I am genuinely curious, how was SFStL able to get operational approval for a project that included ADA upgrades which were not completed? My knowledge is limited to the traffic engineering world where any work that is done on an existing roadway facility must upgrade it to ADA compliance. I know of specific instances where a City deferred maintenance (a simple asphalt mill and overlay) because the overlay was in the budget, but the cost of all of the necessary ADA ramp upgrades for the sidewalks at every intersection was too much.
