Planning commission approves limited gravel‑driveway exception for large lots; applicant says local lots exceed draft minimums

Cannon Falls planning commissioners on July 21 recommended that City Council adopt a text amendment allowing a partial gravel‑driveway exception for certain large residential lots, after discussion about minimum length thresholds, drainage, aesthetics and construction cost impacts. The amendment applies to single‑family and two‑family lots of at least two acres and requires paved surfaces for the entry (25 feet from the street) and at least 25 feet leading to the garage or parking area; the staff draft set 100 feet as the minimum driveway length to qualify for the exception.

Why it matters: the change creates a limited carve‑out to the city’s general requirement that driveways within the city be paved, giving developers and future homeowners more options for long rural driveways while keeping paved surfaces at the public entrance and vehicle parking area. Commissioners debated whether the qualifying minimum should be raised from 100 feet to 150–200 feet; that proposed amendment was moved and then withdrawn after discussion and developer input.

Staff member Shelly told the commission that the staff‑recommended draft narrows the exception to residential lots of at least two acres with driveways of a stated minimum length. “Number 4 would be added for single family, two‑family lots with a minimum of 2 acres. The areas utilized for driveways that are at least 100 feet in length. The surface must have a pavement or concrete for at least 25 feet from the street accessing the driveway and for at least 25 feet leading to the garage entry or parking space,” Shelly said.

Mark Soska, who identified himself as representing Timber Ridge Development (JMH Land), told the commission the developer’s long driveways would meet a higher threshold. “The one to the southeast is 500 feet long, and the common one going the other way is a little over 300 feet long,” Soska said, noting that a 200‑foot minimum would cover the Timber Ridge lots under discussion. He also said adding another 50 feet of asphalt (for example) would cost roughly $6,000.

Commissioners discussed the trade‑offs: paving reduces dust and may help drainage near the house, but paving every long driveway increases upfront development costs that can be passed to homebuyers. One commissioner said the intent is to permit an accommodation for large rural lots and avoid requiring immediate upgrades when properties are annexed into the city; another said the 100‑foot minimum had been recorded from prior work‑session conversations with the applicant and staff.

The commission ultimately voted to recommend the staff draft (100‑foot minimum, 25 feet paved at each end) to the City Council. A separate motion proposing to amend the draft to require a 200‑foot minimum was made, seconded and later withdrawn; the record shows the commission approved the staff draft by voice vote.

Next steps: the planning commission forwarded its recommendation to the City Council for final action. If the council adopts the ordinance, it will apply citywide to eligible residential lots and to future developments that meet the two‑acre threshold. The planning commission and staff noted that the rule does not change paving requirements for smaller lots or for streets and curbed public rights of way; public‑right‑of‑way and MnDOT/county road conditions may alter how a given lot is treated in practice.
