Quikrete Applies for Mining Permit Extension in Silverthorne

Summit Valley Horse Center
Quikrete, the current owners of the Peak Materials operation in Silverthorne, has applied with the Summit County Planning Commission to extend its Conditional Use Permit (CUP) to mine aggregate for an additional 15 years. According to the application...The application proposes continuing operating with the same approved uses as the previous 30 years and does not request to change any of the operating conditions, or site plan as outlined in the previous CUP. No new structures are proposed. Quikrete requests that the new permit allows the continuation of the existing operations for the next 15 years. According to the application, Quikrete’s operational lease term with the landowner extends until 2057.
The key question is when Quikrete finally depletes aggregate at its Peak and Maryland Creek Ranch site, where will it go next for material? Peak, then owned by the Kilgore Company, proposed to mine gravel on 80 acres purchased by the company from Julie Hillyard for $4 million back in 2018.
