Description: This dataset is part of data presented in Colorado Geological Survey Map Series 42 publication. The publication show areas of landslide susceptibility and outlines of landslides mapped within the city limits of Colorado Springs. This map is not intended for site-specific determinations of ground stability or assigning risk, nor does it imply that any property that lies within zone boundaries is necessarily currently unstable. The intent is to provide map coverages that will aid ongoing city planning, allow for general-public information disclosure and education, and prompt a future level of geological and geotechnical investigation that is appropriate for the hazards and potential risks present. The project methodology applied a modified heuristic or qualitative method using a basic inventory of landslides, published and non-published geologic maps of the area, known engineering characteristics of bedrock and derived soils, and digital information, both image-based and calculated from precise photogrammetry (Soeters and van Western, 1996). Previous landslide susceptibility studies and projects (Ahmad and McCalpin, 1999; Wegmann and Walsh, 2001) and earlier Colorado Springs-specific land use/zoning and hazard reports and maps (Hill, 1974; Gruntfest and Huber, 1985) were reviewed for this project. Other data were derived from various consultant reports, GIS data sources, aerial photo interpretations, and field checking by CGS engineering geologists. Certain forms of ground movements were not included in the scope of this project. They include: slow, shallow creep; ground subsidence from collapsible soils or mine subsidence; swelling and heaving from expansive soil and bedrock; and rapid forms of mass movements such as rockfalls, rock-slides, and debris flows. These types of geologic hazards, while still significant in Colorado Springs, are not included or mapped for this specific publication.
