A major success factor for the project is represented by an effective private-public partnership. In 1992, the British Government launched the Private Finance Initiative, a public-private partnership programme, as a way of providing higher quality and more cost effective public services (Marsh, K, Philpot, M, Payne, D, Russell, D - Broadland; a current model of future delivery? 2010.). Through the Broadland contract the Environment Agency has effectively delegated certain flood risk management functions to a private company, Broadland Environmental Services Ltd. This Private Finance Initiative shell company is used to deliver the contract, comprising stakes of 90% BAM Nuttall Ltd and 10% Halcrow Group Ltd (now CH2M HILL). This Consortium is entrusted with improving and maintaining the Agency’s assets, providing emergency services and acting as a custodian for the environment (Ayling, B, Rowntree, J, and Lancastle, B - Broadland Flood Alleviation Project. Paper presented at Defra Conference, 2002; hereafter Ayling et al., 2002).
A key reason for the success of the Broadland Project has been the equality maintained between the two partner organisations (one public and another one private) particularly given the unequal split in financial risk. The choice of partners and the recognition that each requires the other one’s strengths has been key to building a strong team. The strong interaction between the two company members of the consortium and the UK Environment Agency represented the strength and the main successful factor of this project (Ayling et al., 2002).
Despite all the positive sides of the implementation of this project, a massive flood protection intervention in a large area such as the one under consideration has also negative impacts. The main limitations (some of them just temporary) identified could be listed as follow:
- Temporary disturbance to residential property;
- Possible changes in land use from the construction of the flood defence;
- Possible impacts on undefended communities by altering the flooding pattern;
- Temporary visual effects of works during construction;
- Temporary loss of vegetated areas;
- Visual impacts of new, large soke dykes;
- Temporary disturbance of flora and fauna.
