The city council may from time-to-time amend, supplement, or change by ordinance the boundaries of the zoning districts or the regulations herein established.

The planning and zoning commission or the city council may, on its own motion, institute proposals to amend, or change a zoning district boundary or zoning regulation in the public interest.

The owner of any real property, or his agent, upon proof of such ownership, may file an application to change a zoning classification on such property.

The property owner, lessee, developer, or option holder of any property may petition the city council for an amendment to the text of this Ordinance which affects such property.

A person making application for an amendment to the zoning ordinance shall pay a fee in an amount determined, and as from time-to-time approved by the city council.

Before taking action on any proposed amendment, supplement, or change, the city council shall submit the same to the planning and zoning commission for its recommendation and report. The planning and zoning commission shall hold a public hearing on any application for any amendment, supplement, or change to the Zoning Ordinance prior to making its recommendation and report to the city council. Written notice of all public hearings before the planning and zoning commission on a proposed amendment, supplement, or change to a district boundary shall be sent to all owners of real property lying within 200 feet of the property for which the change is requested. Such notice shall be given not less than 10 days before the date set for hearing by depositing a notice properly addressed and postage paid in the United States Mail to such property owners as their ownership appears on the last approved city tax roll.

The erection or continued maintenance of the sign shall not be deemed a condition precedent to the holding of the public hearing, the adoption of any proposed zoning change, or any other official action concerning such amendment.
