Table 6 and Table 7 collectively indicate that the development’s parking supply will be less
than the acceptable outcome with a shortfall of 306 spaces for Lot 3 and 3 spaces for Lot 7.
As such, a parking demand assessment, through an evidence-based approach, has been
undertaken, whereby the acceptable outcome parking rates have been adopted, in addition to
considering the different peak demand times of the proposed component uses making up the
proposed development. As an example, restaurant tenancies are typically busier in the
evening while traditional retail tenancies are either closed or trading at a lower intensity. This
approach accounts for the variabilities in demand across a temporal profile for each tenancy
and ensures parking provision is not delivered in surplus to the development’s needs. The
individual parking rates nominated as acceptable outcomes in the Planning Scheme do not
consider the variability in demand across an integrated mixed use development such as the
Noosa Village Mixed Use Development.

5.2        Parking Demand Assessment
5.2.1      Methodology
To further assess whether the proposed parking supply would be sufficient to accommodate
the demands generated by the new development, SLR has prepared a parking demand
assessment for consideration by Council. The methodology adopted for the assessment is
outlined as follows:
       Step 1 – Identify Council Acceptable Outcome rates: As discussed in the previous
        section.
       Step 2 – Collect Google analytical data/profiles: Google analytical data was
        collected for existing comparable uses that correspond to each of the proposed
        tenancy types. This step informed an understanding of the likely trading intensity of
        tenancy types across the day to establish a representative carpark utilisation profile
        throughout the hours of operation.
       Step 3 – Forecast parking demands for individual tenancy types: Estimate the
        parking demands on a Thursday and Saturday of the proposed development by
        extrapolating Google analytical data to establish a typical parking demand profile. For
        example, the proposed cinema tenancy requires 243 parking spaces in accordance
        with Council’s DPC. The carpark utilisation rate generated by the profile indicates that
        only 11% of these spaces will be required to cater for the demands between 9-10am
        on a typical Thursday morning. As a result, parking demands during this period for the
        proposed cinema are approximately 27 spaces.
       Step 4 – Combine parking demands from all proposed land uses: Given the nature
        of the assessment, a 15% ‘factor of safety’ was applied to the parking demand profiles
        to ensure conservativeness. These parking demand profiles were then combined to
        obtain the peak parking demands of the proposed development.
Importantly, the above methodology was not applied to the proposed residential land use. SLR
assumed that the residential land use generates a constant demand of 121 spaces (across
both lot’s 3 and 7) and these parking spaces are fully occupied at all times. These car parking
spaces will be reserved for resident and short-term accommodation parking.

5.2.2      Existing Representative Uses and Trading Profiles
For undertaking Step 2 as described in Section 5.2.1, SLR sourced representative land use
trading profiles from Google analytical data for a typical Thursday and Saturday. Table 8
provides details of the selected existing uses sourced for informing the parking demand
assessment.
