Highway 1 — Capilano Road to Westview Drive Shoulder Widening

Planting (Environmental)

During the Open House August 22, 2011 there were inquiries whether residents could plant English Ivy on the sound walls, unfortunately English Ivy is considered an invasive plant. 

The Ministry would like to suggest planting other species which are either native or non-invasive ornamentals.

  • Maintain or re-establish adjacent pedestrian path to 2m width
  • Pathway to be extended 213m west and tie-in to the Pemberton pedestrian o/p. 
  • Entire length of pathway to have separation from traffic (880m) by concrete barrier.
  • Install 900m absorptive sound wall from the Capilano on-ramp to 70m east of MacKay Ave., 3-4 meters high.
  • Construct 460m concrete block retaining wall east of MacKay Ave to 190m west of the Edgemont Boulevard o/p.
