Notification requirements. The Board shall give public notice of all matters to be heard at any given meeting and shall give, by certified first-class mail, written notice to the owner, appellant, Council, Planning Commission, to the governing body of any municipality located within 500 feet of the property at issue, and to all other interested parties who have registered their names and addresses with the Board, and at the sole discretion of the Zoning Officer, to the occupant of every lot on the same street within 200 feet of the lot in question and of every lot not on the same street within 100 feet of such lot. The notices herein required shall state the location of the building or lot, the general nature of the question involved and the time and place of the hearing. In addition to the notices provided herein, notice of said hearing shall be conspicuously posted on the affected tract of land, building or sign. Failure to remit written notice shall not be a fatal procedural defect so long as an appeal is properly advertised.
