I had same problem and called city. The answer is 须市政府批准. And most likely, the answer is no if the tree is healthy. It is by-law and you could be fined because tree locations fit for streetscapes. It is a bad policy for home owners. We pay property taxes and has no right on landscape design for safety of house and surrounding landscape.
There is recent lawsuit about tree location where tree demaged the foundation of a westend home.
