Making Sidewalks Accesible At What Cost?

"Disabled Sacramento residents sued the city in 1999, saying it was failing to comply with the federal Americans with Disabilities Act and must make all sidewalks accessible. The city's attorney fought the case, claiming it was not responsible for the sidewalks and that fixing them would be an undue financial burden... The tentative settlement calls for the city of Sacramento to drop its push to have the U.S. Supreme Court hear the case. In return, the city must dedicate 20 percent of designated transportation funds for the next 30 years to improve sidewalks, crosswalks and curb ramps."
