An emergency was determined for water quality degradation. The
probability of loss is Very likely and the magnitude of
consequence is Major. Therefore, the risk is Very High.
Flood Hazard
The flood hazard is predicted to increase dramatically within and immediately downstream of the
burn area. An emergency for flood hazard was determined for the following reasons:
• Runoff is predicted to increase significantly following the fire.
• There are a high number of residents and recreationists in the area resulting in high
numbers of people exposed.
• High traffic roads with drainage structures including Colorado Highway 14 and County
Roads 27, 52E, 25E, 44H and 63E.
• There is substantial risk to life and property resulting from the increased flood risk.
The probability of loss is Very likely and the magnitude of
consequence is Major. Therefore, the risk is Very High.
Debris Flow Hazard
The debris flow hazard is expected to increase significantly in the years following the fire. An
emergency for debris flows was determined for the following reasons:
• There are a high number residents and recreationists in the area resulting in high
numbers of people exposed.
• The infrastructure in the area in not adequate to handle the increases in flow and
sediment predicted.
• Debris across the roads in the area could result in large numbers of people being cut off
from emergency services, possibly for long periods of time.
• There is substantial risk to life and property resulting from the increased debris flow risk.
The probability of loss is Very likely and the magnitude of
consequence is Major. Therefore, the risk is Very High.
Road Washout Hazard
The road wash out hazard is expected to increase significantly in the near future. An emergency
for roads washing out was determined for the following reasons:
• There is substantial risk to life and property resulting from the increased debris flow risk.
• The current transportation system is not expected to handle the predicted flood flow
increases and sediment loads.
• Roads washing out in the area could result in large numbers of people being cut off from
emergency services, possibly for long periods of time.
The probability of loss is Very likely and the magnitude of
consequence is Major. Therefore, the risk is Very High.
