Upon the filing of an application for variance, the zoning administrator shall set the matter for hearing. A notice of hearing shall be mailed at least ten calendar days prior to said hearing to all property owners, any part of whose property lies within a radius of three hundred feet of the applicant’s property, using for this purpose the names of such owners as shown on the last equalized assessment roll, or alternatively, from such other records of the assessor or the tax collector as contain more recent addresses. In addition, if warranted in the determination of the community development director, notice shall be provided by conspicuously posting the subject property for at least ten days prior to the hearing. Failure to receive the notice by this section shall not invalidate the action of the zoning administrator. (Amended during the March 2009 supplement.)
