A development plan sets out the policies and proposals for the development, conservation and use of land and buildings in a particular local planning authority area. The development plan is the most important consideration for local planning authorities when they decide on a planning application. The development plan generally includes Development Plan Documents (DPDs) that are part of a local planning authority’s Local Plan. This includes waste and minerals documents prepared by county councils. The Localism Act 2011 made two key changes to the development plan. First, the Regional Strategies that have been part of it since 2004 will be abolished. Secondly, Neighbourhood Plans that have been prepared covering any part of the local planning authority area will become part of the development plan if they’ve received enough support in a referendum.
