Hi Allister,

As discussed on the phone, our recommendations intended that the vast majority of stormwater would go to the
street, given the height of the house – this seems to be what you have planned anyway.

For such ‘clean’ sands ranging fine to medium grained (as were logged at this site) a coefficient of permeability of 1
x 10 -4 m/s could be used for design. This is taken from Craigs Soil Mechanics, and is referenced further in there back
to BS8004.


Best Regards,

Robert
