What Bayside Council publishes
Bayside Council publishes an online map with a flood layer. You search the address in the viewer, turn the flood layer on, and read what is drawn over the lot against the legend. It is the council's own mapping, so it is the primary source; the state layer on the Planning Portal is a copy that may lag it.

How to check an address in Bayside Council
- Open the NSW Planning Portal Spatial Viewer, search the address, and turn on the Hazard group's Flood Planning layer. A shaded lot means the council's planning instrument applies flood related development controls to it. An unshaded lot means the state dataset holds nothing for it, not that the council's study holds nothing. The flood guide explains that layer in full.
- Open the council's online map from the link above, search the street address, and switch on the flood layer (it may sit under a hazards or planning group). Read the legend: the colours usually distinguish the flood planning area from larger, rarer floods.
- Read the flood notation on the section 10.7(2) planning certificate attached to the contract. It states whether flood related development controls apply to the lot, in the council's own words. Our 10.7 guide says what else it does and does not contain.
- Read the NSW SES Local Flood Insights page for the area for the flood history and warnings context the planning layers leave out.
What none of these tell you
Whether water has been inside this house. The planning layers and the council's maps describe modelled flood behaviour on the land, not what happened in a given year in a given room. Ask the agent and the neighbours directly.
What insurance will cost. Insurers run their own flood models. Get a quote for the address before exchange; a flood notation and a high premium do not always go together, and a clear lot can still carry a high premium.
The future. Councils revise flood studies, and the flood planning level can rise. A study dated ten years ago is describing the catchment as it was then.
Questions about flood risk in Bayside Council
Does Bayside Council have a flood map?
Yes. Bayside Council publishes an online map with a flood layer; the link is on this page. Search the address, turn the flood layer on and read the legend. The 10.7(2) certificate states the same thing as a notation.
How do I get flood information for a property in Bayside Council?
Read the flood notation on the 10.7(2) planning certificate attached to the contract, then use the council's own source linked on this page. If the council provides flood information on request, apply for it before exchange; a council fee may apply.
Is the state flood layer on the NSW Planning Portal the same as the council's mapping?
No. Since July 2021 councils are responsible for flood mapping in their area, and the Planning Portal's flood layer is a copy of what councils have contributed. A blank result there means the state dataset holds nothing for the lot, not that the council's study does. The council's own mapping is the primary source.
Does Prova replace Bayside Council's flood information?
No. The free check reads the state flood layer and names the flag. The A$19 report reads the council's map for the lot where the map allows it, or links the exact page, and puts the evidence beside the state layer's answer.
