I had a hard time finding a non-unanimous vote in the record, although abstentions are much more common in recent years. Otherwise it’s like (copying the outcome lines from the start):
Approved 11-0-0, 2024-2-14
Approved 10-0-0, 2024-2-14
Approved 11-0-0, 2024-2-14
Approved; 9-0-1, 2024-2-14
Approved 10-0-0, 2023-12-13
Approved 8-0-2, 2023-12-13
Approved; 8-0-1, 2023-12-13
Approved; 9-0-0, 2023-11-15
Approved 8-0-0, 2023-10-12
Approved 8-0-1, 2023-10-13
Approved 8-0-0, 2023-10-26
Approved 8-0-0, 2023-11-08
....
So, best I can tell, unanimity is still the norm. Then again, there’s rarely any controversy about the things the Board votes on
