I. INTRODUCTION
SCOPE OF WORK
The purpose of this report is to provide information relative to drainage relief as requested by a landowner of Joint Drainage District No. 1 in Story and Hamilton Counties, Iowa (JDD1). The Joint Board of Supervisors acting as trustees appointed Kent L. Rode, P.E., Bolton & Menk, Inc. to complete the necessary preliminary survey, study, and engineering report.
This report addresses landowner requests for facility repairs associated with the Main Open Ditch. This report examines the conditions that would be necessary to restore the drainage efficiency of the Main Open Ditch to its original planned condition. A copy of the drainage petition is attached with this report in Appendix A.
LOCATION & DISTRICT FACILITIES
The watershed of JDD1 lies within Story and Hamilton Counties, located generally west of Story City, Iowa. The watershed of JDD1 is located in Sections 2, 3, 4, 9, 10, 11, 14, 15, 16, 22, 23, and 26 of Lafayette Township (T-85-N, R-24-W) in Story County, and Sections 27, 28, 33, and 34 of Ellsworth Township (T-86-N, R-24-W) in Hamilton County.
The Main Open Ditch of JDD1 is approximately 4.75 miles in length. The outlet of the Main Open Ditch is the Keigley Branch of the South Skunk River, near a bridge on 550th Ave. between sections 25 and 26 of Lafayette Township. Going upstream from the outlet, the open ditch goes in a northwest direction for approximately 3.75 miles. During this stretch it crosses underneath 140th St., US-69, Union Pacific Railroad, 130th St., and 120th St. When the open ditch reaches 530th Ave. it turns north and runs parallel with 530th Ave. for approximately 1 mile. It ends at a headwall approximately 1/3 mile north of the 110th St and 530th Ave intersection.
The water from JDD1’s Main Open Ditch outlets into the Keigley Branch of the South Skunk River. The South Skunk River merges with the North Skunk River to form the Skunk River which eventually outlets to the Mississippi River.
HISTORY SUMMARY
Bolton & Menk conducted an investigation based on records from the Story County
Courthouse. This information was gathered in order to better understand the drainage district’s history. A summary of events based on these records is as follows:

July 16, 2013 – Removal of Trees and Brush from the Main Open Ditch, Completed in 2015
2017 – Open Ditch Sprayed to Prevent Tree Regrowth
II. INVESTIGATION
SURVEY & INVESTIGATION
The petition which was provided to Bolton & Menk, requested an open ditch cleanout be performed to remove siltation buildup and resolve issues with inundated tile outlets. There were also concerns from landowners about trees growing along the Open Ditch that need to be removed. A survey was conducted to investigate these issues.
During the spring of 2021, a field review and preliminary survey were performed on the Main Open Ditch of JDD1. Topographic data was gathered along the open ditch to determine the existing sediment levels. Additionally, topographic data was obtained for inline structures on the open ditch as well as pipe elevation entering the ditch. A typical open ditch cross section was found in the district history and used to determine the current ditch capacity.
Further investigation of the Main Open Ditch included a drone flight to observe damages to the facility and get an overall condition of the Main Open Ditch. The following photos detail some of the damages to the Open Ditch.

CAPACITY ANALYSIS
From the information gathered in the field investigation and history search the capacity of the current system could be determined. The existing dimension of the Main Open Ditch vary along the length of the ditch, with 8ft wide bottom in the lower sections of the district and 6ft bottoms in the upper sections. The grade for the facility could not be found in past records, so it was set for this project using hard bottom shots that were obtained during the preliminary topographic survey. The history of the district shows the side slopes of the Main Open Ditch were originally described as 1:1 side slopes. The existing side slopes vary significantly throughout the length of the ditch anywhere from vertical to 2:1 side slopes. It is recommended that the side slopes be graded to a minimum 1.5:1 to provide greater stability in an effort to reduce side sloughs and the resulting siltation of the ditch bottom.
III. PROPOSED REPAIR
REPAIR SUMMARY
The investigation has confirmed the need for drainage relief within the district. A clean out of the open ditch is recommended to restore the drainage capacity of the facility to the original planned capacity. Iowa Code Chapter 468.126 states “… the board shall keep the improvement in repair” and “may order done whatever is necessary to restore or maintain a drainage or levee improvement in its original efficiency or capacity”. This cleanout would restore the original slope, shape, and capacity by creating the appropriate cross section along the open ditch. The open ditch would also have all trees and debris removed within the existing district right-of-way. The spoil material would be uniformly leveled and shaped to a typical cross section with a relatively flat top (2% slope) that is 14-18 feet wide, adjacent to the ditch with a 10:1 back-slope onto the adjacent land. These leveled berms would be placed in locations that would minimize disturbance of existing farm buffer zones. Where needed, new CMP tile extensions would be placed on the ends of field tiles entering the open ditch and new CMP surface drains would be installed at required locations as well as replacing existing surface drains. All tile extensions that are replaced that have animal guards will have the animal guards replaced as well.
