Over the weekend, variance signs were posted at the dead-ends of Sul Ross and Branard St. near the Menil Collection and in front of the bank of antique shops facing Dunlavy. The notices are the clearest indication yet that some big new development is being planned to replace the Fiesta Food Mart at the corner of Dunlavy and West Alabama in Lancaster Place. Last month, Swamplot posted a reader’s report that the property had been sold and that a 6-or-7-story “West Ave-style” mixed-use project was planned for the 3.68-acre site.
