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.
