To expand on Em's answer, the council's flood maps are pretty useless (refer to Lookout Place on the map, many homes in that street were flooded by Burpengary Creek but they are not marked on the map as it is only 1 in 100 year AEP). I have 1 in 250 year AEP maps if anyone is interested (email email@example.com) . Most of Narangba had no flood risk up until development occurred along Burpengary Creek. Burpengary Creek has always had a tendency to flood but back in the day, the area was all unoccupied bushland so no one noticed. Lookout Place, Moorhen, Mannikin and Hideaway close have all been effected by Burpengary Creek flooding. Maidenhair came close as well. Sideling Creek and Browns Creek also floods but they are more in the acreage areas of Narangba where no houses currently are so not a big deal.
