I agree and I would go one step further; I believe the city should mandate shade-tree lined streets. For example between the street and the sidewalk a tree every twelve feet where possible. All yards front and back capable of growing trees should be given tax incentives per tall tree grown. I would like to see as many tall shade-trees as possible living in New York City, not only are tree lined streets pleasant to look upon but the shade provided to the street multiplied by the NYC’s 120K blocks will lower the temperature of the city in summer.
