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.
