Well it looks like I have to issue a retraction. LA Central sure looks like it's headed to a groundbreaking very soon. They have temporary lighting on the property and they are building a construction fence out to the sidewalk on Figueroa and out to the street on 12th. That jibes with the renderings. Take a look...
Two pics from 12th street
Now two from Figueroa
This one is blurry, but the sign says "Morley Construction Company" and they've locked some small earth moving equipment behind the fence that looks like it could be used for the asphalt excavation. Nothing as big as a front end loader. More like some bobcat type stuff.
