9 year old synthetic turf field (FieldTurf USA)
A grass field was removed to showcase the idea that synthetic turf was safe, economical, and durable.
In 20??, the field's conversion was the first public private partnership project between the City of San Francisco and the City Fields Foundation -- removing ?? acres of city grass parks and replacing them with synthetic turf, covered with ground up tires. Their ventures would benefit their business associates over $50,000,000.
