Psst...changes to noise corridors

In a rare government change that results in reduced costs for homebuyers. The draft transport noise corridor modelling provides greater sophistication in the noise protection responses that are required in development.

In many cases, the mapping change results in a reduced noise category that applies to new buildings, and therefore, reduced noise attenuation being required. The effect of this is to potentially reduce the cost of a new dwellings for home buyers.

The Institute, with members’ help, reviewed the proposed changes and operation of the current noise requirements. Key comments in our submission included:

  • The Queensland Development Code MP 4.4 - Buildings in a Transport Noise Corridor should be reviewed
  • That clarification is provided for what is required if the structure or building that is attenuating the noise level is removed by the development or some other cause
  • The corridor noise modelling be altered to reflect actual present noise levels not projected levels
  • Additional information should be provided on the assumptions that underpin the corridor noise modelling and its effect on upper levels of proposed buildings
  • An annual update be undertaken of the noise modelling to reflect changes in circumstances
  • A form of grandfathering of provisions be considered for properties along the Redcliffe Peninsula railway corridor or a transition period be provided to avoid substantial unheralded costs on home buyers in this area
  • Consideration be given to creating areas in which no noise attenuation is required
  • Further consideration be given to noise modelling in rural locations where ambient noise is low
  • That a review be undertaken of costs associated with noise attenuation to seek to achieve greater use of less costly noise attenuation options.
