ALEXANDRA PARK REVITALIZATION-Urban Design Guidelines
As a major public realm element, the
streetscapes play a significant role in
defining the character of the Alexandra
Park community.
Streetscapes across the Site will be enhanced with pedestrianscale lighting, street trees, landscaping, decorative paving and
co-ordinated street furniture where possible. Particular attention
should be paid to the design of streetscapes and their elements
adjacent to park spaces, such as the pedestrian crossings at
Grange Court (Street “A”) and Carr Street (Street “B”).

•Sidewalksareafundamentalfeatureofthepublicrealm
and will be a minimum of 2.0 m in width, free and clear of
any obstruction to pedestrian movement;
•Sidewalksand/orboulevardsadjacenttoopenspace
areas or special crossing points may be given a
distinctive paving treatment, the design of which should
be complementary to the overall streetscape design.

Lighting
Lighting is not only a basic security requirement, but also
contributes to the character of spaces, and should support
vehicular and pedestrian activity levels.
•For personal safety reasons, all public spaces across the

Wayfinding
Entrances to the Alexandra Park community should be

landscaping and public art. Wayfinding, in the form of maps and
signage, should also be included at key entrances, as well as
within the central park system.

The proposed development form
creates good opportunities for the
implementation of sustainable practices
such as bioretention, green roofs,
porous pavement and rainwater re-use.
The selection of sustainable practices should be done with
consideration of technical criteria, value, aesthetics and public
acceptance, ideally at a master servicing level.
Landscaping
Landscaping of open spaces will minimize impact on the natural
environment by:
•Retainingexistingtrees,wherepossibleandbasedon
the Arborist Report (D. A. White, February 2012);
•Replantingnewtreestocompensatefortreesthatmust
be removed (D. A. White, February 2012);
•Usingnativetreeandplantspeciesinlandscapedesign
and incorporating drought tolerant species for shrub and
perennial areas;
•Usingrecycledorrenewableresourcematerials;
•Plantinglowmaintenancelandscapesinprivateyards.

Photovoltaic (electric) and solar thermal (water heating)
technologies may be integrated into the built form in Alexandra
Park, with consideration given to:

S
The proposed sustainable practices should complement other
traditional stormwater management components in keeping with
the objectives of the Wet Weather Flow Management Plan (City
of Toronto), and in consideration of the Low Impact Development
Stormwater Management Guide (CVC, TRCA).
Proposed rooftop systems and infiltration trenches are essential
to providing stormwater retention and addressing the water
balance requirements from the City of Toronto.

stormwater management areas (Functional Servicing
Plan, URS, 2012)
Utilizing planting beds and roof gardens to
accommodate infiltration of stormwater
All market apartment blocks will handle stormwater within each
block. Several locations for centralized stormwater management
are proposed for TCH blocks, which are located in Blocks 2, 19,
21 and 22. Each of these blocks will be a minimum of 6.0 m
in width to accommodate sufficient setback from underground
pipes and provide sufficient infiltration area. All stormwater will
be treated before being released off-site.

Green roofs will be installed on commercial, residential and
institutional buildings, in accordance with the City of Toronto
Green Roof By-law, to regulate building energy usage and
to assist with storm water absorption and filtration. Figure 27
provides approximate dimensions for green roof location and
size according to the By-law. The percent of available roof
coverage assumes 25% will be allocated to private terraces
or outdoor residential amenity areas. Figures shown are
approximate and based on building envelopes as depicted in
the Master Plan. Green roof calculations should be revised for
each building as they undergo detailed design.

PHAsINg sTRATEgY
Alexandra Park is a large and complex
project that will be developed over a
number of years. The phasing plan
reflects a socially and economically
sustainable strategy, premised
on the Guiding Principle of ‘Zero
Displacement’.
In order to ensure Zero Displacement, the implementation of
the master plan will require approximately 10 to 15 years to
complete, phased in nine construction stages. Construction
on the Site is anticipated to be relatively continuous with the
creation of public parks and streets in step with the construction
of adjacent new buildings and the refurbishment of existing
buildings to be retained.
The phased development also considers parking requirements
of existing TCH/Atkinson Co-Operative tenants and is organized
around maintaining sufficient parking to meet existing Site
parking demands during the phased construction process.
The master plan site layout and the distribution of uses
have been strategically organized in order to achieve Zero
Displacement, minimize disruption and ensure the financial
feasibility of the project. The pace of implementation is largely
determined by the on-site vacancy rate and may be accelerated
or slowed depending on how many people choose to move out
of the community in a given year.
The phasing plan is based on the assumption of an initial 5 vacant units which would be held in order
to begin the demolition and phasing program. A detailed phasing program, with the location and
number of units demolished and constructed, is provided in Figures 32 and 33.
