southern MN | I’m always puzzled by that.
Yes water flows downhill and you can’t stop that.
But once you change the lay of the land, put in a parking lot or grade the ground or cut a channel you are very much changing how and where that water flows.
It naturally flowed off the land before.
Now it is coming off a packed hard surface that is flat or sloped differently, and likely all the water is channeled to one gusher location, not a sheet of water that flows over a whole slope.
That is a very different water flow than what ‘naturally flowed downhill’ before.
Lot of good replies about just getting it dealt with as it’s a fairly short run, but ive never seen that channeling and directing water downhill is the same as whatever the previous natural flow was.
It’s typically much faster and more concentrated. What might have taken three different paths through three slow low spots before, might now be channeled into one of the low spots, totally changing the water flow and erosion potential downstream.
