BC Hydro is preparing to move bulldozers into Jordan River before it wipes the Vancouver Island town's historic waterfront off the map.

After a six-year study found its dam risked catastrophic failure in the event of a massive earthquake, BC Hydro bought up all houses and buildings but one on the waterfront, slowly dismantling the tiny town.

Demolition of the buildings will begin in late March or early April, according to BC Hydro.

Once the foundations are removed, the land will be remediated with grass.

Along with buying homes, BC Hydro also purchased a 15-hectare swatch of flood zone near the townsite.
