Not really, most of Lincoln is well above even the 500 year flood plains, and we're pretty much at the high point of our neighborhood, so it'd take a flood of Biblical proportions to affect us. We have, on one occasion, had a little water come in by the walk-out basement door, but that was after something like 12 inches of rain in 3 days and we've done some re-grading of the yard since then and redone the master deck so that it is less likely to direct water towards the house.
I just read online that we have mandatory water restrictions as of this evening, though. Lincoln's main well fields are on the Platte near Ashland, about 30 miles northeast of us, and they've had some power issues due to flooding there. The treatment plants have not been impacted so city water is still safe, but the mandatory restrictions are intended to cut usage so that the reserves aren't drained.
