Determination

The process by which a local planning authority reaches a decision on whether a proposed development requires planning permission.

Development

Development is defined under the 1990 Town and Country Planning Act as "the carrying out of building, engineering, mining or other operation in, on, over or under land, or the making of any material change in the use of any building or other land." Most forms of development require planning permission (see also "permitted development").

Development Control & Development Management

The process whereby a local planning authority receives and considers the merits of a planning application and whether it should be given permission having regard to the development plan and all other material considerations.

Development Limits & Development Boundaries

Development limits identify the area within which development proposals would be acceptable, subject to complying with other policies contained in the Development Plan. They seek to prevent development from gradually extending into the surrounding countryside.

Development Plan

A document setting out the local planning authority's policies and proposals for the development and use of land and buildings in the authority's area. This includes adopted Local Plans, neighbourhood plans and the London Plan, and is defined in section 38 of the Planning and Compulsory Purchase Act 2004. 

(Regional strategies remain part of the development plan until they are abolished by Order using powers taken in the Localism Act. It is the Government’s clear policy intention to revoke the regional strategies outside of London, subject to the outcome of the environmental assessments that are currently being undertaken.)

Development Plan Documents (DPDs)

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.
