The American Parks Database
NRDC's Kaid Benfield takes a look at this year's report.
"The 85 largest U.S. cities have more than 1.4 million acres of city parks, according to data released earlier this month by The Trust for Public Land. The city park systems profiled in 2010 City Park Facts serve 58 million urban residents, offering 11,160 playgrounds, 9,167 ball diamonds, 1,349 swimming pools, 514 dog parks, and 400 public golf courses, among other facilities.
The report includes statistics on urban park acreage, spending, staffing, and facilities. TPL releases the data annually through its Center for City Park Excellence."
