[Added 11-3-2005 by Ord. No. 2005-750]
The intent of the Township in permitting development pursuant to this article is as follows:
A. 
To provide for residential developments that meet the growing needs of older persons, including the need for quality housing, fellowship, open space and recreational facilities.
B. 
To encourage innovations in residential development so that the growing demand for housing may be met by a greater variety in type, design and layout of dwellings, while conserving open space within such a development.
C. 
To recognize that developments housing older persons typically generate lower average rates of vehicular traffic, water usage and sewer usage than other types of residential developments, and have less impact upon the public school system, and a lower average number of residents per dwelling unit. Therefore, a higher density is justified for this type of development than other types of residential uses.
D. 
To encourage flexibility in site planning which will respect and conserve natural resources, such as streams, ponds, floodplains, wooded areas, steep slopes, and other areas of significant beauty or importance to the environment.
E. 
To encourage a sense of community among residents of a complex for older persons through indoor and outdoor facilities for social interaction.
F. 
To provide for patterns of development around the perimeter of a tract that are compatible with neighboring development while allowing greater flexibility within the interior of the tract.

Adjacent units shall have a horizontal offset of at least two feet.
(2) 
Siding materials. The exterior building elevations shall consist of at least 50% face brick veneer or thin set stone. There should be sufficient variety to create an interesting streetscape.

(4) 
Roofing materials. The roofing materials shall be either architectural shingles or metal roof in a suitable and interesting color.
K.

Recreation and open-space areas and facilities shall be located in close proximity to all residents of the complex.
(2) 
Recreation. Recreation areas and facilities shall be provided to meet the anticipated needs of the complex. Recreational areas should be of a size, shape and relief that is conducive to that group's active and passive recreational needs.
