Whenever a permit is issued to construct, reconstruct, repair, alter or grade any sidewalk curb, curb cut, driveway or street, handicapped ramps shall be required to be installed in accordance with design standards included in the city's standard plan and specifications at all curb and driveway crossings to be constructed, reconstructed, repaired or altered; provided, that the director of public works may waive said requirement if he determines that requirement of handicapped ramps is impractical under all the circumstances.
