They're moving quite a bit of dirt on SW 44th across from Hobby Lobby on the east side of the railroad tracks. There's also a construction trailer. Any idea what they're getting ready to build?

Maybe this?

It's a 180,000 SF building for Hobby Lobby.

They call it their "IS Building" which probably means it's a data center.

that would make sense... my understanding is that even before covid, hl's online sales volume was rapidly increasing.

The drawing over emphasizes the size of the creek, but if this is a data center, putting it next to any sort of water is a bone-head move.

I believe the drawing is pointing out either an area around it that can't have any construction or its potential growth during heavy rains.
