There's been some question about whether or not the executive session that led to Lutz's ouster was born of a regular meeting, and thus subject to the requirement that 'the presiding officer of a governing body shall publicly announce the purpose for excluding the public from the meeting place' (RCW 42.30.110(2)).

The Internet Archive's snapshots of https://srhd.org/programs-and-services/board-of-health/meetings on

• 2020-04-27,
• 2020-05-25,
• 2020-06-05,
• 2020-07-18 , and
• 2020-09-16

contain references to, respectively, the regular meetings of

• 2020-04-30,
• 2020-05-28,
• 2020-06-25,
• 2020-07-30, and
• 2020-09-24.

(For that matter, the next meeting is currently listed as a regular meeting.)

While no snapshots were taken between 2020-09-25 and 2020-10-28, it seems that, indeed, Thursday's meeting was initially public.
