Outdoors grade
How much outdoors does Lake Oswego have?
On conserved land, trails, park land and how close residents live to a park, Lake Oswego is ahead of 94% of U.S. towns, #11 of 142 in Oregon. All four inputs are above most U.S. towns; trail miles rank highest, park acres per resident lowest.

Water is 6% of Lake Oswego’s area (1 of 12 square miles), so every share here is of land; over land and water together, the conserved share would read 18%.
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.
