Colorado towns of 2,500+ (159)Ahead of 94%
Colorado towns conserve more land than most (a typical one, 7%; the U.S., 4%), so Niwot’s 39% is ahead of 97% of Colorado towns, while its trails per square mile lead 94% of them.
How sure. Graded on any three of the four inputs instead, the letter would still be 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.
