I recently visited Cira Green, a park in Philadelphia that's located on top of a parking garage, about 100' off the ground. The park features numerous garden beds and native trees. There are a number of challenges that come with planting trees on elevated surfaces including soil volume and mixture, wind, and a dynamic load. However, when done correctly, these green roofs can offer numerous benefits including wildlife food and habitat, storm water control, and providing the public with a nice public place to visit.

Gorgeous! My climate is very dry which might make this kind of project difficult. Most trees survive by either constant irrigation or extremely deep roots.
It’s a pretty unique environment for North America as well. The building takes up an entire city block so it can hold the weight of what is basically a boreal forest on top. The building is almost 60 years old so the trees are quite sizable. And there are a lot of them! I can see 9 from my window and that is not close to all of them.
