District of North Vancouver staff is seeking council support on a grant application to replace an undersized culvert in Deep Cove.
The culvert conveys Gallant Creek below Gallant Avenue to Panorama Park where the creek discharges into Deep Cove via an open channel.
Staff will seek council’s approval to apply for a provincial grant at an upcoming meeting on January 11.
The project is a major component of the District’s Drainage Asset Management Plan and will increase the system resiliency to extreme flood events, staff says.
Gallant Creek is prone to debris floods which raise concerns related to blockages at road crossing culverts, staff notes.
During the 2014 flood, partial culvert blockages occurred at three culverts, including at Gallant Avenue.
It led to flooding that impacted 12 properties, including residences, businesses and the Deep Cove Cultural Centre.
Four years later, flooding occurred when the Gallant Avenue culvert inlet was again partially blocked resulting in overland flooding, impacting an adjacent apartment building and commercial properties on Gallant Avenue.
The culvert replacement project, staff says, is a critical component of the overall flood mitigation work plan for Gallant Creek that includes berms, a debris basin, channel improvements and culvert replacements.
The total capital construction budget for the project is $7.9 million, which will be completely funded by the provincial grant.
Construction is expected to start this summer and anticipated to be complete by December 31 this year.
