<br />Condition B - Dam is partially or totally failing when condition is <br />discovered; failure of dam cannot be prevented. (Overtopping, sudden <br />increase in seepage, serious earthquake damage, large downstream slope <br />slides, serious piping). <br />1. Make immediate inspection and establish communication. <br />2. Notify authorities: Disaster Emergency Services <br />El Paso County Sheriff <br />Colorado State Highway Patrol <br />Green Mountain Police Department <br />Manitou Springs Police Department <br />Colorado Springs Police Department <br />3. Advise radio, television and press media. <br />4. Warn downstream residents. <br />5. Evacuate and rescue. <br />6. Take action on upstream and downstream dams and control structures. <br />7. Advise regional office (Colorado State Engineer-Denver, Colorado <br />Water Division Engineer-Pueblo). <br /> <br />Condition C - Dam shows signs of rapidly developing failure such as piping, <br />seepage wi th turbidi ty, very much reduced freebOard, serious erosion <br />,jownstream, and slope slides, Time may be available for action to save the <br />dam, such as reducing the reservoir level by opening outlets and gated <br />spillways, lowering spillway crest, using pumps or siphons, sandbagging <br />crest, and blanketing seepage areas. <br />1. Make immediate inspection and establish communications. <br />2. Notify authorities: Disaster Emergency Services <br />El Paso County Sheriff <br />Colorado State Highway Patrol <br />Green Mountain Police Department <br />Manitou Springs Police Department <br />Colorado Springs Police Department <br />3. Advise radio, television and press media. <br />4. Warn downstream residents, <br />5. Evacuate and rescue, <br />6. Take action on upstream and downstream dams and control structures. <br />7. Advise regional office. (Colorado State Engineer-Denver, Colorado <br />Water Division Engineer-Pueblo) <br /> <br />Condition D - Dam shows evidence of a slowly developing failure (slow <br />increase in volume of seepage and turbidity, appearance of sand boils, slope <br />cracking, transverse cracks in embankment crest). Time should be available <br />to lower reservoir level and get equiplllent to site for further action. <br />1. Make immediate inspeotion and establish communications. <br />2. Advise regional offioe. (Colorado State Engineer-Denver, Colorado <br />Water Division Engineer-Pueblo) <br />3. Take action on dam and upstream and downstream control structures. <br />4. Advise authorities, media and others as situation warrants. <br /> <br />:3. Floodproof ing <br /> <br />Currently, the most effeotive type of floodproofing evident in Manitou <br />Springs is that of elevation out of the floodplain. The elevation and <br />setback measures were incorporated into the design of historic structures <br /> <br />-24- <br />
