Outdoors grade
How much outdoors does Greenwich have?
On conserved land, trails, park land and how close residents live to a park, Greenwich is ahead of 83% of U.S. towns, #72 of 155 in Connecticut. All four inputs are above most U.S. towns; conserved land ranks highest, park acres per resident lowest.

LessMore
Connecticut towns of 2,500+ (155)Ahead of 54%
Connecticut towns conserve more land than most (a typical one, 15%; the U.S., 4%), so Greenwich’s 13% is ahead of 38% of Connecticut towns, while its trails per square mile lead 34% of them.
Water is 29% of Greenwich’s area (20 of 67 square miles), so every share here is of land; over land and water together, the conserved share would read 9%.
How sure. Graded on any three of the four inputs instead, the letter would range from A− to A. Trails and many small parks come from OpenStreetMap, mapped by volunteers, so coverage varies from town to town; the half mile is a straight line from each census block, so a river or highway in the way isn’t counted against it.
