Three new reports on the state of Nanaimo’s Colliery Dams have been released by the City and made available online. Toby Seward, Nanaimo’s Manager of Social and Protective Services, says they expand on the initial geo-technical report by the engineering firm Golder Associates, released earlier this month.
Those two proposed options include significantly expanding the size of the spillway or reinforcing the top of the dam. He says those aren’t considered 100 per cent fixes, but they’re based on the risk assessment of the dams.
Seward adds that since the dams are in better condition than originally thought, some of the warning signs installed in the neighbourhood below will be removed.
Golder Associates will be making a presentation to Nanaimo Council on August 11 about the remediation options. A public meeting will be hosted in late August or early September to inform the public about what’s happening.
Seward met with the local media at the dams on Wednesday to provide an update on the remediation process.
