HOUSTON (AP) — Initial funding has been approved for a $105 million redevelopment of the Houston Astrodome that would include raising the two bottom floors to accommodate about 1,400 parking spaces. Harris County commissioners voted Tuesday to spend $10.5 million on the project's initial design. Plans call for the bottom floors of the county-owned Astrodome to be raised for parking so that it can be used for festivals, conferences and commercial uses across more than 550,000 square feet of air-conditioned space. Parking revenue, hotel occupancy taxes and county general funds are expected to cover the cost of the redevelopment.
