Downsview Water Service Improvement Study Maps

1. Municipal Class EA
Process
4
The Project is following a “Schedule B” Municipal Class EA
Planning and Design process which requires following the
process outlined below:
Phase 1: Problem or
Opportunity
Phase 2: Alternative
Solutions
Implementation
Identify problem or opportunity
Identify alternative solutions to
problem or opportunity Complete drawings and documents
Inventory natural, social and
economic environment
Proceed to construction and
operation
Identify impacts of alternative
solutions on the environment, and
mitigation measures
Evaluate alternative solutions and
identify recommended solutions
Consult the public and agencies
regarding the recommended
solution
Select preferred solution
Monitor for environmental
provisions and commitments
We are
here!
Consult the public, agencies and
other stakeholders regarding
problem or opportunity and high
level alternative solutions

2. Study Area – Growth and
Development
6
The Study Area is generally
urbanized and is expected to
see major growth in the
future. This study will address
water demand up to 2041.
There are three secondary
plans within the Study Area
that identify how the area will
grow:
• Downsview Area
Secondary Plan – covers
the south central part of the
Study Area
• York University Secondary
Plan – covers the area
south of Steeles Avenue and
west of Keele Street, north
of the hydro corridor and
east of Black Creek
• Sheppard West-Dublin
Secondary Plan – extends
from William R. Allen Road
along Sheppard Avenue
West to Canyon Avenue

3. Study Area – Water
Pressure
7
The minimum water pressure
mandated by the Provincial
Government is 40 psi. The
City’s water pressure varies
from a minimum of 40 psi to a
maximum of 115 psi in each
Pressure District (PD).
Existing businesses and
residences within PD5 (pink
boundary line) are
experiencing low water
pressure.
Tell us what
you think!
Do you
experience low
water pressure?
If so, where?

4. Study Area – Existing
Environment
8
Natural environment
features include:
• Watercourses (including
Black Creek and the West
Don River) and the
surrounding vegetation
• Vegetation within
Downsview Park and street
trees
Cultural heritage features
include:
• Downsview Park
• Built resources associated
with Bombardier Aerospace
and CFB Downsview
Archaeological resource
potential is limited to areas
that have not been disturbed
or in close proximity to
watercourses.
Other features and potential
impacts may be identified
during further desktop and
field investigations.

5. Study Area – Other Studies
and Projects
9
A number of transportation
projects are currently in the
planning, design or
construction stages, including:
• Downsview Area Major
Roads Class EA
• Metrolinx Finch West Light
Rail Transit (LRT) Project
• Metrolinx Barrie Rail
Corridor Expansion and
Electrification Project
• Toronto-York Spadina
Subway Extension
The City has also recently
initiated the Keele Finch Plus
Study to develop a planning
framework to encourage
growth and investment in the
area. This planned growth
and investment is a result of
the development of the
Toronto-York Spadina Subway
Extension and the planned
Finch West LRT.

6. Alternatives 2A, 2B and 2C
Watermain Route Options
11
These alternatives were
identified based on:
1. Providing water from the Keele
Reservoir and Pumping
Station to the Study Area.
2. Looking at north-to-south
routes leaving the Keele
Reservoir and Pumping
Station and heading south to
the Downsview Area – West of
the Metrolinx Barrie Corridor
3. Consideration of existing and
future transportation and utility
corridors including arterial or
collector roads where
available or planned
4. Feasibility of easements and
available local roads that can
provide connectivity for a
continuous watermain route
between the Keele Reservoir
and Pumping Station to the
Downsview Area
Alternative 2A:
Keele West
Alternative 2B:
Chesswood-Alness-Steeles Central
Alternative 2C:
Dufferin East
For each option, a new and
approximately 600 mm diameter
watermain will also be required
from Keele Reservoir and Pumping
Station to Pond Road.

8. Alternatives 3A, 3B and 3C
Pumping Station &
Watermain Route Options
13
These alternatives were
identified based on:
1. Focus on central part of the
Study Area considering
proximity to large water
supply mains
2. Site size and shape
(approximately 600 m2)
3. Preference for vacant land,
publically owned land or
willing host
4. Avoidance of lands with
natural features or
significant investment
5. Use of existing or future
transportation and utility
corridors for watermains
Alternative 3A:
Pumping Station Site K – Bombardier Airstrip
Alternative 3B:
Pumping Station Site L – 35 Vanley Cres.
Alternative 3C:
Pumping Station Site M – 1026 Finch Ave. W.
