How to Delegate and Comment to City Council
Delegating is making a presentation to City Council or a Committee. It is your chance as a citizen to make your opinions known on any matter that comes before council. Currently all committees are “committees of the whole” which means they consist of all counselors, so there is no real difference between presenting to council or a committee.
Commenting is submitting a written comment which will be included in the agenda for the meeting and distributed to all counselors. If you submit a PDF file your formatting will be preserved and is more likely to stand out rather that plain text.
You can submit a comment and delegate for the same meeting You can also email your comment to counselors ahead of time.
How do I register as a delegate or submit written comments?
Committee of the Whole and Council meeting agendas are generally published on the Thursday two weeks preceding the meeting. If the topic is scheduled to appear on an agenda, you may register and provide written materials/presentations by the Tuesday two weeks prior to the Committee of the Whole or Council meeting in order to be included on the published agenda. Individuals can also delegate on an item included on an agenda if the registration is received by the final deadline – 10 a.m. on the Friday prior to the meeting (Thursdays at 10:00 a.m. if City Hall is closed on the Friday for a holiday observance).
Written comments and presentations (including PowerPoint presentations) received by the final deadline at 10 a.m. the Friday prior to the meeting (Thursdays at 10:00 a.m. if City Hall is closed on the Friday for a holiday observance) hall be included on the consolidated agenda and distributed to Committee and Council members.
