Dallas' skyline has a lot more room to grow if researchers have it right.

When it comes to development sites, downtown Dallas has the greatest development potential, according to a new study.

Big D already has one of the busiest downtowns with new apartments and retail developments, office buildings opening and a program to build four new downtown parks. But there's even more property available to ramp up construction in downtown Dallas, according to a new report by researchers at Yardi Systems Inc.

Downtown Dallas still has more than 86 acres available to build more stuff — the most of more than two dozen U.S. cities Yardi examined.

Las Vegas ranks second for downtown development potential followed by Austin and San Antonio.

"In the South, Texas is king — 208 acres of undeveloped land are scattered across the central business districts of Dallas, Austin, San Antonio and Houston," the report concludes. "The least dense CBD in Texas, as well as on our 25-city list, is Dallas, with vacant lots in the urban core adding up to 86 acres.

"Even with construction pushing inventory numbers up, downtown Dallas' development potential is yet to reach full blast and its denizens certainly think there's room for more, especially when it comes to housing, homeless shelters, parks and medical facilities."

Of the city residents polled, 77 percent picked more housing and parks as their most desired additions to downtowns.
