AtD translation: back of

[Mike Jing]

P526.28-30   The Grand Hôtel de la Nouvelle Digue was tucked well back of
the Boulevard van Iseghem, far from the seawall it was named for, its
appeal being chiefly to the cautious of purse . . .

Also:

P468.5-6   “Mayva? heck she’s just a couple blocks from here, runs that
ice-cream parlor, Cone Amor, over back of Myers.”

P850.16   They sat outside a café in back of the Square Garibaldi.

I know "back of" means "back from, behind". How exactly does it apply to a
street or a square?
