The provisions of the Construction Management Plan shall be implemented in full during the period of construction and shall not be varied unless otherwise agreed in writing by the LPA.

10. The parking provision shown on the approved Proposed Site Plan (Dwg no. P402 rev. E) shall be provided prior to first occupation of the building hereby approved. The parking area shall be hardsurfaced and shall be made available for its intended use at all times thereafter unless otherwise agreed in writing by the local planning authority.

11. The development permitted by this planning permission shall be carried out in accordance with the principles set out within the flood risk assessment (Rev 1, 02/12/2021, Tier Consult). The measures shall be fully implemented prior to the first use of the development and in accordance with the timing / phasing arrangements embodied within the

scheme, or within any other period as may subsequently be agreed, in writing, by the local planning authority in consultation with the lead local flood authority.

12. Prior to the commencement of development, details of a sustainable surface water drainage scheme and a foul water drainage scheme shall be submitted to and approved in writing by the Local Planning Authority. The drainage schemes must include:

(i) An investigation of the hierarchy of drainage options in the National Planning Practice Guidance (or any subsequent amendment thereof). This investigation shall include evidence of an assessment of ground conditions and the potential for infiltration of surface water in

accordance with BRE365;

(v) Foul and surface water shall drain on separate systems.

The approved schemes shall also be in accordance with the Non-Statutory Technical Standards for Sustainable Drainage Systems (March 2015) or any subsequent replacement national standards.

Prior to occupation of the proposed development, the drainage schemes shall be completed in accordance with the approved details and retained thereafter for the lifetime of the development.

13. No tree felling, scrub clearance, hedgerow removal, vegetation management and / or ground clearance is to take place during the period 1 Marc to 31 August inclusive. If it is necessary to undertake works during the bird breeding season then all trees, scrub, hedgerows and vegetation are to be checked first by an appropriately experienced ecologist to ensure no breeding birds are present. If present, details of how they will be protected are required to be submitted for approval, and the approved details adhered to in full.

14. The development hereby permitted shall not be occupied until details of bird boxes to include number, type and location on an appropriately scaled plan as well as timing of installation, has been provided for approval and implemented in accordance with those

details.

15. The development permitted by this planning permission shall be carried out in accordance with the principles set out within section 5.4.2. of the Ecological Impact Assessment (Ref: August 2022RSE_5581_R1_V1_ECIA).

18. If, during the undertaking of site works, contamination not previously identified is found to be present, then further site works shall be suspended until the extent of contamination has been determined and defined in agreement with the local planning authority. Written Agreement shall then be obtained from the local planning authority to enable onsite works to recommence within the area(s) not affected by the contamination identified.

Works shall not recommence with the defined area of contamination until the developer has submitted and obtained written approval, from the local planning authority, of a remediation strategy detailing how the identified contamination shall be dealt with. The remediation

strategy shall be implemented as approved.

planning authority. The report shall include results of sampling and monitoring carried out in accordance with the approved verification plan to demonstrate that the site remediation criteria have been met.

20. No development shall take place on site until a Site Waste Management Plan confirming how demolition and construction waste will be recovered and re-used on the site or at other sites, has been submitted to and approved in writing by the Local Planning Authority. The approved plan shall thereafter be implemented in full unless otherwise agreed in writing.

21. No development shall commence until a final detailed sustainable drainage design for the management and disposal of surface water from the site, has been submitted to and approved in writing by the Local Planning Authority, in consultation with the Lead Local Flood Authority. The details of the ‘Final’ Sustainable Drainage Strategy must be based on the principles and details identified in Proposed Foul and Surface Water Drainage Layout (T_21_2487-55-01 rev P2 dated 1 March 2022 – drawing produced by Tier Consult).

The final Detailed Sustainable Drainage Design will be required to comply with DEFRA’s

technical standards for sustainable drainage systems and the SuDS Manual and include:

• Justification of final design

• The new outfall/headwall shown on the Proposed Foul and Surface Water Drainage Layout drawing (T_21_2487-55-01 rev P2 dated 1 March 2022) is shown as outside the red line boundary; therefore written confirmation / evidence is required to prove / confirm the surface water outfall / headwall is situated within land owned / controlled by the applicant or provision of evidence of a legal agreement between the applicant and the land owner is required.

• Provision of evidence of any licences and agreements that must be obtained / required for provision of a new outfall / headwall into The River Mersey at an uncontrolled discharge rate.

• Drawings to include:

- Final layout of roads, buildings, finished floor levels, external levels and boundaries;

- Final layout of sewers; outfalls; SuDS; flow control details (must match flow control in calculations) hatched above ground storage areas with depths indicated;

- Overland flow paths designed for exceedance of the 1 in 100 plus climate change event, system blockages, etc. An impermeability of 100% for the whole site area (including soft landscaped areas) should be used in all cases when determining exceedance flows;

- Invert levels (to OS datum), manhole and pipe sizes; pipe gradients; SuDS; emergency overflows and annotation that correlates to the hydraulic calculations;

·  Hydraulic modelling for final drainage strategy to include:

- System performance for following return periods; 1, 30, 100 plus appropriate current climate change allowance;

- Demonstration of sufficient storage for the 1 in 100 year (plus climate change) critical rainfall event with a limiting discharge rate as stated in the above referenced drainage strategy;

- Design criteria summary, Full network details table, pipe and manhole schedules, contributing area summary, control/storage structure details, results summary print outs;

- Flow control device design calculations demonstrating compliance with limiting discharge rate as stated in the above referenced drainage strategy at the correct design head;

- Volumetric runoff co-efficient (Cv) should be set to ‘1’;

- Apply the correct climate change allowance: For further information on the correct

climate change allowance to apply you should refer to ‘Flood Risk Assessments:

Climate Change Allowances’.

• Timetable demonstrating completed SuDS construction prior to occupation

• Construction phase surface water management plan

22. The development hereby permitted by this planning permission, including all components of the sustainable drainage system, shall be carried out in accordance with the approved final Sustainable Drainage Strategy, including any phasing embodied within, and maintained in perpetuity in accordance with an agreed Operation and Maintenance Plan, to be submitted for each development phase, approved by the Local Planning Authority, in consultation with the Lead Local Flood Authority.

The approved drainage scheme shall be fully constructed prior to occupation in accordance with the approved details, phasing and timetable embodied within the approved final Sustainable Drainage Strategy, or within any other period as may subsequently be agreed,

in writing, by the Local Planning Authority in consultation with the Lead Local Flood Authority.

‘As built’ drainage design/layout drawings and a final Operation and Maintenance Plan, confirming asset details and maintenance arrangements, shall be submitted to the Lead Local Flood Authority, in accordance with any approved phasing, prior to occupation.
