I live at the bottom of a valley, but luckily in a tiny house on a concrete pad, so I have no basement and I'm raised up two feet off the ground. That works pretty well for the house, but the driveway and yard still floods. So I dug a "pond" and small ditch things to channel water to it. You can't really tell where it is because I let my yard grow wild, but when it rains hard the water fills it up, and it evaporates/drains naturally over a couple days. The ditch actually speeds up the water drainage. I dug the ditches to divert the water around the property line, so the surface area of ditch in total is large, even though you can't really see it and it doesn't get in the way. I figure at least a quarter of the water drains through the ditch before it gets to the pond. This is probably helped by the fact that the soil is very rocky.
