When sited, laid out and built well, turns can be the highlight of a trail, providing aesthetics and flow. But they are often sited poorly, laid out wrong, and built without proper attention to grade, drainage and geometry. In this class we'll discuss turns as control points in the design process. We'll lay out switchbacks, and slope grade and entrenched climbing turns. Using basic layout tools, learn how to make your turns beautiful, low-maintenance and FUN.
Understand turn geometry
Use turn locations as control points
Site and lay out turns correctly for construction
Day 1: Half day: Discussion of layout principles & turns, including slides, diagrams, tables, photos, & hands-on exercises.
Day 2: Field Exercises: in small groups, get comfortable with layout tools and how siting turns fits into the design process. Practice laying out and staking turns in a variety of settings. Lots of on-site discussion as well as hands-on instruction for folks at all levels of experience.
Day 3: Half Day: Field Exercises & Assessment
WHAT TO BRING
Appropriate field gear for the weather. Expect to be outside on Day 2 & 3. We are in Colorado in March - please prepare for the unpredictable weather.
