Yes — flood overlay is one of the most significant planning constraints across Logan. The Logan and Albert rivers both have large inundation footprints, and parts of Beenleigh, Eagleby, Waterford, and Bethania are meaningfully affected. Depending on where your block sits, this can dictate minimum habitable floor levels, car park slab heights, and which materials can be used below the flood line. We assess this at the very start of the design process so it's never a surprise.
