Land Development

The City of Cockburn is expanding rapidly due to land development of Greenfield areas as well as infill development within established suburbs. Some key developments the City is currently managing include Cockburn Central West (the Docker’s New Training Ground) and subdivisions such as Calleya Estate, Cockburn Coast, Port Coogee Marina Village, Eliza Ponds and Vivente. As it is currently estimated that the municipality of Cockburn will have a population of 175 000 people by 2036 a lot more development is set to occur in our council.

Standard subdivision engineering process

Once a subdivision has received approval from the Western Australian Planning Commission or a development application has received approval from the City’s Planning Department the engineering process related to the development can commence:

  • 2 sets of A1 engineering design drawings and specifications sent for City’s review.

  • The City reviews documents and an Approval letter with conditions sent out.

  • Consulting Engineers advises the City of the works commencement date, Contractor’s name and contract sum.

  • City inspects all stages of works such as subgrade, sub-base, asphalting, kerbing, drainage and footpath works. 

  • Practical Completion Inspection with contractor and consulting engineer occurs at the completion of all stages of works. The 12 months Defects Liability Period starts after the Council accepts the works.

  • All QA documents and as constructed drawings are to be submitted for City’s record at the time of clearance of the development along with the Supervision Fee (1.5% of contract sum) and Maintenance Bond (2.5% of contract sum). The Maintenance bond is released after a successful inspection at the end of defects liability period.

Subdivision Guidelines and Standard Drawings

To help standardise the process, the City has produced the following design guidelines and standard drawings to encourage a straight-forward design process and faster approval time. City acknowledges that the Guidelines published by IPWEA (latest edition) are to be considered as the minimum standard for subdivision development. The below documents are subject to periodic change and constructive criticism will be appreciated. 

It is the responsibility of developers and consultants who work with development to ensure the document they are referring to is the most recent available. 

To facilitate this, the version number on the front cover will be updated every time a change is made to the document and a list of the changes made will be provided in the table of contents. 

Compliance with these documents in the design will result in a simpler design process and a quicker approval time.

The City of Cockburn appreciates innovation however approval for any variance should be sought before it is incorporated in the design.
