Foundation (engineering)
A foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures.

Residential development of the mountain's southern foothills has been on the rise for several years, primarily in the form of single-family residences. Construction costs have continued to rise as well, in part because of a bill passed in 2003. Oregon House Bill 3375 required that new construction on slopes of 20 percent or greater with unstable soil undergo increased regulation and an extended approval process. The bill doubled the cost of new foundations to around $20,000 to $30,000, and the cost of retrofitting an existing structure approached $100,000.
