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 Drainage District Trustees at the request of the land owners within the proposed district (Section 468.6-468.8). Petitions and actions to establish are kept in the minute books in the County Auditor's 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 assessments unless the district is reclassified by the trustees (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.

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 $20,000 or 75% of the original assessed value of the district, whichever is greater.

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

All drainage district records are kept in the County Auditor's Office.

Drainage district repairs are generally done by the County Engineer and requests for repairs should be directed to that department. Other complaints, problems, or questions can be directed to the drainage clerk in the Auditor's Office or to the drainage district trustees.

Property owners within a district pay for all its maintenance and repairs. The County Engineer's Office or 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. Properties near the bottom of the district or adjacent to a district tile line will generally pay more than properties at the top of the district or that are not close to a district tile. This is because the tile lines run through the lowest areas which would have the worst flooding if no tile was present. You can consult district maps (available through the drainage clerk) to determine your property's location within the drainage district in relation to the district tiles.

Drainage districts are not levied on a regular basis. When a district is levied the trustees set the percentage such that a surplus (usually around $2,000) 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 two years while a few have gone 50 years or more without a levy. The norm is every 4-5 years. To find out when your district was last levied, contact the drainage clerk.

NO - Drainage districts are levied when district funds drop to zero. The levy creates funds to pay for future expenses, not past ones.

Delinquent drainage assessments become a lien on the property (Section 468.51). The property can then be sold for back taxes/assessments just as it can be sold for non-payment of property taxes (Section 468.158-.162).
