26 DESIGN | PEDESTRIAN RAMPS Pedestrian ramps are a critical element of the accessible sidewalk. The details of the design and construction have a significant impact on their usability. • All new pedestrian ramps, including landing areas, will be concrete and include tactile warning strips. • All slopes will meet ADA/AAB requirements. • All new pedestrian ramps will be designed to: • Minimize ponding • Locate ramps as close to the intersection as possible The best design for pedestrian crossings, particularly on narrow side streets, may be a modified raised crosswalk that: • Allows pedestrians to cross the street without having to ramp down. • Reduces the risk of ponding. • Keeps the crossing more in line with the sidewalk.
