The PUD District is intended to encourage innovative land planning and site design concepts that promote the most beneficial and creative development of land within the Town and that achieve a high level of environmental sensitivity, energy efficiency, aesthetics, high-quality development and other community goals by:

Allowing greater freedom in selecting the means to provide access, light, open space and design amenities.

(3)

Allowing greater freedom in providing a mix of land uses in the same development, including a mix of housing types, lot sizes, densities and/or supporting commercial uses in residential PUD Districts.

(4)

Promoting quality design and environmentally sensitive development by allowing development to take advantage of special site characteristics, locations and land uses.

(5)

Encouraging quality design and environmentally sensitive development by allowing increases in densities when such increases can be justified by superior design or the provision of additional amenities such as public open space.

(b)

In return for flexibility in site design and development, PUD Districts are expected to include innovative design that preserves critical environmental resources, provide above-average open space and recreational amenities, incorporate creative design in the layout of buildings, open space and circulation, assure compatibility with surrounding land uses and neighborhood character, and provide greater efficiency in the layout and provision of roads, utilities and other infrastructure.
