We're high, but not quite at the top. At the moment the slight rise from our crazy paving helps water to continue along the pavement and down to the curb. But it is a concern for any future work as fucking it up would send a shit tonne of run off water down next to our house.
This was the other thought behind planted cutouts in the paving as it would also act as a sort of sink hole. When we redo the terrace in our back garden I'm quite keen to add a half meter square hole a meter deep filled with gravel and a water loving plant in the wettest corner to make sure no water comes near the house. Again we get quite a bit of run off from the uphill gardens.
Judging by other peoples' drives I think there is a mix of jdgaf and sensible use of ecobase + gravel. But no real enforcement.
An awful lot depends on what soil you are on. If it's clay you'll just have an overflowing pond in a wet winter. A starting point would be to work out the area of paving and multiply by 50mm (a day of extremely heavy rain) to work out the volume of water you could be dealing with.
