This is the ground floor pad for the retail low-rise on Park Lawn. It butts up against the Key West low-rise to the right of the pic. There was some talk a chain like Earl's or The Keg or some such would go in here.
The wall beside the road is temporary while Encore is under construction. When it's done, the internal roadway will continue across the concreted area just beyond the wall, and up to Key West.
That last shot shows cars lining up on the driveway that goes up to Park Lawn Road. It seems the timing may need to be adjusted. Encore is under construction just behind the cars.
