Having missed the fall driveway paving deadline, we will have a gravel section in the middle of the driveway until next spring. All the water from the garage downspouts and the back yard runs down the driveway, which dumps it directly into the gravel patch and the new retaining wall’s foundation. That means the gravel patch, at least, will become a mud hole, which I take to be a Bad Thing.
So I bandsawed some 4 inch DWV pipe & fittings in half lengthwise, glued them together as a gutter to capture the runoff and divert it into 80 feet of DWV pipe leading to the bottom end of the wall, then filled the half-pipes with gravel to let us drive right over the whole mess. Unfortunately, the top end of the gravel patch has the driveway ending in broken asphalt, Item 4 gravel, fine gravel, and rubble that make it impossible to snug the pipes up against the asphalt. That means the runoff would pretty much vanish before it reached the gutters.
So I excavated just barely enough gravel to ensure a downhill slope from the remaining asphalt, mixed up a random bag of mortar that’s been kicking around in the garage for a few years, and troweled an apron from the asphalt to the half-pipes. Generally I sign my work, but this kludge need last only a few months and I left it to cure.
The next morning I discovered one of the chipmunks felt the work really needed a signature:
That’s OK with me…
FWIW, this is why you need Too Many Clamps:
