New Jersey towns of 2,500+ (468)Ahead of 84%
New Jersey towns conserve more land than most (a typical one, 11%; the U.S., 4%), so Upper Freehold Township’s 55% is ahead of 98% of New Jersey towns, while its trails per square mile lead 71% 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.
