"Planned residential development (PRD)" means a design technique or development type which allows a land area to be planned and developed as a single entity containing one or more residential clusters or complexes which can include a wide range of compatible housing types. Appropriate small scale commercial, public or quasi-public uses may be included if such uses are primarily for the benefit of the residential development and the surrounding community. A residential density bonus is allowed in exchange for dedication of a minimum amount of passive and active open space for the use and enjoyment of the development’s residents.
