By replacing asphalt, the new playground manages nearly half a million gallons of stormwater annually, improving the health of local waterways. At various public school sites in New York City, green infrastructure components proposed by The Trust for Public Land have included small green roofs on storage sheds, rain gardens, rain catchment systems, and artificial turf fields with a gravel base that allow stormwater to pass through and be absorbed into the ground. With such improvements, green infrastructure components can capture at least the first inch of stormwater that falls on the playgrounds each time it rains.
