This project would be funded <br />primarily through the Colorado Water Conservation Board (CWCB) as part of the FEMA Unmet Needs <br />Program. We understand that the City will be usi1;lg the GIS map layers for hazard identification, <br />planning, mitigation, and providing the public with landslide information. <br /> <br />Purpose and Background <br /> <br />The purpose of this project is to create GIS map layers oflandslide hazards and landslide-susceptible <br />terrain in Colorado Springs (hereafter called the Landslide Hazards Map). This will be an interpretive <br />map derived from a variety of other digital and hardcopy data sources. <br /> <br />The main source of data for this project will be a paired set of I inch = 2,000 foot-scale maps of surficial <br />geology and potential geologic hazards, compiled by C. S. Robinson and Associates (Cochran, 1977). <br />These maps were made for El Paso County as part of House Bill 1041 (1974), which required counties to <br />create regional-scale geologic hazard maps for planning purposes. Currently, the I 041 maps do not <br />receive wide use because they are relatively complicated (i.e., they show many different types of geologic <br />hazards and employ unusual notations) and are inaccurate for city-scale GIS and planning uses that may <br />involve a higher level of location precision. <br /> <br />The Landslide Hazards Map is intended to provide a relatively simple, interpretive map that may be used <br />by the City as an overlay and planning tool, to highlight areas where hazard-specific mitigation studies <br />should be done for new development projects. In addition, it is intended to serve as an information source <br />for planners, emergency managers, developers, real-estate brokers, geoteclmical consultants, homebuyers <br /> <br />1 <br />
