Water is 5% of Fairmont City’s area (0 of 7 square miles), so every share here is of land; over land and water together, the conserved share would read 34%.
How sure. Graded on any three of the four inputs instead, the letter would still be 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.
