2Vegas, if the whole community had a landscaping overhaul, chances are it was in the works for a long time. I would start with the homeowner board, if not satisfied go to the next association meeting. Ask to see the notes where this was decided.
If they have all of this then ask for permission to plant a larger tree and some bushes around the window. Unless they did this on all the buildings chances are you can re-plant.
Some condo communities do massive overhauls of landscaping on a rotation basis.
