New Jersey towns conserve more land than most (a typical one, 11%; the U.S., 4%), so Helmetta’s 36% is ahead of 90% of New Jersey towns, while its trails per square mile lead 63% of them.
Water is 6% of Helmetta’s area (0 of 1 square miles), so every share here is of land; over land and water together, the conserved share would read 33%.
NoteFew parks or trails are mapped in Helmetta. OpenStreetMap is mapped by volunteers and coverage varies from town to town, so a town with unmapped parks scores low on 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.