WORK LIMITS & DAMAGES
Landowners are entitled to full reimbursement for damages resulting from the work on lands outside of open ditch rights-of-way. These damages will be established at a project completion hearing after the work is complete. The contractor will be assigned temporary work limits along each side of the ditch to allow for construction activities. The work limits for the open ditch will be set at approximately 35 to 50 feet outside of the toe of the spoil pile of the ditch.
It is anticipated that the repair work will commence in the Spring of 2022. Crops that are damaged during construction would be paid for by the district based on crop appraisals. The construction zone would be minimized, and the work scheduled to minimize the loss of crops.
Buffer Strips may exist within the work area. Seeding of these areas is typically performed by the landowner with reimbursement being made at the project completion hearing. Seed mixes for these lands is often very specific for the type of conservation practice which is utilized.

IV. OPINIONS OF PROBABLE COST
The cost estimate for the repair option is contained in Appendix B. This estimate represents our best judgment of the probable cost based upon our experience with similar projects. The quantities and unit costs for construction are believed to be reasonably accurate for use in this report and hearing. Actual costs are subject to the market for the respective components and to other economic forces. These estimates carry no actual or implied guarantees.
The Engineer’s Opinion of Probable Assessable Cost for the Main Open Ditch Repair Project is estimated at $490,000.00 for an average cost of $235.00 per acre.
V. DISTRICT RIGHT-OF-WAY
Open ditch Right of Ways are essential to maintain district quality and efficiency. These right of way purchases include the right of ingress and egress across adjoining land and the right of access for maintenance, repair, improvement, and inspection. A review of the existing right-of-way for JDD1 Open Ditch was preformed, starting with the district history found at the Story County Courthouse. The Landowner records for each ¼, ¼ section of land were examined for the existence of the open ditch right-of-way. It was determined that a right-of-way does exist however, it is not accurately defined on property cards and can vary along the length of the facility.
Under Iowa Code Section 468.27 Dismissal or Establishment – Permanent Easement – second paragraph “Following its establishment, the drainage district is deemed to have acquired by permanent easement all right of way for drainage district ditches, tile lines, settling basins, and other improvements, unless they are acquired by fee simple, in the dimensions shown on the survey, plat and profile, if one is made.” And, under section 468.126 Repair, Subsection 8 – “If the drainage records on file in the auditor’s office for a particular district do not define specifically that 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 actually define the right or way taken for drainage purposes.” Typically, it is necessary to have a minimum width of right of way to contain the top width of the open ditch and have 20 feet on each side for the ditch for access. The current top width of the open ditch is approximately 60 feet. Therefore, to provide 20 feet on each side of the ditch would necessitate a width of right of way for 100 feet.
Drainage district open ditch right of way are exempt from real estate taxes and drainage assessments. Therefore, deduction should be made to the new acres of those affected parcels and the property records for those affected parcels should be adjusted accordingly. Under Iowa law, landowners have the right to beneficial use of the spoil bank in the right of way subject only to the districts use of the right of way to protect and maintain the open ditch.
VI. ANNEXATION
Upon review of the existing watershed and assessment boundary, it was found that lands that benefit from the existing district facilities are not assessed for the benefit they receive, and land that is not benefitting from the existing district facilities are assessed for benefits that they do not receive. There are approximately 475 acres that are outside the existing district assessment boundary but drain to the existing facilities of the district and should be added to the schedule of JDD1. The Joint Board of Supervisors are able to annex these lands under Section 468.119 of the Iowa Code which states “… if the board become convinced that
Prepared by: Bolton & Menk, Inc. Joint Drainage District No. 1 ǀ 0P1.123169 5 Main Open Ditch Repair
additional lands contiguous to the district, and without regard to county boundaries, are benefited by the improvement to said district as contemplated in Section 468.126, the board may adopt with or without a petition from owners of the proposed annexed lands, a resolution of necessity for annexation of such additional land.”
