Los Angeles parks are in trouble. In May, the Trust for Public Land ranked Los Angeles 93rd out of 100 major U.S. cities for parks, its lowest ranking ever and the seventh consecutive year of decline. The recently completed Los Angeles Park Needs Assessment, where we both served on its steering committee, helps explain why. The City spends just $92 per resident on parks, less than a third of what peer cities spend. One in three Angelenos lacks a park within a 10-minute walk of home.
