>85% GHG Reduction**Operational Only

Sidewalk Labs will invest in a series of innovations that drastically

reduce greenhouse gas (GHG) emissions below levels in

comparable projects, enable smarter management of resources,

and reduce the cost of future upgrade and maintenance.

Issues

● Lack of stormwater BMPs (especially Green Infrastructure)

● Spills and Point source pollution

● CSOs (Combined Sewer Overflow)

● Aging Infrastructure ● Lack of funding ● New development exceeds

old design criteria

● Increased storm frequency and intensity

● Increase in impermeable surfaces

● Infrastructure failures

● Change in infiltration rates due to soil quality or groundwater table

● Change in land use ● Parcel by Parcel

Our

Approach We will design with natureinstead of thinking we can entirely control it

8


Green stormwater infrastructure

provides a place for water to go during storms while acting as a natural filter

District-level SWM system

to exceed current Toronto Green Standard retention requirements for added resiliency

Soil volume >40% exceeding City of Toronto target and Green Streets Guidelines

Green roofs and blue roof

(for water retention/detention) under solar PV on terraces and podium rooftops become distributed resources

Permeable and heated pavers

for natural retention, filtration, and to eliminate salt runoff into the lake

Active stormwater management

and ecological systems could cut downstream energy costs by >50% and cut the water moving to municipal systems by 90%

Approach:

Active control providing the

ability to hold back additional water from the storm system

freeing up capacity for neighboring properties
