How common is mapped flood risk across Kelvinhaugh properties?
Overlay percentages say how much land is constrained; these figures say how many properties are actually touched in a suburb-wide analysis of 73 Kelvinhaugh properties. No individual property result is identified on this page.
Lot-level readout
Flood-risk rating across all 73 properties
From LayeredGeo's lot-risk engine: council flood overlays, historical flooding and terrain, resolved to each individual lot in Kelvinhaugh.
Aircraft noise and flight paths over Kelvinhaugh
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
16% 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 at ANEF 30 and above is generally unacceptable for new houses and most noise-sensitive uses. The contour is a forecast, not a measurement at any one house.
