Flood Mitigation & Land Rehabilitation

Purpose

With increased potential for flooding, debris flows and weed invasion in the Fourmile Canyon Fire area due to loss of vegetation and bare slopes, the Boulder County Fire Rehabilitation Implementation Team undertook a series of watershed-level treatments in 2011 and 2012 aimed at reducing erosion and weeds in the areas hardest hit by the fire.

Resources for Private Landowners:

  • Land Rehabilitation FAQ Guide. Landowners should continue to consult this list of frequently asked questions for information about what you can do on your own land to help it recover from the fire.

    • Land Rehabilitation FAQ Supplement II. Information for landowners to consider during the second summer post-fire (2012).

    • Land Rehabilitation FAQ Supplement I. A list of frequently asked questions about bark beetle management in the burned area

  • Call the Natural Resources Conservation Service (NRCS) at 303-776-4034 ext. 3 for seeding and soil stabilization recommendations, and for individual consultations about your land.

  • Homeowner’s Sandbag/Erosion Control Guide for Flood, Debris, and Erosion Control. Includes tips on how to properly use sandbags.

  • List of forestry contractors (provided by the Colorado State Forest Service-Boulder District) for help in undertaking work on your land.

Private landowners are encouraged to use the resources identified above to protect private land from post-fire degradation and to protect the community against loss of life, property, and shared resources on a watershed level.

Land Rehabilitation, Stabilization and Watershed Protection

April 2011 photo of helicopter picking up straw for aerial mulching in Four Mile CanyonLand damaged by high intensity fires cannot retain rainfall and runoff as unburned vegetated areas do, leading to surface water runoff and debris flows that would not occur during normal rain events in areas where trees and ground cover are present.

Federally and state-funded seeding and aerial mulching treatments aimed at preventing soil erosion, decreasing flooding impacts, and preventing weed invasions as a result of the wildfire took place in March and April in the Four Mile, Gold Hill, Sugar Loaf and Sunshine Canyon areas.

Flood Awareness and Emergency Preparedness

There is increased potential for flooding and debris flows in the Fourmile Canyon Fire area due to loss of vegetation and bare slopes. Anyone living in or traveling through the area should be aware of the increased risks.

Be prepared to take action in advance of any potential flooding or debris flows.

Our Mountain Communities Preparedness Guide gives recommendations on how to make the best decisions possible in the event of a flood. For further assistance in emergency planning, contact the Boulder Office of Emergency Management at 303-441-3390.

More About Land Rehabilitation

An environmental assessment was done to determine post-wildfire threats to soils, vegetation, hydrologic functions such as debris flow in drainages and slopes, trees, transportation infrastructure, abandoned mines, cultural resources, and wildlife.

The analysis determined that an increased threat of flooding and debris flows to homes and infrastructure exists, particularly along the Gold Run Creek and Fourmile Creek watersheds.

It also provides recommendations for treatments that will reduce these risks or threats. See maps of burn area damage and recommended treatments.
