Site-Specific Viability Assessment Format and Content

Viability assessments must be based on open book residual valuation, include all relevant costs, clarify assessment date, include sensitivity testing, be proportionate and transparent, exclude actual land prices as justification, and incorporate review mechanisms.

A site-specific viability assessment undertaken to support a planning application should be based on the following factors: • Assessments should be supported by appropriate available evidence, informed by engagement with developers, landowners, infrastructure and affordable housing providers. They should: o Provide a full open book appraisal, based on the residual valuation model; o Include all relevant costs (for example site holding costs, third party interests etc.); o Clarify the date on which the assessment was undertaken; and o Include sensitivity testing. • Assessments should be proportionate, simple and transparent, providing an Executive Summary for publication; • The actual price paid for land will not normally be a relevant justification for failing to accord with the relevant policies in the LDP; and • Review mechanisms should be incorporated to strengthen the Council's ability to seek compliance with relevant policies over the lifetime of proposed developments, and to optimise public benefits through economic cycles.
