Executive Summary This report describes the strategic transportation modelling of a comprehensive residential, transport, warehousing and logistics development at Ruakura, initiated by Tainui Group Holdings (TGH) and Chedworth Properties (CP). The modelling has been undertaken in the Waikato Regional Transportation Model (WRTM) in consultation with a forum set up under the Future Proof structure encompassing representation from the development team and Future Proof partners. This report describes model inputs and outputs for scenarios at 2021, 2041 and an ultimate development scenario. Options with and without full completion of the Waikato Expressway have been considered. The modelling has shown that under all scenarios the comprehensively planned transportation network within Ruakura, in combination with other possible improvements on the external network, can facilitate the proposed development. These possible improvements include increases in capacity at major intersections along Ruakura Road and consideration of local area treatments. The modelling has shown how traffic patterns are expected to change when Ruakura is at various stages of development. Within Hamilton City the variations in cross-city movement, based on bridge volumes, are minimal and range from -1% to +4%. The only material changes in traffic volumes occur in the vicinity of Ruakura on links such as the E1, Fifth Avenue and Ruakura Road which are key gateways to the Ruakura area. Traffic volume changes on the State Highway and Waikato District network are similarly minimal except in the vicinity of the site. The model predicts changes on links including State Highway 26 where there is an increase due to a shift away from Holland Road. It is expected that additional capacity at intersections along Ruakura Road and appropriate management of the corridor can minimise this shift. The level of service outputs demonstrate that the internal transportation network proposed for Ruakura can ably support the development and that there are no material changes to level of service elsewhere on the network. The proposed Ruakura interchange operates at a good level of service and facilitates direct and efficient access to the strategic transportation network, particularly for heavy inter-regional vehicle movements. Analysis of overall network performance outputs from the model shows that Ruakura increases the total amount of travel on the network. This is consistent with the approach that has been taken to the modelling where a proportion of the activity is modelled as being entirely new and attracted into the Waikato region because of the inland port. The statistics also show that introducing Ruakura provides improvements in measures such as average operating speed and better emissions performance. A test has been undertaken to assess full development of the structure plan area. This is currently envisaged to be at a year well beyond the 2041 horizon. This test has shown that full development of the area can be supported with a four-lane E1 corridor and some additional capacity on a section of Ruakura Road. The test confirms that the network proposed in Ruakura is appropriate to support full development. The report concludes with recommendations for next steps including further engagement with road controlling authorities and progression to detailed planning and design to ensure the transportation aspirations of all parties are achieved.

Introduction This report has been prepared to summarise the strategic transportation modelling of the proposed Ruakura development initiated by TGH and CP. The modelling has been undertaken using Version 7 WRTM. This model is owned and managed by Local Authority Shared Services (LASS). This modelling has been commissioned through the LASS structure and undertaken by the model operators, Gabites Porter Consultants (Gabites). This report has been prepared for presentation to the Ruakura Transportation Subcommittee (“the subcommittee”). This has been set up as a forum under the Future Proof structure and comprises members from: Hamilton City Council (HCC) New Zealand Transport Agency (NZTA) Waikato Regional Council (WRC) Waikato District Council (WDC) Boffa Miskell TGH Traffic Design Group (TDG) This report has been prepared to provide a summary of the modelling inputs and outputs. Further technical detail and the full modelling outputs are provided in Appendices A to N. 3. Scenarios Modelled Four scenarios have been modelled, two at the year 2021 (with and without Expressway), one at the year 2041 and one at a non-specific ultimate year with full structure plan area development. The first three scenarios have been compared with their relevant base scenario. The scenarios contain land use which aligns with Future Proof submissions. The purpose of the ultimate full structure plan scenario is to assess whether the overall transportation
