Regular reviews of conservation areas are known as Conservation Area Appraisals. The public is consulted, to ensure that the appraisals reflect community aspirations and not simply those of the planning authority. Once published conservation area appraisals provide the local planning authority with the basis for policies which are designed to preserve or enhance all of the aspects of character and appearance that define an area's special interest.
Further controls, called Article 4 Directions, apply in some conservation areas (those in the former Waveney district).
