Nothing whatever has been done about this! More sidewalk now blocked with these signs. Are you doing anything about this?

I doubt anything will be done for this. The city sidewalk is only the cement portion on the left side of your photo. All bricked areas are the private property of the brick market condo association so the merchants are within their right to place sandwich boards there.

signs are on private property
