes of the Flood Study Review was set equal to the peak 100 year Annual Recurrence Interval – a 1 in 100 year flood event – plus 500mm for freeboard