It would be cost effective to perform this annexation as part of the proposed project. Most landowners now in the drainage district would likely support the annexation; those being annexed would tend to be opposed. It should be emphasized to the owners of the annexed lands that the assessments are based upon relative benefit and that if the benefit is small, the assessment is also relatively small.
It should be noted that the number of acres stated to be annexed in this report is just a preliminary estimate. The actual number of acres annexed is subject to change as our watershed model is farther defined.
We recommend annexation of all those materially benefitting areas as they have the specific benefits of being able to drain their land to the facilities of the district and have surface drainage which flow to the facilities of the district.
VII. RECLASSIFICATION
If a large area of land is annexed into the district, it may be in the best interest of the district to order a reclassification. Section 468.65 of the Iowa Code allows the Board of Supervisors to order a reclassification if they become convinced of inequities in the current assessment schedule, “… the board may consider whether the existing assessments are equitable as a basis for payment of the expense of maintaining the district and of making the repair, improvement or extension. If they find the same to be inequitable in any particular, they shall by resolution express such findings and, … order a reclassification”. Reclassification would develop schedules that would be used to allocate project expenses based off benefit received. Benefit is determined by reviewing factors for each 40-acre parcel or subdivide thereof. These factors include but are not limited to property wetness, facility usage, facility proximity, land use, and property area. Additionally, a separate schedule would be developed for each facility so that only those landowners who benefit from a facility would pay for facility installation and maintenance. A separate hearing is held for reclassification which would include separate landowner notifications.
Typically, reclassifications are performed after a project is completed to avoid the possibility of potential changes during construction that could alter the calculations of benefit. However, an option exists to perform a preliminary reclassification of the drainage district based on estimated costs to give landowners a better understanding of the amount of benefit the will receive and to help in their decision to support the improvement project.
The preliminary reclassification would not have the input of reclassification commissioners as required by the Iowa Code. However, it would be a good approximation of benefit received and much better than the current schedule.
VIII. BUFFER STRIPS
It appears there may be some farm program buffer strips in place along the open ditch. There are some manageable drawbacks which must be addressed by the owners of the buffer strips. If farm program buffer strips do exist, the destruction of buffer strip vegetation by spoil placement or leveling from cleaning the open ditch places the landowner in violation of farm
Prepared by: Bolton & Menk, Inc. Joint Drainage District No. 1 ǀ 0P1.123169 6 Main Open Ditch Repair
program conservation rules. The penalties can include loss of the CRP contract, forfeiture of back CRP payments, and penalties. To avoid these, landowners must request a waiver from the USDA Farm Service Agency County Committee. The county committee will grant waivers for ditch maintenance if seeding restoration in compliance with NRCS requirements is completed. If the work on the open ditch is authorized, all farm program buffer strip owners along the ditch must independently seek the FSA County Committee waivers. This process will take two or three months and should be initiated immediately if ditch maintenance is authorized.
IX. WATER QUALITY
The hydrologic impacts to tile drainage entail a complex interaction of processes dependent upon landscape, climatic and human influences, watershed scale, soil permeability and rainfall event size. There is a popular and often accepted idea that an increase in subsurface drainage facilities adds to an increase in both peak and total rainfall values thereby increasing flooding. Recently published research from the University of Iowa’s IIHR – Hydroscience and Engineering Center refutes that perception. This University of Iowa report was the result of a water model study of the Clear Creek Watershed in Iowa and Johnson Counties and found that an increase in field tile and subsurface drainage decreases peak flows for most storm events. The field scale DRAINMOD model was used in the research in conjunction with a simplified routing equation to analyze the impact of tile drains in the Clear Creek Watershed.
However, additional steps are required to slow, impound, or infiltrate water in order to receive benefits in water quality. Water quality is a growing topic throughout the nation and more recently throughout Iowa. The particle loads and nutrient levels within drainage water is a concern that is receiving increased scrutiny. Processes and reduction practices are being developed and incorporated on farms and into projects throughout Iowa which reduce nitrogen loss and improve water quality. Enhancement of water quality is possible through many different drainage applications that can see both immediate and long-term benefits.
We encourage the landowners of this District to consider multi-purpose drainage management, which incorporates Best Management Practices (BMPs) which utilize effective measures aimed at reducing sediment and nutrient loading and improving water quality. These BMPs are divided into three (3) areas: preventative measures, control measures, and treatment measures.
Preventative measures that can be applied throughout the watershed include crop rotation, cover crops, residue management, and nutrient management. These measures are aimed at controlling sediment, minimizing erosion and nutrient loss, and sustaining the soils health, all without dramatically changing the current land use of the landscape.
