URGENT NEWS & CALL TO ACTION: Boulder County Board of Adjustment Hearing
Lafarge Holcim Aggregate Industries is appealing the Boulder County Land Use historic determination on June 16, 2020 regarding mining the Fredstrom gravel pit surrounding Pella Crossing in Hygiene, on N. 75th Street between St. Vrain and Hygiene Roads.
Land Use Director Dale Case determined that the Lafarge permit has lapsed and that administrative filing, reseeding, weed remediation, etc. are not sufficient to keep the mining permit active due to the Five Year Lapse Provision Land Use Code. This is a major and historic decision-it marks the first time that the Land Use Department has applied the 5 year lapse provision.
The Boulder County Board of Adjustment (BOA) will host a virtual hearing on the decision and Lafarge’s appeal on October 7th at 4 PM. The BOA determination could become the precedent for the application of the five year lapse provision and will shape the fate of North Boulder County.
1. Use your voice: Leave formal comment with the BOA today to share your opposition to gravel mining in the St Vrain Valley.
3. Attend the BOA hearing on October 7th at 4PM. Details for online participation and public comment will be posted on the Boulder County website. We will also have limited first-come, first-served capacity for a small gathering at the Shupe Homestead if you are healthy and would like to join us in person. Masks will be required, safety precautions will be strictly adhered to, and 6 feet will be maintained between all parties.

The agricultural open space and recreational opportunities in and around Hygiene and Lyons are cherished by many, but may soon be dramatically affected by an intensive surface mining operation, possibly lasting until 2033. A Special Use permit issued two decades ago would allow open pit mining in the geologically unique St. Vrain Valley, with the total area of the use approved at approximately 881 acres. Residents and visitors to the area would experience potentially serious health effects; the compromised availability and quality of water; environmental issues affecting wildlife and habitat; and community impacts such as traffic congestion from trucks and trains, as well as noise and light pollution.

Save Our St. Vrain Valley (SOSvv) is a community of concerned citizens. WE NEED YOUR HELP.  Please join us if you are:
