I thought they bulldozed it. I heard that the Katrina fugitives trashed it beyond recognition.
nope, it now has a texas historical commission designation so even if they wanted to tear it down they would have to get approval by the thc.
last plan by the harris county commissioners was to basically fill in the field area and i believe lower seats to create a parking garage generating revenue for the county and then using the concourses and "roof" of the parking garage for event space.
total cost was estimated at just over $100M and the commissioners all agreed on the plan.
one small issue, the approved plan did not deal with the issue of the repair/replacing the air conditioning system in the dome. emmett and the commissioners approved the plan knowing they had not addressed what they were going to do about the ac system, basically kicking the proverbial can down the road.
harvey hit and now the group is focused on the $2.5B bound project to address flooding issues so once again the astrodome goes on the back burner costing the county money and going further into disrepair.
