development and future occupants.
6. Applications for the approval of the Reserved Matters referred to in
Condition No 2 shall include a surface water drainage scheme for
the site, based on sustainable drainage principles and an
assessment of the hydrological and hydrogeological context of the
development. The scheme shall subsequently be implemented in
accordance with the approved details before the development is
completed. The scheme shall also include: surface water discharge
limited to 1.4l/s/ha, attenuation to accommodate storm water from a
1 in 100 year return period, include an allowance for climate
change, detailed calculations, details of how the scheme shall be
maintained and managed after completion and consideration of how
surface water discharged to soakaway will be managed to avoid
increasing the risk of groundwater flooding.
INFORMATIVE: Environment Agency records suggest that resting
groundwater depth on site is 1mbgl.
Reason: To prevent the increased risk of flooding, and ensure
future maintenance of the surface water drainage system.
7. The site shall be developed with separate systems of drainage for
foul and surface water on and off site.
Reason: In the interest of satisfactory and sustainable drainage.
8. No piped discharge of surface water from the application site shall
take place until works to provide a satisfactory outfall for surface
water have been completed in accordance with details to be
submitted to and approved by the local planning authority before
development commences.
Reason: To ensure that the site is properly drained and surface
water is not discharged to the foul sewerage system which will
prevent overloading.
9. No development shall take place until details of the proposed
means of disposal of foul water drainage, including details of any
balancing works and off-site works, have been submitted to and
