Slide 8:
Ground/ Floor Surfaces 
Loose surface materials: most do not comply unless properly treated (e.g., binders, consolidants, compaction, and grid forms) repeated maintenance often required 
Picture of loose gavel surface material

Slide 9:
Slip Resistance
Slip resistance – minimum level (“coefficient of friction”) not specified 
Standard practices for minimizing slipperiness often suffice
Specify according to likely conditions (e.g. exposure to moisture) 

Slide 10:
Surface Smoothness
Surface smoothness – changes in level 
Avoid rough surfaces composed of cobblestones, Belgian blocks, etc. = difficult or painful to negotiate
Picture of rough cobblestone street surface

Slide 11:
Carpet
1/2” max. pile height (measured to the backing, cushion, or pad) 
Texture: level or textured loop, level cut pile, or level cut/uncut pile 
Firm backing, cushions, pads (avoid cushions/ pads for greater firmness) firm securement, edging  

Slide 12: 
Carpet
Securement/ attachment to prevent rolling or buckling (which makes maneuvering difficult)
Picture of carpet rolling and buckling against wheelchair front caster

Slide 13:
Openings
½” max. in one dimension
Long dimension = perpendicular to travel direction
Picture of grate with the long dimension of openings shown perpendicular to the travel direction

Slide 14:
Changes in Level (§303)
¼” maximum – no treatment
½” maximum – 1:2 max. bevel
> ½” – treatment as ramp/ other means of vertical access

Slide 23:
Turning Space along route
Required at 180 degree turns around narrow obstructions (< 48” long) unless route width at least 42” wide 
Two alternative plan views are shown of an accessible route that has a 180 degree turn about an object less than 48 inches wide.  In one figure, the clear width is 36 inches minimum approaching the turn, 60 inches minimum at the turn, and 36 inches minimum leaving the turn. In the other figure, the clear width is 42 inches minimum approaching the turn, 48 inches minimum at the turn, and 42 inches minimum leaving the turn.

Slide 29:
Size (Confined)
Additional clearance where space confined on 3 sides (and more than half of space depth confined)
Image showing Clear floor space for forward approach 36" wide minimum  because it is obstructed on both sides at least 24 inches; clear floor space for side approach 60" long minimum because it is recessed and obstructed on both sides at least 15 inches

Slide 32:
Knee & Toe Space
Toe space 
Toe space 9" high min. and 6" deep max.

Slide 33:
Knee & Toe Space
Beyond toe space, clearance increases from 9” to 27” min. over 3” span (6:1 slope)
From 9" high toe space, clearance increases to 27" min. over a 3" horizontal space (6:1 slope)

Slide 34:

Slide 50:
Protruding Objects
Protrusion limits apply to all areas of circulation – not limited to accessible routes 
Examples of protruding objects: sconces, drinking fountains, sign (perpendicular to wall)

Slide 51:
Protruding Objects

Protruding Objects
Protrusion limits also apply to objects mounted on posts
