Key assumptions for site constraints and existing use value
Where specific site constraints exist (contamination, flood mitigation, heritage assets, archaeology) or sites have unrealistic existing use values, these costs and circumstances should have been factored into land value assessment.
Where there are specific site constraints, e.g. contamination, flood mitigation, access difficulties, protected heritage assets, potential archaeological remains etc. In this case, it would be expected that the costs of dealing with these constraints would have been considered when assessing the value of land; or Where sites have a theoretical existing use value that is unrealistic, for example a long vacant site that might have a value for industrial use in a location with a surplus of such land.
