I I I I I I I I I I I I I I I I I I I Flooded Area Description Since Mitchell Creek did not overtop it's banks and flood during this event, few areas sustained damage due to floodwater. Any damage sustained was due to several mudslides that occurred throughout the region. Areas of the city, and nearby area, that were inundated with mud, water, and debris include: Mitchell Creek Road, West Midland Avenue, parts of Ami's Acres campground, part ofthe railroad tracks in South Canyon, "a channel that was set up between Two Rivers Chevrolet and Glenwood Springs Ford..." (Daniels, 2), and several residential driveways and yards. Estimated Flood Damal!es & Anv Special Factors Affectinl! the Flood Since the studied event was minor in origin (less than a 2-year event) with no rivers or streams flooding, damage to infrastructure and personal property was limited to erosion and a lot of mud clean-up work. Mudslide damage included several roads around the Glenwood Springs area Mitchell Creek Road, and West Midland Avenue, were all closed for varying amounts of time as cleanup work was done. Mitchell Creek Road got the worst of the mud and was closed to nonresidents for days as the mud and debris were removed with construction equipment. Mitchell Creek sustained mud damage as wel~ and work had to be done to clear out the debris and mud from the creek bottom in preparation for future storm events. Vacious residents had mud covering their driveways and yards and some minor erosion damage was reported. Luckily, no injuries or casualties were reported from this event. During the evacuation, several people became trapped in their cars by the powerful mudflows but were freed by rescue workers and other residents. Damage estimates were obtained through Mr. Denney with the Office of Emergency Management. It cost $10,370 to clean-up Mitchell Creek and remove the mud from nearby Mitchell Creek Road. Pictures ofthe damage to the road and the creek are included in the Additional Support Information section of this report, courtesy of Mr. Denney. Cleanup damage for the rest of the city was estimated at $8,795, but at the time of this study, it was unknown ifthese were the final damage figures. According to Mr. Denney, and an article in the Glenwood Springs Post Independent by Heather McGregor, several mitigation efforts had been underway before the storm hit on the 5th of August. An effort to clean out the creek and contain overflowing water and mudflows along the creek's drainage path was completed costing an estimated $130,000. The project used "Jersey Barriers" and sand bags to contain any large debris during a flood event. This project was a small piece of a large federal project by BAERT designed to mitigate the damage done by the Coal Seam Fire. Mr. Denney provided some pictures ICON Engineering, Inc 44 January 2003
