Archaeology

9.              Prior to any demolition and the commencement of the development a professional archaeological organisation acceptable to the Local Planning Authority shall prepare an Archaeological Written Scheme of Investigation, relating to the application site area which shall be submitted to and approved in writing by the Local Planning Authority.

10.           Following the approval of the Written Scheme of Investigation referred to in condition 6, and prior to any demolition on the site and the commencement of the development (other than in accordance with the Written Scheme of Investigation), a staged programme of archaeological evaluation and mitigation shall be carried out by the commissioned archaeological organisation in accordance with the approved Written Scheme of Investigation.

Drainage

11.           Development shall not begin until a revised surface water drainage scheme, based on the drainage principles listed below have 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 is completed. The drainage must include but not be limited to:

·       Evidence that the proposed flows from the site will be restricted to greenfield run-off rates for all events up to and including the 1 in 100 year event+ allowance for climate change (currently 40%)

·       Evidence that the proposed run-off volume will not increase the existing greenfield volume for the corresponding event

·       Details of how the drainage scheme has been designed to incorporate SuDS techniques to manage water quantity and maintain water quality in accordance with best practice guidance including the latest SuDS manual C753

·       Detailed drainage plan showing the location of the proposed SuDS and drainage network with exceedance flow routes clearly identified

·       Detailed drainage calculations for all rainfall events up to and including the 1 in 100 year plus climate change event to demonstrate that all SuDS features and the drainage network can cater for the critical storm event for its lifetime

·       Details of how the scheme shall be maintained and managed after completion. Construction phase surface water management plan including details of how water quality shall be maintained during and after construction

·       The submission of evidence relating to accepted outfalls from the site, particularly from any third party riparian or network owners

12.           The development shall be implemented in accordance with the approved Habitat Creation and Restoration Scheme (NLG Ecology 24^th May 2018) and illustrated on drawing numbers 151661-NWR-DRG-ECV-HCR.1-3 inclusive. Any variation to the approved plan shall be agreed in writing with the Local Planning Authority before such change is made.

The report is to detail appropriate mitigation measures should they be considered necessary, including any amendments to the approved scheme. Thereafter the development shall be carried out in accordance with the approved details.

14.           The development shall be carried out in accordance with the FRA (Blackthorn and Piddington Rail Embankment Stabilisation, Revision 2.1, Atkins March 2019) and the following mitigation measures detailed within the FRA

·       A minimum of 1,909m3 of compensatory flood plain storage is provided as shown in Table 5-2, section 5.1.4 of the FRA

·       Where the access track is located within the floodplain, it will be set at existing ground level as per section 5.1.2 of the FRA

The mitigation measures shall be fully implemented prior to occupation and subsequently in accordance with the timing/phasing arrangements embodied within the scheme, or within any other period as may be subsequently agreed in writing by the local planning authority.

15.           No development shall take place until the Blackthorn and Piddington Railway Embankment Stabilisation Habitat Creation and Restoration Scheme and Blackthorn and Piddington Biodiversity Monitoring and Maintenance Scheme documents are updated to reflect the changes to the scheme as detailed in the Technical Memo 100454-NWR-MEM-ECV-000005 dated 18/12/18. The updates should include details of the location and number of coir rolls being installed, species list for any new planting or seeding and monitoring and management prescriptions for the new features being created.

16.           Contamination report

17.           Verification of contamination report

18.           Contamination not previously identified

19.           Prior to the commencement of the development hereby approved, a landscaping scheme shall be submitted to and approved in writing by the Local Planning Authority. The scheme for landscaping shall include details of the proposed tree and shrub planting including their species, number, sizes and positions, together with grass/turfed areas, details of the existing trees to be retained a swellas tose to be felled, including existing and proposed siol levels at the base of each tree/hedgerow and the minimum distance between the base of the tree and the nearest edge of any excavation and the details of hard surfaced areas, reduced dig areas, crossing points etc
