Culvert do-over ... rocks?

[jimh406]

As part of the Spring road rebuild, the neighbors dug out the culvert next to my driveway entrance that I didn’t even know existed. The goal is to prevent the gravel road from washing out.

I’m on the uphill side/entrance to the culvert. Should I add big rocks on the uphill side, etc? I’m having a hard time finding examples of how to landscape it. I have lots of larger rocks on my property, so I could just bring a few down. Of course, I could also put gravel in there and plant grass back. Ideal would be to make it hard to fill back up again while also making it relatively safe if someone went off the road into the hole. There was several feet of clay/dirt in the hole before.

Fyi, we only have about 12 inches of precip a year, so a flash flood is somewhat rare and low volume. Most of the damage is from snow build up and melt.

a picture would help but...
maybe a semi circle of rocks,say 1-2 feet away from the culvert opening, is what you need ? The 1-2ft gap allows water to seep/run into the culvert, keeps most silt/dirt out.
I see that here, at the ends of culverts that go 'under' driveways and into fields. The big rocks WARN you there's a tire rippin piece of steel nearby !!!

As GreensvilleJay mentioned, you're asking if a woman is pretty and we can't see the picture, so your answer can only be as good as the question!

Might rip-rap it like you see on some dam intakes using the rock you already have.

Thanks for your helpful comment.

I put a 6' pipe in my creek. I used 6-12" rip rap on the upstream side and drove t-post in front of the rock to help hold them in place. Then filled over the top with dirt and packed it down around the rock from the top side. It's held up very well.
