A sand and gravel mining operation has been proposed for a location in San Francisco Township near County Road 50 and County Road 40.
Specifically, the operation would be on 184 acres of property in the township with part of the site bordering 159th St. and Joyce Road, according to images from the Environmental Assessment Worksheet (EAW). Actual mining is proposed for 37 acres within that site away from residential areas.
The mine is anticipated to be operational for 10 to 20 years, and an estimated 1.5 to 2 million cubic yards of material is expected to be extracted throughout its lifetime.
According to the EAW, one of the purposes of the project is to provide construction aggregates to surrounding communities.
“Quality construction aggregates are an essential component of road, infrastructure, buildings, and other public and private improvements,” stated the planning documents. “According to the Aggregate Resources Task Force, the statewide demand for construction aggregates is approximately 10.5 tons per person per year (Rukavina, 2000). Local aggregate resources are considered a regional asset.”
Ron Olson Construction, based out of Cologne, Minnesota, is proposing the operation which would include stripping, mining of sand and gravel, crushing, screening, recycling asphalt and concrete, hauling, and reclamation activities.
Reclamation will return the land to agricultural production.
