This plot is only for sale now, nothing that I know of is planned. However, I think it is notable due to its size, over 14 acres. Though not highlighted, the Rockwood Go-Karts and Mini golf are also for sale by the same realtor.
Great location with very close proximity to Downtown, W7th, Stockyards, & Panther Island, direct access to the Trinity & Rockwood park. It's marketed as "Redevelopment Opportunity with Hotel, Restaurant or Retail Pad-Site Potential on the Edge of the Trinity River Vision Project."
Nearly the entire site sits in a floodzone, however. Not sure how the TRV might affect that.
