Statutory Authority

  • Americans with Disabilities Act (ADA) of

1990

is a civil rights law that requires equal

access to all individuals

regulates State and Local governments

(title II) and the private sector (title III) regardless of funding

slide-3
SLIDE 3

Federal Requirements

  • FHWA Oversight

–Self Evaluation –Transition Plan –Quarterly Updates

slide-4
SLIDE 4

Self Evaluation

  • GIS Based Inventory of all pedestrian

facilities along state highways

  • Review of all design plans for verification
  • f ADA Compliance
  • Field verification of all projects in

construction for ADA compliance prior to acceptance for maintenance

slide-5
SLIDE 5

How SHA is ensuring compliance

  • Development of

ADA compliance checklist

  • Plan review at major

milestones

  • Review during and

after construction

slide-6

Federal Standards

  • ADA Accessibility

Guidelines (ADAAG)- minimum guidelines developed by the US Access Board

  • DOT and DOJ adopt

and enforce ADAAG

  • Best Practices

beyond ADAAG minimums are encouraged

SLIDE 8

In November 2002, OHD & OOTS developed ADA Design guide lines. These Guidelines were updated in December 2005, and included SHA’s ADA Policy specific to roadway transportation projects.

slide-9
SLIDE 9

SHA’s ADA Policy says…

“SHA shall make the accommodation of persons with disabilities a routine and integral element of its planning, design, construction, operations and maintenance activities for all roadway improvement projects.”

Sidewalks

SHA’s goal for sidewalk construction is to make continuous connections to existing sidewalks, schools, transit stations and bus stops. Sidewalks shall be designed to serve all pedestrians, including those with disabilities. Sidewalks shall be designed to provide a smooth, clear and predictable accessible route. Sudden changes in grade or direction, steep cross slopes, unexpected obstacles, drop-offs, narrow pathways and close traffic are all potential hazards.

Sidewalk Requirements

  • Minimum width is 60”.
  • Minimum width at pinch points is 32”. A design

waiver is needed for anything less then 60”.

  • Maximum cross-slope 48:1 (2%)
  • If requirements are not met then an approved

design waiver must be obtained prior to construction.

Sidewalk Ramps

Legislation requires that a ramp be provided at pedestrian walkways, which are intersected by curbs. In cases where none of these standards are appropriate, the designer is required to provide detailed designs for the special ramps.

On New Roadway Construction

  • The ramps will need to be a true 8.33%

slope or MAX. 15’ long.

  • This came from a DOJ ruling for a housing

project.

  • This is in the latest ADAAG guidelines.

Examples of Ramp Placement

Paired Perpendicular Curb Ramps Diagonal Curb Ramp

slide-26
SLIDE 26

Ramp Location

  • SHA preference is to utilize paired

perpendicular ramps, (two ramps on each corner). Large diagonal ramps tend to mislead pedestrians who are blind.

Detectable Warning Surface

slide-29
SLIDE 29

Detectable Warning Surface

  • When?

– at street crossings and signalized entrances

  • Why?

– to alert pedestrians who are blind or visually impaired to the presence of hazards in the line of travel

slide-30
SLIDE 30
  • 24” minimum depth
  • DWS width = ramp width
  • Skewed applications

shall be no greater than 3” from the back of the curb

  • Color contrast shall be

70% different than the surface it is applied

Key Measurements for Driveway Aprons

  • The maximum cross-slope for a path of travel is

48:1 (2%)

  • Minimum width for a sidewalk on a driveway

apron is 36”. (This would not require a design waiver)

SHA’s ADA Design Waiver Process

slide-46
SLIDE 46

Design Waivers

  • Design Waivers will be given to the

Construction PE by Design Manager at Pre-Construction meeting.

  • A Design Waiver must be requested

and approved for each element that is not in full compliance.

slide-47
SLIDE 47

Design Waivers

  • If a field change is made that negatively

impacts ADA compliance, a design waiver must be requested and approved prior to construction.

  • In the field if full ADA Compliance can

not be achieved the construction PE must notify the design PE to request a design waiver and have it approved prior to construction. (See example)

Maintenance of Accessible Pedestrian Traffic

slide-50
SLIDE 50

2003 MUTCD

  • Section 6D.01 Pedestrian Considerations

The needs and control of all road users (motorists, bicyclists, and pedestrians within the highway, including persons with disabilities) through a temporary traffic control (TTC) zone shall be an essential part of highway construction, utility work, maintenance operations, and management of traffic incidents.

slide-51
SLIDE 51

Maintenance of Accessible Pedestrian Traffic Overview

  • This work shall consist of providing and

maintaining an accessible pedestrian route, to the “maximum extent feasible,” throughout the project’s limits. When an existing pedestrian access route within the public right of way is blocked by construction, alteration, or maintenance activity, an alternate accessible pedestrian route shall be provided.

Accessible Pedestrian Signals (APS)

Accessible Pedestrian Signal – a device that communicates information about pedestrian timing in nonvisual format such as audible tones, verbal messages, and/or vibrating surfaces (MUTCD 2003, Section 4A.02)
