I think the garden project is a separate thing. It might be related, but isn't being done by Ambient, it's a local company. They took the trees out from around the site, and are planting new ones. The new ones have root barriers going way down into the ground, hence the big piles of dirt. I suppose it's either coincidence or they are making sure that the roots of the parking lot trees don't interfere down the road. Anway, Ambient wasn't there today.
