The topography of Addison is typical of northeastern Illinois: it is overwhelmingly flat with only gentle, rolling undulations. The elevation averages around 689 feet above sea level.
The lowest points in the village are found along the banks and floodplains of Salt Creek, where elevation can dip to approximately 660 feet. The highest points, nearing 710 to 720 feet, are located in the slightly elevated residential zones in the western portions of the village. There are no natural mountains, deep canyons, or significant topographical extremes; the landscape has been easily adapted to large-scale industrial and residential development.
