Water is more than half of Cudjoe Key’s area (5 of 10 square miles), so every share here is of land; over land and water together, the conserved share would read 26%.
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.
