How the Green Roof will sprout
As well as performing regular, state-of-good repair on the City Hall roof membrane, as part of the Nathan Philips Square Revitalization Project the City has installed an extensive green roof with 3,348 square metres (36,000 square feet) of vegetation).
The podium roof has been planted with a pre-vegetated, modular green roof system.
Modular systems are essentially trays of vegetation in a growing medium that are grown off-site and seamlessly installed on rooftops.
A diversity of plant species, grown regionally, has been selected for the City Hall podium roof for their seasonal colour and ability to withstand difficult rooftop conditions.
