HOUSTON — The Houston Astrodome has been in limbo, waiting for its chance at a second life since being shuttered more than 15 years ago.

It was a technological marvel when it opened in 1965. But its heyday has long passed and it hasn’t been home to a sports team since the Astros left in 1999 and it was closed to all events a decade later.

Over the years, ideas for its redevelopment and rebirth have been plentiful, everything from turning it into an indoor water park to flooding its sunken floor in order to reenact naval battle scenes. But none of these plans garnered enough public support or financing.

The latest proposal to refurbish the Astrodome was unveiled on Wednesday by a nonprofit focused on saving the beloved domed stadium. The group, the Astrodome Conservancy, proposes redeveloping the inside of the structure to create new areas for restaurants, retail, office and cultural spaces. But like the others before it, this plan could face a similar fate, with a $1 billion price tag and an initial lack of support from local entities that would need to give their OK for the project to go forward.

Beth Wiedower Jackson, the conservancy’s executive director, said that unlike previous proposals, her organization believes theirs is backed by data and would be economically viable in part because there would be enough private investment to support it.

“This is a big, big, bold vision. And those previous plans, even admitted by Harris County officials, were a first step towards a future Astrodome. And this is the full swing of the bat. And this gives people something to be excited about,” Jackson
