Floodplain Risk Management Study

Lansdowne Floodplain Risk Management Study

Lansdowne is located approximately 15 kilometres upstream along the Lansdowne River from the confluence of the Manning River. The Manning valley was first settled in the early nineteenth century and due to the importance of streams as transport routes for primary produce, numerous settlements were located adjacent to rivers below the tidal limit. In this way, the village of Lansdowne is located close to the tidal limit of the Lansdowne River, which is approximately two kilometres downstream from the railway bridge at Lansdowne.

This floodplain management study aims to generate, weigh and cost a set of options that will potentially address the different types of flood risk in the study area. The benefit of these management strategies will be ascertained by reference to the cost of doing nothing, that is, the long term cost of flooding to the wider community. The overall objective of this Floodplain Risk Management Study (FRMS) is to provide the mechanism by which an appropriate mix of management measures can be selected as part of a Floodplain Risk Management Plan to collectively mitigate or manage the flood risks. Flood Risk Management options are divided into the following categories:

  • Existing risk management
  • Future risk management
  • Continuing risk management
