If action by the Board of Supervisors is a tie vote on any matter arising out of titles 20, 21, and 22 of this code, whether or not the matter is before the Board on appeal, the Board may, following the tie vote and in advance of adjournment of the meeting during which the tie vote occurred, continue the matter for further consideration and determination to a time and date certain not later than thirty calendar days following the date on which the tie vote occurred. If the matter is not continued for further consideration and determination in the manner specified above, such tie vote shall be deemed to constitute a denial or disapproval effective on the date the tie vote occurs of the matter for which application is made (and in the case of an appeal, denial of the action requested by the application, as distinguished from denial of the appeal), and such action shall be deemed to be final and not subject to reconsideration pursuant to the application upon which the vote was taken. If during the meeting to which consideration and determination is continued pursuant to this section another tie vote occurs, the application shall, effective on the date of such continued meeting, be deemed denied in the manner prescribed above and the action shall be deemed to be final in the manner prescribed above. During the meeting to which consideration and determination is continued pursuant to this section, no new or additional evidence shall be received or considered unless any public hearing required by law has been reopened and any notice thereof required by law has been given.
