Independent Viability Appraisals

The submission of a viability appraisal is required where an application seeks to depart from specified SDNPA policies.  Submitted viability information will be assessed by the SDNPA who will seek the services of an independent assessor to give advice on viability where appropriate.  In order that your viability appraisal can be assessed, you are required to  complete our External Viability Appraisal Agreement form and commit to pay for the independent assessment of viability documentation.
