Create tree planting areas within the site and in the adjacent public boulevard that meet the soil volume and other requirements necessary to provide tree canopy. Determine the total amount of soil required by following the following formula:
40 per cent of the site area ÷ 66 m² x 30 m³ = total soil volume required
Ensure that each separate tree planting area has a minimum of 30 m³ soil.1,2
Plant large growing shade trees along street frontages that are spaced appropriately having regard to site conditions and have access to a minimum of 30 m³ of soil per tree. 3,4,5
Parking Lots: If surface parking is permitted and provided, plant large growing shade trees throughout the parking lot interior at a minimum ratio of one tree planted for every five parking spaces supplied.6
Provide a watering program for trees for at least the first 2 years after planting.7
If surface parking is provided, plant large growing shade trees at a minimum ratio of one tree planted for every three parking spaces supplied.6
Provide 25 per cent more than the total soil volume required as per EC 1.1. Soil shall be deployed on-site or on adjacent properties as approved by the City of Toronto.1,2,3,4,5

Provide a minimum of 50 per cent of Available Roof Space as biodiverse green roof.7,8
Buildings abutting ravines or natural areas:
Use a combination of the following strategies to treat a minimum of 85 per cent of all exterior glazing within the greater of first 12 m of the building above grade or the height of the mature tree canopy: 1
Balcony railings: Treat all glass balcony railings within the first 12 m of the building above grade.3,4,5,6
Fly-through conditions: Treat glazing at all heights resulting in fly-through conditions with visual markers at a spacing of no greater than 100 mm x 100 mm. Fly through conditions that require treatment include: 7
Ensure ground level ventilation grates have a porosity of less than 20 mm X 20 mm (or 40 mm x 10 mm).
Use a combination of the following strategies to treat a minimum of 95 per cent of all exterior glazing within the greater of the first 12 m of the building above grade or the height of the mature tree canopy (including all balcony railings, clear glass corners, parallel glass and glazing surrounding interior courtyards and other glass surfaces):
