 The area described as 'the central city' in Clause 21.08 of the "Melbourne Planning Scheme" is similar, but also includes the Docklands.There are several adjoining areas that have important functions that are sometimes included within the idea of 'the CBD' or the central city, such as Parliament House and the Treasury buildings on Spring Street, which are officially in East Melbourne, and Southern Cross railway station on Spencer Street, which is officially in Docklands.Other areas have in the last 30 years years become heavily developed with apartments, office buildings and important functions similar to the CBD, and are sometimes incorporated, such as the Docklands (with Docklands Stadium) to the west, and Southbank and South Wharf on the other side of the Yarra River.
