The statutory component parts of the local development framework. Core strategies, area action plans and site-specific allocations are all DPDs.
The procedure for their creation is set out in Planning Policy Statement 12.
In brief, issues and options are drawn up and informally consulted on leading to a set of preferred options. These are formally consulted on, finalised for submission to the secretary of state then tested for soundness at an examination in public. A sustainability appraisal, which includes a strategic environmental assessment, should run in tandem with this process and is likewise examined. The DPD is then subject to implementation and monitoring.
The Planning Inspectorate (PINS) has produced a plain english guide for the general public on the examination of DPDs.
