These construction techniques apply to all types of trails. Refer to the specific trail design guidelines for different types of trails to decide what is appropriate in each setting.

• Use design details and construction materials that are simple, functional, and complement the setting.
• Use on-site or locally available materials in park wilderness zones. Limit the use of dimension lumber, concrete, asphalt or other imported construction materials to more intensively used management zones.
• Select materials and construction techniques that blend into the natural setting. Avoid chemical preservative treatments of finishes where possible.
• Minimize changes to the existing site conditions.
• Select design details and construction materials that will reduce long term maintenance. For example, drainage dips require less maintenance than culverts.
• Conduct a job/project safety analysis prior to starting construction.
