So if you remember back to last week my swale resembled a river, and was rather destructive.
Here is the problem.
The bottom of the swale is carrying a pitch. This is no good. It is also carrying a pitch from front to back. This allows it to form a river that runs up against the berm instead of landing and holding still.
What needs to be done now is to dig out the excess and re establish level across the whole swale. The first steps here are to peel back the mulch, which has proven to be more of a problem than a solution. The buoyancy of the wood chips allows the water to flow over and around them, ultimately picking them up and depositing them in the garden.
What I’m after is level ground end to end. This will break the tendency for the water to start running. The next task is to level the ground front to back. This will keep the water from pushing directly under the berm.
Here is the first section done. It is level across an eight foot stretch and level front to back sampled about every six inches.
naturally one project lends itself to another the terrace is being born.
That’s all I have light for now. Join me next time as we finish this project off.
Until next time…
