Well, hello to all! Let me jump right in and say that downtown doesn't have a height limit. The courthouse is built half on solid bedrock and the other half has pillars that are sunk at least 100 feet down. I did some research on the caves of downtown recently. I was told that the north side of the court house where there is bedrock could support the Empire State buulding while the south side has the pillars that sunk into the ground. I did email Triad ( the builders of the Summit and Ovation condos ) and express my thoughts on the 111 foot tall wall they are waiting to build. As for Research Park I don't see any buildings over 150' anytime soon. So, Adtran might hold the title for tallest out there for some time at 122 feet.
