like big drop offs, narrow bridges or other elements of increased risk. When placing signs, consider where you are. Trails with high use should be well signed. Conversely, a technical trail deep in the backcountry should have far fewer signs. Signs can be an intrusion on a visitors outdoor experience - use them with care.9. Utilize Trail Filters A trail filter, sometimes referred to as a gateway or qualifier, is a high-skill-level, low-consequence obstacle that demonstrates the difficulty of the upcoming trail or trail feature. Examples of a filter are a narrow, handlebar width opening between two trees, a rock garden or a rock step. Place filters at the beginning of each advanced trail and just before technical features. By making the entrances to technical trails and features difficult, you prevent unprepared riders from overstepping their abilities.10. Provide Optional Lines There should always be an easier, alternate route around a technical feature. On advanced trails, the technical trail feature can be located on the main line, with an easier option to the side. On intermediate or beginner routes, technical trail features should be outside the main trail flow, and potentially even disguised from the main trail. Optional lines could potentially be in the same corridor as the main trail: For example, a drop-off could vary in height from one side of the trail to the other.11. Provide Adequate Fall Zones A fall zone is the area adjacent to a technical trail feature that provides a clear landing for a rider who has failed to negotiate the obstacle. Fall zones are located at the bottom of descents, on the outside of corners, and on the side of the trail and obstacles. Consider removing branches, stumps, logs, rocks and other protruding objects that could cause injury. Another option is to add mulch or dirt to further soften a fall zone.12. Follow Construction Guidelines Both natural and man-made additions to trails must be durable, predictable and designed to minimize injuries when trail users fail to negotiate them properly. Consider IMBA's detailed construction advice in the freeriding section of the IMBA website.13. Develop an Inspection and Maintenance Log All trails require consistent inspection and maintenance. Technical trail features should be inspected for durability, predictability and safety. Consistent maintenance logs should be kept to ensure trails and features are being kept up to standard. Different trails require different levels of maintenance, depending on a variety of factors, including climate, volume of use and the number and type of trail features. Wooden structures, like bridges and teeter totters require routine upkeep. You must be committed to their inspection and maintenance.14. Designate a Risk Management Coordinator Recruit an individual who will be responsible for making sure recommended risk management techniques are properly implemented and documented. This person will consolidate all of your safety measures and should work with the land owner to create an emergency management plan. Assign responsibility to an individual who is known for their conscientious behavior and attention to detail - and be sure they are willing to perform the job. Remember that the Risk Management
