The estate has been developed over the past six years despite the unfinalised structure plan.
Peet general manager Paul Lakey said Shorehaven estate already had almost 1500 residents.
At the City of Wanneroo council meeting on April 28, councillors approved modifications required by the WAPC for the plan, which covers the 241ha in north Alkimos.
The council report said there had been �extensive negotiation� between the WAPC and developer and numerous changes, although subdivision approvals had been given in the interim.
CLE Town Planning and Design director Jane Bennett said the structure plan was first advertised for comment in 2009 and 1400 lots had been created so far.
�We are about half-way through the project,� she said.
Mr Lakey said finalising the plan would �remove any final uncertainty� and allow development to continue �through orderly and proper planning processes�.
He said being the first development in the area had challenges and benefits, and had helped deliver infrastructure such as gas and water pipelines.
Mr Lakey said the foreshore park, which opened in December, was an example of the amenity that would be used by the wider community.
�This final step allows us to move forward with delivery of community infrastructure and employment opportunities,� he said.
Mr Lakey said they hoped the Shorehaven Christian Grammar School would open in January, 2017.
Ms Bennett said final approval would help the estate achieve employment self-sufficiency, creating 630 to 800 jobs, rather than the 85 required.
She said earthwork on the eastern section would �begin immediately�
The biggest change to the plan between 2009 and 2015 was the removal of a proposed train station, at the Public Transport Authority�s request, and surrounding transit precinct.
The recommendation to accept the changes and approve the plan without further public consultation was carried unanimously without discussion.
