Planned unit development

From Wikipedia, the free encyclopedia

A planned unit development (PUD) is a type of flexible, non-Euclidean zoning device that redefines the land uses allowed within a stated land area. PUDs consist of unitary site plans that promote the creation of open spaces, mixed-use housing and land uses, environmental preservation and sustainability, and development flexibility.[1] Areas rezoned as PUDs include building developments, designed groupings of both varied and compatible land uses—such as housing, recreation, commercial centers, and industrial parks—within one contained development or subdivision.[2] Developed areas vary in size and by zoned uses, such as industrial, commercial, and residential.[3]:2 Other types of similar zoning devices include floating zones, overlay zones, special district zoning, performance-based codes, and transferable development rights.[4]:2
