The disused-but-beloved Houston Astrodome may have finally found its savior.

In early October, the commissioners of Harris County approved a $105 million proposal to reconfigure the aging Astrodome for events and concerts. Plans call for the floor of the vacant stadium to be raised so approximately 1,400 parking spaces can be built underneath.

Designed by two firms—Hermon Lloyd & W. B. Morgan, and Wilson, Morris, Crain & Anderson—in the mid-1960s, the 18-story Astrodome was added to the National Register of Historic Places in 2014. When it opened, it was the U.S.’s first enclosed and air-conditioned multipurpose stadium and boasted the largest clear span dome ever built. Before it shuttered in 2000, the Astrodome served as home field for the Houston Astros, the Houston Oilers, and the University of Houston Cougars. It reopened briefly in 2005 to accommodate New Orleans residents displaced by Hurricane Katrina.

Legacy aside, the Astrodome’s age and size present distinct financial challenges to adaptive reuse. Maintenance costs run to $170,000 annually, but tearing down the structure would cost $30 million. The just-approved proposal is all taxpayer funded:property taxes, hotel tax, and parking revenue will each contribute to a third of the cost, while 10 percent of the funds will go toward finding an architect and engineer to design the renovation. Once (if) the plan is complete, revenue from parking will be plowed back into the venue to make the project financially viable.

If the architect and engineer’s design ends up costing more than $105 million, however, the county will not cover the shortfall—local government will employ other, to-be-determined financing methods. Taxpayers defeated a measure to resurrect the stadium in 2013 over cost concerns, so it’s too soon to tell if this latest plan will bring the Astrodome back.
