4.0      TRAFFIC OPERATIONS

4.1      DEVELOPMENT PROFILE

         4.1.1        Staging
         For the purpose of quantifying the traffic impact of the proposed development, the following
         development staging has been adopted:

         —        Traffic Counts:                              2026
         —        Development Application:                     2028
         —        Construction and Occupation:                 2028
         —        10-Year Design Horizon:                      2038

         4.1.2        Assessment Scenarios
         This has led to the following assessment scenarios being considered:

         —        opening year (2028) pre-development
         —        opening year (2028) post-development
         —        future year (2038) pre-development
         —        future year (2038) post-development

         4.1.3        Background Traffic Growth
         The background traffic growth for the impact assessment area has been estimated based on the
         10-year growth in Average Annual Daily Traffic (AADT) as reported by TMR for Eumundi Noosa
         Road (identification number 20363). A simple growth has been used, as required by Section 4
         of TMR’s GTIA. This calculation is summarised in Table 4.1.

         Table 4.1:            BACKGROUND TRAFFIC GROWTH
           SITE                                         2014 VPD               2024 VPD                  % INCREASE

           20363 Eumundi Noosa Road                       11,700                 13,920            19.0% over last 10 years
           Forecast (= 12 / 10 x 19.0%)                                                            25.3% over next 12 years

         Accordingly, background traffic between 2026 (the year of the counts) and 2038 (year of opening
         plus ten years) is expected to grow by 25.3%.

4.2      TRAFFIC GENERATION
         The traffic generation for the site has been determined as follows:

         —        weighbridge data was used to determine a trip generation rate for:

                  —       green waste:                         1.47 vehicles per tonne
                  —       mulch / compost sales:               0.21 vehicles per tonne

         —        of the 30,000 tonnes of green waste expected post development, approximately 5,220
                  tonnes would be received in an equivalent month to the weighbridge data (ie 17.4%)
         —        once processed, this would result in approximately 3,130 tonnes of compost (ie 60% of
                  green waste mass)
