Flood-risk rating across all 59 properties
From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Devon Park.
Aircraft noise and flight paths over Devon Park
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 aircraft traffic is a separate question from the contour.
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.
