(1) The issue of traffic noise at this location was raised with Main Roads following an approach from a resident of River Road. At the request of the resident, noise testing was not conducted at River Road, but at a property in Dunstone Road which is closer to Tonkin highway. Noise measurements were undertaken in March 2007 at the Dunstone Road site and produced a mean traffic noise level of 68 dB (La10(18 hour)). This result is typical of that experienced at many residences located in close proximity to major arterial roads in Perth with significant amounts of traffic such as Leach, Great Eastern and Roe Highways.
(2) The results of noise measurements taken in March 2007 at Dunstone Road are submitted for tabling [ See tabled paper no.].
(3) The March 2007 results are the most recent.
(4) No further additional information is being sought.
(5) - (7) Main Roads is preparing a management plan to address extensive traffic noise across Perth's primary road network which includes noise testing at numerous locations across the road network. The plan will focus on noise reduction treatments that can be implemented to reduce noise at the most affected locations on a priority basis. Public input will be a key part of identifying suitable criteria for prioritising locations for installation of treatments.
