Outdoors grade

How much outdoors does Hardwick Township have?

On conserved land, trails, park land and how close residents live to a park, Hardwick Township is among the top 1% of U.S. towns. All four inputs are above most U.S. towns; park acres per resident rank highest, the share of residents near a park lowest.

A+
OutdoorsA character grade: shown, never part of Hardwick Township’s overall grade.
All U.S. towns we grade (21,298)Among the top 1%
LessMore

New Jersey towns conserve more land than most (a typical one, 11%; the U.S., 4%), so Hardwick Township’s 70% is ahead of 100% of New Jersey towns, while its trails per square mile lead 94% of them.

How sure. Graded on any three of the four inputs instead, the letter would still be 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.
