It’s a big job that is expected to take five years, and here’s the catch: The buildings that may be in most jeopardy of being razed, "lost Bricktown,” are scheduled to be the last to be surveyed. Preservation architect Catherine Montgomery and Planning Director Russell Claus say the scheduling is a judgment call that could be changed. But they also add no such changes are being contemplated, though they admit the properties south of Ford Center could indeed disappear over the next decade. Will "lost Bricktown” disappear without anyone noticing? The upcoming survey may not just catalog historic buildings; it may end up measuring just how important historic architecture is to today’s leadership.
