1) Site should support construction using accepted sustainable trail guidelines; sideslopes should be between 20% and 60%. Shallower slopes will require more manipulation and imported materials to sustainably create the descending grades, undulation, and necessary feature anchoring desired for Flow Country. Steeper slopes are discouraged due to the consequences incurred by users who accidentally leave the trail tread in these more extreme environments.
2) Since maintainable tread and durable features both depend on it, sites with clay-based soils are preferred.
3) The overall trail corridor should incorporate accepted sustainable trail guidelines; a rolling contour alignment, overall grades for long sections should be under 10%, and regular insertion of drainage features (*note Flow Country features/feature-sequences often provide drainage as well).
4) The minimum length of the trail shall be 500 meters in urban environments and a minimum of 1,000 meters in other areas. There is no maximum length.
5) Naturally occurring obstacles are desired. Rocks and forest canopy/elements are valuable for their anchoring qualities and as tread/feature materials as well. A feature-based trail such as Flow Country Trail has a better sense of place when it passes through a landscape with naturally occurring elements.
