Surry Hills is defined by its topography: – sand dunes, swamps, a sandstone plateau and a ‘shale cap’ that’s weathered into a hard blue clay that made the area impossible for farming and would later cause drainage problems. Today’s Crown Street sits on top of the plateau of sandstone which runs north-west between Woolloomooloo and the sandhills in the vicinity of today's Central Station.

We’re planning to upgrade Crown Street and would love to hear your thoughts. Feedback closes 19 September.
