Floodplain Management Plans

Council is committed to sound Floodplain Management in accordance with the process outlined in the NSW Government’s 2005 Floodplain Development Manual (see Flowchart 1). To achieve this goal, catchment specific Natural Resources and Floodplain Management Committees as well as a technical Flood Steering Group meet on a regular basis in order to assist Council in the development and implementation of Floodplain Management Plans for catchments within the City’s boundaries.

Flowchart 1: Floodplain Management Process as set out in 2005 NSW Floodplain Development Manual.

Public Awareness Campaign

Raising public awareness of flood risk plays an important role in Floodplain Management.

Via the Floodplain Management Program, Shoalhaven City Council is progressively replacing historical flood information with data from detailed flood studies. The Public is encouraged to be actively involved in the process by contributing their own historical flood knowledge by either filling in questionnaires or attending public workshops for specific flood studies.

Public awareness of flood issues will also be broadened by disseminating information to the community via representatives of community groups who will be invited to attend a wide range of Natural Resources and Floodplain Management Committees. This will enable members of the public to contribute valuable information into the Floodplain Management Process via their elected representative as well as gain new knowledge from the representative’s reports back to their community groups.
