Sloping issues require replacing year old sidewalks
New sidewalks are being replaced on Washington and Madison streets in Washington, only a year after they were installed.
“We’ve had a lot of calls from concerned citizens about the work,” City of Washington engineering tech Keith Henkel. said. “The DOT [Iowa Department of Transportation] installed these sidewalks last year and it came to light that some didn’t meet the ADA act.”
The ADA requirements are very detailed, Henkel said. Some of the issues with the sidewalks were due to the slopes not being at the right amount of degree, he said. They were the running slopes and the cross slopes.
According to the ADA Web site, the running slope of the curb ramp is the slope in the direction that people travel when going up or down the ramp run, such as from west to east. For new construction, the running slope of the ramp run must not exceed 8.33 percent.
The cross slope of the curb ramp is perpendicular to the running slope, the ADA Web site said. It must not exceed 2 percent.
Another issue discovered with slopes dealt with the truncated domes (which are the orange portions at the end of the sidewalk), Henkel said. Those weren’t at the right slope either, so the DOT is also replacing those.
Work is expected to be finished within the week and the DOT is paying for all of it, Henkel said.
