I'm thinking of creating a berm on my lawn. The steps in most of the how-to instructions I find say to remove the grass first. I'm wondering why? Couldn't one just put soil on top of the grass? Won't the grass just die under the berm? Any insight or wild guesses welcome!
Why remove grass for a berm?

Yes, that is exactly what I would do...put the dirt on top of the grass where you want the berm.
Yes, and no.
Most of it probably will die. Along the edges where the layer is thinner, grass might pop through, especially if you have any aggressive invasive grasses in your lawn.
Adding mulch and edging can definitely diminish how much weed development in your embankment.

It is amazing what depth grass can grow up from sometimes, on the other hand the dead grass makes a good addition to the soil. I would take up the turf and simply turn it over, then put your dirt on top, maybe chuck a few inches from around the edge into the middle. Unless you want it grassed, then take up the grass as turfs so you can put them back after.
