As shown in Figure 1 below and the concept plans included as Attachment A & B, access to lot 4 can be
achieved via the existing crossover located at 22 Ghostgum Court.
The existing crossover is a non-standard geometry given it has a width of approximately 6.4m at the kerbline
and a separate 3.0m wide crossover for the dwelling at 22 Ghostgum Court. Presumably this additional
width at the kerbline was provided to allow a refuse collection vehicle to perform a 3-piont turn at the end of
the cul-de-sac. Whatever the reason, the as-constructed crossover can be used to provide a safe and
functional driveway for proposed lot 4.




                                    Figure 1 – Proposed Access to Lot 4


The following observations are made in relation to the proposed design:
    • The alignment of the proposed crossover ensures that vehicles associated with lot 4 do not enter the
         property boundary of 22 Ghostgum Court. The new pavement (crossover extension) is entirely
         within the verge;
    • All vehicles associated with Lot 4 are able to enter and exit the site in a forward gear. As requested
         by Council, swept path analysis has been carried out and included as Attachment B.;
    • Given Lot 4 will contain a single dwelling, site generated traffic will be negligible and will not
         adversely impact on the ability of the resident at 22 Ghostgum Court to continue to access and
         egress their property;
    • The location of the crossover is at the end of a cul-de-sac where traffic volumes are negligible; and
    • Sightlines at the proposed crossover are unrestricted in all directions.
The non-standard geometry of the existing crossover provides an opportunity, not a constraint for the
proposed lot 4. The proposed geometric design is a sensible and clever use of the surplus width available. In
my capacity as a Registered Professional Engineer of Queensland, the proposed crossover for Lot 4 is
considered both safe and functional.
