Olmsted divided park into two categories – neighborly and gregarious. Below grade connections made pedestrian connections separate and inconspicuous from carriage traffic.
The Greensward plan design was a big one in 1858 because it won the design competition in that year, this plan defeated the design proposed by Egbert Viele which had been previously accepted by the commissioners of the Central Park.
