Infrastructure, such as roads, buildings, airports, and dams, is built and maintained by use of large quantities of aggregate—sand, gravel, and stone. As urban areas expand, local sources of these resources become inaccessible. Other competitive land uses have a higher value than aggregate resources. For example, gravel cannot be mined from under a subdivision. The failure to plan for the protection and extraction of infrastructure resources often results in increased consumer cost, environmental damage, and an adversarial relationship between the industry and the community.
