Please remember that these trails are private property for the exclusive use of residents and their guests. We strictly enforce property boundaries using cameras. Violations will be reported to the La Plata County Sheriff.
We need your help to keep our trails safe and in good shape. This is especially important in Spring and Fall when the ground freezes and thaws, making the soil soft.
We are upgrading to machine-built trails. These are wider, drier, and last longer.
Excavator building the new Water Tank trail in spring of 2025
The Half Rule: We design trails so they aren’t too steep. This helps water flow off the side naturally instead of running down the path.
Full Bench (Solid Ground): We use an excavator to cut a wide shelf (36+ inches) into the hill. This is called a “full bench.” It means you are walking on solid earth, not loose dirt packed on the edge.
Rolling Dips: Instead of waterbars that can trip you, we use “rolling dips”—gentle dirt mounds that guide water off the trail.
Visual Impact: New trails might look “raw” at first. Please give them a few seasons for the grass to grow back and blend in.
Some of our older trails were built straight up and down the slope — what trail professionals call the “fall line.” These trails follow the same path water takes downhill, and over time they develop serious problems:
Trenching: Foot and hoof traffic compacts the soil, creating a channel that traps water and erodes deeper each year.
Braiding: Hikers and riders walk around the muddy trench, widening the damage and creating multiple parallel paths.
Physical barriers: Lining trails with branches can temporarily keep users on a path, but it doesn’t stop water from digging the trench deeper. A well-designed contour trail removes the need for these barriers entirely by making the correct path the most natural and comfortable one to walk on.
Failed drainage: Because both sides of a fall-line trail sit higher than the tread, water bars and drainage features simply can’t move water off the trail.
The science behind these changes is well-documented. Researchers measure Trail Slope Alignment (TSA) — the angle between a trail and the direction water flows downhill. A trail running straight downhill has a TSA near 0° and erodes rapidly. A contour-aligned trail has a TSA near 90° and sheds water naturally. This principle applies regardless of whether the absolute grade is 1% or 10% — even trails crossing flat meadows with a slight grade will trench and widen over time if they follow the fall line.
Once a reroute is established, the old alignment is closed and allowed to recover. Much of this process is natural — compacted soil loosens over multiple seasons and vegetation fills back in. Drainage is restored and the area is signed or blocked to discourage continued use while it heals.
Trail reroutes addressing erosion, property boundary conflicts, and other sustainability issues will be completed as necessary where an existing trail corridor exists.
