Shortly after the People Power Revolution in 1986, the Quezon City Parks Development Foundation (QCPDF) was established during the term of then Quezon City Mayor, Brigido Simon Jr. Under a tripartite agreement between the Quezon City government, National Historical Institute (NHI, now the National Historical Commission of the Philippines) and the National Parks Development Administration (NPDA), the NPDA was given jurisdiction over the 27 hectares park except a one hectare area covering the Quezon Memorial Shrine which is under the NHI.
