What does Development Plan Documents (DPDs) mean in a planning context?

Development Plan Documents are prepared by local planning authorities and outline the key development goals of the local development framework. Development Plan Documents include the core strategy and, where needed, area action plans. There will also be an adopted proposals map which illustrates the spatial extent of policies that must be prepared and maintained to accompany all DPDs. All DPDs must be subject to rigorous procedures of community involvement, consultation and independent examination, and adopted after receipt of the inspector’s binding report. Once adopted, development control decisions must be made in accordance with them unless material considerations indicate otherwise. DPDs form an essential part of the Local Development Framework.
