How much outdoors does Hahnville have?
On conserved land, trails, park land and how close residents live to a park, Hahnville is ahead of 28% of U.S. towns, #79 of 162 in Louisiana. Trail miles hold the grade up; park acres per resident pull it down.
Few Louisiana towns conserve much land (a typical one, 1%; the U.S., 4%), so Hahnville’s under 1% is ahead of 17% of Louisiana towns, while its trails per square mile lead 98% of them.
Water is 15% of Hahnville’s area (1 of 7 square miles), so every share here is of land; over land and water together, the conserved share would read under 1%.
