Coffs Harbour flood map check
City of Coffs Harbour publishes its own flood mapping, and the Site Checker reads it for any Coffs Harbour address. The checker reads its adopted flood planning area, stitched from thirteen named studies from the Bonville Creek Flood Study 1995 to the Northern LGA Flood Study 2023, and its 1% AEP flood extent.

Is my Coffs Harbour property flood affected?
A Coffs Harbour property is flood affected for planning when any part of it is in the City of Coffs Harbour's flood planning area, and the council says every property in that area has flood information available. The Site Checker above reads the council's layers, the NSW Planning Portal map and the NSW SES extents, and shows each answer separately. The official answer is still City of Coffs Harbour's, and the questions below explain how to get it.
Where is the City of Coffs Harbour flood map?
The City of Coffs Harbour shows its flood planning area in its Online Mapping Tool. Its flood risk management plans and studies page covers Coffs Creek and Park Beach, Boambee and Newports Creek, the Upper Orara, Woolgoolga, Bonville, Pine and Middle Creeks, and Moonee Creek.
Which City of Coffs Harbour flood layers does the Site Checker read?
Every flood planning area polygon carries its study name and year, so a reading can say, for example, that the Coffs Creek Flood Study put the block on the map. The 1% AEP extent, on a service of its own, names eleven of the same studies.
The checker asks 2 layers: Flood Planning Area and 1% AEP flood extent. Every one answered a test query on 18 September 2026. A layer titled PROPOSED, an indicative flood planning area and a draft special flood considerations area are left out, because none is adopted.
What does the Coffs Harbour flood planning area mean?
It is the flood planning level extent, the land at or below the 1% AEP flood level plus a safety margin called freeboard, where the City of Coffs Harbour's flood controls apply. 1% AEP means a flood with a 1 in 100 chance of being reached or exceeded in any year. Because each polygon names its study, two neighbouring streets can rest on studies decades apart.
How do I get a flood certificate from City of Coffs Harbour?
Apply for a Flood Certificate through the City of Coffs Harbour's Flood Level Information request form, an online form on its get flooding information for a property page.
Why does the City of Coffs Harbour map differ from the state map?
They are drawn by different bodies for different jobs. The NSW SES Flood Database compiles flood extents from studies across the state, while City of Coffs Harbour's map is the one its planning controls are written against, and a flood planning area usually sits above the 1% AEP extent because it adds freeboard. A withdrawn LEP flood map on the Planning Portal shows as a former map with its date, never as a current control. The checker never merges the sources into one verdict, and where they disagree, City of Coffs Harbour settles it.
What else do people ask?
Does the Coffs Harbour flood map show how deep the water would get?
No. An extent says whether land is inside a modelled flood, not how deep or fast the water is. Flood levels in metres AHD (height above average sea level) come from City of Coffs Harbour, through a Flood Certificate.
If my Coffs Harbour block is outside the mapped area, can it still flood?
Yes. Coffs Harbour's thirteen studies run from 1995 to 2023, so the age of the modelling behind a lot depends on which creek it drains to. Land outside every map can still flood from overland flow no study has modelled, and a council can apply flood controls to land its published map does not show.
Is this the same as a section 10.7 planning certificate?
No. City of Coffs Harbour's section 10.7 planning certificate is the formal statement of the controls on a lot, including whether flood related development controls apply. Order one through City of Coffs Harbour certificate requests.
