Frequently Asked Questions

Drainage districts have been established for the drainage of surface waters from agricultural and other lands for the protection of said lands from overflow when said
protection is a public benefit or is conducive to public health, convenience, and welfare (Section 468.2, State Code of Iowa).

Drainage districts are established by the Board of Supervisors at the request of the landowners within the proposed district (Section 468.1). Petitions and actions to establish are kept in the minute books in the County Drainage office.

Assessments are made as necessary to pay for engineering costs, improvements, and repairs within a given drainage district.

Assessment or classification of land in a drainage district is based on the benefit that land is seen to receive from being in the district. The original assessed value of any parcel of land within a district was set when that district was established and is the basis for all future assessments unless the district is reclassified by the board (Section 468.49).

Under the Code of Iowa, Chapter 468, the County Board of Supervisors act as Drainage District Trustees in all District matters. The land owners of a particular district may, if they wish, elect their own trustees and maintain the district themselves. (Section 468.500)

Yes. The trustees are required by the Code of Iowa (Section 468.126) to maintain all drainage districts at their original capacity. Notice of repairs is only required when the cost will exceed $50,000 but less than the competitive bid threshold in Section 26.3.

No, unless the district is dissolved (Sections 468.250-468.261).

All drainage district records are kept in the County Drainage Office.

Drainage district repairs are generally done at the direction of the Supervisors/Trustees and requests for repairs should be directed to the Drainage Office. Other complaints, problems, or questions can be directed to the drainage clerk or to the drainage district trustees.

Property owners within a district pay for all its maintenance and repairs. An independent contractor hired by the trustees will do the work and bill the cost to the district. Members of the district pay based on the proportion of the original assessed value of their property to the original assessed value of the entire district.

Assessments are computed as a percentage of the original assessment which is based on the benefit that a property is seen to receive by being inside the district (see next question).

Assessments are based on the benefit a particular property receives from the district. You can consult district maps (available through the drainage clerk) to determine your property's location within the drainage district in relation to the ditch.

Drainage districts are not levied on a regular basis. When a district is levied the trustees set the percentage such that a surplus remains after all bills are paid. The district will not be levied again until its funds are depleted. Depending on the amount of work required in the district, some districts are levied every year while a few have gone 50 years or more without a levy. To find out when your district was last levied, contact the drainage clerk.
