Scheme Viability Assessment Framework
A development is considered viable when it provides a suitable return to the developer and sufficient land value to persuade the landowner to sell. The Council uses the Residual Land Value (RLV) method with four key inputs to determine viability.
Scheme viability is a material consideration in the determination of all planning applications where it can be demonstrated that the costs of meeting policy requirements in full may render a scheme economically unviable. In simple terms, a development is viable where, after taking account of all costs, the final scheme will provide a suitable return to the developer and provide a land value sufficient to persuade a landowner to sell the land for the development proposed. If these conditions are not met, a scheme is unlikely to be delivered.
Where this is accepted, the Council will follow the Residual Land Value (RLV) method, which is an equation where a combination of inputs can be used to calculate the missing element. The four key inputs used as part of this method of determining development viability are:
• Benchmark land value
• Construction/development costs,
• Developer return and
• The costs of compliance with other policies.
