Dublin City Council will have to complete a comprehensive traffic assessment if it plans to seek new permission for a pedestrian plaza at College Green, An Bord Pleanála chairman Dave Walsh has said.
Speaking after the board rejected an application last October, he said an updated and fully assessed traffic management plan would be needed.
"They were relying on information from 2014 and 2015 rather than thinking about the next five years and 10 years," he said. "I would expect that if it does [seek a new permission], what comes back in from Dublin City Council will be a far more comprehensive assessment. Where do the buses go? Can the quays take it? Will there be knock-on developments required to get buses back on to routes?"
He also welcomed a decision by the Supreme Court to hear a legal challenge to the Apple data centre, saying it would provide "clarity" to planning authorities and be of "great benefit" in interpreting complex EU and national law.
The board gave Apple the go-ahead to develop one data hall at Athenry in Galway in August 2016.
The tech firm intended to build eight halls over time, but the application only dealt with one hall and a connection to the national grid. The Supreme Court will hear an appeal from objectors, and decide if the board should have considered the impact of all eight data halls on the environment.
