6 Key Federal Actions and Guidelines Who is affected Design elements Sidewalks Surfaces Curb ramps Driveways Detectable warnings

7 Key Federal Actions U.S. Architectural and Transportation Barriers Compliance Board (Access Board) Americans with Disabilities Act (ADA) of 1990 Civil Rights Act Enforced By the U.S.Justice Act American With Disabilities Act Accessibility Guidelines (ADAAG) 1991 Preliminary Draft Public Right-of-Way Guidelines

8 Guidelines for Public Rights-of-Way Proposed ADAAG Public Right-of-Way Section Access Board Interim Final Rule Public Awareness Campaign aimed at the Transportation Industry Rights-of-Way Advisory Committee Access Board Draft Guidelines June, 2002 Next Step Federal Rulemaking

9 Primary Subjects of Our Design

10 Design issues for pedestrians who use wheelchairs

11 U.S. Access Board Independent Federal Agency

12 NYSDOT Designers Toolbox ADAAG and proposed guidelines State and Local Codes and Guidelines Standard Details Access Board Advice Good Professional Judgment (Common Sense)

13 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

14 Clearances and Obstructions Accessible Route

15 Cross Slope No steeper than 1 on 50 (2%)

16 Excessive Cross Slope

17 Excessive Cross Slope

18 Instability on Compound Slopes

19 Counter Slopes Street 5% Ramp 8.33%

20 Vertical Changes Maximum vertical change ¼ Maximum longitudinal gaps ½ Maximum gap at railroad 2 ½ Accessible Route

21 Surfaces.stable, firm and slip resistant. (ADAAG) NOTE: Smooth surfaces are preferred by many disabled people. Accessible Route

22 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

23 Curb Ramp Types Perpendicular Ramp (Curb Ramp) Parallel Ramp (Transition Ramp) Combination Ramps (Assemblies) Corner Parallel Ramp (Shared Flush Landings) Sidewalk/Street Transitions

29 HANDICAP SIDEWALK RAMP STANDARD SHEETS

30 Perpendicular Approach Sidewalk/Street Transitions

31 Perpendicular Ramp Curb Ramp

32 Perpendicular Ramp Sidewalk/Street Transitions

33 Parallel Ramp (Transition Ramp) Detectable Warning Sidewalk/Street Transitions

34 Parallel Ramp Sidewalk/Street Transitions

35 Combination Ramp (Assemblies) Detectable Warning Sidewalk/Street Transitions

36 Combination Ramp (Assemblies) Sidewalk/Street Transitions Detectable Warning

37 Corner Parallel Ramp (Shared Flush Landing) Sidewalk/Street Transitions

38

39 Level landing Large Corner Radius

40 Diagonal Ramp (Shared Curb Ramp) Justified only when there are site distance issues, ROW constraints, or other limiting factors that must be address. Must be documented in the Design File and/or Record Plans. Sidewalk/Street Transitions

41 Curb Ramps. What not to do!

42 Driveways. What not to do! Maintain 2% crossslope across driveways. Driveways

43 Wide Sidewalk or Setback Driveways - Note: Use 4 foot minimum walkway width.

44 Narrow Sidewalk with No Setback Driveways Note: Use 4 foot minimum walkway width.

45 Driveway with Wide Sidewalk Driveways

46 Ramped Driveway Driveways - Note the 2% cross-slope on driveway apron.

47 Driveways Apron Offset Sidewalk

48 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

49 Detectable Warnings (Tactile Surface) 0.9 (23mm) diameter at base 2.35 (60mm) spacing O.2 (5mm) high Aligned perpendicular to travel Contrasting color

50 Detectable Warning at Cut Through

51 NYSDOT Approved Colors Federal Color # Green - Munsell 2.5G 3/6 Federal Color # Brown - Munsell 10YR 3/2 Federal Color # Red - Munsell 10R 3/6 Federal Color # Grey - Munsell 10BG 3/1

52 Tiles and sheet goods

53 Bricks or pavers

54 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

55 What s New What s Expected? Draft Guidelines Minimum accessible width - 48 w/o exceptions Grade of sidewalk same as adjoining street Check for updates about the forthcoming Public Right-of-Way Accessibility Guidelines. (Presently out in draft, Final due Fall 09)

56 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
