In the case of a proposed zone change, including prezoning, further notice shall be given by first-class mail to any person who has filed a written request therefor with the Planning Commission. Such a request may be submitted at any time during the calendar year and shall apply for the balance of each calendar year. The City may, pursuant to a resolution of the Council, impose a reasonable fee on persons requesting such notice for the purpose of recovering the cost of such mailings. Further notice of the hearing shall be given by mail including businesses, corporations or other public or private entities shown on the last equalized assessment roll as owning real property within 300 feet of the property which is the subject of the proposed change of districting. In the event that the proposed zoning district which has been requested by a person other than the property owner, as such property owner is shown on the last equalized assessment roll, notice shall also be given by mail to such owner.
