Flood Information
What to do in a flood
  • A community hotline – 385-8700 – would be activated in the event of a serious flooding emergency. This hotline helps divert calls away from 911 to prevent blocking the line.
  • For emergency floodassistance in La Plata County, call 911 or the local chapter of the American Red Cross at 259-5383, 24 hours a day. The Red Cross is also offering free access to shovels, hoses and other ash- and mud-flow clean-up equipment. Call the Red Cross line if you would like to be added to a volunteer list to help with flood clean-up.
Building with erosion in mind

What can be done to avoid or reduce the hazard of debris flow?
To be safe, assume that all drainages in steep, hilly areas are capable of carrying debris flows and are especially vulnerable after a wildfire.

  • Avoid building sites at the bottoms and mouths of steep ravines and drainage courses.
    These areas are most likely to be inundated. The outer banks of bends along such ravines should also be avoided, because swiftly flowing debris avalanches can “ride up” out of the bottom of the stream channel where it bends.
  • Avoid building on or below steep slopes.
    In general, the steeper the slope, the greater the risk. If these areas must be used, consult with a soils engineer and engineering geologist. They will be able to evaluate the potential for problems and give advice on the best way to minimize the risk to life and property.
  • Limit the height and slope of cuts and fills in human-modified slope cuts.
    Properly compact fills and key them into bedrock to properly control the flow of water onto slopes.

Post-fire rehabilitation treatments

1. Stabilize soils and steep slopes: Runoff may increase after fire due to water-repellency in soils and lack of vegetation to absorb and use rainfall. Possible treatments are:

  • Plant grass seed
  • Mulch
  • Use cross-slope log erosion barriers

2. Maintain stream channel conductivity: Channels become plugged from debris torrents following rains on burned areas. Runoff then flows overland or cuts new channels, causing more erosion. Possible treatments are:

  • Frequently check and clean out culverts
  • Remove excessive amounts of debris from channel areas, leaving some for in-stream stability
  • Install temporary check structures in ephemeral drainages

3. Revegetate/reforest burned areas: Loss of vegetation leaves land vulnerable to increased runoff, erosion and sedimentation; encourages weeds; degrades habitat; and impairs forest regeneration. Possible treatments are

  • Plant grass seed
  • Plant forest trees
  • Use buffer plants along stream corridors

  • Know what to expect
  • If it has been raining hard for several hours, or steadily raining for several days, be alert to the possibility of a flood.
  • Listen to local radio or TV stations for flood information. Reduce risk of damage
  • Raise your furnace, water heater, and electric panel if they are in areas of your home that may be flooded.
  • Consult with a professional for further information if this and other damage reduction measures can be taken. Watch vs. Warning n Flash floods can take only a few minutes to a few hours to develop.
  • A flash flood watch means flash flooding is possible in your area. n A flash flood warning means a flash flood is occurring or will occur very soon. Prepare a disaster plan
  • Check to see if you have insurance that covers flooding. If not, find out how to get flood insurance.
  • Keep insurance policies, documents, and other valuables in a safe-deposit box. Assemble a disaster supplies kit n First aid kit and essential medications.
  • Canned food and can opener. n At least three gallons of water per person n Protective clothing, rainwear, and bedding or sleeping bags. n Battery-powered radio, flashlight, and extra batteries.
  • Special items for infants, elderly, or disabled family members.
  • Written instructions for how to turn off electricity, gas and water if authorities advise you to do so. (Remember, you’ll need a professional to turn them back on.)
  • Identify where you could go if told to evacuate. Choose several places . . . a friend’s home in another town, a motel, or a shelter. When a Flood WATCH Is Issued
  • Move your furniture and valuables to higher floors of your home.
  • Fill your car’s gas tank, in case an evacuation notice is issued. When a Flood WARNING Is Issued n Listen to local radio and TV stations for information and advice. If told to evacuate, do so as soon as possible. When a Flash Flood WATCH Is Issued . . .
  • Be alert to signs of flash flooding and be ready to evacuate on a moment’s notice. When a Flash Flood WARNING Is Issued . . .
  • Or if you think it has already started, evacuate immediately. You may have only seconds to escape. Act quickly!
  • Move to higher ground away from rivers, streams, creeks, and storm drains. Do not drive around barricades . . . they are there for your safety.
  • If driving, be aware that the road bed may not be intact under flood waters. Turn around and go another way. NEVER drive through flooded roadways.
  • If the vehicle stalls, leave it immediately and seek higher ground. Rapidly rising water may engulf your vehicle and and sweep you away.
  • Be especially cautious at night when it is harder to recognize flood dangers.
  • Do not camp or park your vehicle along streams and washes, particularly during threatening conditions.

Erosion-control methods
Method
What does it do?
When should you use it?
Jute Netting
A netting made of jute can be laid and anchored over straw or other mulch to protect it from wind and water damage. It may be applied as an alternative to straw or wood mulches on flat sites for dust control and seed-germination enhancement. Don’t use it alone in high-runoff areas.
Sandbags
An inexpensive temporary barrier or wall, 1 to 2 feet high, can be constructed by stacking sand- or earth-filled bags. Use it to protect building sites vulnerable
to low mud debris flows from steep slopes that are void of vegetation. It will not provide protection from high debris flow.
Silt fence
A fence made of woven wire and fabric filter cloth is a temporary barrier that can catch sediment-laden runoff from small areas of disturbed soil. Major considerations for use of silt
fences are slope, slope length, and the amount of drainage area from which
the fence will catch runoff.
Straw bale check dams
Temporary sediment barriers are
constructed of straw bales located
across small drainages.
Use them to slow debris flows in small channels. They are not intended to provide protection from large storms or control debris flows in creeks, streams or rivers.
Straw mulching
Straw mulch forms a loose layer when applied over a loose soil surface. It
provides a protective cover to reduce
erosion and aid in revegetation.
Straw should be used on slopes that have been seeded and have a high potential for erosion. It requires some type of anchoring to prevent blowing or washing away.
Contour tree felling
It reduces the amount of rain water
that runs down a slope by cutting trees
so they fall perpendicular to the main direction of the slope.
Use it on burned slopes where there
are a number of dead trees that have
little value. Workers must be alert to the danger of falling trees and branches.
