How much outdoors does San Francisco have?
On conserved land, trails, park land and how close residents live to a park, San Francisco is ahead of 94% of U.S. towns, #137 of 847 in California. Trail miles hold the grade up; park acres per resident pull it down.
Among the 400 U.S. cities of 100,000 or more, San Francisco ranks #41 on Outdoors.
Water is more than half of San Francisco’s area (185 of 232 square miles), so every share here is of land; over land and water together, the conserved share would read 5%.
Park acres per resident are where San Francisco trails most U.S. towns: 7.5 per 1,000 against 12.6 typical, since 826,079 people share 6,234 acres.
