23 We next refer to the question of an acoustic barrier on the Mail Centre land and SEPPN-1. In our interim decision, we made comment on the desirability for an acoustic barrier even if the standards of AS2107 could be met. That was on the basis that the evidence before us was that the Mail Centre would breach SEPPN-1 if the units in the form proposed were erected even with attenuation works to the units being implemented. That remains the case in relation to some aspects of the development.
24 At the resumed Hearing, Mr Gobbo stated that APC had not determined if it would seek for a barrier to be erected although it should be APC's choice as to whether it would proceed. Mr Pitt responded that APC has had long enough to decide whether it would want a barrier and has not indicated that it would undertake ameliorative works. Thus M1 Preston would seek the Tribunal's permission pursuant to Section 114(3) of the Victorian Civil and Administrative Tribunal Act 1998 to withdraw its open offer dated 7 March 2005. That offer was $200,000 plus GST. Costs of acoustic barriers can vary widely but the evidence before us was that a single wall with raked upper section may cost around $200,000 but possibly be higher.
25 We are not persuaded to grant leave for the open offer to be withdrawn.
26 We find that an acoustic barrier on the APC land is warranted to assist to achieve a reasonable noise environment for occupants of the proposed dwellings. Although bedrooms may be AS2107 compliant with west-facing bedroom windows closed the same is not the case if such a window was to be opened. There is also the likelihood that the achievement of AS2107 will be to levels at the upper end of the available range, ie. at the "maximum" level rather than the "satisfactory" level potentially still giving rise to nuisance as noted in Mr Burton's evidence. Moreover, SEPPN-1 would not be met even with some of the changes to the plans we have discussed above and further the introduction of an acoustic barrier would assist to achieve compliance for external balconies that we have not canvassed above. We therefore consider there to be a just and fair basis to require the permit holder to facilitate APC being compliant with SEPPN-1 given the imposition of a large residential complex into an otherwise predominantly (but not wholly) non-residential setting.
27 That is despite a barrier causing some disadvantage to APC.
28 It could fairly be asked why direct changes to the plans if an acoustic barrier is to be erected? Because we have no guarantee that a barrier will be erected as no consent to such works on APC land has been given by APC. We have no power to direct APC to give its consent.
29 We heard oral submissions from Mr Gobbo, Mt Pitt and Mr Evans as to whether a condition requiring the erection of a barrier would be lawful based on recent amendments through the Planning and Environment (Development Contributions) Act 2004 that address development contributions. Those amendments are important to a consideration as to whether a contribution can still be directed to be sought by way of a permit condition in the circumstances of this case. The amendments have been introduced since our interim decision. It was common ground between the parties that the relevant section is Section 62(5) of the Act that requires:
