Calgarians living, working and playing downtown can once again enjoy the green space above Fire Station 1 with the re-opening of the Rooftop Plaza.

At 450 1st St. S.E., the plaza is accessible via the Plus-15 bridge from the Telus office building to the Delta Calgary Downtown, through the second floor of the hotel, and from the stairwell next to Baker House.

Having green rooftops and plazas, said Coun. Druh Farrell, is an important part of a vibrant and environmentally friendly downtown.

"They're heat sinks, they cool down the neighbouring buildings, they provide some diversity for pollinators, for birds, and they provide an oasis for a really busy downtown," she said.

"Downtowns can be biodiversity deserts for pollinators so the more you have these spaces, the more you can have a healthy, pollinating community."
