§ 82.19.050 Development Standards for Trails.

   The following standards shall be used to evaluate proposed trails:

Table 82-23
Urban Standards (Maximum Accessibility)
Item	Bicycle+ Pedestrian (1)	Bicycle- only (1)	Hiking- only	Equestrian- only (4)
Minimum width (one way)	10 ft.	5 ft.	5 ft.	8 ft.
Minimum width (two way)	12 ft.	8 - 10 ft.	8 - 10 ft.	10 ft.
Surface	Hardened, e.g. asphalt(2)	Hardened, e.g. asphalt	Hardened	Hard-packed, No paving
Shoulder	2 ft. minimum	2 ft. minimum	2 ft. minimum	2 ft. minimum
Vertical Clearance	12 ft.	10 ft.	10 ft.	12 ft.
Cross Slope	2 percent maximum	2 percent maximum	2 percent maximum	2 percent maximum
Maximum Grade	5 percent	5 percent	5 percent	Maximum limit is erosion control

 

Table 82-24
Low Use and Natural Area Standards
Item	Bicycle+ Pedestrian (1)	Bicycle- only (1)	Hiking- only	Equestrian- only (4)
Minimum width (one way)	6 - 8 ft.	2 ft.	2 ft.	6 ft.
Minimum width (two way)	8 - 10 ft.	2 ft.	4 ft.	8 ft.
Surface	Firm all weather and unobstructed	Minimize erosion	Minimize erosion	Minimize erosion
Shoulder	2 ft. minimum	2 ft. minimum	2 ft. minimum	2 ft. minimum
Vertical Clearance	10 ft.	8 ft.	8 ft.	12 ft.
Cross Slope	3 percent maximum	3 percent maximum	3 percent maximum	3 percent maximum
Maximum Grade	5 percent; rest and turning areas every 200 ft. minimum	Maximum limit is erosion control	Maximum limit is erosion control	Maximum limit is erosion control
Notes:
(1)   Standards meet Caltrans Class I Bikeway standards.
(2)   Where equestrian uses occur, an appropriate trail material (e.g., decomposed granite) shall be provided on the equestrian portion of the trail only; the remainder of the trail shall use materials appropriate to its intended use.
(3)   Multiple use trails with both bicyclists and equestrians shall be no narrower than six feet. A combined use trail with hiking and bicycling only should be no narrower than four feet.
(4)   A maximum of 20 percent vertical grade or as needed for erosion control, whichever is less. This can be exceeded for short distances (no more than 200 feet).
