So Sorry to know about the Tree. Dont worry it will grow back soon. As long as it was not pulled out from the ground the tree will still grow. As the climate is changing the leaves are all going dry and falling off making the roads dirty. The MMAA trim such trees so that it grows back all again fresh & healthy with new leaves.
Also it avoids the growth of some mites that harm the tree.

Within a couple months your trees will sing again !!
