Outdoors grade
How much outdoors does Islip have?
On conserved land, trails, park land and how close residents live to a park, Islip is ahead of 96% of U.S. towns, #60 of 758 in New York. All four inputs are above most U.S. towns; conserved land ranks highest, park acres per resident lowest.

Among the 400 U.S. cities of 100,000 or more, Islip ranks #27 on Outdoors.
Water is 37% of Islip’s area (60 of 163 square miles), so every share here is of land; over land and water together, the conserved share would read 14%.
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.
