New meaning to the term green line

After what seems like years of construction. Commonwealth Avenue near BU is finally rounding into shape -- albeit with a much narrower roadway.

I have no qualms whatsoever about the efforts to snazz up the sidewalks on both sides of the street. But I am curious about the decision to install sod -- sometimes in infinitesimally small strips -- along the trolley right-of-way. Talk about a green line!

And to install sprinklers to keep this tiny patch of grass green.

The big question -- who is paying for it? If it's BU -- fine and thanks for trying to beautify a strip that give a new meaning to the term ugly.

If it's the MBTA -- can we look forwards to a fare hike to pay for the water that gets sprayed in the tracks?
