Action Plan for
Colliery Dam Concepts
City staff continues to carry
out Council’s direction from the December 17 regular Council
meeting to engage professional engineers to undertake
conceptual level cost estimates for rehabilitating or rebuilding the Colliery
Dams concurrent with engineering design and environmental study work to remove
the dams and re-naturalize the Chase River.
The current status of the
two-stage action plan announced December 24, 2012 is as
follows:
1. Klohn Crippen Berger
(KCB) was retained to undertake conceptual level cost estimates for the Colliery
Dams. KCB has extensive experience with the assessment, design and construction
of dams, are familiar with the recent studies and assessments of the Colliery
Dams, and have excellent knowledge of British Columbia’s Dam Safety Regulations
and Standards. KCB was also retained to carry out the design work necessary to
fulfill the proposal to remove the Colliery Dams.
2. The City has issued a
Request for Proposal for the purpose of hiring an engineering consultant to
complete a peer review of KCB’s cost estimating work. The peer review will
involve an assessment of the concepts being considered for rehabilitation and
rebuilding. Based on that initial assessment, KCB will then develop the
conceptual level cost estimates. Those cost estimates will also be subject to
the peer review process.
During the months of December 2012
and January 2013, City officials, along with members of the Province’s Dam
Safety Branch, met with a delegation of community members seeking an alternative
solution to removing the Colliery Dams. Through the two-stage action plan
outlined above, the community delegation will be invited to provide input to the
peer review engineer, who will then work with KCB on the alternatives to be
developed. The City also remains available to meet with the community
delegation should new information be identified.
The City anticipates both stages
of the action plan will be completed by mid-April, with the opportunity to share
information with the community delegation occurring in late February or early
March.
