Drainage Easements in Faribault County, Minnesota

A public ditch on your parcel comes with a mandatory 16.5-foot buffer easement

Minnesota Statutes section 103E.021 makes it mandatory, on any drainage project where viewers have been appointed, to establish a permanent strip of perennial vegetation one rod (16.5 feet) wide on each side of a county open ditch, measured outward from the top edge of the constructed channel or to the crown of the leveled spoil bank, whichever is greater. This isn't the general, self-executing 2015 Minnesota buffer law that applies statewide to public waters -- it's a distinct, older drainage-law requirement, dating to 1977, that specifically attaches to public drainage systems once a redetermination, improvement, or certain petitioned-repair proceeding triggers the appointment of viewers. Where a Drainage Law buffer strip already exists on a given ditch, it satisfies the separate statewide Buffer Law's requirement for that same stretch, so a landowner generally isn't stacked with two independent buffer obligations along the same ditch -- but a landowner should still confirm which law's buffer, if either, currently applies to a specific parcel's ditch frontage, since the two have different enforcement mechanisms and different histories of when they attached.

Critically, the statute requires the drainage authority -- in Faribault County, the County Board acting as Drainage Authority -- to acquire the right-of-way for this buffer strip and pay the landowner damages for it, rather than simply imposing the strip as an uncompensated restriction. That compensation is what shows up as a specific easement payment whenever the county formally redetermines a ditch system's benefits and damages.

What the county actually pays: $8,000 per cropland acre, $800 for non-benefited or wooded acres

Faribault County's own recent drainage redetermination proceedings -- including Ditch CD69 and Ditch CD72 -- show the county's applied compensation formula for these statutory buffer easements: grass-strip cropland acres are compensated at $8,000 per acre, while non-benefited acres or acres in trees are compensated at $800 per acre, both paid as a one-time payment for a permanent easement rather than an ongoing lease or rental. Separately, and distinct from the 16.5-foot vegetation buffer itself, the county's drainage system carries a 100-foot access easement along each open ditch -- measured from the center of the ditch, minus the actual width of the open ditch channel, minus the 16.5-foot buffer strip already counted -- which the county and its contractors can use to access the ditch for maintenance, repair, and improvement work without needing separate landowner permission each time.

These figures come from specific, recent redetermination proceedings rather than a single fixed countywide rate schedule published independent of any particular ditch project, so a landowner should treat $8,000/$800 per acre as strong, recent evidence of the county's applied formula rather than a guaranteed number for every future proceeding -- rates can be revisited project to project. What is fixed by statute, not by county discretion, is the underlying 16.5-foot buffer-strip requirement itself and the requirement that the county compensate for it as a permanent easement.

What this means before buying agricultural land here

1. Ask the Drainage Department whether the target parcel borders, or lies within the benefited area of, one of the county's 113 public drainage systems -- more than 260 miles of open ditch and roughly 700 miles of tile run through the county, so this is a routine question for rural Faribault County land, not an edge case.
2. If the parcel borders an open ditch, confirm whether the 16.5-foot statutory buffer strip has already been established and compensated on that specific stretch, or whether a redetermination proceeding that would trigger it is pending or anticipated -- an anticipated proceeding could mean a future one-time easement payment, but it also means that strip of cropland will permanently come out of production.
3. Separately confirm the 100-foot access easement's practical footprint along any ditch frontage, since it can affect where a driveway, fence line, or accessory building can be sited relative to the ditch, independent of the narrower 16.5-foot vegetation buffer.
4. If a specific ditch system serving the parcel has a recent or pending repair/improvement project, ask about its assessment history -- a benefited landowner can be assessed for that project's cost even in a year with no easement payment activity.
5. Don't assume the $8,000/$800 per-acre figures from CD69 and CD72 will apply verbatim to a different ditch system or a future proceeding; get the Drainage Department's current position on compensation for the specific system in question.
