2.2 Podium Height and Massing
a) The height of the podium, and the tower stepbacks above, should generally refl ect the established streetwall subject to the guidelines
create a varied streetscape. b) Where no established streetwall exists, the minimum height of the podium should be 10.5 metres. c) The maximum height of the podium should be 80% of the adjacent right-of-way width, up to a max of 20 metres. d) The fl
fl
accommodate internal servicing and loading, and active commercial uses (where permitted). e) Above the podium, stepbacks should be provided on all sides to clearly diff erentiate between the building podium and tower. f) Stepbacks should be a minimum of 3 metres to ensure usable outdoor amenity space (i.e. patios).
2.3 Shadows/Sky Views
a) As a rule-of-thumb, the height and massing
ensure a minimum of fi ve hours of sunlight on the opposite side of the street at the equinoxes (March 21 and September 21).

3.1 Tower Location
a) The placement of the tower shall have no adverse impacts on adjacent Residential Neighbourhood Areas, parks, open spaces, or natural areas. b) Where multiple towers exist on a site, they shall be arranged to provide a gradual and appropriate transition in height to adjacent uses. c) A minimum separation distance of 25 metres shall be provided between towers to maximize privacy and sky views, and to minimize the cumulative shadow impacts of multiple tall
within this separation distance. d) Where no towers currently exist, proposed towers shall be set back 12.5 metres from adjacent property lines to protect for a future 25 metre separation distance (split between each property). e) The tower should be stepped back at least 3 metres from the podium to diff erentiate between the building podium and tower, and to ensure usable outdoor amenity space (i.e. patios). f) For design fl exibility, a portion of the tower (i.e. up to 20%) may extend to the edge of the podium without a stepback provided it can be demonstrated that there are no adverse wind impacts.

3.3 Shadow/Sky Views
a) The design and placement of the tower shall be carefully considered to minimize the size of shadows on the opposite streetscape, and the time it takes for them to pass. b) The design and placement of the tower shall have minimal impacts on adjacent residential neighbourhoods, parks, open spaces, or natural areas. Adverse shadow impacts shall not hinder the viability or enjoyment of these areas.

c) The widest edge of the tower should generally be oriented in an east-west direction to minimize the impacts of shadows. d) It is recommended that a shadow study be provided with tall building applications to demonstrate the impacts at the equinoxes (March 21 and September 21).

Tower form reduces adverse visual impact
is narrower and faster moving. Lower tower height decreases shadow length, while higher podium frames Brant and James intersection in a more urban manner, without signifjcant shadow difference. 27 STOREY PROPOSED 23 STOREY
