Any notice required by law to be published by any regional board, commission, department or authority created by or pursuant to statute; any county, city, school district, special district, any joint district, or other political subdivision of the state of Idaho may be published by mailing such notice by first class mail, postage prepaid, to the residents of such jurisdiction; provided, however, that publication by mail as provided for herein, shall constitute legal notice only if the cost of mailing, including preparation, materials and postage, is less than the cost of other publication required by law.
