Sea level rise poses flood risk for Delta Researchers use 3D technology to illustrate need for flood strategy Sandor Gyarmati Delta Optimist

DELTA – Planning needs to be done now to address the future sea level rise in South Delta, say researchers who provided ominous visuals of what could unfold. Current estimates have the sea level rise for South Delta at about 1.2 metres by 2100. However, at a science symposium in Vancouver on the weekend, a pair of researchers made a more dire prediction, contending the original estimates might be too conservative. David Flanders of the University of B.C and Simon Fraser University professor of geology John Clague told a symposium for the annual convention of the American Association for the Advancement of Science that planning is needed for the possibility of a more rapid rise. Using computer visualizations of rising sea levels in a low-lying coastal municipality

Delta participated in a UBC project using visual modeling and computer techniques to come up with 3D images of what Boundary Bay might look by 2100 due to sea level rise. like Delta, they illustrated ways to adapt to climate change impacts such as flooding and storms surges. “To me, the visualizations are the only way that you can tell the complete story of climate change and its impacts in a lowlying coastal community,” said Flanders,

with the Collaborative for Advanced Landscape Planning (CALP), prior to the symposium. Delta participated in the federally funded project, which shows what the community would look like if nothing is done. According to CALP, there’s an urgent need

for governments at all levels in Canada to make decisions concerning adaptation and planning strategies. Noting planning is already well underway on how Delta can deal with a 1.2-metre rise in sea level by the end of the century, deputy engineering director Hugh Fraser said current estimates are based on information from government and scientists. Delta’s dike system is constructed to what’s described as a 200-year flood level, which means the risk of flooding is estimated to be 0.5 per cent in a given year. That means there’s is a 99.5 per cent chance that flooding from high water will not occur. What’s not clear is how the current dike system would hold up with rising sea levels due to climate change by 2100, but the computer images suggests there needs to be upgrades. Fraser, noting a number of works to dikes and pump stations have already been done, said upgrades would be gradually carried out as funding becomes available. He said the province is also undertaking a study to look at the costs of improving the coastal flood protection system.


AN INVITATION TO A PUBLIC OPEN HOUSE You are invited to a public Open House to provide input on the second phase of a feasibility study for the development of a Sports, Arts, Culture and Harmony Centre in Newton. The centre would provide facility space available to the entire community including multi-purpose rooms, culture and heritage interpretation display areas, gymnasiums, fitness rooms, a restaurant and day care. Staff and consultants will be on hand to receive community feedback. The first phase of the feasibility study researched a proposal to develop a community centre on lands at Princess Margaret Park. A public Open House was held in November 2011 to present this proposal to the community. Since that Open House, Council has directed staff to investigate other possible sites for the centre. Staff and consultants have researched two other possible sites at Unwin Park and on City owned lands in Newton Town Centre. Plans and information for the feasibility of the three locations will be on display at the Open House.

The Open House will be held on: Date: Tuesday February 28th, 2012 Time: 6:00 p.m. to 8:00 p.m. Place: Cedar Building -- Conference Room Kwantlen Polytechnic University 12666 72nd Avenue, Newton, Surrey

If you have any questions, please call 604-501-5050 or email


The City of Surrey invites you to visit the Open House to provide feedback to identify community needs and issues on the development of the centre.
