"How Hamilton's Ghost Rivers Haunt City's New Development"

"'Water always wins in the end': Lost rivers slow development and capture the imagination".

"Louie Santaguida's company is building a 30-storey condo tower in downtown Hamilton. And for a few months, he thought he had plans for its substructure nailed.

He'd already sold 70 per cent of the units, which include two-bedroom penthouses for $684,000. Then came an unexpected delay — an old stream under the future home of The Connolly.

"We're sitting on a former river basin from 10,000 years ago," Santaguida said in the fall. "We're overcoming geotechnical challenges. We've been doing that for the last three months." "
