In 1990, Concord Pacific was given permission to build 7,650 residential units on the Expo lands they purchased from the province. Part of the agreement was a requirement for 2.75 acres of park for every 1,000 residential units. Lot 9 (Creekside Park - the land northwest of Science World) was part of this original commitment. The actual wording of the agreement required the development of Creekside Park “when either lots 6A or 6C were rezoned for development”.
