Wallis Lake Estuary Management Plan
Recommendations from the conservation strategy were employed in the CDS, however this will soon be replaced
by the biodiversity strategy that is currently being prepared. When this occurs it is recommended that the
conservation zones of the CDS be reviewed.
13.1.10 Forster/Tuncurry Floodplain Management Plan
The Forster/Tuncurry Floodplain Management Plan, finalised in 1998, provides the ‘basis for future management of
flood liable lands and the management of development within the Forster and Tuncurry floodplain areas’. Structural
(ie. levees and dredging) as well as non-structural (effective flood warning and evacuation systems) options were
investigated and evaluated for their effectiveness in reducing flood damages. Non-structural options were deemed
to be most cost-effective, and the following key measures were recommended:
• flood forecasting system
• preparation of a detailed evacuation plan
• flood awareness and public education
• voluntary house raising, and
• planning and development controls.
13.1.11 Wallamba River Floodplain risk management plan for Nabiac, Failford and
Minimbah areas
The Wallamba River floodplain risk management plan concentrates on extent of flooding from the Wallamba River
only and the risk to surrounding buildings where data is available. The document proposes methods of dealing with
existing, future and continuing flood risk. In summary, six prioritised actions were proposed:
• updating development controls to manage future flood risk
• flood planning, education, awareness and data collection to manage continuing flood risk
• timely review this floodplain risk management plan following completion of investigations into the
tributaries or at a maximum of 5 year intervals
• upgrading of access issues in key areas as identified in emergency management planning including
Willow Point Road at Failford and Glen Ora Road at Minimbah
• voluntary house raising to manage existing flood risk, and
• voluntary purchase to manage existing flood risk where dwellings cannot be raised.
13.1.12 Wallis Lake wetland management strategy
GLC aims to begin preparing a wetland management strategy in 2005 to addresses the recommendations made in
the wetlands action plan of the WLCMP. The anticipated goals of this plan will be to identify the wetland areas in
Wallis Lake, apply for RAMSAR listing of the wetlands under the international convention, and then implement best
practice management guidelines and management criteria under the RAMSAR convention to conserve and
enhance existing wetlands.
