Edwards Gardens Parking Lot, Toronto Kylemore New Yorkton (Deacon Property),

Markham

Angus Glen Development


Stantec Consulting Group

Objectives:

– Establish compact medium density community

– Integrate infiltration galleries to moderate temperature

– Achieve enhanced water quality through creation of a “forested swamp”

Kylemore New Yorkton (Deacon Property), Markham

Inlet to Infiltration Basin

Infiltration Basin

Forested Swamp

Kylemore New Yorkton (Deacon Property), Markham

Considerations:

o Condominium model

allowed for flexibility to

integrate solutions

into streetscapes

o Compact built form

presented challenges

and conflicts with

utilities, fences, etc.

o More integrated

approach to construction would have been beneficial

o Draft plan approved prior to L.I.D. integration

o SWM techniques are amenities within the community
