Attachment 5 - Traffic Impact Assessment Final PTT · 132005.638.06

6.0      CONCLUSIONS AND RECOMMENDATIONS

6.1      CONCLUSIONS
         The proposed development at 561 Eumundi Noosa Road, Doonan has been evaluated in terms
         of the site access, internal intersection arrangements, queuing and likely traffic impact. The main
         points to note are:

         —        access to the development is via an existing all-movements crossover on Eumundi Noosa
                  Road, which forms the minor approach of a priority-controlled T-intersection

         —        currently, green waste is processed into mulch at a yield of approximately 80% by weight

         —        there is approximately 155m of queuing space from the existing weighbridge to the site
                  access

         —        queuing from the weighbridge would extend onto the external road network if the vehicle
                  arrival rate exceeded 100vph

         —        the development proposal is for a compost facility

         —        the yield of compost from green waste is approximately 60% by mass

         —        in addition to the compost facility, the proposal includes a second weighbridge location
                  with separate inbound and outbound bridges

         —        both weighbridges would be access via an internal intersection, located approximately
                  60m east of the site access

         —        approximately 90m on-site queuing space is available from the existing weighbridge and
                  140m from the proposed weighbridge, measured to the internal intersection

         —        queuing from the weighbridges would extend onto the external road network if the vehicle
                  arrival rate exceeded 160vph

         —        the proposed development is expected to generate a total of 30 additional trips during
                  the Tuesday and 28 additional trips during the Sunday peak hours

         —        the Eumundi Noosa Road / Site Access priority-controlled intersection is expected to
                  experience LOS A operations during the Tuesday and Sunday peak hours under 2028
                  and 2038 pre and post-development scenarios

6.2      RECOMMENDATIONS
         Based on the above, it is recommended that:

         —        the internal intersection be modified by:

                  —        aligning the eastern leg with the western leg
                  —        installing give-way line marking on the northern and eastern approaches
                  —        installing white edge line marking to more clearly define the intersection area and
                           access to the waste contractor parking
                  —        install wayfinding signage directing traffic to the on-site facilities

         —        five staff parking spaces be provided

         —        the CHR(s) on Eumundi Noosa Road be upgraded to a CHR
