7.6.2 Paved Multi-Use Trails
For corridors with heavy bicyclist and pedestrian use , paved multi-use trails are desirable over unpaved since they minimize accidental tripping and provide better traction for all users . If these trails are connected to an urban environment , street , or other major landmarks , it is preferred that they are paved to provide better long term use and limit future maintenance concerns .
Design Criteria :
• The minimum width for a one-way paved facility is 6 feet . The clearing and grubbing area is approximately 12 feet wide and the selective thinning area is approximately 20 feet ( Figure 7.62.1 ).
• The minimum width for a two-way paved facility is 10 feet . The clearing and grubbing area is approximately 18 feet and the selective thinning area is 30 feet ( Figure 7.62 . 2 ).
• Selective thinning is meant to provide visibility along the trail or pathway corridor .
Mature trees that do not create a site distance hazard should be maintained . Additional selective clearing may be required to provide adequate sight lines and safety for the trail users .
• On trails with heavy pedestrian and bicyclist use , a 12-14 foot wide multi-use trail facility is required . The clearing and grubbing area should be an additional 4 feet each side of the pathway plus additional 5 feet each side of the path for selective thinning area ( Figure 7.62.3 ).
• Multi-use trails must conform to ADA and MUTCD standards .
• The recommended surface for paved facilities shall be concrete or asphalt and should be designed to withstand the loading requirements of emergency and maintenance vehicles . Refer to the City of Arlington Design Criteria Manual for pavement standards ( Figure 7.62.4 ).
• Location maps , directional , mileage , and navigation , and regulatory signage (“ rules
