Public open space refers to lands that are publicly owned, publicly used, and publicly accessible. The amount of public open space per neighborhood varies greatly across San Francisco.
The Open Space Element of the City's General Plan (as amended in 1991) requires the City to preserve and protect the Significant Natural Resource Areas (Policy 13). The policy identifies the following criteria used to determine a Significant Natural Area:
In San Francisco these communities may include oak woodlands, creeks, lakes, grasslands, dunes, scrub and rock outcrops. In many cases these nature preserves are the only places where wildlife such as the Red-tailed Hawk, Gray Fox, Great-horned Owl, and San Francisco garter snake still reside, reproduce and play.
To calculate the percent of neighborhood open space that is natural area, total square feet of natural area were divided by the number of square feet that was designated as natural area.
Not all significant natural areas may be accounted for in this data. Significant natural areas not publicly owned have not been accounted for.
