In 1966 the MRPA commenced a review of the Region Scheme with the intent of determining whether the future expansion of Perth should occur via "clusters" or "corridors". Theoretical debate over the merits of these two theories occurred throughout the late 1960s, and similar plans had been prepared for Sydney and The MRPA eventually settled on the application of corridor planning principles as the right approach for Perth in February 1969, and commenced detailed planning of the Armadale corridor before moving on to complete a plan for the whole of the metropolitan area by November 1970. The intent of the Plan was to accommodate future development of the metropolitan region whilst maximising economic efficiency. In this, it complimented the Perth Regional Transportsation Study published in January 1970 which concluded that "corridor planning provides the most economic transport system for the Region".

The Plan included a number of key predictions and recommendations as follows:
Large areas of open space to be located between the corridors.
The development of the sub-regional centres of Armadale, Joondalup, Whitfords, Rockingham and Midland.
A comprehensive, high-speed bus service to provide public transport to the region. This was to include bus lanes in existing railway reserves converging on the CBD.
Suburban train facilities to be progressively suspended between Perth and MIdland, Armadale and Fremantle.
Academic Dave Hedgecock describes the 1960s as a time when academic and professional consensus around metropolitan planning began to collapse. The Corridor Plan represented a paradigm shift away from “planning by design” to “planning by science” and never achieved the level of support enjoyed by the earlier Stephenson-Hepburn plan. It remained controversial through its preparation and period of operation. Almost immediately following the adoption of the plan, the state government appointed Paul Ritter to provide comment on the plan. He was critical, and proposed an alternative directional grid pattern of development. His report led to the initiation of an Honorary Royal Commission by the Legislative Council in 1971. The purpose of the commission was to enquire into and report on the preparation of the Corridor Plan. The Commission completed its investigation in 1972. The commission concluded that the corridor planning concept was sound in principle, but identified a number of deficiencies in the report presentation and proposed implementation. The findings of the commission did not lead to a formal review of the plan, and the MRPA published its own report defending the Plan against criticism. Passenger services on the Fremantle line were suspended on 1 September 1979, in line with the recommendations of the Plan. The closure led to a public backlash and the service was reinstated on 29 July 1983 following a change of government. A review of the Plan commenced in 1985 due to deficiencies in the population projections which had anticipated a metropolitan population of 1.4 million by 1989--approximately 250,000 short of the actual numbers. The Plan also incorrectly identified sub-regional centres as the primary source of non-CBD based employment growth, when in reality most employment growth occurred in the inner City suburbs around the central area.
