The City River Strategy is a billion dollar regeneration plan for the 31ha Parramatta River urban waterfront in Sydney's second largest metro centre. Prepared in consultation with community and adopted in May 2015, the strategy utilises $200 million of public spaces and cultural facilities on government land to catalyse adjacent mixed use urban development. Utilising tactical urbanism and biocity principles the plan unites a diverse range of active public places including an urban beach and water square with massing concepts for supporting hybrid architecture. Space is set aside for 10,000 people to celebrate on River Square and a new pedestrian link is included to connect Parramatta Square and the city rail station. The sister to Circular Quay, Parramatta Quay, enables a fast ferry link to Sydney city. Dutch and German flood engineering technologies are deployed to enable safe occupation of the flood zone by retail and cafe uses.
