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 County Tyrone

In Northern Ireland, the Planning (General Permitted Development) Order (Northern Ireland) 2015 allows a hard surface between the front of a house and a road without permission if it is porous or drains to a porous area within the property, once it exceeds 5 m². Listed buildings and some access changes need permission. Any new or altered vehicle access onto a public road needs approval from DfI Roads, not the council.
