)The applicant should address the following points when submitting details to discharge Condition 2:
Full set of calculations for each phase and in total, providing evidence of all surface water retained on site for the 1 in 100 (+40%CC+10% Urban Creep). Any exceedance should be shown with pathways, depths and velocity.
Full drainage drawings showing all connections, control features, storage, inverts etc. and how it communicates with the development wide scheme.
Culverting of existing watercourses will not be permitted.
There should be a minimum 1m between the base of a soakage unit and the seasonal water table.
Any watercourses within or adjacent to the site should be included in the maintenance and management plan, even if there is no discharge to them. This would be a riparian ownership issue but leaving it as such is no longer acceptable.
Under Central Bedfordshire Council and IDB bylaws, any watercourse within or adjoining the site boundary will maintain a 9m development free easement (on the development side), unless otherwise agreed with the relevant drainage authority. This applies to all watercourses, where water is present for all or some of the year, including those not clearly stated on mapping, topography or planning documents.
The connection of private surface water drainage systems to a highway system is not permitted.
Permeable block paving should be laid to CIRIA C768 'Guidance on the construction of SuDS' guidelines. This guidance also stipulates following Interlay guidance.
The Council does not, and is not required to, adopt any SuDS feature. It is the responsibility of the applicant to ensure that the surface water drainage system, in its entirety, will be effectively maintained in the long-term. We therefore expect confirmation of the proposed arrangements for maintenance to be provided with the final detailed design, including the future maintenance and operational needs and the responsible bodies for undertaking maintenance (for all public and private drainage components).
The final detailed design including proposed standards of operation, construction, structural integrity and ongoing maintenance must be compliant with the 'Non-statutory technical standards for sustainable drainage systems' (March 2015, Ref: PB14308), 'Central Bedfordshire Sustainable Drainage Guidance' (Adopted April 2014, Updated May 2015), and recognised best practise including the Ciria SuDS Manual (2016, C753).
Land drainage Consent under the Land Drainage Act 1991 must be secured to discharge surface water to an existing watercourse/ditch, and details of this provided with the full detailed design. An easement should be provided on the developable side of the watercourse to allow for access for maintenance, this should be 9m but may depend on the maintenance requirements considered appropriate.The applicant should address the following points when submitting details to discharge Condition 2:
