Planning for Climate Change in Dora CreekA community update from the Dora Creek Catchment Group – December 2008
Planning for Climate Change in Dora CreekA community update from the Dora Creek Catchment Group – December 2008
<< Dora Street residents and Council staff at the Climate Change Adaptation workshop. L-R: Laurene Mulcahy, Graham Clarke, John Mulcahy, Neale Farmer (LMCC), and Kim Webb.
In September about 50 Dora Creek residents held a workshop on the effects of climate change. They heard the latest scientific information, how sea level rise and storms may affect the lake and creek, and what policies are being considered to help prevent and adapt to climate change. The workshop agreed to develop and help implement a community “Climate Change Adaptation Plan” for Dora Creek over the next few years.
What the scientists are saying• The atmosphere and ocean are getting warmer as a result of the
greenhouse effect • The warm water expands, causing sea level rise• Even if global carbon dioxide emissions are controlled, average global sea
levels are predicted to rise by between 0.18 metres and 0.59 metres by 2100• Studies by the CSIRO show local factors such as the East Australian Current
may raise the ocean here by up to 0.12metres above the global average• Land-based ice melt from glaciers, and from the Greenland and Antarctic
icecaps, may add up to 0.20metres. There is a great deal of uncertainty about the contribution from ice melt, with many scientists now saying it will be greater than currently predicted
• Storms will probably become more frequent and more intense, with stronger winds and heavier rainfall
• Ocean storm waves may become larger • The level of Lake Macquarie will rise by about the same amount, and at about
the same rate as the level of the ocean• Flood levels around the lake will be higher due to the general rise in lake level
and the increased rainfall intensity• Ocean tides may come further into the lake causing an increase in tidal range• Longer periods of hot dry weather may increase the threat from bushfires and
heat stress

• For policy and planning Council is assuming a rise in sea and lake levels of 0.91metres by 2100
• New development and building around the lake will have to consider the effects of increased sea level rise and flooding
• Local research and modelling will provide more accurate information on how the coast, lake, and creeks will be affected by sea level rise and other climate change impacts
• Mapping using aerial lasers (LiDAR) gives Council and the community a more accurate picture of the “lie of the land”, allowing better prediction of which areas may be affected by sea level rise and flooding
• Programs are being developed with communities to reduce the risk from climate change threats such as storms, fires, floods, and high winds
How can you help? • Participate in the activities of the Dora Creek climate
change adaptation group through your neighbourhood coordinator and come to future public workshops and events. We are planning events for 2009 and further details will be provided in the New Year
• Help protect and rehabilitate natural barriers to sea level rise such as vegetated creek banks and wetlands
• Plan new landscaping, buildings, and renovations to be energy efficient, and adaptable to sea level rise
• Be part of the solution by reducing your environmental footprint. For more information get a copy of the Lake Macquarie Sustainable Living Guide from Council’s web site or by phoning 4921 0333

What Council is saying
• Community empowerment programs are being run at Dora Creek and Swansea to give local communities more understanding of, and control over, how they will adapt to climate change
• Nature needs to be preserved and protected as well as property
What the Dora Creek Climate Change Adaptation workshop is saying
Due to predicted sea
level rise areas up to about 1 metre AHD may be permanently under water by 2100. Areas between 1 metre AHD and 2.5 metres AHD face an increased risk of
flooding from Dora Creek and the Lake, and areas between 2.5 metres AHD and 3 metres AHD also face an increased risk of flooding from Dora Creek. Due to predicted changes in weather patterns, storms may become more frequent and more severe. Flood models will be re-calculated over the next few years to more accurately predict changes to flood extent resulting from climate change.
Your neighbourhood coordinator (see back page) has a more detailed map showing land elevations at Dora Creek.
• Flooding is already a problem in Dora Creek, and it will get worse
• Some areas may be permanently inundated within 50 years if the lake rises as predicted, with roads, railway, drains, sewers, homes, and waterfront land affected
• Emergency responses to floods, fire, heatwave, and storms need to be better planned and coordinated
• Council and others should consider protective works such as levees, flood channels and dams
This aerial map of the mouth of Dora Creek shows the areas between current sea level (about 0 metres AHD) and 3 metres AHD.
