The group that completed the purchase of a 15-acre agglomeration of tracts at the southwest corner of I-10 and Studemont this week says it’s planning a mixed-use development for the site, including an apartment complex. Most of the land was owned by Grocers Supply, which has operated a 232,352-sq.-ft. produce warehouse and big-rig parking lot there for 42 years. The facility at 3000 Hicks St. is yet another chunk in the First Sixth Ward-area once-industrial swath south of the Heights that’s been turning to big-box-flavored retail bit by bit over the last decade, and now stretches from Target on the east near Sawyer to Walmart just west of Yale St. Here’s an aerial view of that district from 1990, when it was still entirely industrial (you can see the western edges of Downtown in the background):
