These departments will include governing, planning and design, serving, building and maintaining, and growing and activating, to reflect the core functions of the City.
Chief executive Gary Stevenson said given Perth was in the midst of dramatic change, with new developments and the introduction of the City of Perth Act to State Parliament imminent, the way the City worked needed to reflect that.
�The mid-structure is designed to consolidate like functions, elevate emerging priorities and optimise span of management,� he said.
�This historic reform process will ensure an increased focus on enhancing customer service and development within the City.�
Although there would be some redundancies, Mr Stevenson said the aim of the restructure was not cost cutting.
Earlier this year, he announced the reactivation of the 2014-16 Organisational Development Plan proposal to complete a significant Organisational Structure Review.
Last week, councillors endorsed the new organisational structure at a special council meeting.
The reform was driven internally and all staff were consulted and given opportunities to make submissions.
