COUNTY APPROVES FIRST $10.5 MILLION FOR ASTRODOME BASEMENT PARKING GARAGE PLAN The Harris County commissioner’s court voted this morning to approve the design phase of that plan to fill in the Astrodome’s below-grade levels with a 2-story parking garage. Mihir Zavari writes that today’s vote okayed the first tenth of the estimated $105 million cost, which the commissioners say will be split between hotel taxes, parking revenue, and the county’s general fund;Â Zavari notes that “the general fund component, around $30 million, is roughly equivalent to the amount the county estimates it would cost to demolish the Dome.” [Houston Chronicle; previously on Swamplot] Image of Astrodome parking garage conversion plans:Â Harris County Engineering Department
