Asphalt & Gravel Pit

Knife River asphalt plant and gravel pit on Missoula’s north side. The proposed Riverside Contracting asphalt plant and gravel pit could be 3 times this size.

As you may have heard Riverside Contracting, Inc. has received an approved permit to open an asphalt plant, gravel pit open mine, and gravel crushing operation, which will be located at the T intersection of White Coyote Road and Martz Drive. The permit would be for 25 years and produce 1,000,000 cubic yards of material.

Proposed Asphalt and Gravel Pit in Arlee Montana

In March 2021 Montana House Bill 599 was passed. This bill drastically changed the permitting process for open pit mines. The Montana Legislature changed the law to make it easier for these plants to be set up right next to people’s homes.

Currently Missoula County is making it difficult for new gravel pit operations, so industrialists are looking elsewhere to set up gravel operations where there aren’t large populations opposed to them.

We have several concerns about this project, and it will take a lot of effort by our community in the form of gathering information, meeting with officials, and meeting with state and local politicians to answer those concerns. It is our hope that we can all come together to help shape the future of the Jocko Valley.

Permitting this kind of an operation is not just a threat for the moment, now that the permit has been granted the property value of that land will rise (and the rest of ours will fall). Even if Riverside Construction does not set up the plant, the permit will be a boon to anyone that wants to buy the property and open up a gravel pit without the hassle of continued major opposition.

Jocko Valley is a wonderful place to live and we as a community need to preserve the things we value most. Please share our website and participate however you are able.
