Estimated Flood Dama2es & Anv Special Factors

Affectin2 the Flood

Since the studied event was minor in origin (less than lO-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.

All three mud-covered county roads sustained erosion and clean-up damage. County
Road 306 had the most severe damage from the storm. Pictures of the CR 306 mudslide
damage, and trapped cars, are shown in the Additional Support Information section of
this report. According to Mr. Carl Hasselbrink with Chaffee County, this route was
closed for approximately ten days for repairs. The guardrail was replaced in places and
patchwork was done to the road, as well as the nearby hillside, due to erosion. The total
cost associated with these damages, was $76,835.

Minor injuries, most involving mild hypothermia, were reported for the event. No
casualties were reported.
