h. Width (1) one-way 6' - 8' (2) two-way 14' minimum i. Horizontal clearance (1) one-way 8' (2) two-way 14' J. Vertical clearance 10' - 22' Grades should be limited to a maximum of 25 percent. Short steeper passages can be utilized where adequate "in-run" is provided for those ascending, and adequate visibility is given To those descending. 5. Equestrian Trails Equestrian trails require loading/unloading areas and rest areas with water for watering horses. Trails may be used as equestrian trails or snowmobile trails, and therefore the requirements for grades, width, and clearance should reflect a com- bination use. c. Generally grades for equestrian use should be: (1) maximum of 10 percent for extended distance (2) maximum of 20 to 25 percent for a short distance d. Trail length should vary from 5 miles to 35 miles. e. As with snowmobiling, road crossings and intersections should be avoided or kept at a minimum. f. Trail width (1) one-way 2' - 3' (2) ~wo-way 8' - 10' g. Horizontal clearance (1) one-way 6' - 8' (2) two-way 10' - 12' h. Vertical clearance 10' - 12' i. Trail surfacing should be' natural or wood chips. Biking Trail Standards Suggested references for bike standards are 1) "Bikeways Guide: Model Criteria for Bikeways and Recreational Lanes WiThin the Highway Right-of- Way," November 1974, by Transportation Planning, Minnesota State Planning Agency, 550 Cedar Street, St~ Paul, Minnesota 55101; and/or 2) "Bicycle Trails Manual," by Minnesota Department of Natural Resources, Division of Parks and Recreation, 320 Centennial Building, St. Paul, Minnesota, 55155. Both documents contain design standards for bicycle trail construction The "Bikeways Guide" is more useful for designing bike-lanes on streets and highways~ The "Bicycle Trails Manual" has better information on the design of 'bicycle paths' (treadways that are not part of the street or highway), and on state bicycle grants-in-aid funds. -12-
