Horizontal drain systems for landslide correction have historically been installed with varying degrees of success. This variability of success has also been apparent in preconstruction exploration, engineering design, and construction and postconstruction monitoring. The USDA Forest Service, Region 6 (Pacific Northwest Region), has accomplished a number of successful horizontal drain projects in the past 5 years. As a result, a system-and-method approach has been developed, along with several low-cost alternative technology tools, for completing the work. This paper is not intended to be an inclusive discussion of all methods, but rather a summary and guide to the project approach and a supplement to the current body of literature on horizontal drain systems.
