only trouble with this idea is that it takes, about 20-30 years for the young trees to even begin to resemble the 90 YO trees removed. I like the idea of planting more, but these aren't Pine trees that grow quickly. So you can't really replace the esxisting trees by planting new ones.
Simple solution though, if you have to cut down three live oaks, plant 12 more along the street in their place. Or however many necessary depending on the proper spacing for their root systems.
You people complain about traffic but when new roads are built you complain too?
Didn't some guy do a study that says Baton Rouge is the most green city (tree-wise) in the US?
