New homes built in an upcoming Brisbane inner-city development could experience flight noise levels of up to 70 decibels, Brisbane Airport has warned.
The airport corporation has also pleaded with the Brisbane City Council to ensure future homeowners are aware of the noise levels and restrict them from making aircraft noise complaints.
Currently, there are plans to build up to 855 homes in the $63 million, 20-hectare Bulimba Barracks site – a former US Army base from WWII – all of which will fall under Brisbane Airport’s new flight paths.
Ahead of the proposed redevelopment of the site by Shayher Group, Brisbane Airport Corporation (BAC) has submitted a response to Brisbane City Council, urging the council to ensure residents are aware of the noise pollution in the area.
The airport said it has “significant concerns”, given that a third of the proposed development falls into the airport’s Australian Noise Exposure Forecast contours – meaning they are the most exposed to aircraft noise, and homes need to be built with additional noise insulation.
According to a spokesperson for BAC, “Noise modelling for Brisbane Airport indicates the whole Bulimba Barracks site falls within the 60 decibel (dB) noise contour, meaning most aircraft that overfly the area will generate noise above 60dB, and in some parts of the site, aircraft noise will be above 70dB.”
BAC added in its submission to the council that “inappropriate development” near the airport could “result in unnecessary negative impacts on community amenity and constraints on airport operations”.
It comes after existing residents of Bulimba, as well as numerous inner-city suburbs including New Farm, Teneriffe and Hawthorn, have spent months lobbying and protesting against excessive aircraft noise pollution over their homes following the introduction of Brisbane’s second parallel runway.
The increasingly-frustrated residents claim Brisbane Airport’s new flight paths have not met the expectations set in consultation with the community prior to the runway’s approval.
Brisbane City Council city planning committee chair Adam Allan said that aircraft noise will be taken into consideration as the council assesses the proposed development, however added that “it is not possible to restrict future noise complaints”, as the airport has requested.
While there is no regulation specifying maximum flight noise levels over residential suburbs, a plane flying overhead at 70 decibels would interrupt a conversation inside a home, according to Airservices Australia.
A spokesperson for BAC noted the airport’s interest in high-density developments near the airport, given the airport currently operates without an imposed curfew, given that excessive community complaints could impact this.
“BAC considers it imperative that future owners are made aware of current and future aircraft operations at Brisbane Airport, and the implications of these operations,” the spokesperson said.
“BAC is seeking that Brisbane City Council considers the registration of a covenant on any new title within the development that protects the future operations of the airport from noise complaints in relation to this specific site.”
