There is a corner of my house where water tended to collect, to the
point that the window well filled up. There is a downspoutthere, as
well as a low area. I corrected the problem by trenching away from
the house, and I am building up the dirt a little there. I put
extensions on the downspout to feed into the top of the trench, which
is shallow and gradually sloped.
The problem of the water collecting there seems to have been solved,
but now it is diverted toward the sidewalk, maybe 50 feet away. This
is not a problem with normal rain, but when we get a torrential
downpour, dirt tends to get on the sidewalk. In the Srping, with
snowmelts, I think it may be the same. To alleviate this, we are
planning to put in a drybed with river rock over landscape fabric. On
either side, we have put in a garden with mulch. I think the
appearance will be great, and more important, my wife thinks so.
On to my question. My intention right now is to put the drybed in
with the hope that the rocks and landscape fabric will contain most of
the dirt runoff. In order to minimize the runoff of water onto the
sidewalk, I was considering digging postholes 4 feet down, every 10
feet or so and putting in 4" PVC to carry water down, sort of like a
drywell. To keep the rocks from falling into the PVC pipes, I thought
I would put hardware cloth over them.
So, the plan is this: Along the approximately 50' swale, sink 5 or 6
PVC mini-drywells with hardware cloth to keep them open, laying
landscape fabric over the entire thing, and putting in about 2" of
Any comments, suggestions, "you're crazy, that won't work" comments?
