Balancing housing density with the need for trees

Cities across the nation and the world struggle with the dual challenges of building enough new housing for growing populations while also growing the tree canopy that makes that housing livable. This struggle is more apparent in Seattle than many people probably imagine. And yet, there are solutions within the city itself, as well as in communities far beyond Seattle's city limits like Bellevue, Washington; Bozeman, Montana; and even Milan, Italy.
