The open spaces will be created in the next decade as Milton Keynes develops into five surrounding areas. The Parks Trust, a charity set up in 1992 to manage the town's open spaces, will take on the new parkland following its establishment by the sites' developers.
Public open space provision is planned in Milton Keynes' Western and Eastern Expansion Areas, Tattonhoe Park and Kingsmead South, Stantonbury Park Farm and Newton Leys.
The Parks Trust's chief executive, David Foster, said: "We're working closely with the developers, landscape architects and council to make sure the open space links in well with the existing open space and it is designed to a really good standard."
When the trust takes on the new open spaces it will be given an endowment by the developers to ensure it can look after the parkland in perpetuity.
"We need to calculate the right amount to be able to maintain the new parks and open spaces, and we'll be doing that over the next few months," Foster said.
