How much outdoors does Aiea have?
On conserved land, trails, park land and how close residents live to a park, Aiea is ahead of 78% of U.S. towns, #26 of 93 in Hawaii. The share of residents near a park holds the grade up; park acres per resident pull it down.
Hawaii towns conserve more land than most (a typical one, 14%; the U.S., 4%), so Aiea’s 13% is ahead of 46% of Hawaii towns, while its trails per square mile lead 36% of them.
Water is 6% of Aiea’s area (0 of 2 square miles), so every share here is of land; over land and water together, the conserved share would read 12%.
