| Conditions or Reasons: | 8)
Development shall not commence in an area, as defined by the areas plan required by condition 3, until a surface water drainage scheme for that area, based on sustainable drainage principles and an assessment of the hydrological and hydro geological context of the development, has been submitted to and approved in writing by the Local Planning Authority. The scheme shall subsequently be implemented in accordance with the approved details before the development of the relevant area is completed.
The scheme shall also include:
Details of investigatory ground investigation testing with a view to demonstrating the viability of infiltration drainage for some or all of the site;
Full details of proposed surface water runoff in all catchments (as identified in the agreed Flood Risk Assessment) demonstrating compliance with the agreed discharge rates for each catchment contained within Table 6-2 of the Flood Risk Assessment dated 19 May 2011, reference 2725/FRA revision 2, compiled by WSP, or to revised discharge rates submitted and approved in writing by the Local Planning Authority
Full details of all components of the proposed drainage system including source control, conveyance, storage, flow control and discharge. Details shall include dimensions, locations, reference to storm simulation files, gradients, invert and cover levels, and drawings as appropriate. This shall be completed for all catchments identified;
Full details of overland flood low routes (as well as likely depths and velocities) in the event of system failure or exceedance. Demonstration shall be given that flood risk in these circumstances shall not increase to either the site or to sites downstream of, or adjacent to, this site;
Evidence of agreement of the Internal Drainage Board to the proposals;
Full details of the maintenance and/or adoption proposals for the development, covering every aspect of the proposed drainage system;
Reason: To prevent the increased risk of flooding, to improve and protect water quality, and ensure future maintenance of the system, in accordance with policies 44 and 49 of Development Strategy for Central Bedfordshire (Revised Pre-Submission Version June 2014). |
