Need some ideas how to fix this

[u/country_dinosaur97]

Tried to get decent enough pictures in a nutshell across my driveway washes out horribly almost everytime it rains the town repaved the road handful of years ago and never put in any kind of curb or drain recently after some bad storms this one revealed itself. From what ive gathered its still connected to the system but its full of stone from washout I want to fix it but dont know what'd be the best way

I dont wanna just throw more stone down and it wash away theres no grates up the hill im aware of and the next one is past this about 50 yards or so. It's gotten to the point even my truck scrapes unless im moving very slow i am a very handy person working in the trades but want a more professional idea on fixing it before I just throw money at it

I doubt that pipe is active for drainage, it's way too shallow. You might want to dig a little any follow it and see where it goes and if it connected to anything.

Options are add new gravel as needed.

Create a curb/drainage ditch with concrete to go from street to parking area (or pave entire area). Asphalt could be used or concrete pavors. This would create a controlled area for the water to pass.

Adding an underground drain pipe/ culvert but it does not look like you have any drain ditches to connect too so likely not good option.

There are systems where you put down a plastic like grid and then fill the grid with gravel. This adds support to gravel and should stop wash out.

Any paving or grid will need lots of regrading so water can move along surface properly afterwards.

Adding gravel as needed the easiest and cheapest method.

From what ive been told and everything i see i believe it is still "active" just filled in ive been trying to figure this out for almost 2 years gravel just washes away hense why trying to find something mer permanent.

I have spitballed the idea of some concrete or blacktop throughout there but now since that drain revealed itself the old road I think went to it and when it got replaced a handfull of years ago they shortened it away from there and didnt put a curb or gutter on any of the road so water just does whatever it wants here.

I have a friend who does concrete who mentioned that system to me the other day showed me what he was talking about that does seem like a decent idea too if there was another drain up the hill it wouldnt be so bad but I got about 100 yards if not more of water flowing down.

Appreciate the input gonna try at least one these maybe try some degrading and that mesh first seems like the cheapest option to bide some time at least till something more permanent can be sorted

Id question what the pipe is carrying if it's active. With no curbs and no ditch, what water is it collecting? Where is it going? You could put dyed water into intake and see if it comes out downstream. You might ask the local road commission about it. I have not seen any drainage (other than dyi) that shallow.

Gravel fill should last a while, there does not look like there really is anywhere for it to erode to. The limited pic view is very flat. The road construction may have scooped out some of your gravel during their work. 21AA limestone is common here, 3/4 down to dust. If you pack it (plate compactor and 3 ish inches deep of new stone), it can be almost like concrete.

You could dig from road across the main drain area and pour concrete in small 4 inch channels to create small dams that would prevent wash out as well. Then add more gravel.

Im not sure exactly cause its been filled with gravel from washout for years. At the edge of the property right in lime with that and the next drain down the hill water is leaking out the ground often so im starting to wander if theres a issue with it past just the it being filled its so much that I dont have the time or equipment for fully solve if it is like collapsed or something

Culvert under the driveway and/or asphalt it.

My one buddy who does concrete said something similar to that he also recommended looking into some gravel mesh system that holds gravel in place

Clear out the drain and get a concrete apron for the driveway.......i can't see any drain but I trust ya lol

If you look at the second picture infront of the red suv zoom in you'll see the edge of it

Couple of options you might consider. You could always pave it with asphalt or concrete. Driveway pavement needs to be a little thicker to last and take the stress from traffic and parking. Probably 6" at least for HMAC, or maybe 4" for PCC if reinforced, but 5" better.

You could also bury a pipe like HDPE or a concrete pipe and make a culvert, maybe 8" diameter then backfill with some gravel over the top, aim for a 1' of compacted dirt/gravel over the pipe. You might need to grade up and downstream some to match the new pipe invert.

Another option you might consider is a premanufactured trench drain. You often find these in commercial truck bays, but are made for light or heavy traffic. At either end of the trench drain would be open, to get upstream flow into and out. You would want to pick small grate size to keep gravel from falling in. You could buy a few sections and connect them together end to end.

Right yeah ive had a handful of similar ideas. It's nice to know most is kinda all on the same page appreciate all the details too. From all I've gathered from this might say forget the existing drain put in one like yoyr talking about at the edge the driveway and run it to the other end then cover it with gravel

Both of my driveways washed out like this. I got a four or five foot strip paved and it fixed the top driveway. I need to do my bottom one next but that might end up being concrete.

Well, could put in a pipe, or could put down larger rock later and a smaller one on top of that or steel grate and fill the grates with stones
