A heritage impact assessment

Published on 15 November 2018 - Updated 17 December 2021

The purpose of the assessment is to assess the extent of the changes that the project will bring about and objectively demonstrate whether the project is compatible with the aim to maintain the OUV. It must answer the following questions: Which of the component parts of the Property's OUV are likely to be affected? What changes will the project bring about? Can adverse effects be avoided, reduced, rehabilitated or compensated, and how?

How to ?

  • Call on a specialist consultancy firm to implement specifications whose contents follow the method recommended by ICOMOS;
  • Conduct consultations with the project stakeholders as far in advance as possible and, in particular, have the latter approve the different stages, not least the stage defining the project scope, the involvement of each party in implementing this assessment and the skills of the experts sought;
  • Draw up an assessment of the OUV that is as exhaustive as possible, by including historical and geographic research, site visits, significant sequences and viewpoints, inter-visibility and terrain modelling. All types of research techniques, from scientific analysis to collection of oral histories and virtual 3D scale models, may be valid and useful;
  • Collaboration between the local government departments, the departments in charge (DREAL, DRAC) and Mission Val de Loire World Heritage is preferable to facilitate performance of the HIA.
