(a) The council may combine the hearings provided for in sections 12-10 and 12-27. If it does so, such determination shall be made in the resolution proposing to make the improvement or improvements, and the following provisions shall then be applicable to the proceedings: (1) The resolution need not specify the maximum estimated amount to be assessed on the unit of assessment nor fix the date of public hearing upon the proposed improvement, but shall direct the preparation by the responsible director or manager of the documents and data to be prepared by such person IMPROVEMENTS BY ASSESSMENTS § 12-28 as provided in sections 12-18 and 12-19 and in section 12-27 and if applicable shall include the request and direction provided in section 12-20. After the combined hearings, if the council determines to proceed with the improvements, the resolution specified in section 12-20 need not again direct preparation by the responsible director or manager of the documents and data as provided in sections 12-18 and 12-19. The clerk shall not cause the notices to be given as provided in section 12-10 until the documents and data have been so prepared by the responsible director or manager, and if applicable, by each cooperating department, and preliminarily approved by the council, at which time the council shall by resolution requiring not more than one reading for its adoption fix the date of combined hearings; provided that the map, details and plans and specifications specified in sections 12-19 and 12-20 shall be deemed to satisfy this requirement if such documents are determined by the responsible director or manager to be in such form and contain such information as is reasonably necessary to inform the owners and other interested parties at least generally of the nature and scope of the proposed special improvements. (2) The matters to be contained in the notices provided for in sections 12-10 and 12-27 shall be combined into single notices to be so published, posted and mailed; for the purpose thereof the total amount of the cost of the improvement shall be based on the estimated cost of the work to be included in bids when received, not upon the bid of the lowest responsible and reliable bidder as specified in section 12-27. (3) The council may request the responsible director or manager, to call for bids on all improvements to be constructed under contract to be received on or before the date of the combined hearings pursuant to the provisions of section (4) The responsible director or manager shall prepare an amended preliminary assessment roll based on any revisions in the estimate of the responsible director or manager or on the results of the bids received for improvements as the case may be and shall send said amended assessment roll to the council on or before the public hearing. (A) If the amended preliminary assessment roll shows a proposed amount of assessment for any of the assessment units to be assessed which is more than that shown on the preliminary assessment roll, then, unless the affected owner shall waive the same, the council shall postpone the public hearing and readvertise and mail an amended notice of hearing containing the amended preliminary assessment roll. Said readvertisement and mailing shall be done under the provisions of sections 12-27(c) and (d). Said postponed public hearing shall be conducted in the same manner as provided in section 12-27(e). (B) If the amended preliminary assessment roll shows a proposed amount of assessment for each of the assessment units to be assessed which is the same or less than the preliminary assessment roll, the public hearing shall be held as scheduled and the amended preliminary assessment roll shall be considered at said public hearing.
