| Conditions or Reasons: | 4)
No development approved by this permission shall take place until a Phase 1 Desk Study report documenting the ground conditions of the site with regard to potential contamination has been submitted to and approved in writing by the Local Planning Authority. This report shall adhere to BS10175:2011.Where shown to be necessary by the Phase 1 Desk Study, a Phase 2 Site Investigation adhering to BS 10175:2011 shall submitted to and approved in writing by the Local Planning Authority. Where shown to be necessary by the Phase 2 Site Investigation a detailed Phase 3 remediation scheme shall be submitted for approval in writing by the Local Planning Authority. This scheme shall detail measures to be taken to mitigate any risks to human health, groundwater and the wider environment. Any works which form part of the Phase 3 scheme approved by the local authority shall be completed in full before any permitted building is occupied. The effectiveness of any scheme shall be demonstrated to the Local Planning Authority by means of a validation report (to incorporate photographs, material transport tickets and validation sampling), unless an alternative period is approved in writing by the Authority. Any such validation should include responses to any unexpected contamination discovered during works.
Reason: To protect human health and the environment |
5)
No development shall commence until a detailed surface water drainage scheme, to manage surface water runoff from the development for up to and including the 1 in 100 year event(+40%CC), and a maintenance and management plan for the scheme has been submitted to and approved in writing by the Local Planning Authority. The discharge from the development is to be via infiltration under permeable topping. The final detailed design shall be based on the agreed FRA (Ref: MEC October 2019,25202-01-FRA-01) and DEFRAs Non-statutory technical standards for sustainable drainage systems (March 2018) and shall be implemented and maintained as approved. Maintenance will ensure the system functions as designed for the lifetime of the development. Any variation to the connections and controls indicated on the approved drawing which may be necessary at the time of construction would require the resubmission of those details to the Local Planning Authority for approval. The scheme to be submitted shall include, at a minimum:1.Plans and calculations showing sufficient disposal, storage and conveyance of surface water (up to and including for the 1in100 year event + a 40% allowance for climate change).2.Results of site-specific infiltration testing to support the design of infiltration devices(carried out in accordance with BRE 365).3.Details of the management of existing surface water flows on site and flooded areas for the 1 in 100 year storm when system is at capacity, demonstrating flow paths for design for exceedance.4.Details of the full design and layout of the drainage scheme in its entirety and use of SUDS, including pipe run reference numbers, dimensions, gradients and levels (in metres above Ordinance Datum).5.Overview of proposed construction of the system and any phasing of works.6.Confirmation of the management and maintenance arrangements for the surface water drainage system in its entirety, including any split in public and private responsibilities.
Reason: To ensure the approved system will function to a satisfactory minimum standard of operation and maintenance and prevent the increased risk of flooding both on and off site, in accordance with para 163 and 165 of the NPPF and its supporting technical guidance |
9)
No building operations, site preparation or the delivery of materials to the site other than internal works shall commence until a tree protection strategy, including a tree protection plan and arboricultural method statement (in accordance with the BS 5837:2012 standard), have been submitted to and approved in writing by the Local Planning Authority. The protection measures recommended in the approved tree protection strategy shall be implemented prior to the commencement of building operations, site preparation or delivery materials and remain in position until the practical completion of the development.
Reason: To safeguard trees and the character of the area in A pre-commencement condition is necessary in order to ensure that potential harm is minimised before development reaches an advanced stage. |
14)
No development shall commence until full details of existing and proposed ground levels within the site and on land and buildings adjoining the site by means of spot heights and cross sections, proposed siting and finish floor levels of all buildings and structures have been submitted to and approved in writing by the Local Planning Authority. The development shall then be implemented in accordance with the approved level details.
Reason: As this matter is fundamental to the acceptable delivery of the permission to safeguard the amenities of nearby properties and to safeguard the character and appearance of the area. |
15)
No development shall take place until an Ecological Enhancement Strategy (EES) for the creation of new wildlife features such as hibernacula, the inclusion of integrated bird/bat and bee boxes in buildings/structures, hedgehog holes in fences and tree, hedgerow, shrub and wildflower planting/establishment has been submitted to and approved in writing by the local planning authority. The content shall be informed by an up to date Ecological Appraisal of the site and include the:
a) purpose and objectives for the proposed works;
b) detailed design(s) and/or working method(s) necessary to achieve stated objectives (including, where relevant, type and source of materials to be used);
c) extent and location of proposed works shown on appropriate scale maps and plans;
d) timetable for implementation, demonstrating that works are aligned with the proposed phasing of construction;
e) persons responsible for implementing the works;
f) details of initial aftercare and long-term maintenance.
The works shall be carried out strictly in accordance with the approved details and shall be retained in that manner thereafter
Reason: To ensure development is ecologically sensitive and secures biodiversity enhancements in accordance with the National Planning Policy Framework. |
