Outdoors grade

How much outdoors does South Arm Township have?

On conserved land, trails, park land and how close residents live to a park, South Arm Township is ahead of 51% of U.S. towns. Park acres per resident hold the grade up; the share of residents near a park pulls it down.

Water is 6% of South Arm Township’s area (2 of 33 square miles), so every share here is of land; over land and water together, the conserved share would read 3%.

How sure. Graded on any three of the four inputs instead, the letter would range from C to B+. 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.
