Queen's Ditch Outfall and Culvert Rehabilitation- 19 Wing Comox

The Department of National Defence (DND) has proposed a project. The existing corrugated steel culvert located at the Project Site has reached the end of its service life. This existing culvert will be replaced with an upgraded precast concrete box culvert with an open bottom for placement of appropriately sized salmonid spawning gravel and other fish habitat features.

The new culvert will be extended to meet flush with the current retention wall (outfall) on the east side of Lazo Road, to eliminate debris build up with the current configuration. This work will require excavation and backfill activities for removal of the existing culvert, installation of the new culvert, installation of the new precast concrete headwall on west end of the culvert, and reconstruction of the new precast concrete block retention wall on the east end of the culvert crossing. The backfill will be approved structural fill materials. Single lane traffic will be maintained throughout the Project, and Lazo Road will be restored and repaved with asphalt once outfall and culvert installation are complete. All works will include environmental mitigation measures required by legislation, policies, and permits as applicable.

Latest update

August 18, 2023— Canadian Forces Morale and Welfare Services issued its Notice of Determination and determined that the project is not likely to cause significant adverse environmental effects.
