"Rejuvenation" and the theft of Public Spaces

I recently inquired as to the legality of the permanent fencing off of Concert Square by the Bar owners and was informed by the City & North Neighbourhood Services, Liverpool City Council that the Square was the property of Baa Bar group however when I further asked how come their fencing encloses public seating and the pavement on one side the square- I received no response- does anyone know where a member of the public can get access to detailed maps showing boundaries because the Baa Bar group are undoubtedly stealling public property- which they then use to ply cheap drink to drunks and make the so called "Street Cafe" atmosphere in truth an outdoor Gin Palace- complete with violent atmosphere, puke, piss and the loud banal monoculture which passes as rejuvenation.
