I sent e-mail to Town Center, so they're aware of it. I heard the large tree fall and saw its top going down before I knew what was happening. This was while I was walking down Vantage Point Road in Columbia Town Center just before 4pm. It's in the strip of woods between the park on Vantage Point and Oakland Manor and the African American Museum. The tree is leaning against some smaller trees and still settling.
I'm guessing that the tree cracked near its base during the storm but didn't fall right away. This is a nice little safety hazard and further tree loss to worry about a week after Irene has passed by.
