The $14 million Landsdale East Primary School was proposed for a 3.75ha site on Kingsway and Pomodora Avenue to open in 2017.
The metropolitan northwest Joint Development Assessment Panel (JDAP) deferred the application because of a lack of information and concerns about car parking.
To cater for 760 students, the school needs 191 car parking bays but 142 were proposed " a shortfall of 49 " in order to retain bushland on the site.

"Given the location next to a busy road, I have already raised with both (Wanneroo) Council and the Department (of Education) the need for additional vigilance about traffic management and safety. It beggars belief these basics have not yet been factored in to the satisfaction of the DAP."
Landsdale Residents' Association president and Wanneroo councillor Domenic Zappa said residents had been lobbying for a school in the area for many years.
"Any additional delay may impact on the timetable, with the school due to open at the start of 2017," he said.
"With the enormous population growth in the area, demand is already high.
"I am hopeful that the next appearance before the development assessment panel will be soon and that the department is fully prepared to address concerns and queries."
