I live in one of the most flattest places in the us and even that has some unevenness that allows creeks and rivers to flow. I wish I could use topo maps to show it as they have countour lines with the elevation on every 5th contour and the spaces tween the lines is set up to give you a good idea and they also have bench mark. we have had depressions. the sand ridge which is natural and goes back before the rr(1890's) is natural and its the reason why the rr is where it is. to allow water to run off the rr and also to have good footing for the tracks. the highest point in my county per the topo isn't even 50ft above sea level. that is the 1949 topoSome pretty obvious elevation differences going on there.
I don't think that can be described as flat, even, smooth and level.
