1. When any levee or drainage district has been established and the improvement constructed, the improvement shall be at all times under the supervision of the board of supervisors except as otherwise provided for control and management by a board of trustees and the board shall keep the improvement in repair as provided in this section. a. The board at any time on itsown motion, without notice, may order done whatever is necessary to restore or maintain a drainage or levee improvement in itsoriginal efficiency or capacity, and for that purpose may remove silt and debris, repair any damaged structures, remove weeds and other vegetable growth, and whatever else may be needed to restore or maintain such efficiency or capacity or to prolong its useful life. b. The board may at any time obtain an engineer’s report regarding the most feasible means of repairing a drainage or levee improvement and the probable cost of making the repair. Ifthe engineer advises, or the board otherwise concludes that permanent restoration ofa damaged structureis not feasible at the time, the board may ordertemporary construction itdeems necessary to the continued functioning of the improvement. Ifin maintaining and repairing tilelines theboard findsfrom an engineer’s report itismore economicalto construct a new line than to repair the existing line, the new line may be considered to be a repair. c. If the estimated cost of the repair does not exceed fiftythousand dollars, the board may order the work done without conducting a hearing on the matter. Otherwise, the board shall set a date for a hearing and provide notice of the hearing to landowners in the district by publication in the same manner as provided in section 468.15. However, ifthe estimated cost of the repair exceeds the adjusted competitive bid threshold, the board shall provide notice to the landowners pursuant to sections 468.14 through 468.18. The board shall not divide a proposedrepair into separate programs in order to avoid the noticeandhearing requirements of this paragraph. d. Notwithstanding paragraph “b”, if the estimated cost of the repair exceeds fifty thousand dollars or the adjusted competitive bid threshold, whichever is more, the board shall order an engineer’s report or a report from the soil and water conservation district conservationist regarding the matter which shall be presented at the hearing provided in paragraph “c”. The board may waive the report requirement if a prior report on the repair exists and that report is less than ten years old. At the hearing, the board shall hear objections to the feasibility of making the proposed repair. e. Following a hearing, if required in paragraph “c”, the board shall determine whether the repair isnecessary or desirable, and feasible. f. Any interested party has the right of appeal from such orders in the manner provided in this subchapter, parts 1 through 5. g. The right of remonstrance does not apply to a repair as provided in this section. 2. In the case of a repair, or the eradication of brush or weeds along the open ditches, not inexcess ofthe adjusted competitive bid threshold, where the board findsthat a saving to the districtwill result, the board may cause the repairs or eradication to be done by secondary road fund equipment, or weed fund equipment, and labor of the county and then reimburse the secondary road fund orthe weed fund from thefund ofthe drainagedistrict thusbenefited. 3. Whenthe board deems itnecessary it may repair or reconstruct the outlet ofany private tileline which empties into a drainage ditch of any district and assess the costs in each case against the land served by the private tile line. 4. a. For the purpose of this subsection, an “improvement” in a drainage or levee district in which any ditch, tile drain, or other facilityhas previously been constructed is a project intended to expand, enlarge, or otherwise increase the capacity of any existing ditch, drain, or other facilityabove that for which it was designed. b. When the board determines that an improvement is necessary or desirable, and feasible, the board shall appoint an engineer to make surveys as seem appropriate to determine the nature and extent of the improvement, and to file a report showing what improvement isrecommended and itsestimated cost, which report may be amended before finalaction. c. If the estimated cost of the improvement does not exceed fiftythousand dollars, the board may order the work done without conducting a hearing on the matter. Otherwise, the board shall set a date for a hearing on whether to construct the proposed improvement and whether there shall be a reclassification of benefits for the cost of the proposed improvement. (1) (a) The board shall provide notice to landowners in the district by publication in the same manner as provided in section 468.15. However, if the estimated cost of the improvement exceeds the adjusted competitive bid threshold, the board shall provide notice to the landowners pursuant to sections 468.14 through 468.18. (b) Notwithstanding subparagraph division (a), and in lieu of publishing the notice, the board may mail a copy of the notice to each address where a landowner within the district resides by first class mail ifthe cost of mailing isless than publication of the notice. The mailing shall be made during the time the noticewould otherwise be required tobe published. (2) The board shall not divide proposed improvements into separate programs in order to avoid compliance with this paragraph “c”. d. At the hearing, if required in paragraph “c”, the board shall hear objections to the feasibility of the proposed improvements and arguments for or against a reclassification presented by or for any taxpayer of the district. Following the hearing, the board shall order that the improvement itdeems necessary or desirable and feasible be made and shall also determine whether there should be a reclassification of benefits for the cost of the improvement. Ifitis determined that a reclassification of benefits should be made, the board shall proceed as provided in section 468.38. e. If the estimated cost of the improvement exceeds the adjusted competitive bid threshold, or the original cost ofthe district plus the cost of subsequent improvements in the district,whichever amount is greater, a majority of the landowners, owning in the aggregate more than seventy percent of the total land in the district, may filea written remonstrance against the proposed improvement, at or before the date set for hearing on the proposed improvement as provided in paragraph “c”, with the county auditor, or auditors in case the district extends into more than one county. If a remonstrance is filed, the board shall discontinue and dismiss allfurther proceedings on the proposed improvements and charge the costs incurred to date for the proposed improvements to the district. Any interested party may appeal from such orders in the manner provided in this subchapter, parts 1 through 5. However, this section does not affect the procedures of section 468.132 covering the common outlet. 5. Where under the laws in force prior to 1904 drainage ditches and levees were established and constructed without fixing at the time of establishment a definite boundary line for the body of land to be assessed for the cost thereof, the body of land which was last assessed to pay for the repair thereof shall also be considered as the established district for the purpose of this section. 6. The governing body of the district may, by contract or conveyance, acquire, within or without the district,the necessary lands or easements for making repairs or improvements under this section, including easements for borrow and easements for meander, and in addition thereto, the same may be obtained in the manner provided in the original establishment of the district, or by exercise of the power of eminent domain as provided for in chapter 6B. If additional right-of-way is required for any repair or improvement under this section, the same may be acquired in the same manner as provided for the acquisition of right-of-way in the original establishment of a district, except that where notice and hearing are not otherwise required under this section notice as provided in this subchapter, parts 1 through 5, to owners, lienholder of record, and occupants of the land from which right-of-way isto be acquired shall suffice. 7. In existing districts where the stream has by erosion appropriated lands beyond its original right-of-way and it ismore economical and feasible to acquire an easement for such erosion and meander than to undertake containment ofthestream in itsexisting right-of-way, the board may, in the discharge of the duties enjoined upon it by this section, effect such acquisition as to the whole or part of the course. Right-of-way so taken shall be classed an improvement for the purpose of procedure under this section. 8. Ifthe drainage records on file inthe auditor’s officefor a particular district do not define specifically the land taken for right-of-way for drainage purposes, the board may at any time upon its own motion employ a land surveyor to make a survey and report of the district and to actually define the right-of-way taken for drainage purposes. After the land surveyor has filed the survey and report with the board, the board shall fix a date for hearing on the report and shall serve notice of the hearing upon alllandowners and lienholder of record and occupants of the lands traversed by the right-of-way in the manner and for the time required for service of original notices in the district court. At the hearing the board shall specifically define the land taken for the right-of-way. Once established, the right-of-way constitutes a permanent easement in favor of thedrainage districtfor drainage purposes including the right of ingress and egress across adjoining land and the right of access for maintenance, repair, improvement and inspection. A person aggrieved by the action or failure to act of the board under this subsection may appeal only in compliance with sections 468.83 through 468.98.
