Colorado Springs outlines mine subsidence risks and protections for homeowners

On April 16, 2025, the Colorado Mine Land Reclamation Board (MLRB) convened via Zoom to discuss critical issues surrounding mine subsidence in Colorado Springs. The meeting highlighted the mechanics of mine subsidence, its causes, and the Mine Subsidence Protection Program (MSPP) designed to assist affected homeowners.

Mine subsidence occurs when underground voids created by mining activities collapse, leading to surface depressions, cracks, and sinkholes. The presentation detailed various types of subsidence, including trough and chimney subsidence, which can manifest abruptly or gradually. Factors influencing subsidence include mining depth, age of the mine, and the structural integrity of remaining pillars. The Colorado Springs area, particularly neighborhoods like Cragmoor, has been identified as highly susceptible to subsidence due to its extensive mining history.

The MSPP, established in 1989, aims to mitigate the impact of mine subsidence on homeowners. To qualify for the program, properties must have been built before February 22, 1989, and be located in undermined areas. The program covers up to $100,000 in damages per occurrence, with a $1,000 deductible. Homeowners must undergo a baseline inspection to assess preexisting damage, which is not covered by the program.

During the meeting, board members discussed the importance of thorough investigations when homeowners report potential subsidence-related damage. The process includes evaluating structural distress, soil conditions, and historical data on subsidence in the area. Homeowners have the right to appeal decisions made by the MSPP regarding claims, with the MLRB serving as the final authority on disputes.

The meeting underscored the ongoing challenges posed by mine subsidence in Colorado Springs and the vital role of the MSPP in providing support to affected residents. As urban development continues over historically mined areas, the board's efforts to address these issues remain crucial for community safety and property protection.
