Water is 9% of Marissa’s area (1 of 8 square miles), so every share here is of land; over land and water together, the conserved share would read under 1%.
How sure. Graded on any three of the four inputs instead, the letter would range from C to B+. 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.
