34 Elm St - Traffic Assessment - Rev C

34 Elm St, Cooroy




    1. Introduction
In September 2018, 360 Civil Consulting were engaged to undertake a sight distance assessment
for the accesses to the proposed shopping centre (with a minor residential component) at 34 Elm
St, Cooroy (Lots 4-6 on RP72698) and assess the impact the development will have on Diamond
Lane and the Diamond Lane / Elm St intersection. The original proposal contained two accesses
onto Opal St. The access to Diamond Lane was limited to the residential component (two unit
dwellings).
As of April 2019 the proposed development layout has been amended and the revised proposal is
contained in Appendix A. The amendments involve the removal of the western access onto Opal
St and the removal of the residential component. It is now proposed for all commercial vehicles to
exit via a left exit only onto Diamond Lane. It is proposed that a boom gate system be installed to
ensure that Diamond Lane access is restricted to commercial vehicles (exiting) only. Details of the
boom gate system are included within this report.
The existing buildings have recently been demolished and the site is now vacant. The previous use
was for the Cooroy Motel. The proposed shopping centre consists of 9 shops.
To complete this assessment a site inspection was originally undertaken on the 29 August 2018.
The information contained in this report has been updated to reflect the amended development
layout contained within Appendix A.

    2. Sight Distance Assessment
The proposed development is bounded by Diamond Lane to the north, the Cooroy Sports Hub to
the east, Opal St to the south and Elm St to the west.

It is proposed that the development has a single two-way access to Opal St and an exit only for
commercial vehicles only via Diamond Lane. Opal St and Diamond lane are both classified as Local
Streets under Council’s Planning Scheme.
