How much outdoors does Kailua have?
On conserved land, trails, park land and how close residents live to a park, Kailua is ahead of 76% of U.S. towns, #31 of 93 in Hawaii. Trail miles hold 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 Kailua’s 13% is ahead of 49% of Hawaii towns, while its trails per square mile lead 79% of them.
Water is 27% of Kailua’s area (3 of 11 square miles), so every share here is of land; over land and water together, the conserved share would read 10%.
