Stantec // Oceana Gold NZ Ltd // Waihi North Project Transportation Assessment 35 Figure 37: Kenny Street Access PM Peak 2032 Sensitivity Analysis (Flow rate) 7.5 Aggregate Supply At this stage OGNZL does not anticipate the need to import aggregate for use as CAF as authorised by previous consents but does anticipate a nominal requirement for the use of aggregate for civils work. While the source of any aggregate is yet to be finalised, it is noted that the closest supplier is the Waitawheta Quarry, which would likely result in trucks making a left turn out of Crean Road and a right turn into Baxter Road (and the opposite movement in the reverse direction). The upgraded SH2 intersections as completed by Waka Kotahi in 2019 has resulted in very short queuing space between the back-to-back right turn bays which would be challenging for a truck to turn across SH2 in opposite directions at the same time . While the likelihood of two trucks meeting at the same time is expected to be infrequent , should that occur, then any competent driver would observe the opposing truck and wait for the way to be clear. This can be managed as part of any traffic management plan. A condition of consent for Project Martha also requires a Traffic Management Plan (TMP) to be prepared for the cartage of aggregate. The TMP enables the supplier of aggregate and route for cartage to be firstly confirmed and further assessment of that route should it be deemed appropriate in consultation with the relevant road controlling authority. In the event that OGNZL does resolve to import aggregate from the Waitawheta Quarry , for any reason, utilising the Crean Road / Baxter Road route, then the TMP is recommended as above to identify measures and protocols to mitigate the possible conflict of opposing flows or other traffic occupying the right turn bays. It is therefore appropriate to carry forward similar consent conditions relating to aggregate mo vements via long trucks between Baxter Road and Crean Road as outlined for Project Martha in Section 4. It is recommended that conditions are included to address the following matters: • Prior to the haulage of large volumes of aggregate using Baxter Road , an annual programme for inspection, recording and maintenance of Baxter Road pavement condition, and bridge condition shall be undertaken; and the road is to be returned to at least its standard / condition prior to the commencement of the aggregate / ba ckfill haulage activity on completion. • The consent holder shall submit a Traffic Management Plan for the haulage of large volumes of aggregate if the aggregate haul route includes the use of Crean Road and Baxter Road together, to the Hauraki District Council for certification at least 30 working days prior to the haulage of aggregate first occurring. 7.6 Parking The expected parking demands associated with the Project have been developed from the proposed travel arrangements described at Section 3. As the parking demands rely on this method of transport it is recommended that suitable conditions of consent are developed to ensure the parking demands are catered for on -site with consideration to the peak operational workforce demands, the type of transport provided by the employer and management by contractors themselves.
