NYSDOT Designers Toolbox ADAAG and proposed guidelines State and Local Codes and Guidelines Standard Details Access Board Advice Good Professional Judgment (Common Sense)
Sidewalk Widths Previously required 3 feet Minimum for travel 4 feet Preferred for Travel 5 feet (NYSDOT Standard Width) Additional space for turning and opening doors Accessible Route
Clearances and Obstructions Accessible Route
Cross Slope No steeper than 1 on 50 (2%)
Excessive Cross Slope
Excessive Cross Slope
Instability on Compound Slopes
Counter Slopes Street 5% Ramp 8.33%
Vertical Changes Maximum vertical change ¼ Maximum longitudinal gaps ½ Maximum gap at railroad 2 ½ Accessible Route
Surfaces.stable, firm and slip resistant. (ADAAG) NOTE: Smooth surfaces are preferred by many disabled people. Accessible Route
Stable, Firm and Slip Resistant Surfaces Acceptable Surfaces Broomed concrete Asphalt Compacted earth or gravel Stabilized soil (consolidantes and grid forms) Pavers Unacceptable Surfaces Gravel and sand Woodchips Smoothly Troweled Concrete Accessible Route

Curb Ramps. What not to do!
Driveways. What not to do! Maintain 2% crossslope across driveways. Driveways
Wide Sidewalk or Setback Driveways - Note: Use 4 foot minimum walkway width.
Narrow Sidewalk with No Setback Driveways Note: Use 4 foot minimum walkway width.
Driveway with Wide Sidewalk Driveways
Ramped Driveway Driveways - Note the 2% cross-slope on driveway apron.
Driveways Apron Offset Sidewalk
Detectable Warnings (Tactile Surface) Required on curb ramps by ADAAG in 1990 Requirement suspended by U.S. DOJ in 1994 Suspension has run out and detectable warnings are required Sidewalk/Street Transitions
Detectable Warnings (Tactile Surface) 0.9 (23mm) diameter at base 2.35 (60mm) spacing O.2 (5mm) high Aligned perpendicular to travel Contrasting color
Detectable Warning at Cut Through
NYSDOT Approved Colors Federal Color #14062 -Green - Munsell 2.5G 3/6 Federal Color #30108 - Brown - Munsell 10YR 3/2 Federal Color #31136 -Red - Munsell 10R 3/6 Federal Color #37031 -Grey - Munsell 10BG 3/1
Tiles and sheet goods
Bricks or pavers
Detectable Warnings at Sidewalk Street Transitions 24 in direction of pedestrian travel Set back 6 to 8 from curb face (line) Full width of curb ramp Limited range of truncated dome spacing and diameter Orient domes in direction of predominant pedestrian travel High visual contrast Sidewalk/Street Transitions
What s New What s Expected? Draft Guidelines Minimum accessible width - 48 w/o exceptions Grade of sidewalk same as adjoining street Check www.access-board.gov for updates about the forthcoming Public Right-of-Way Accessibility Guidelines. (Presently out in draft, Final due Fall 09)
What s New What s Expected? Draft Guidelines Max. ramp elevation change 5 feet (??) Pedestrian signals at slip lanes and roundabouts (??) Audible and vibrating indications on all pedestrian signals Contrasting color on stair noses At least one accessible parking space on every block
