Maryland towns of 2,500+ (261)Ahead of 83%
Maryland towns conserve more land than most (a typical one, 9%; the U.S., 4%), so Overlea’s 10% is ahead of 55% of Maryland towns, while its trails per square mile lead 87% of them.
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.
