A city recreation department is considering a proposal to replace natural grass on its most heavily used sports fields with artificial turf. Proponents argue that artificial turf can be played on immediately after rain, unlike grass fields which must often be closed to prevent damage, that turf fields can host several times more hours of play per week without becoming worn or muddy, and that turf eliminates the need for regular mowing, seeding, and irrigation.
Based on a two-year trial in which one heavily used field was converted to artificial turf, the recreation department has concluded that converting its other heavily used fields to turf would increase the total hours of play available citywide and reduce the department's long-term field-maintenance costs, without increasing injury rates among players.
