I. INTRODUCTION Scope of Work

In the fall of 2016, Bolton & Menk, Inc. was appointed engineer to review the facilities under the jurisdiction of the Drainage District No. 2 Board of Trustees and recommend necessary repairs or improvements. Upon review of the existing system, records in the office of the County Auditor and discussions with the Board of Trustees, the scope has been modfied to include re-establishment of the repair elevation and cross section of the Subdrainage District No. 1 Open Ditch, acquisition of the Lateral 1 open ditch as a district facility and review of existing right-of-way for both open ditches.

Location

Drainage District No. 2, Subdrainage District No. 1 Open Ditch serves an area lying between the Union Pacific Railroad and the west bank of the Pigeon Creek Main Open Ditch in Sections 14 & 23 of Crescent Township (T-76-N; R-44-W) in Pottawattamie County. The sole improvement in the district is an open ditch approximately 7500 feet long lying along the east side of the UPRR tracks.

The contributing watershed to Subdrainage District No. 1 covers approximately 940 acres which includes the lateral 1 watershed, in Sections 11, 13, 14, 23, 24 and 26 of Crescent Township (T-76-N; R-44-W). The schedule of lands currently listed for benefit in Drainage District No. 2, Subdrainage District No. 1 is on file in the Pottawattamie County Auditor’s Office.

History

September 27, 1917 – Engineer’s Report

Land is over washed by overflow from Pigeon DD 2. Recommended that the west bank of Pigeon DD 2 be raised from station 0 in Section 13 to the railroad embankment.

Recommends construction of a ditch with 6’ base and 1.5:1 slopes.

Station 0 is north bank of Pigeon DD 2 and ditch extends to the old channel of pigeon creek in the SW ¼ of Section 14-46-44 parallel to railroad right-of-way

Recommends a bulkhead and floodgate or tube and floodgate to prevent back water from DD 2. 60 LF of 60” Dia CMP with cast iron gate was built

Right-of-way is 60 feet wide

October 6, 1917 – Petition to Establish Subdistrict

Open Ditches in Sections 16, 21 and 22

September 24, 1924 – Engineer’s Report

Emergency repairs to the ditch recommended due to severe flooding caused by silted lower end

December 2, 1951 – Engineer’s Report (Filed by SCS)

Recommends “reconstruction” of channel to an 8’ base, 2:1 slopes and 0.05% grade.

II. INVESTIGATION Survey of the Drainage District No. 2 facilities was made during the spring of 2018. This survey was used to determine the repair grade of the Subdrainage District No. 1 Open Ditch.

The records of the district show the repair cross section of the open ditch was improved in 1951 to an 8 foot bottom with 2:1 sideslopes and a grade of 0.05%. The capacity of this repair cross section exceeds the design standards for drainage ditches in Iowa as recommended by the Iowa Drainage Guide.

Also found during review of Sub Drainage District No. 1 Open Ditch was a small lateral ditch running east and north from the main ditch at station 43+05. This lateral recieves water from approximately 640 acres, or 68% of the full Sub 1 watershed. Because of the large contributing watershed, we believe it to be beneficial for the district to acquire Right-of-Way containing the ditch and maintain the channel as a district facilty to ensure proper drainage within the Sub 1 benefiting area.

District Right-of-Way

The existing right-of-way was purchased at the establishment of the district. The right-of-way widths were specified in the original Engineer’s Report to be 60 feet measured from the east right-of-way line of the Union Pacific Railroad track in Sections 14 and 23. The existing rights-of-way are adequate to contain the channel, though no access for maintenance is available within the existing easement.

The table below lists the parcels for which Sub 1 currently holds rights-of-way for maintenance of the open ditch:

III. PROPOSED WORK We recommend the district acquire right-of-way for and assume maintenance of the the privately built lateral ditch in Section 23-76-44 described previously in this report. This lateral provides necessary drainage to a large portion of the sub district and would therefore be a benefit to those lands.

Included with this report is a plan set showing the repair grade and cross section of the Sub 1 Open Ditch. This plan set also includes our recommended repair grade and cross section for the lateral ditch which we will hereby refer to as Lateral 1.

We find that the proper repair grade and cross section of the Lateral 1 Open Ditch is a 4’ wide bottom with 2:1 sideslopes and a grade of 0.09%. The design flowline of the Lateral 1 Open Ditch corresponds to that of the Sub 1 Main Open Ditch at station 43+05 of the main. This repair cross section exceeds the recommended capacity set forth in the Iowa Drainage Guide.

