Detail - Tree Planting, Typ

Ok, so yeah, this is the city's Standard Plan No. 100a for planting a street tree--in case you have an eagle-eye for recycled detail drawings. Hey, it's public domain. I have made a few improvements, however. I've added instruction to keep mulch clear of the tree graft. Also, I visually tried to show "slack" in the ties, although, the tree still looks like it's in handcuffs...
