Colliery Dams Questions

Did Inundation Study
Cost Nanaimo Taxpayers Millions?

City staff  have made some choices regarding the issue of the Colliery Dams.  They were presented with a study in April , 2010 which confirmed that the dams were vulnerable and that it was reasonable to assume that people would die as a result of dam failure due to a seismic event. This was the same conclusion of the review of 2008.  

Staff had decided in 2009 that they did not consider it a wise use of taxpayer funds to upgrade or replace the dams.  They chose to ask for a flood inundation study as “they were unsure which people would die if the dams failed” (as stated in our meeting of Dec. 06, 2012). Staff did not discuss this issue with council and did not inform the community of the potential risks.   

They did another study.

There is no mandate from the provincial authority to demand that a flood study be done.  The City did not request a flood study for Westwood Lake which was upgraded in 2008.  The estimated costs of repairing the dams and spillways in 2010 was $3,000,000. 

Revised classification standards were introduced in Oct. 2011and therefore did not apply to work suggested for the Colliery Dams. Staff should have to account for any discrepancy between costs associated with repairing the dams at this time and what could have been achieved a few years ago.
