Didn't the post office there do a lot of sorting that is now done in OKC?
Yes, it's only partially occupied. Another reason the Post Office should relocate and open this site up for redevelopment. Hopefully our new mayor will take this up - as horrible as he was Mayor Bartlett was actively working on a plan. From the TW article:
Under Mayor Dewey Bartlett, the city in 2011 began the process of trying to purchase the Page Belcher building, but the complicated transaction never gained traction. The plan included having the Tulsa Industrial Authority partner with a private, third-party entity to purchase the building - the estimate then was for $10 million - and lease it back to the federal government over 15 to 18 years. At the end of the lease, TIA would take take ownership of the building.
