Garage Over a Utility Easement and an Unplatted Gravel Drive
A 1968 plat in Washington County shows Lots 1 through 6 fronting a cul-de-sac. The plat dedicates a 30-ft-wide 'drainage and utility easement' across the rear 10 ft of Lots 1–6 and a 20-ft-wide 'access easement' from the cul-de-sac to Lot 6. The access easement was never paved or improved. Since 1999, the owners of Lot 5 and Lot 6 have used a gravel drive that lies 12 ft west of the platted access easement, crossing Lot 5 to reach Lot 6; each owner has maintained it, and no permission was ever requested or given. The Lot 6 owner now wants to build a detached garage over the platted drainage/utility easement at the rear of Lot 6 and also wants a survey that establishes the gravel drive as a prescriptive access easement. The utility company has an existing 8-inch sanitary sewer in the platted easement.
1. Can the Lot 6 owner build the garage over the platted drainage and utility easement? Explain.

Not without first resolving the easement rights. A drainage and utility easement is a nonpossessory right; the Lot 6 owner retains the fee and may use the surface if the use does not unreasonably interfere with the easement holder's rights. A detached garage is a permanent structure placed directly over an existing 8-inch sanitary sewer. That is likely an unreasonable interference because it blocks access for maintenance, repair, and replacement. The owner should not rely on the idea that 'it is my lot.' The utility company's consent, an easement relocation, or a vacation of the easement would be needed, and local building-permit review may also require proof that the structure avoids the easement. The surveyor should show the easement, the sewer, and the proposed garage footprint, and should advise the owner to obtain utility and legal approval before construction.
2. Evaluate the claim for a prescriptive easement for the gravel drive.

A prescriptive easement in Minnesota requires use for the statutory period-generally 15 years-that is open, continuous, adverse under a claim of right, and exclusive in the sense that the use is not shared with the general public. The gravel drive has been used since 1999, more than 25 years, and it is visible and maintained. The critical issues are adverse use and permission. If the owners used the drive as a neighborly accommodation, the use may be permissive and not prescriptive. If Lot 6's use crossed Lot 5 without permission and both owners treated the drive as the access, the facts support a prescriptive claim, but a court must decide. The drive's location 12 ft west of the platted access easement creates a separate issue: the platted easement may still be the legal access, while the gravel drive is an additional physical use. The surveyor should not label the drive as a prescriptive easement without adjudication.
3. What should the survey show if the prescriptive claim is not adjudicated?
Read the worked answer
Show the platted 20-ft access easement, the platted 30-ft drainage/utility easement, the sewer, and the gravel drive as a physical occupation line. Label the drive as 'gravel drive-physical use, prescriptive claim not adjudicated' rather than as an established easement. Show the 12-ft offset between the drive and the platted access easement. Explain that the survey does not establish prescriptive rights; a declaratory judgment, a quiet-title action, or a written easement agreement is needed. The client should also be warned that building the garage over the utility easement requires separate utility approval and may affect the value and marketability of the lot.
