The Build Greater Austin Program in Austin, TX has dedicated $3.6m to sidewalk installation, prioritizing improvements along transit routes. An accessibility advisory group identifies locations needing curb ramps, maintenance, barrier removal, and other spot improvements for pedestrians with disabilities.

“To promote both efficiency and accessibility, public entities may choose to construct curb ramps at every point where a pedestrian walkway intersects a curb. However, public entities are not necessarily required to construct a curb ramp at every such intersection.”
--DOJ Title II Technical Assistance Manual

“Alternative routes that make use of existing curb cuts may be acceptable under the concept of program accessibility in limited circumstances where individuals with disabilities need only travel a marginally longer route. In addition, the fundamental alterations and undue burdens limitations may limit the number of curb ramps required.”

The San Francisco Department of Public Works has established a 5-point ranking system to identify and prioritize curb ramp installation. Of highest priority are locations with existing ramps that are deemed unsafe. Ranking second are locations where no curb ramp currently exists at a pedestrian crossing. A third category will add a curb ramp at a location where only one crossing direction currently has a curb ramp. Priority four includes substandard curb ramps that do not fully comply with standards but are considered safe to use. Of lowest priority are severely-constrained locations where curb ramp installation alone would be prohibitively expensive and require substantial reconstruction.
