Floodplain Risk Management Plan

Lake Illawarra Floodplain Risk Management Plan

Lake Illawarra is a shallow coastal lagoon located on the undulating coastal plain between the ocean and the cliffs of the Illawarra Escarpment. The Lake catchment of approximately 23,500 hectares (excluding the Lake waterway area) is characterised by a low coastal plain, dominated by the western backdrop of the Illawarra Escarpment. The escarpment rises to a height in the catchment of 760m at Mount Murray, but more impressive is the slope of the escarpment, which rises over 400m over a horizontal distance of approximately 3km.

The objectives of floodplain management for Lake Illawarra are primarily to:

  • reduce the risk to life and limb;
  • reduce the risk to property and resulting reduction in losses;
  • minimise the disruption as a result of flooding;
  • ensure compatibility with ecological objectives identified through the Lake Management Process; and
  • ensure compatibility with objectives identified through the Stormwater Management Process.

This Plan seeks to ensure that these objectives are met in the implementation of the actions identified
