The collector, into whose possession the warrant comes, as far as practicable, shall call upon all persons, resident within the neighborhood, whose names appear upon the assessment roll, or the occupants of the property assessed, and personally, or by written or printed notices left at his or her usual place of abode or mailed to all persons whose names appear on the assessment roll, inform them of the special assessment, and request payment thereof. This notice shall be given by the collector within 10 days after his receipt of the warrant and shall indicate the date on or before which the assessment may be paid in whole or in part without interest. Under Section 9-2-48 interest on assessments shall begin to run from 60 days after the date of the first voucher issued on account of work done, except as otherwise provided in Section 9-2-113.
     Any collector omitting to do so is liable to a penalty of $10 for every such omission, but the validity of the special assessment, or the right to apply for and obtain judgment thereon, is not affected by such an omission. It is the duty of such collector to write the word “paid” opposite each tract or lot on which the assessment is paid, together with the name and post office address of the person making the payment, and the date of payment.
