We've been living 300m from the county road up a rough 1in10 bohereen for nearly 30 years. The year we moved in 1997, a large part of the surface was washed down to the bottom of the hill by a Summer rainstorm. It didn't help that the clatter of small fields above us had been converted into a single sloped 3½ hectare meadow pointing directly at the lane. In Feb 2010, exactly the same thing happened because a lot of snow thawed in a rush at night. It was only through the power of prayer that we didn't suffer a third washout in 2018.
In 2022, if was fixed that 100 tonnes of top-dress roadstone was delivered by the County Council and spread u the lane by a meitheal of local farmers so that a procession of strangers could walk to the top of our hill. Imagine the shame if someone tripped over a loose stone. It looked pretty spiffing tbh but uncompacted was a bit of trudge for walkers. As we worked away spreading the gravel, I said to anyone who would listen [that would be N = 0] that it was pointless to put this down without sorting out the drainage first. That's three years ago, and we've had plenty rain since then, not to mention a succession of named Storms and the gravel was shaking down nicely as tractors and 4x4s went up and down.In the wee hours of the morning Friday 21st Feb 2025 we had a yellow rain and wind warning. I didn't pay much attention after Darragh and Éowyn romped through in their big girl pants. But at first light the drain was still roaring full of water and I shucked myself into my rain-drain gear including chest-high Aldi waders [as R] to clear any log jams below us. The reason why we washed out in 2010 was because a couple of twigs got caught at the top end of a 30cm culvert and other material built up until the water had to spill up and out into the lane. That's where I was caught by Pete the Post. He had a fine line in dry irony: "where are the neighbours, so . . . is it my back is out or my shovel is broke??". I replied that I was really the only one with skin in the game: the lane would have to get real bucketty before it stopped a tractor or a flock of sheep.
Having reassured myself about the downside, I trudged uphill to see where the water was (still) coming from and make a start on stemming the flow. Above us the water damage [example L] was much worse . . . because I've gone to some trouble to engineer dams and sumps to divert water from the road surface to the parallel drain. The worst part of the roadway would be a challenge to any car - and it's the worst part which is the gatekeeper. After many hours of nighttime rainfall it was bolt-stable-door-after-horse-fled futile, but nevertheless I cut some sods from the margin and dumped them upside down across a low patch in one of the ridges across the road where a positive river was spilling from the mountain. That worked to turn the flow to one side and so served as a diagnostic for where to do something more effective later.The drain had sorted the gravel out in patches where it was a little deeper than average. And I spent a good part of Friday afternoon, in the drain excavating these tailings for a more useful purpose than going further downhill to block things or eventually finish up in Waterford Harbour. That was mildly satisfying as a whole-torso workout. And I filled a few crates with gravel that I could not sensibly spread immediately. Dry gravel has a density a little over 1.5x water. Guesstimating the volume suggests I've captured 150kg of this material for future use rather than immediate waste.
