Mitchell County supervisors hear lengthy debate after Planning & Zoning recommends denying proposed rock‑quarry rezoning

The Mitchell County Board of Supervisors spent the bulk of its May 5 meeting holding a public hearing on a request to rezone five parcels (10-22-300-012, -014, -015, -027 and -029) from Agriculture to Arterial Commercial to make way for a proposed rock quarry.

The county’s Planning & Zoning Commission had recommended denial after its April 9 public hearing, citing concerns about the project’s scope, driveway and entrance access, sight lines and impacts to nearby residences. A commission letter read into the county record said the board’s recommendation was 4–0 with one abstention and formally urged the supervisors to deny the rezoning.

Applicant representatives, including landowner Kurt Christensen, told supervisors the site offers exploitable limestone and that a local quarry would increase competition in the industry and produce jobs and tax base. “We’re looking at putting this project in to help create a competitive environment in that industry that we don’t have,” Christensen said, adding that most of the land would remain in farming if the project proceeds and that the owners would pursue borings and DOT driveway approvals as needed.

Neighbors and several township residents pushed back on safety and quality‑of‑life grounds. Speakers repeatedly raised sight‑distance concerns for a proposed driveway onto Highway 9 at the top of a hill—citing sun‑glare and limited visibility for westbound drivers—and urged a full, independent Iowa DOT review. One longtime nearby property owner said he had moved a driveway previously after DOT review because of safety; others asked why speed limits in the area had not been reduced previously.

Amanda, the county sanitation expert, told the board that wells and septic systems can be affected by nearby blasting and said the county had at least one prior case in which a well required remediation after quarry blasting. “Wells are kind of finicky,” Amanda said, and private‑well impacts have been a valid concern in county files.

Applicant operations representative Jeff said modern blasting is quieter and that quarries can be landscaped: “This is not what we use anymore,” he told the public, describing contemporary techniques that he said reduce perceptible impacts.

Several residents also said deed addenda for some lots included restrictions against commercial uses; one resident said he and others had signed an addendum agreeing the property would not be used for commercial purposes. The applicant acknowledged the point but said most lots in the plat did not contain that restriction.

After extended public comment the board took up a motion to deny the rezoning. The record shows a motion to deny was made and seconded; a roll call was recorded and the clerk announced, "Motion denied." The transcript records the roll call names but does not provide an explicit, line‑by‑line yes or no vote in the text beyond the clerk’s announcement.

What happens next remains procedural: the applicant said he had contacted the DOT and expected a report after a recent site visit; supervisors and residents said they would rely on DOT sight‑distance measurements and any formal DOT recommendations in considering future action. The Planning & Zoning Commission’s written recommendation and the extensive public record will remain part of the county file.

The board moved on to its next agenda items after closing the hearing at 9:46 a.m.
