The focus of our work was on the development of a strategic and economic case for investment in public realm and infrastructure improvements in the Lansdowne business district of Bournemouth .
To develop the strategic case for the investments we conducted a documentary review to understand the context for the development as well as looking at case studies elsewhere and preparing a logic chain. For the economic case we considered five options shortlisted by Bournemouth Borough Council. For each shortlisted option we calculated the gross and net additional benefits of the developments that could be brought forward as a result of the intervention. This allowed us to calculate the benefit-to-cost ratio and the net present value of the public sector investment in the area. We conducted sensitivity testing on the benefits from the schemes as well as taking into account optimism bias.
The analysis allowed Bournemouth Borough Council to understand the costs and benefits associated with each of their shortlisted options. It also provided a basis to prepare a full Green Book compliant business case for their chosen option in the future.
