A rooftop meadow: Charlottetown contractor wants to see more green roofs

When Shaman Ferraro gazes across Charlottetownfrom the 11th-storey green space on the Holman Grand Hotel, he sees a lot of flat, greyroofs.

"You can see the stark difference of the green roof behind me compared to the flat roofs in the area off the Holman."

The hotel hasfour smallgreen spacesthat were put in when the building was constructed in 2011.Ferrarowas recently hired to rejuvenate them.

'Beautify the downtown'

But as the owner of Atlantic Green Contractors, Ferraro sees many possibilities.

"We only have four green roofs in Charlottetown," Ferraro said.

"In a city centre that is growing and looking to continue to grow, where tourism is a huge industry and hospitality is a huge industry, I see a lot of opportunity to beautify the downtown."

'Allowing the native species to establish'

One of the biggest benefits of a green roof is evident after heavy rainfalls, Ferraro said. Normally, buildings and parking lots are designed to carry storm water away as quickly as possible into the city's storm sewers.

But sometimesthe city's infrastructure can't handle the heavy rain, resulting in flooding and an overflow at thetreatment plant.

"One thing a green roof can do is absorb that rainfall and release it at a slower rate," Ferraro said.

"What this does is reduce the combined sewer overflow and the stress on the city infrastructure."

Ferrarosaid a green roof adds additional weight, something that needs to be factored in during design and construction.

"It's not that we can't do it. We'd just have to get an engineer to assess the building."

So if green roofs are such a good idea, why aren't there more here?

In 2009,the City of Toronto mandated thatnew buildings over six storeys must include agreenroof.

Charlottetown's green roof bylaw only applies to new buildings downtown.

New buildings need to dedicate 25 per cent of the available roof to green space whether a green roof or traditional landscaping. Or, 10 per cent of the entire lot size needs to be green space whichever is greater in size.

But rather than tougher bylaws, Ferrarowould likeCharlottetown to offer incentives to developerswho put in green roofs and charge a small fee for those who don't.

"A property owner who didn't want to put in a green roof could be forced to pay $50 or $75 or $100 a year, but it is money that would then help offset the cost of a green roof program," Ferraro said.

"Currently, all of our storm water management fees come out of taxpayer dollars."

'Reducing the effect of urbanization'

Ferraro also suggested more education is needed, for developers and the public.

"The issue we're trying to solve here is really just repairing the environment and reducing the effect of urbanization."

A spokesperson for the city of Charlottetown says while green roofs are a great idea, there are currently no plans to bring inincentives or education programs.
