SUSTAINABLE URBAN DRAINAGE
SUDS: PLANNING RULES FOR DRIVEWAYS
In 2008, as a result of an increase in local flooding specific rules were introduced for householders wanting to pave over their front gardens. If the surface to be covered is more than five square meters, planning permission will be needed for laying traditional, impermeable driveways that do not provide for the water to run to a permeable area.
However, if a new or replacement driveway of any size uses permeable (or porous) surfacing which allows water to drain through, such as gravel, permeable concrete block paving or porous asphalt, or if the rainwater is directed to a lawn or border to drain naturally, planning permission will not be required.
For more information regarding the importance of using a permeable surface for front gardens, see the Government Planning Guidelines or the UK Planning Portal.
OPTIONS FOR MEETING SUSTAINABLE URBAN DRAINAGE RULES
Methods that Meet Drainage Regulations are:
Install permeable paving that allows water to soak away through the joints between paving, the water then drains away.
Install linear drainage channels
Ensure water drains into soft garden borders or lawns.
GroundGuard is a lightweight ground reinforcement system ideal for grass or gravel stabilisation. The system helps to reduce the risks of potholes, rutting or grass damage.
The system can handle loads of up to 250 tonnes per m2, making it ideal for driveways, parking areas, access routes, paths and shed bases.
There porous so providing effective drainage of surface water and saving cost on unnecessary drainage installation.
Permeable Block Paving
When permeable block paving is laid as part of a permeable solution on the correct sub base any water that lands on it simply drains away between the blocks, stopping surface water from collecting, this satisfies all the legislation regarding front driveways
Where permeable paving not used Channel drainage solutions are typically designed for efficient removal of surface water
