Meeting Information

The Commission's regular meetings are held on the 1st and 3rd Tuesdays of the month. Meetings begin at 9:00 a.m. and continue until all business for that day is concluded. The Commission meets in the commission meeting room on the first floor of the courthouse. There is an outside entrance to the commission meeting room on the northeast corner of the courthouse.

If you are interested in addressing the Commission, there is a time reserved for public comments at the beginning of every regularly scheduled meeting. To provide for clarity and consistency, the Commission has adopted guidelines for their public comment period.

Public Comment Guidelines:

Anyone wishing to make a public comment must sign in prior to the comments portion of the meeting.

Each individual will be limited to three minutes to make their comments. Individuals who require interpreters or other special accommodations may be given additional time to speak, at the discretion of the Chair. Individuals may not relinquish their allotted time to anyone else.

Comments must be presented using a civil and professional demeanor. Threatening, profane, vulgar, or abusive language will not be tolerated.

No action may be taken by the public body on any comments during the same meeting in which the comments are made. Comments that are related to a topic that the public body feels may require formal action or further discussion may be placed on a future agenda by that public body at their discretion to allow for proper notice pursuant to the open meetings laws.

Comments related to topics that are on the current agenda must be made during the time for discussion allowed for that agenda item.

The period for public comment is intended for the public body to receive comments. Members of the public body are not required to respond to a comment, answer any questions, or engage in any dialogue with the individual making the comments.
