water is the enemy
Water is the Enemy

High volume and high velocity water must be taken into consideration in trail design

Where other areas can get by with 10% grade, desert trails should aim for no more than 5-7%

soils are less stable
Soils are Less Stable
  • Sandy and rocky
  • Little clay
  • No organic binders
  • Low shear strength
design for safety
Design For Safety
  • Calming devices
  • Sight Lines
  • Appropriate Width
protect resources
Protect Resources
  • Habitat
  • Historical/Cultural
  • Trails that meet needs
give em what they want
Give ‘em What They Want!
  • Viewpoints
  • Loops
  • Places of interest

Or they will go there anyway!

make it fun
Make it Fun!
  • Contours, turns and dips
  • Variety is the spice of trails
be consistent
Be Consistent
  • Sudden changes = bad
  • Sudden changes without warning = very bad
safety first
Safety First
  • Calming devices can be fun
  • Open sight lines
  • Wide at beginning
  • Wide on steep side slopes
crossing drainages
Crossing Drainages
  • Check dams above and below
  • Contour into large drainages
  • Cross at a right angle
crossing large drainages
Crossing Large Drainages
  • Build up with crib walls
  • Direct flow to middle
  • Downstream side higher
  • If placed by Nature they work well
  • If placed by man, not so good
  • If necessary, think big
  • If not big, use several rocks to interlock
crib walls
Crib Walls
  • Good when bedrock or big rocks make benching impossible
  • Must be stable; pass the “jump test”
  • The bigger the rocks the better…
  • …But sometimes smaller rocks fit better
crib wall construction
Crib Wall Construction
  • On rocky side hills, let wall be above tread a few inches to hold soil
  • When possible, weather side out
  • Fill big to small
  • When all else fails…
  • Leave an option for stock
  • Find a molar
getting water off
Getting Water Off
  • Rolling grade dip, not so good
  • Grade reversal is best
  • Done properly, knicks work well
  • Why wait? Sometimes you can take the water off before it hits the trail
  • Aggressive is good (5-8%)
  • Ankle roll test
  • Build with a light touch
  • The desert recovers slowly
  • Make a new trail look old
aesthetics tips 1
Aesthetics Tips 1
  • Take clippings out of sight, cut end away from trail
  • Palo Verde branches can be put under another tree, cut end to trunk (1-2)
  • Prune for a natural look
  • No hat racks
  • Rub dirt on fresh cut
aesthetics tips 2
Aesthetics Tips 2
  • Work dirt lengthwise on trail to keep it from spreading downhill from tread
  • Pile dirt in middle, then broadcast (far) or cart away
  • Save rocks with weathered side above trail, place strategically after tread is done
aesthetics tips 3
Aesthetics Tips 3
  • Rocks without weathered surfaces (excavated) should be out of sight
  • If you mine rocks above the trail, cover holes (and slides) with weathered rocks
  • After work is complete, look above and below for any construction debris, cuttings
  • No trail is maintenance-free, but sustainable trails require minimal work
  • Walk completed trail several times to look for potential trouble spots
  • Walk after first significant rain to check performance
