County of Cumberland planning scheme


The County of Cumberland planning scheme, commonly known as the Cumberland Plan, was a land use and transport strategy developed by the Cumberland County Council in Sydney in 1948 and adopted by the Government of New South Wales in 1951. The plan's key elements were a green belt around Sydney and a radial motorway network, neither of which eventuated on their intended scale.
Though Sydney had had a comprehensive plan for its railways and a number of planned suburbs, including the city centre itself, the city as a whole had been allowed to grow organically. Suburban development in the early 20th century followed a 'starfish' pattern, closely tied to the railway and tramway lines that radiated from the centre. The McKell Labor government sought to create a framework for rapid metropolitan growth in the postwar period, and legislated in 1944 for the creation of a single Sydney-wide planning authority, governed by representatives of the various local councils. The Cumberland County Council commenced operations in July 1945.
The plan was resisted by NSW Government agencies, landowners and local residents and lost its patron when the county council was abolished in 1963.
The plan was eventually superseded by the Sydney Region Outline Plan in 1968.

The Green Belt

The most striking feature of the Plan was a vast green belt to hem in the city's sprawl. Beginning near Pennant Hills, the five-kilometre-wide belt would have curved through Western Sydney, encircling Baulkham Hills, Blacktown, Seven Hills and Liverpool before ending on the banks of the Georges River opposite East Hills. A non-contiguous section would then have covered the western Sutherland Shire, roughly bordered by the Georges River in the north and the Woronora River in the east. Motorists travelling north on the Cumberland Highway would have seen, with a few exceptions around Liverpool and Toongabbie, only green space to their left.
The Green Belt augmented an already extensive national parks system around Sydney, stretching from Royal National Park in the south to Ku-ring-gai Chase National Park in the north.
