How Many Ramps Must Be Redone?

Lancaster City is fighting an uphill battle.

A year after facing a lawsuit filed by three residents with disabilities over the city's failure to install wheelchair ramps at intersection sidewalks, city officials now must go back and rebuild the ramps it has already installed.

Over the next eight to 10 weeks, city public works crews will be evaluating each of the nearly 1,700 curb ramps that have been installed in recent years to see if they comply with the current regulations of the federal Americans with Disabilities Act.

Those ramps did comply with federal regulations when they were installed, said Public Works Director Charlotte Katzenmoyer, but the law has been changed and so have the regulations.

Unlike other laws, in which existing situations are accepted or "grandfathered," the revisions to the 1992 ADA law require ramps to be updated to the current regulations, she said.
