A new seven-storey condominium is set for construction on River Road despite strong opposition from local residents.

Approval for the controversial plan was given by council on Monday after both sides presented their case to city councillors.

"Residents have serious concerns about the impact construction will have on their homes," said Tom Richardson, a lawyer hired by residents to stop construction or change the proposed plan.

The high-end, 119-unit, residential development, ranging in height from four to seven storeys, was originally presented as a 29-storey tourist commercial building in 2006, but later amended when residents first voiced concern over the size and impact the complex would place on their community.

Residents said traffic would significantly increase and noise would cause disturbance. Developers came back with a different, scaled-back version of the plan, downsizing the building significantly and changing to residential apartments.

"We believe this proposal is the best option for the developer, the subject area and the subject lands," said Italia Gilberti, a lawyer representing the developer.

But despite the changes, residents still believe this building will be highly intrusive. "It's too large and too dense," said John Prentice, a resident of neighbouring John Street.

Five councillors voted to keep the plan as is, with Coun. Bart Maves and Coun. Janice Wing opposed. Coun. Wayne Thomson declared a conflict of interest and sat out on the vote.

Architect Dan Cowling of SMV Architects said the building will feature lush greenery, using plants native to Niagara and will also showcase a large water fixture, resembling a waterfall, on the front exterior.

Developers hope to start construction immediately.
