Officials broke ground Wednesday afternoon on the McClure green space property.
The ceremony was the fourth of four over the past two weeks marking the start of work on the passive parks in south Forsyth.
County commissioners have approved a nearly $5 million contract with Georgia Development Partners to prepare the sites, which also include Echols Road, Old Atlanta and Harrison.
Among the features at the parks will be trails, pavilions and playgrounds.
The funding for the projects will come from 1-cent sales tax revenue, impact fees and the parks, recreation and greenspace bond voters approved in 2008.
The county hopes to open the four parks by the end of June.
