The Master Plan for Cinnaminson Township adopted February 22, 1983, proposed the designation of certain sites for senior citizen townhouses. This recommendation was based on a study of census data indicating a marked trend toward a greater proportion of elderly in the age bracket of 55 to 64. An intent and purpose of the Municipal Land Use Law is to encourage senior citizen community housing construction, pursuant to N.J.S.A. 40:55D-21.
