A. The purpose of the planned unit development is to allow diversification in the relationship of various uses and structures to their sites and to permit more flexibility in the design of a development. A planned unit development is a rezoning and the planned unit development constitutes an overlay zone. The application of planned unit concepts is intended to encourage good neighborhood, housing or area design, public health, safety and general welfare, and at the same time, securing the advantages of large scale site planning for residential or commercial developments, or combinations thereof.
B. Planned unit development may be:
1. The development of compatible land uses arranged in such a way as to provide desirable living environments that may include private and common open spaces for recreation, circulation and/or aesthetic uses;
2. The conservation or development of desirable amenities not otherwise possible by typical development standards;
3. Creation of areas for multiple use that are of benefit to the neighborhood or environment of the area. (1998 Code § 17.56.020)
