(LDS) – which outline the work the LDDs/SPDs they intend to produce over a three-year period, and Statements of Community Involvement (SCI), which outline how the Council will involve the local community. All LDDs and SPDs also have to be accompanied by a Sustainability Appraisal (SA) and a Strategic Environmental Assessment (SEA). The SEA is a requirement under European Union laws. Planning Policy Guidance Notes are also being gradually replaced by Planning Policy Statements. Minor variations were allowed to planning permissions, recognising that information provided for planning permission does not provide enough detail for actual construction. Working drawings are required first, and architects often make small changes to accommodate a building's technical requirements. Also, plans might change on site to overcome unforeseen problems. Legality of minor amendments was challenged in 2006, and central government advice to many local authorities was that any variation to a planning permission should require planning approval. The Localism Act 2011 introduced wide-ranging changes to the planning system in England. The bill introduced legal provision under which local communities (led by parish councils or neighbourhood forums) could develop neighbourhood plans. Similar to development management documents produced by the local authority, neighbourhood plans have statutory weight, so that they are considered in the determination of planning applications. Online access Historically, planning applications were submitted in paper form to designated Council offices and displayed for a statutory period at public libraries or offices. In December 1995, the London Borough of Wandsworth created a website that published electronic images of planning application documents. This technology greatly improved access to application-related documents for all participants in the planning process. Within ten years, most planning authorities within the UK followed suit. Other access methods now include routing inquiries through a centrally-hosted public or privately hosted website, such as UKPlanning or the national Planning Portal. Appeals An applicant may appeal against a refusal of planning permission. A neighbour who objects to an application has no right of appeal, but may appeal to the local authority ombudsman if they can make a case of maladministration by the local authority. In such a case the ombudsman has no powers to enforce a retraction of the permission, but it may sanction the local authority. Appeals can be made: In England, to the Secretary of State for Communities and Local Government. In Northern Ireland, to the Planning Appeals Commission. In Scotland, to the Scottish Government; Directorate
