Transforming a Colorado mine into community green space

August 18, 2025

Once a prominent “scar” on the Colorado Springs landscape, the Pikeview Quarry is now a model for responsible mine closure and environmental transformation. Our long-term involvement in reclaiming the site—from early planning during operations to engineering around steep highwalls and restoring native vegetation—was key to the project’s success.

Working alongside Castle Aggregates, the City of Colorado Springs, and the U.S. Forest Service, we helped transform a former limestone quarry into a safe, sustainable, and community-focused green space. The project included stabilizing the mountainside, planting over 31,000 native plants and trees, and preparing the site for future recreational use.

Pikeview exemplifies how thoughtful mine closure and strategic asset transformation can unlock long-term value—setting a global precedent for sustainable progress at legacy mine sites.
