Hi dreads! What an awesome idea! I agree with Peachy that it's safer to ask. But if you do get permission, be careful about what you plant and where. My brother is a certified arborist, and he recommends not planting trees on the strip between the sidewalk and the street. It's hard on the trees, and can damage the sidewalk and street as well.

I would try to get advice from a local expert before going ahead. In the U.S. a county extension agent can be a good source of information about what varieties of trees and flowers are best to plant.
