A number of recent developments have transformed the 170-acre Deep Ellum district from a nightlife-focused region that included fewer than 300 residents in 2005 to a vibrant, mixed-use neighborhood with strong economic growth and more than 2,000 residents living there today, making most of the area lofts and apartments fully occupied. The district is experiencing a dramatic turnaround with residential housing, new dining options and retail establishments opening regularly, and a significant $10 million Elm Street renovation under way.
