Resident says aircraft noise levels will be unacceptable
MUNDARING Shire is objecting to Shire residents being exposed to louder and more frequent aircraft noise.
Councillors revised a draft letter by Shire staff to Perth Airport chief executive Kevin Brown after re- ceiving an invitation to comment on the airport’s major development plan.
The Shire’s letter noted the social and economic benefits of airport expansion, but drew attention to the impact of noise exceeding N65 ( noise decibels) in foothill suburbs.
“When the new runway opens, exposure to aircraft noise will be unchanged for most metropolitan areas. For some there will be a reduction, while for others there will be an increase. Over time, the number of flights will grow in all areas,” the letter said.
Mapping shows Parkerville, Hovea and Stoneville will experience less noise above N65, while the foothills suburbs of Swan View, Midvale, Helena Valley, Darlington and Greenmount are likely to be exposed to more noise above 65 decibels.
A normal conversation measures at 60 decibels and stress can be reduced by keeping levels below 50 decibels in areas where people need to do work requiring concentration, according to WorkSafe WA.
The Shire’s letter said the presence of existing aircraft noise over Hills suburbs should not be taken as tolerance for further noise.
It suggested the airport subsidise mitigation measures for those exposed to greater impacts.
A council report said there were community concerns about a new flight path over Helena Valley, Boya, Darlington, Glen Forrest and Mundaring.
The new runway is intended to be operational between 2023 and 2028.
The council said the timeframe suggested “substantial modifications” to the project were unlikely following the consultation period.
The Shire asked for studies to examine the impact of the proposed closure of Grogan Road, which was the most direct access to the airport for Hills residents.
