The costs of improperly designed trails are hard to measure, but some of the costs are: erosion, labor to address erosion problems, poor user experience, trails that don’t get used, short cutting, possible extra rouge trails, and unnecessary safety risks.
Professional trail contractors usually install trails for +/-$3-7/foot (pre-Covid and inflation), or +/-$30,000/mile if heavy equipment is required. Rocky terrain and prevailing wage requirements can more than double costs. Additional increases can come with trail features like jumps, berms, switchbacks/climbing turns, steps, rock armoring, walls and bridges…
In many cases trails can be installed by volunteer labor, at the cost of a few meals, some water, and a thank you. This will also build community involvement and a sense of ownership. Some projects segregate professional crews from volunteers or the two are joined. Some projects are exclusively volunteers or professionals.
Successful trails:
- have a sense of purpose- destinations, overlooks, rock outcrops, loops etc.
- keep within plan objectives of:
- Systemic: endeavor to be a complete system emphasizing local and regional continuity and connectivity
- Destination-Oriented
- keep within plan objectives of:
- cater to multiple levels of users- beginner to advanced hiker/runner/biker/equestrian
- are sustainable via the use of modern “trail science”- out sloped, sustainable grades, frequent grade reversals, positive and negative control points…(Criteria for trail placement, control points, and layout)
Common mistakes of trail building are:
- Falling for the Fall Line–Put simply, fall line trails are erosion nightmares. They turbo-charge natural and user-created erosion, exposing rocks and roots and generally living short lives before becoming loose, wide, ecosystem-damaging disasters. To build trails that last, use the Half Rule: trail grade, or steepness, shouldn’t exceed half the grade, or steepness, of the hillside; and the 10 Percent Rule: overall trail grade should be 10 percent or less.
- Guessing the Grade–Nobody, no matter how masterful their eye, can guess trail grades right every time. Trust us, we know. Sure, it’s fun to try, but use a clinometer to confirm the grade whenever you’re laying out trail – it’s worth a regiment of self-powered, Fantasia-style Pulaskis, because no amount of trailwork can fix a trail built on an unsustainable grade. If you don’t have a clinometer, we highly recommend an investment in this indispensable tool.
- Going Against the Flow–Not even race courses – which are sometimes designed with erratic flow to throw off a racer’s rhythm – should make this trailbuilding faux pas. All trailbuilders should make “smooth transitions” their mantra. Bad flow, especially fast sections leading into sharp turns, is a primary cause of user conflict. When you are building, think flow – it’s the key to an enjoyable trail.
