<br />IEma.EIGHT <br /> <br />San Miguel County <br /> <br /> <br />e <br /> <br />There were several smaller streams discussed below that were more seriously affected according <br />to Mr. Mike Homer, San Miguel County, No discharge data from these smaller streams was <br />available, and, therefore, they could not be analyzed. <br /> <br />8.3 EXTENT OF FLOODING <br /> <br />The flood information collected was obtained from CDOT and from Mr. Homer. <br /> <br />8,3,1 Affected Streams and Local Drainage Areas <br /> <br />The streams and rivers that were affected by the August 8th storm event were Bear Creek, Fall <br />Creek, Deep Creek, and the San Miguel River. Mr. Homer relayed that Bear Creek was flowing <br />outside the banks and was eroding County Road 60M. <br /> <br />8.3,2 Inundation Limits <br /> <br />Estimated inundation lists are illustrated in Figure 8,1-2. Approximately 20 miles of roadway <br />were impacted by flooding and showed signs of at least partial inundation. This area includes <br />areas in both the San Miguel River basin and Upper Dolores River watershed. <br /> <br />8.4 FLOOD DAMAGES <br /> <br />e <br /> <br />8.4,1 Public Property Damages <br /> <br />The mud slides caused damage to retaining walls along Highway 145. Mr. Blair Renfro. CDOT <br />Project Engineer, estimated that the total costs for reconstruction of all of the retaining walls (at <br />seven locations) will total approximately $900,000 when completed. <br /> <br />8,4.2 Private Property Damages <br /> <br />Two homes sustained major damage from the floods with several others recelvmg minor <br />damages. Several vehicles were damaged as a result of being swept from Highway 145 as mud <br />and rock slid over the roadway surface. One vehicle was pushed into the riverbed. <br /> <br />Private property costs were estimated to be $400,000 according to a NOAA event record <br />(www.ncdc.noaa.com). <br /> <br />e <br /> <br />8.4.3 Emergency Response, Cleanup, and Repair <br /> <br />No injuries were reported, although rescue workers had to use off,road motorcycles and medical <br />evacuation buggies to rescue a woman in labor across seven mudslides to a waiting ambulance. <br />Other individuals were not in any immediate danger but were required to wait until crews could <br />clear the roadway. <br /> <br />CDOT incurred most of the cost associated with the cleanup efforts. Mr. Jay Carlson of CDOT <br />Region 5 reported that extensive cleanup activities were required as a result of mudslide and <br />rockslide debris deposits on State Highway 145, Highway 145 was closed until cleanup crews <br />from both the County and the State could clear a path for passing motorists.
