MUNDARING Shire staff are recommending councillors support the Perth Airport major development plan, despite highlighting noise concerns.
An administrative report, including a letter in support of the new runway and development plan, will be presented at Tuesday’s council meeting for consideration.
The report found that although the project would have an overall positive impact on the community, administration objected to noise impacts on residents.
“It is recommended that where the project would result in residents being affected by louder/more frequent aircraft noise than they are currently experiencing, Perth Airport be required to provide appropriate mitigation of these impacts,” the report said.
Two noise measurement methods conflicted with administration’s decision.
Under the Australian Noise Exposure Forecast (ANEF), a planning tool to dictate land use and housing density in the airport flight path, the number of resident’s exposed to aircraft noise would decrease overall.
When measured against noise decibels (N65), residents in Swan View, Midvale, Greenmount, Boya, Darlington and Helena Valley would experience more noise events 65dB or more.
According to WorkSafe WA, a normal conversation measures at 60dB.
“Therefore, depending on the metric used, the project is anticipated to have both less (ANEF) and more (N65) noise impact on Shire residents,” the report said.
“This results in a difficult situation for the Shire in that the contraction of the ANEF is supported but the N65 expansion is not – and both results arise from the same Project.”
The report recommends objecting to the increase of louder or more frequent noise than is currently experienced and suggest Perth Airport be required to subsidise mitigation measures for those exposed.
The report also includes community concerns about a new flight path over Helena Valley, Boya, Darlington, Glen Forrest and Mundaring but said the flight path is expected to be used “infrequently” with less than 10 events per day.
The report will be up for discussion by councillors at the Shire of Mundaring council meeting, Tuesday, August 14, 6.30pm in Council Chambers.
