9 mature beautiful trees

I got an information that city is going to make a bigger parking at the Guelph Youth Music Center for some unknown reason. During the process (which support automobile use, instead limit it for our mutual advantage) you are going to cut down 9 mature beautiful trees. The person who told me about the planed devastation notifies that he proposed optional parking construction to save the trees.

Could you say me why the devastation of our green lungs and decoration cannot be avoided?AS
