The Zoning Hearing Board of Cheltenham Township shall increase by adding one, two or three residents to serve as alternate members of the Board. The Township Zoning Hearing Board will continue to have three members to hear applications, and, when required, a member will be replaced by an alternate. The Township Zoning Hearing Board Chairman will determine if an alternate is needed and, if there is more than one alternate, who will serve at any hearing. An alternate who participates in a Zoning (Board) hearing will remain on that panel until that particular case is concluded. No more than two alternates will serve on a panel at any time.
