Floodplain Risk Management Study

Allans Creek Floodplain Risk Management Study (Revised)

The Allans Creek catchment has an area of 42 square kilometres. The catchment lies to the south west of the Wollongong CBD and rises up to the Illawarra escarpment. The catchment is characterised by steep upper slopes with little development and a floodplain with a mix of residential, commercial and industrial development. The objectives of this study are to:

  • implement a community consultation strategy, to ensure community input is obtained at key times throughout the study
  • describe and quantify flood issues in the Allans Creek catchment including an assessment of the likely cost of flooding to the community
  • identify and assess potential floodplain risk management measures to reduce the risks and hazards of flooding
  • review of issues relating to planning and development control within both the catchment and floodplain
  • review issues relating to emergency management within both the Allans Creek Floodplain and issues relating to adjacent floodplain areas, and
  • assess options on a common basis to outline the best measures to reduce flood risk based on environmental, social, economic, financial and engineering considerations.