Main Open Ditch Right-of-Way

The existing 60 foot Right-of-Way is only wide enough to contain the Main open ditch. We recommend an additional 20 feet of right-of-way be acquired along the east side of channel to allow regular maintenance of the facility.

Lateral 1 Open Ditch Right-of-Way

Additional right-of-way will need to be acquired to maintain the Lateral 1 Open Ditch. Because of the shallow depth of the lateral ditch, we recommend a 60 foot wide right-of-way centered on the ditch.

Total Right-of-Way Recommended (Sub 1 Lateral 1 Open Ditch) 5.14

If right-of-way is to be acquired, an appraisal commission, made up of two landowners from the county and the engineer, are appointed to recommend fair payment. The right-of-way appraiser’s report is considered at a continued or separate public hearing prior to adoption.

Drainage district rights-of-ways are exempt from real estate taxes and drainage district assessments. Under Iowa law, landowners have the right to the beneficial use of the spoil bank in the right-of-way subject only to the district’s use of the right-of-way to monitor, protect, and maintain the open ditch.

Because the landowners will retain the rights of benefical use, right-of-way is generally compensated at far less than market value. Assuming a compensation rate of $400 per acre of right-of-way, the estimated cost to the district would be $1,400 for the Main open ditch and $2,100 for the Lateral 1 open ditch for a total of $3,500.

IV. ASSESSMENT SCHEDULE REVIEW Benefited Lands Not Now Assessed

There are approximately 190 acres within the Drainage District No. 2 Subdrainage District No. 1 watershed which have never been assessed for benefits received from district facilities. This area is shown on sheet A.02 of the attached plans.

We recommend that all lands which convey water to the facilities of Drainage District No. 2 Subdrainage District No. 1 be annexed.

Existing Assessment Schedule Review

Appendix A contains a map showing the existing assessment schedule for the Subdrainage

Page 8: Engineer’s Report for Record of Facilities · DD 2 Sub 1 Record of Facilities ǀ P12.111254 Page 1 . I. INTRODUCTION . Scope of Work In the fall of 2016, Bolton & Menk, Inc. was

District No. 1 benefited area. The existing schedule was established at the start of the district and has not been changed since. Considering the age and the general change in reclassification procedures starting in approximately 1970, the current schedule is not wholly inequitable. However, with the annexation of additional lands to the district and the acquisition of a new lateral as a district facility we recommend reclassification to balance the costs between the lateral and main ditches.

If reclassification is ordered, two schedules will be setup, the first for the Main Open Ditch and a second for the Lateral 1 Open Ditch. The cost to create these two schedules will be approximately $5,000-10,000.

General Reclassification Methodology

The process of reclassification uses several factors to equitably spread project costs based upon benefits received. The three common factors are; Use, Proximity and Wetness.

The Use Factor takes into account how much of the facility is required to bring an outlet to a particular location. The more a facility is used by any given property, the higher the use factor on that property. A parcel using one mile of a facility should pay less than a parcel using 5 miles of the facility.

The Proximity Factor takes into account the portion of the outlet provided. Lands nearer to the tile or ditch receive a higher assessment because they have easy access to district facilities. Lands farther from the facility must invest in additional private drainage to access the facility. A 40 acre tract which is crossed by a tile should pay more than a 40 acre tract a mile away which must build a private system to reach the tile.

The soil drainage class accounts for the soil types’ varying natural wetness and need for drainage. Wet soils in a pothole are high because the soils have more need for drainage than drier soils on the hill tops.

Many other considerations may be necessary to achieve equitable assessments.

V. DISCUSSIONS & RECOMMENDATIONS Acquistion Recommended. We recommend the district accept the existing privately dug lateral open ditch as a district facilty. The district would assume all future maintenance of this lateral open ditch.

Right-of-Way Recommended. We recommend the district purchase a permanent right-of-way encompassing the existing privately dug lateral open ditch and widen the exisitng right-of-way on the main open ditch. This right-of-way would be used to maintain the ditch as a district facility, protecting the drainage rights of those lands which drain to the channel.

Annexation Recommended. Approximately 20% of the lands which drain to the improved outlet provided by Drainage District No. 2 Subdrainage District No. 1 (190 acres) are benefited by district facilities, but have not been assessed for maintenance costs of the facilities. In order for these lands to now be assessed to help pay for future maintenance, it is necessary to bring them into Drainage District No. 2 Subdrainage District No. 1 by annexation procedures described in Iowa Drainage laws. Annexation procedures are estimated to cost approximately $5,000.

Reclassification Recommended. The inclusion of approximately 190 acres of land and the acquisition of new district facilities necessitates reclassification of the district to create an equittable basis upon which to spread the costs of future maintenance.
