Maryland Sidewalk Accessibility Inventory. Maryland.

The statewide accessibility inventory included verifying compliance of all existing pedestrian facilities, including a second phase which assessed newly constructed or reconstructed pedestrian facilities as they are built.

WRA has been at the forefront of pedestrian design for transportation facilities that meet the requirements of the Americans with Disabilities Act (ADA), providing a variety of services for state, county and local agencies. These services included providing ADA training for city staff and contractors; inventorying existing facilities, and inspecting newly constructed facilities, for compliance; preparing design plans/field sketches for construction; and on-site field design for construction by on call contractors. WRA was retained by the Maryland State Highway Administration (SHA) to inventory and assess the Americans with Disabilities Act (ADA) compliance of all existing pedestrian facilities along every state roadway in Maryland. Once all existing facilities were inventoried, WRA began the second phase of the project: assessment of new and/or reconstructed ramps and sidewalks as they are built.

Project Highlights


WRA conducted field inspections using GPS and GIS to create a database of statewide sidewalk features and their compliance with the Americans with Disabilities Act (ADA). Data collection of newly constructed sidewalk features and subsequent updates to statewide database of sidewalk features.


Initially, the compliance/non-compliance of 1,000 miles of sidewalk, 25,000 curb ramps, and 2,600 bus stops was recorded, and recommendations for non-compliant locations were developed. In the second phase, 2,800 ADA field inspections have been performed at over 1,700 construction sites statewide.
