Groundskeeper confident Toronto FC, Argos can share BMO Field
"A new turf field — the third to grace BMO Field since artificial turf was removed in 2010 — is set to be installed this week, weather permitting. It has a much thicker base and should settle in much quicker and tighter.
It comes in rolls 60 feet by four feet (18 by 1.2 metres) and is laid on 12 inches (30 centimetres) of sand, which covers the heating and aeration system underneath."
"The grass will be kept a little higher for CFL games than MLS contests, if timing permits. That grass cut will help remove vestiges of the paint and Heggie says football players like a little more cushion in the grass.
Heggie also has some cosmetic cheats up his sleeve, like a green pigment and green sand that groundskeepers commonly use to touch up the colour as needed.
As part of the ongoing renovations to the stadium, two positions for the football goalposts have been installed. While just a yard or so apart, it means the football lines won't be laid down the same place every game."
