The Magna quadrangle, in the western part of Salt Lake Valley, is expected to experience a significant population increase in the next several decades. As urbanization expands into areas less suited for development, geologic hazards become an increasing concern in the planning, design, and construction of new facilities. This study includes 10 1:24,000-scale GIS-based geologic hazard maps that include liquefaction, surface fault rupture, flood hazard, landslides, rock-fall, indoor radon potential, collapsible soils, expansive soils, shallow bedrock, and shallow groundwater potential. The maps are an aid for general planning to indicate where site-specific studies and geotechnical/geologic-hazard investigations are necessary. The accompanying 73-page report describes the hazards and provides background information on data sources, the nature and distribution of the hazards, and possible hazard-reduction measures.
