Required interval for hearings on applications and appeals after
denial. Whenever the Board, after hearing all the evidence presented
upon an application or appeal under the provisions of this chapter,
denies the same, the Zoning Board of Appeals shall refuse to hold
further hearings on the said or substantially similar application
or appeal by the same applicant, his successor, or assign for a period
of one year, except and unless the Zoning Board of Appeals shall find
and determine from the information supplied by the request for a rehearing,
that changed conditions have occurred relating to the promotion of
the public health, safety, convenience, comfort, prosperity, and general
welfare, and that a reconsideration is justified. Such rehearing would
be allowable only upon a motion initiated by a member of the Zoning
Board of Appeals and adopted by the unanimous vote of the members
present, but not less than a majority of all members.
