This report called for a 'smaller' Steeles terminal than originally envisioned..............at 16 bus bays.
My instinct is that that remains overkill.
But its all I have to go on, in terms of the land area implications of a terminal at grade.
In respect of comparisons to other stations, York Mills is 2 different terminals as I recollect, and the surface environment despite being covered by buildings is atrocious.
Sheppard is not directly on Yonge; and is due to be built over, the hold-up there has been the City's desire for commercial space over top rather than residential.
Finch is 2 different terminals and occupies an obscene amount of land, but was built in behind existing retail on Yonge.
Not sure I see any of these as ideal role models.
