The City of Markham is continuing field investigations to support storm sewer design in the Phase One and Phase Two improvement areas in West Thornhill. Phase One investigations will occur on Canadiana Drive and Phase Two investigations will occur within the area shown on the map below.

Field investigations include:

  • topographic surveys,
  • subsurface utility locates and marking, and
  • drilling of boreholes to confirm soil conditions in future construction areas.

These field investigations will begin in November 2013 and continue through early December 2013.

Construction of storm sewer upgrades and associated watermain replacement is expected to begin in the Phase 2 area in 2016.