Control measures are practices aimed at improving water quality directly associated with the flow of water by reducing peak flows, providing in stream storage, sedimentation, and nutrient uptake. Examples of control measures include alternative tile intakes, grassed waterways, two (2) stage ditches, water control structures, and controlled subsurface drainage. These practices are directly linked to the conveyance of subsurface tile water or open channel ditch flow.
The function of treatment measures is to improve water quality by directly removing sediment and nutrients from the subsurface or surface water flow throughout a watershed. Examples of treatment measures include surge basins (storage ponds), filter/buffer strips,
Prepared by: Bolton & Menk, Inc. Joint Drainage District No. 1 ǀ 0P1.123169 7 Main Open Ditch Repair
wetland restorations, woodchip bioreactors, and water and sediment control basins (WASCOBs).
These practices may be incorporated to either the public or private drainage systems.
Funding options are available to landowners through the Environmental Quality Incentives Program (EQIP) and the Iowa Water Quality Initiative. EQIP is a voluntary program that provides financial assistance to individual landowners for various conservative practices as identified above. Also, the State of Iowa through the Iowa Water Quality Initiative provides cost share funds to participating landowners to voluntarily install nutrient reduction practices.
A unique opportunity may exist when a wetland is created within the district for the treatment of the tile and/or surface waters of the watershed. A properly sized and created wetland may be able to be utilized as a mitigation site for any farmed wetlands that are found within the drainage district. With the possibility of a large share of the created wetland being funded by the Iowa Water Quality Initiative program, any potential farmed wetlands could be mitigated at a much-reduced cost.
If there is landowner interest in any of these water quality features and funding options, further study and review would be required to select, site, and fund the water quality measures appropriate for the area.
X. SUMMARY & DISCUSSION
This report has confirmed the need for drainage relief for Joint Drainage District No. 1. The work described herein for the Repair Option can accomplish that relief. We recommend proceeding with the Repair Option. The proposed repair is considered to be of public benefit and is conducive to the public health, convenience, or welfare.
Recommendations
Repair Recommended
This report has confirmed the need for drainage relief for Joint Drainage Districts No. 1. The existing Main Open Ditch has siltation that requires removal along with damaged side slopes that needed repaired. There are surface drainpipes that need to be repaired along with rusted and damaged CMP tile extensions that should be replaced. Also, trees and other debris in the right of way will need to be removed so work can be completed. The proposed repair is considered to be of public benefit and is conducive to the public health, convenience, or welfare.
Right-Of-Way Recommended
Because of inconsistency of the existing right-of-way along the Main Open Ditch, it is recommended that right-of-way be defined as 50 feet each side of centerline in order to facilitate maintenance of the Main Open Ditch now and into the future.
Annexation and Reclassification Recommended
It is recommended that annexation be considered to bring in the approximately 475 acres that currently benefit from the facility but are not assessed for the benefit they receive. If these areas are annexed into the district reclassification would be recommended to fairly distribute the costs of maintenance, as well as any repair or improvement to the district.
Prepared by: Bolton & Menk, Inc. Joint Drainage District No. 1 ǀ 0P1.123169 8 Main Open Ditch Repair
Installment Payments
Iowa drainage law allows for drainage district costs for large projects to be paid between ten to twenty years at the discretion of the Board of Supervisors. Typically, the board would spread assessments of the magnitude contemplated in this report over ten years. Be reminded that final individual assessments are based upon benefits and that some parcels will likely bear two to three times the average per acre costs.
Recommended Steps
It is recommended that the Joint Board of Supervisors acting as trustees for Joint Drainage Districts No. 1 take appropriate action, with legal guidance, to accomplish the following:
1. Tentatively approve this engineer’s report and schedule a public hearing to receive and consider the input of district landowners.
2. Adopt the repair alternate recommended for construction, modified as deemed appropriate, to satisfy the desires of the district.
3. Establish a uniform width of ROW along the existing Main Open Ditch and direct the Assessor to make the necessary adjustments in property records.
4. Direct the engineer to prepare final plans and specifications for the adopted plan and proceed toward a bid letting.
5. Initiate annexation of benefitted lands not on the assessment schedule. A separate report on annexation and public hearing on the annexation report would be required.
6. Initiate reclassification of benefits for DD120. A separate commissioners’ report on
reclassification and public hearing on the commissioners’ report would be required.
