The purposes for the creation of the Active Adult Community Overlay District and the development standards and other requirements are:
A. 
To recognize the need for the expansion of housing opportunities and particularly the growing housing needs of older members of the population.
B. 
To recognize that less community facilities and services impacts of elder communities and their lower average household size can justify a higher density of development.
C. 
To encourage the development of planned communities that offer a mix of housing and nonresidential commercial retail and service uses, designed to serve the planned community, in order to reduce the need to travel off-site.
D. 
To encourage innovative residential community site design that meets the demand for varying dwelling unit types and provides for the recreational and open space needs of the community's residents.
E. 
To encourage more flexible site design standards that will provide for the protection of the Township's environmental resources and the preservation of its character.
F. 
To encourage the most efficient use of Township's land and infrastructure resources.
