Hence my confusion.  You also wrote "Recently, OPA said, "As for street parking, this is allowed per Maryland Transportation Code that allows vehicles to be parked parallel to the right hand curb or edge of roadway – we confirmed with the Police that 2 wheels need to touch the easement area."

Since the easement area is outside the road edge, OPA's position is that as long as two wheels are in the grassy easement by 12 inches or more the vehicle is legally parked.
