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 the following formula:
40% of the site area ÷ 66 m2 x 30 m3 = total soil volume required
Ensure that each separate tree planting area has a minimum space of 30m3 soil.1,2
Plant large growing shade trees along street frontages that are spaced appropriately having regard to site conditions, and that have access to a minimum of 30m3 of soil per tree.3,4,5
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

Where a setback from the top-of-bank is required within the Natural Heritage System or the Ravine Protected Area prepare and implement a stewardship plan for the area.3,4,5,6
Plant the landscaped site area using a minimum of 50% native plants (including trees, shrubs and herbaceous plants).1,2,3

Use a combination of the following strategies to treat a minimum of 85% of all exterior glazing within the greater of first 16 m of the building above grade or the height of the mature tree canopy (including clear glass corners, parallel glass and glazing surrounding interior courtyards and other glass surfaces):1
Fly-through conditions: Treat glazing at all heights resulting in a fly-through condition with visual markers at a spacing of no greater than 50 mm x 50 mm. Fly through conditions that require treatment include:5
Treat the first 4 m of glazing above the feature and a buffer width of at least 2.5 m on either side of the feature using strategies from EC 4.1.
Ensure ground level ventilation grates have a porosity of less than 20 mm X 20 mm (or 40 mm x 10 mm).

All exterior fixtures must be Dark Sky compliant. 1,2
Any rooftop and facade architectural illumination must be directed downward and turned off between the hours of 11 p.m. and 6 a.m.3
Non-residential: Install an automatic device that reduces the outward spillage of internal light by:
a) Reducing the input power to lighting fixtures by at least 50% between the hours of 11 p.m. and 6 a.m. year-round;4 OR
b) Shielding all openings in the envelope with a direct line of sight to any non-emergency light fixtures between the hours of 11 p.m. and 6 a.m. year-round.5
