And once dug, what are you doing with the ditches? Will you fill with organic matter? Are these to be swales of sorts, to moderate the water level in the soil by infiltration? I was just thinking that as your neighbour's spot is two metres lower than yours, it already has somewhere to go, it just needs perhaps something deeper rooted to give the water a path.
What have you been growing in the space? You noted that the soil was good. I was just thinking that, if the ditch itself doesn't do it all, you could try daikon radishes or mangelwurtzels, some deeply-taprooted veg that you needn't even eat yourself, or even pull from the soil, and it would give the water channels down, probably much nearer your mineral layer.
But I am speculating when I needn't. What do the soil layers look like? How deep is this silty soil of yours, and what's underneath it? As in, is it a clay or compacted layer underneath that's keeping the water in place, or is it the particle size of the silt?
This is exciting, in any event. Thanks for sharing your project. Please keep us updated, and good luck!

That layer of clay is what is causing your land to flood with what I would consider to be avg amount of rainfall.
The only difference is that the clay is exposed at the top and at other places it is maybe 2meter deep
