My full name is Duncan Barry Tindall. I hold the position of Technical Director in the Transport Planning and Traffic Engineering team at GHD New Zealand Limited (GHD). 2. I have been assisted in my assessment by Will Bull, Angelia (Zhixuan) Cao and Sharath Kotha who have completed intersection modelling, and assessment under my supervision. I have also relied on the work of Flow Transportation Specialists led by Ian Clark who have undertaken transport network modelling to support my assessment. 1.1 Qualifications and experience 3. I hold the academic qualifications of Masters of Science in Traffic and Transport from the University of London (Centre for Transport Studies) and a Masters of Engineering in Civil Engineering, also from University of London (Imperial College). I am a Member of Engineering New Zealand. 4. I have worked in the field of transport for 23 years and have been working and living in New Zealand since 2010. During this period I have worked on a range of transportation planning projects, development planning and development control across New Zealand. Prior to joining GHD in 2019 I was an Associate with Beca New Zealand and an Associate Director with AECOM New Zealand limited. 5. Prior to undertaking my assessment, I visited the site on several occasions. I was also present throughout two public open days that were held in support of the scheme, during which time I discussed a range of transport and traffic related issues with the community. 1.2 Code of Conduct 6. I confirm that I have read the Code of Conduct for expert witnesses contained in the Environment Court Practice Note 2014. This assessment has been prepared in compliance with that Code, as if it were evidence being given in Environment Court proceedings. In particular, unless I state otherwise, this assessment is within my area of expertise and I have not omitted to consider material facts known to me that might alter or detract from the opinions I express. 1.3 Background 7. RiverLink is a partnership project between Greater Wellington Regional Council (GW), Hutt City Council (HCC) and Waka Kotahi NZ Transport Agency (Waka Kotahi), together with Mana Whenua partners Ngāti Toa Rangatira (Ngāti Toa) and Taranaki Whānui ki Te Upoko o Te Ika (Taranaki Whānui), collectively known as the Project Partners. RiverLink has arisen to address flood protection issues, transport resilience, accessibility, efficiency and safety issues at the Melling intersection on State Highway 2 (SH2) and urban renewal and regeneration of Lower Hutt central city. RiverLink seeks to resolve these issues and provide an integrated design solution that achieves the best outcome for Lower Hutt. 8. RiverLink is the brand adopted by the Project Partners for the collective and integrated approach to a series of projects within a 3 kilometre section of the Te Awa Kairangi/Hutt River (the River) between Kennedy Good Bridge and Ewen Bridge and the immediate urban environs on either side, including the edge of Lower Hutt as it meets the central city. 1 1.4 The RiverLink Project 9. RiverLink’s three separate but interdependent projects include: Flood Protection (GW)
