Hello everyone,
I hope I am in the right subforum here (or would horticulture have been better?).

Since our building plot is in the second row (331), we, together with our neighbors (332), have purchased a second parcel of land as an access road (337). It is about 30m long and about 3m wide. So far, I thought we would simply pave it and drain the rainwater into the sewage water canal (of course with a drainage application).
Yesterday I called the AZV. They told me that we are not allowed to discharge the water there because parcel 337 does not have a connection to the canal. We are not allowed to use the canal of our residential building. Instead, we should use permeable paving and avoid any gradient.

Avoiding a gradient is, in my opinion, total nonsense because I do not want to walk through puddles.
So what to do? Would picture 2 be a solution? Or do you have a better idea?

Below are 2 pictures:
Picture 1 shows the parcels: our house is being built on 331, our neighbors have 332. The access road is parcel 337, the adjoining street is parcel 339.
Picture 2: my idea for drainage: our street in cross-section: (from right to left) curbs, permeable paving, lowered curb, gravel pit, curb



Best regards
Simon

Hi,

permeable paving definitely works. We installed something like this (the stone is called: Rinn Hydropor Padio Splittfuge, from Rinn Beton- und Naturstein GmbH) because we could only achieve a gradient of 1% max. It’s great, even with extreme heavy rain no puddles form. And the city can’t charge drainage fees for the area. Of course, the substrate has to allow it. It doesn’t work on clay soil...

Best regards,

Andreas
