The City of Oshkosh has been divided into areas to cover the entire City in approximately a 10 year cycle to provide a consistent and orderly review of sidewalks, driveway approaches, and wheelchair ramps. 1 5/12/2020 Program Overview Sidewalk Requirements Public entities such as municipal governments and transit agencies are required to construct facilities in accordance with the Americans with Disabilities Act (ADA) standards. These standards apply to all new construction. The ADA also requires public entities that retrofit or reconstruct public facilities to comply with these standards to ensure equal access. These requirements include sidewalks, which must be retrofitted to meet all current standards. Any non-compliant sidewalks must be upgraded to meet current standards.
