Board approves parcel split allowing type‑3 septic after soil borings show only 10‑inch separation

The Morrison County Board of Adjustment approved a variance on Aug. 18 to allow a proposed split of a 40‑acre parcel where soil borings found only a 10‑inch separation to the seasonally high water table, requiring a type‑3 mound septic system rather than a standard type‑1 drainfield.

Amy of Land Services presented the staff report, saying the applicant proposed to convey 35 acres and retain the existing home on 5 acres. “It was found that there is only a 10‑in separation to the water table, which requires a type three mound septic system,” she told the board and cited Minnesota rules governing septic system design. The property contains an extensive wetland complex, with higher ground near the road where building sites exist.

Board members discussed a wetland delineation completed by Soil and Water, noted multiple potential upland building spots, and raised driveway and sightline safety concerns for the road curve. Ripley Township and the county engineer participated in review; Amy said driveway placement will need to be coordinated with Public Works for safe ingress and egress. After answering the required findings, the board voted to approve the variance. The board noted the buyer will need to work with Public Works and obtain a road‑approach permit if and when a driveway is proposed.
