Oklahoma City is the 20th largest city in the US and already has an 844' tower to it's credit and is taller than anything in Denver, Indianapolis, Columbus, Fort Worth, San Jose, Jacksonville, San Diego, San Antonio and Phoenix which are all larger cities. The Devon Tower is also 54' higher than Boston's tallest building. Time will tell whether the 1907' height ever gets built in OKC but the odds are pretty high that something substantial will eventually be built on that parcel. As far as Portland goes, we're punching above our weight when compared to other cities of similar size across the country. With 15 buildings that currently exceed 125' in the downtown area and a few more proposed, I think we're doing quite well for a city of only 70,000.
