)Drainage Notes
We would expect some above ground sustainable drainage features (as per our SuDS SPD). Some SuDS features/diversity enhancement in all phases.
We will require full drainage drawings showing all connections, control features, storage, inverts etc.
We will require BRE365 infiltration test results. Even if this does not meet requirements infiltration could be combined. This may solve half drain times.
Culverting of existing watercourses will not be permitted.
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.Drainage Notes

)NatureSpace Notes:
It is recommended that the NatureSpace Best Practice Principles are considered and implemented where possible and appropriate.
It is recommended that the NatureSpace certificate is submitted to this planning authority at least 6 months prior to the intended commencement of any works on site.
It is essential to note that any works or activities whatsoever undertaken on site (including ground investigations, site preparatory works or ground clearance) prior to receipt of the written authorisation from the planning authority which permits the development to proceed under the District Licence (WML-OR152, or a 'Further Licence') are not licensed under the great crested newt District Licence. Any such works or activities have no legal protection under the great crested newt District Licence and if offences against great crested newts are thereby committed then criminal investigation and prosecution by the police may follow.
It is essential to note that any ground investigations, site preparatory works and ground / vegetation clearance works / activities (where not constituting development under the Town and Country Planning Act 1990) in a red zone site authorised under the District Licence but which fail to respect controls equivalent to those detailed in the planning condition above which refers to the NatureSpace great crested newt mitigation principles would give rise to separate criminal liability under the District Licence, requiring authorised developers to comply with the District Licence and (in certain cases) with the GCN Mitigation Principles (for which Natural England is the enforcing authority); and may also give rise to criminal liability under the Wildlife & Countryside Act 1981 (as amended) and/or the Conservation of Habitats and Species Regulations 2017 (as amended) (for which the Police would be the enforcing authority).NatureSpace Notes:
