New Hampshire towns of 2,500+ (126)Ahead of 22%
New Hampshire towns conserve more land than most (a typical one, 19%; the U.S., 4%), so Seabrook’s 8% is ahead of 10% of New Hampshire towns, while its trails per square mile lead 18% of them.
Water is 7% of Seabrook’s area (1 of 10 square miles), so every share here is of land; over land and water together, the conserved share would read 8%.
How sure. Graded on any three of the four inputs instead, the letter would range from B 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.
