Hi, Asher,
Thanks for that lovely shot.
I don't know what that strip of lawn where the trees are is called in Beverly Hills, but where I grew up in the Cleveland area we called that the "tree lawn".
There were always complicated arguments about lot lines and whose responsibility it was to maintain the "tree lawn" in various ways.
In all the places we have lived lately there have been no such. Some places didn't even have sidewalks, but we do here in Alamogordo (this neighborhood was developed in perhaps 1978.)
Best regards,
Doug
