Environmental and Archaeological Management:

Ongoing inspections have taken place since the start of the construction by the municipalities' Environmental Monitor (AESC) and the Contractor's Environmental Monitor (Aquaparian) and no major issues have been identified;
The majority of work within the waterway is now complete (just the removal of the work bridge and fingers are left); therefore environmental attendance will be reduced to bi-monthly visits or as requested by the project team;
Request made for extension of DFO Valid Authorization Period from February 15th, 2013 to June 30th, 2014;
Staff received complimentary letter from Gorge Waterway Action Society for the environmental monitoring that has been/is being done during construction;
Staff working with Golder and First Nations to organize the final funeral service, burning ceremony and feast which will be taking place on December 11th, 2013 at Esquimalt Nation.

Traffic Management:

No complaints received since the November COW report;
Admirals Road open to local traffic; temporary stop signs in place at the intersection of Admirals Road and Gorge Road until upgraded signal is operational;
Gorge Road from Admirals Road to Tillicum Road continues to be closed for Saanich sewer system upgrades;
Pedestrian walkway re-surfaced, safety improvements made and repairs to lighting carried out;
Saanich RCMP spot monitoring and issuing tickets to cyclists not dismounting while using pedestrian walkway.

Communications:

Ongoing updates to website;
Staff working on strategy to mitigate the impact of the further delay in the bridge opening on businesses – focus will be on the bridge opening; staff has been in contact with certain businesses regarding delayed opening;
Staff continues to receive very few enquiries and complaints to date.
