It is intended that planned unit development districts be established along major corridors and in growth areas. Applicants' planned unit development master plans should demonstrate a unified development with an interconnected system of internal roads, sidewalks, and paths, as well as management of access points along existing roads in order to maximize safety and the efficiency of existing roads. Pavement widths of internal and external roads shall minimize paving requirements while accommodating projected traffic generated from the district. Planned unit developments allow for a higher density of development for a more efficient use of the designated growth areas and for more effective preservation of the open areas of the Town. Other benefits of a planned unit development include less infrastructure costs, more efficient provision of public safety services, less environmental impact and, through the provision of affordable housing, the achievement of significant economic and social integration.
