SUDs on a slope

[Post and beam]

It looks like i will need to provide a ramp/slope from the driveway to the path in front of the house.

This will also need to be SUDs compliant i guess. So what is the recognised and preferred method to do so? All of the articles i can find so far describe the build up of a flat and level surface.

There is a roads document that details the slopes required and where the acro drain is located so you don't get slippage on to the road. It basically has to comply with highways regs. Your slope itself is likely to have to SUDs compliant also
