There's a good backstory on the portion of the lot that's blocked. It originally belonged to H-E-B and when they relocated to the other side of the street in 2016 the sale of the property to the new owners did not include that parcel of land. When it was announced that Sprouts was coming, HEB decided to cordon off that portion of the parking lot that they still owned permanently to avoid any insurance risk for people parking in it.. quite frankly, it was a petty, stupid reaction intended to hurt the competition that Sprouts might bring to them.
