A key component of this is using permeable paving where no suitable soak-away area or mechanism on the property for that paving exists. Flood and Water Management Act 2010 sets out the requirements of Sustainable Urban Drainage (SUDS) in which a natural approach to managing drainage in and around properties and other developments is required. These permeable paving blocks can be used to gain credit in your planning applications with regard to Sustainable Urban Drainage (SUDS) considerations.Īs part of the wider solution to Surface Water Flooding, the Government has made a series of changes to legislation, guidance and planning regulations. House Builders & Developers - Environment & Sustainability To prevent this “flash flooding” phenomena, they introduced new planning guidance requiring the use of permeable paving where no run-off into lawns/borders was possible to prevent the water from reaching the street and mains sewers. The Environment Agency conducted studies that showed that 66% of surface water flooding where the mains drainage was overwhelmed was caused by run-off rainwater from driveways and paved areas. The UK Government changed planning regulations in 2008 following major flooding across the country the previous year. Using permeable paving for driveways or paved areas at the front of your property will allow you to install it without requiring planning permission if you have no lawn areas or borders into which any run-off water can drain. Homeowners - Avoid Need for Planning Permission This allows rainfall to naturally soak into the ground and prevents it from running off into unwanted areas (such as the street at the front of your home) which could contribute to localised flooding during downpours. These blocks are designed to allow water to pass between the blocks and soak-away beneath your paved area. These permeable grid block pavers have a depth of 100mm making them suitable vehicle parking areas and driveways. As with every construction project, it is always advisable to check with the relevant local planning authority prior to starting your project. GrassPark facilitates natural drainage of rainwater into the subsoil and, as such, should negate the requirement for planning permission when used to pave front gardens for hard standing. Environment & Sustainability - permeable paving should be considered by housebuilders and developers for both your Sustainable Urban Drainage plan and to ensure you're aligned with BREEAM advice to assist you with any planning application you're undertaking.Avoid Planning Permission - if you are using permeable paving to pave your own domestic driveway or area at the front of your property, then you can do so without applying for planning permission.
