In the US, the Americans with Disabilities Act (ADA) requires a slope of no more than 1:12 for wheelchairs and scooters for business and public use, which works out to 1 foot (305 mm) of ramp for each one inch (25.4 mm) of rise. For example, a 20-inch (510 mm) rise requires a minimum of 20 feet (6.10 m) in length of ramp.
How much is paid for curb and sidewalk repair program? The reimbursement rates are: Homeowners : $15 per linear foot of curb repaired. $20 per linear foot of sidewalk repaired. $950 per ADA ramp.
Certain issues were resolved in federal court. One issue, whether sidewalks were covered by the ADA, was appealed to the 9th Circuit Court of Appeals, which ruled that sidewalks were a "program" under the ADA and must be made accessible to persons with disabilities.

Cross slope is provided to provide a drainage gradient so that water will run off the surface to a drainage system such as a street gutter or ditch.

[citation needed] A lower slope of 4% is commonly used on urban roadways where speeds are lower, and where a steeper slope would raise the outside road edge above adjacent terrain. [5] The equation for the desired radius of a curve, shown below, takes into account the factors of speed and superelevation (e).
