Outdoors grade
How much outdoors does Port Republic have?
On conserved land, trails, park land and how close residents live to a park, Port Republic is among the top 1% of U.S. towns. All four inputs are above most U.S. towns; park acres per resident rank highest, trail miles lowest.
A+

New Jersey towns conserve more land than most (a typical one, 11%; the U.S., 4%), so Port Republic’s 40% is ahead of 93% of New Jersey towns, while its trails per square mile lead 46% of them.
Water is 13% of Port Republic’s area (1 of 9 square miles), so every share here is of land; over land and water together, the conserved share would read 35%.
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.
