I found the reason for the delay. Austin are asking them to do a detailed survey of the trees to show which ones need protecting due to their size
I love it !.
This is how one should be zealous and protect their environment. Trees take a long time to grow, at least in the Dallas area it takes upto 20 years for a tree to fully grow with a decent canopy. To somehow destroy it due to carelessness of a contractor, or greediness of an establishment will be real bad.
