Calculation of surface water drained area based on the reqUirements of BUilding. Regulations Approved Document Hand BS EN 752, The eXisting property currently drains via gutters and rainwater pipes to an eXisting. below ground system and benefits from both a front and rear garden. The proposed extensions are below ground in the form of a basement and above ground. to the side I rear, The basement structure will be formed by a contiguous piled wall and does not have any. adverse effects on the area preViously drained due to the nature of the sub soil made. ground over clay other than perched water The footprint of this has therefore been. excluded from the area of consideration, The perched water table is located approximately 500mm below the surface will be. retained by the installation of land drains to prevent a flowpath and protect the below. ground structure by maintaining the current scenario. The additional roof area of the extension is mainly formed over the existing hard paved. area or decking over hard paVing and has been evaluated at 75mm h proposed instead. of 50mm h existing,Existing impermeable area, 50 75m2 roof area 75mm h 78 65m2 hard paved area 50mm h. 1 06 lis 1 10 lis,Proposed impermeable area, 92 40m2 roof area 75mm h 34 30m2 hard paved area 50mmjh.
