How are viability issues identified, and what can be done about them?
At a very simple level a site specific viability assessment looks at the values and costs of a particular proposal.
By deducting the costs from the values you get an outcome, the 'residual', which in our suggested approach would be how much is left to contribute to S106 contributions.
Therefore, by definition, reducing costs, and or increasing values, will improve the viability of a particular scheme.
One of the benefits of using an RLV, is that this method of calculation offers a simple way to model the financial outcomes of different schemes. For example, by trying out different numbers, and/or a different mix of size and types of housing it will be possible to see if viability can be improved.
