The 1999 Colorado Springs, Colorado Landslides – Federal, State and Local Government Response; Public Involvement; and Future Long-term Risks and Challenges
June 18-21, 2006
In the spring of 1999, heavy rain precipitated landslides in over 12 developed areas in Colorado Springs. The landslide damage and destruction exceeded $80 million dollars. A combined federal, state and local response included active participation by property owners in an open and transparent public process. The resulting federally funded mitigation project was a success, but this can only be considered an interim objective for an inherent serious local problem. Colorado Springs is normally an arid environment but high moisture years, like 1999, can result in activation of new landslides and reactivation of existing landslides. Residential neighborhoods continue to expand and encroach in areas where a combination of topography and the underlying Pierre Shale present significant long-term stability challenges.
