Hello everyone,

We are currently building on a sloped plot in an established residential area. It will still take some time before we start working on the landscaping. At the moment, the area around our house is mostly bare dirt, more or less compacted.

This wasn’t an issue until a few weeks ago when the weather suddenly started bringing heavy downpours on a regular basis. These have now caused muddy runoff streams to flow from our property across the street regularly.

This is frustrating for the neighborhood and unpleasant for us as well. So far, no one (including the construction contractor) has come up with a sensible solution for what we can do about it.

That’s why I’m turning to collective knowledge now. Would you have any suggestions besides digging a deep ditch right at the street or building a wall, which might end up pushing the water toward our house?

Best regards

How large is the area? Coconut mats or erosion control mats could be an option, but for large areas they can also be quite expensive.

Is the problem just the driveway or the entire property?
Is the terrain modeling washing away or the topsoil pile that’s lying around somewhere?

The driveway is actually not the problem; it's the regular topsoil that gets washed away. For the piled-up soil on the slope, I specifically had the weeds removed so it would have some stability. The worst affected area is definitely a strip measuring 3 by 25 meters (10 by 82 feet) on the windward side of the house.

I would cover it with tarpaulins and carry out the shoring in that area fairly quickly.
Water is still flowing, but not as much mud.

Hello,
back then, the landscaper advised me to sow mustard on the earth mounds in the garden. It apparently grows very quickly, stabilizes the soil, and also prevents other weeds from spreading. After plowing it under once, it supposedly does not come back.

However, I didn’t try this myself at the time, so I would suggest asking a landscaper again in your case.

Best regards,

Andreas
