Linear channel at garages, doors or the bottom of a slope
Soakaway or crate unit sized to the area and ground
Runoff directed to borders or a permeable strip
Connection to an existing surface-water drain where allowed

Rules in Argyll and Bute

In Scotland, permitted development allows a hard surface between a house and a road only if it is porous or the water drains to a porous area within the property. Unlike England there is no 5 m² allowance, so it applies to any size. Conservation areas and the grounds of listed buildings have extra restrictions. The council, as roads authority, controls any new or widened access across a footway.
