PDH Day: Domestic and International Adaptive Reuse of Aggregate Pits and Quarries by Steven Stokowski, PG, CPG

Depleted sand, gravel, and crushed stone quarries have long offered valuable landforms ready for adaptive reuse. Some of the earliest U.S. examples date back to 1800s Massachusetts, where former sand and gravel pits became well-drained sites for government buildings, homes, and commercial development. Today, reclaimed aggregate properties across the country support golf courses, residential communities, malls, strawberry farms, office parks, solar farms, deep-water quarry cooling systems, emergency water reservoirs, and even hotels. This trend is growing internationally as well, with notable projects such as the InterContinental Shanghai Wonderland Resort and the proposed Sac-Tun Cruise Port and tourist destination in Mexico showcasing the global potential of quarry transformation.
