The Town Council may impose, upon recommendation of the Planning Commission, such conditions relating to the use for which a permit is granted as it may deem necessary in the public interest, including limiting the duration of a permit, and may require a guarantee or bond to ensure that the conditions imposed are being and will continue to be complied with. No special use permit may be granted except after notice and hearing as provided by § 15.2-2204 of the Code of Virginia, as amended. However, when giving any required notice to the owners, their agents or the occupants of abutting property and property immediately across the street or road from the property affected, the Town may give such notice by first-class mail rather than by registered or certified mail.
