Furthermore, planned unit developments are designed to forward both the aesthetic and economic development objectives of the Village by controlling the site design and the appearance, density or intensity of development in terms of more flexible requirements for land uses, density, intensity, bulk, landscaping, and parking requirements. In exchange for such flexibility, the planned unit development shall provide a much higher level of site design, architectural control and other aspects of aesthetic and functional excellence than normally required for other developments.
