Yep. They closed off the parking lot and replaced the fences a few months back.From the light rail train it appears they've started working at the Van Leer site.
There's some heavy equipment on the "South" site (South of Hoboken Ave).
The other side also has new gravel and a portable toilet, along with some other trailers
I'm not sure if they plan to do them both at once, or one at a time.
