> The price is worth paying

I looked up prices as I was initially in doubt if this was a good cost-benefit. This article claims that New York Cty trees have a lifetime cost of ~3,500 USD (in gardening). I was under the impression of a much higher annual cost, so I was way off in my initial reasoning.

This report puts annual gardening costs of Portland trees at around 40usd [1]

These numbers do not include added road, curb and sidewalk maintenance incurred by the tree, as far as I can tell.
