Outdoors grade

How much outdoors does San Anselmo have?

On conserved land, trails, park land and how close residents live to a park, San Anselmo is ahead of 94% of U.S. towns, #130 of 847 in California. All four inputs are above most U.S. towns; the share of residents near a park ranks highest, park acres per resident lowest.

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.
