Purpose. The purpose of this section is to provide a method of developing single-family detached dwellings which will preserve desirable open spaces, conservation areas, floodplains, recreation and park area and lands for other public purposes by permitting the reduction of lot sizes and implementation of other regulations contained in this chapter without increasing the number of total lots to be developed. Cluster development is intended to encourage the retention of the borough's historic character, enhance the borough's charm, promote a sense of place and community through good design, and assist in the implementation of the borough's open space and recreation goals. The cluster development technique is also intended to allow residential developments to be constructed at a lower cost per dwelling unit for streets, utilities and other site improvements while creating value for the residents and providing a desirable visual environment through designs that respond to the particular site.
