Yerriyong zoning & planning overlays
A planning-constraint profile of Yerriyong
(Shoalhaven, NSW) - 127.6 km², mapped from live council and
state overlay data. This suburb is highly constrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.

Constraint readout
127.6 km² - this suburb is highly constrained on the overlays we could measure - no flood mapping covers this suburb, so this is not a suburb-wide verdict.
Elevation hillshade with street names, clipped to Yerriyong's boundary, with the bushfire and environmental overlays drawn on top. Amber hatching is the published aircraft noise (ANEF) contour. Magenta is where aircraft were observed in the sampled period, brightest below 3,000 ft. No flood layer is drawn because we hold no flood mapping for this area.

Aircraft noise and flight paths over Yerriyong
Two different things, kept apart on purpose. The ANEF contour is the planning instrument - a forecast published per airport that planning schemes use to control noise-sensitive development. Observed overflight is what a sampled aircraft-tracking feed actually recorded over the suburb - where aircraft flew, how low and how often.
Inside an aircraft noise contour
2% of the suburb's land sits inside a published ANEF or airport-environs contour. Contours vary street by street, so whether a particular lot is inside one needs a property-level check.
Highest contour present
Under AS 2021, land between ANEF 25 and 30 is generally unacceptable for new houses; 20 to 25 is conditionally acceptable with noise attenuation. The contour is a forecast, not a measurement at any one house.

Observed overflight - sampled 4 Sep to 26 Sep 2026
typical observed square 1 a day
Night movements: observed, lowest 500 ft - night is sampled as often as day, but night traffic is light, so this is a floor and no rate can be put on it.
Traffic is sampled rather than watched continuously, so every figure is a floor: aircraft not captured between samples are not represented. Rates are per 500 m square - the busiest square in the suburb, not a count of flights over the suburb - and a square is only rated where enough traffic was seen to measure it. Altitudes are above mean sea level. Flight paths change with runway use, weather, season and airspace design. This is a record of observed traffic; it is not a noise contour and not a planning control.

How Yerriyong is zoned
Buying in Yerriyong? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 127.6 km², Yerriyong is highly constrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. Of what is mapped, 100% is flagged bushfire-prone. The dominant land-use zone is Rural Landscape. The median lot measures about 142,594 m² across 146 parcels.

Is Yerriyong flood-prone?
We don't yet hold flood mapping covering Yerriyong, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. Shoalhaven is the authority to check for flood mapping in this area.
Is Yerriyong bushfire-prone?
Around 100% of Yerriyong is mapped as bushfire-prone, compared with a Shoalhaven average of 90%.
Is Yerriyong affected by aircraft noise?
About 2% of Yerriyong sits inside a published aircraft noise contour, and the highest contour present is ANEF 25 - under AS 2021, land above ANEF 25 is generally considered unacceptable for new houses, and 20-25 conditionally acceptable with noise attenuation. ANEF contours are forecasts published per airport and used to control noise-sensitive development; they are not a measurement at any one house, and a property can sit under a flight path and outside every contour.
Is Yerriyong under a flight path?
Aircraft were observed below 3,000 ft over about 70% of Yerriyong, and over about 78% at any altitude up to 10,000 ft, in the period sampled (4 Sep 2026 to 26 Sep 2026). The lowest measured aircraft was at 500 ft, with an average of 1,500 ft. At the busiest point in the suburb about 38 aircraft a day were recorded passing over one 500 m square. Traffic is sampled rather than watched continuously and flight paths change with runway use, weather and season; the ANEF contour is the planning instrument.
What is the zoning in Yerriyong?
The dominant planning zone in Yerriyong is Rural Landscape, though the suburb also includes National Parks and Nature Reserves and Environmental Management.
Does Yerriyong have heritage-listed places?
No heritage-listed places are on record within Yerriyong.
What is the typical lot size in Yerriyong?
Across 146 surveyed parcels in Yerriyong, the median lot size is about 142,594 m². There are also 3 registered easements mapped in the suburb.
