How much outdoors does Grand Isle have?
On conserved land, trails, park land and how close residents live to a park, Grand Isle is ahead of 86% of U.S. towns. Park acres per resident hold the grade up; the share of residents near a park pulls it down.
Few Louisiana towns conserve much land (a typical one, 1%; the U.S., 4%), so Grand Isle’s 8% is ahead of 93% of Louisiana towns, while its trails per square mile lead 98% of them.
Water is 22% of Grand Isle’s area (2 of 8 square miles), so every share here is of land; over land and water together, the conserved share would read 6%.
