4.3 Estimated Peak Parking Demands

TTM has compiled parking demand survey data from TTM, and other consultant, surveys of existing
Neighbourhood Shopping Centre developments in south-east Queensland that included either a
Woolworths, Coles or Supa IGA supermarket with ancillary uses such as specialty retail, medical centre,
office and restaurant/café uses. Table 3 below presents the results of the peak parking demand surveys for
the fourteen sites.

The 85th percentile peak parking demand rate of all survey data is determined to be 4.56 cars / 100 m2 GFA.
Parking supply requirements for any land use is typically based on the 85th percentile parking demand rate
derived from parking demand surveys. Therefore, application of the above-mentioned rate to the proposed
development is an appropriate means of determining an adequate level of parking supply that would
accommodate the typical peak parking demands of the development.

The proposed development has an overall retail GFA of 4,870 m2 which is typical of the surveyed sites. Based
on the surveyed 85th percentile rate the estimated peak parking demand of the proposed development is
223 cars. To account for seasonal variations in retail trade a factor of 110% should be applied to determine
the required parking supply i.e. the minimum parking supply required for the development is 246 spaces.
