The City Council on Thursday approved two motions on parking and residential density in the University neighborhood. They are aimed at establishing an Interim Zoning District for the Uptown area near Tulane and Loyola with more stringent parking requirements than the rest of the city. It’s an unusual move for a council that normally prioritizes the creation of housing, particularly affordable housing, over parking. But the Uptown area near Tulane and Loyola universities has an unusual problem, with investors buying up homes and converting them to high-end multi-unit rentals marketed to students. “What’s occurring right now, particularly in the Maple neighborhood, is that doubles are being converted into dormitories,” said District A Councilman Joe Giarrusso at Thursday’s meeting.
