A driveway apron constructed by the City or under the City's direction, involving a vertical change in the abutting land and having an apron of four inches or more, shall be reviewed by the Service Department to determine if the cause of the change is directly attributable to base or road failure. If the defect is found to be caused by base or road failure, the City will repair or replace the apron. If it is found that the defect is not caused by base or road failure, repair of the driveway apron will be the responsibility of the owner of the private property abutting such apron. (Ord. 55-83.
