This report prepared by Peter Brett Associates LLP on behalf of the South East Lincolnshire Joint Strategic Planning Committee (representing Boston Borough, South Holland District and Lincolnshire County Councils) sets out the viability assessment of the South East Lincolnshire Local Plan 2011-2036, Draft for Public Consultation - January 2016 (the Draft local Plan). This report also includes the affordable housing assessment and assessment of developer contributions to support the planned growth. 2. The National Planning Policy Framework (NPPF) states that plans should be deliverable and that the sites and scale of development identified in the plan should not be subject to such a scale of obligations or policy burdens that their ability to be developed viably is threatened. Approach to viability assessment 3. A plan level residual value approach to viability was undertaken for residential and commercial development to inform the study findings. The approach takes the difference between the development values and all development costs, and compares the ‘residual land value’ with a threshold land value to determine if the development is viable. 4. The appraisal undertaken uses appropriate available evidence, which has been informed by an assessment of market evidence, viability appraisals and stakeholder consultations. Appendices B and C set out the research that has informed the viability assumptions for this study. 5. An iterative process has been adopted. Work on the viability study commenced during summer 2015 and has been prepared alongside work on the South East Lincolnshire Infrastructure Delivery Plan 2016 (the IDP). The draft viability vtudy report was consulted on by the client team alongside the Draft f Local Plan in January 2016. Further viability evidence was provided by the two local authorities during 2016 - this has
