Financial Viability Appraisal in Planning Decisions: Theory and Practice

Local planning authorities set these policies on an area-wide basis but ultimately development proposals require consent on a site-by site basis. It is at this site-specific level that issues of viability are hotly contested. This research examined case documents, proofs of evidence and decisions from a sample of planning disputes in order to address major issues within development viability, the application of the models and the distribution of the development gain between the developer, landowner and community. The results have specific application to viability assessment in England and should impact on future policy and practice guidance in this field. They also have relevance to other countries that incorporate assessments of economic viability in their planning systems.
