Sign in on the list of people who want to speak. When your name is called, speak at the lectern. State and spell your name and give your address. If you are reading comments, make copies available for council members and the city clerk. Give them to the clerk.
Some cities limit speakers to three minutes.
Make your comments and remember that you are being recorded. Don't speak from your seat or yell out comments. If you speak again later, come to the lectern and restate your name. Don't be surprised if you don't get an immediate response or answer to comments or questions you raise. Usually, council members will just listen.
