                                                              Proposed Mixed Use Development, 30-32 Doonella Road, Tewantin
                                                                                  Parking & Traffic Impact Assessment Report




4             Proposed Development
4.1           Proposed development
A total of 10 x two-bedroom residential apartments are proposed at the rear of the development across the
ground and first floor. A total of 768 square metres of Commercial spaces are proposed on the ground floor
at the front of the site.
A basement car park is proposed across most of the site with vehicular access to and from Doonella Street.
The proposed development plans that are the subject of this Traffic Impact Assessment are appended to this
report.

4.2           Traffic Generation
An indication of the traffic generation potential of the development proposal is provided by reference to the
Roads & Maritime Services Guide to Traffic Generating Developments, Section 3 – Land use Traffic
Generation (October 2002).
The RMS Guidelines are based on extensive surveys of a wide range of land uses and nominate the
following traffic generation rates which are applicable to the development proposal:
Application of the above traffic generation rates to the various components outlined in the development
proposal yields a traffic generation potential of 20 peak hour vehicle trips as set out in the table below:

 Land Use                     Generation Rate                GFA/No. Units                Total Trips

                              trips = 2 per 100 m2 gross               728 m2                        15
                                       floor area.
 Total Trips Generated                                                                               20



The projected future level of traffic activity should however, be offset or discounted by the level of traffic
activity which could reasonably be expected to have been generated by the previous uses of the site, in
order to determine the nett increase in the traffic generation potential of the site as a consequence of the
development proposal.
Application of the “previous” traffic generation rate nominated in accordance with the RMS Guidelines of
Traffic Generating Developments for the existing land uses for both sites is provided below:
