Erection of 4 no. Light Industrial units (Class B1c), associated car and cycle parking and access

Minutes:

The committee received the report of the Interim Head of Development Management, including the relevant planning history of the site.

 

The Development Management Team Leader introduced the report, explaining that the application was for the erection of four light industrial units (Class B1c), associated car and cycle parking and access.

 

The Chair moved the officer’s recommendation.

 

RESOLVED –

 

That planning permission be granted subject to the following conditions:

 

1.       The development to which this permission relates shall be begun within a period of three years commencing on the date of this permission.

 

2.       The development shall be carried out in accordance with the following drawings, unless otherwise approved in writing by the Local Planning Authority. The following drawings are hereby approved:

 

DFW/PL/400, 401

DFW/EX/100, 200

DFW/PL/100, 101, 200, 201, 202

 

3.       No development approved by this planning permission shall commence until a remediation strategy to deal with the risks associated with contamination of the site has been submitted to, and approved in writing by, the Local Planning Authority. This strategy will include the following components:

 

1)       A preliminary risk assessment which has identified:

 

·        all previous uses;

·        potential contaminants associated with those uses;

·        a conceptual model of the site indicating sources, pathways and receptors; and

·        potentially unacceptable risks arising from contamination at the site.

 

2)       A site investigation scheme, based on (1) to provide information for a detailed assessment of the risk to all receptors that may be affected, including those off site.

 

3)       The results of the site investigation and the detailed risk assessment referred to in (2) and, based on these, an options appraisal and remediation strategy giving full details of the remediation measures required and how they are to be undertaken.

 

4)       A verification plan providing details of the data that will be collected in order to demonstrate that the works set out in the remediation strategy in (3) are complete and identifying any requirements for longer-term monitoring of pollutant linkages, maintenance and arrangements for contingency action.

 

          Any changes to these components require the written consent of the local planning authority. The scheme shall be implemented as approved.

 

4.       No development shall commence until a monitoring and maintenance plan in respect of contamination, including a timetable of monitoring and submission of reports to the Local Planning Authority, has been submitted to, and approved in writing by, the Local Planning Authority. Reports as specified in the approved plan, including details of any necessary contingency action arising from the monitoring, shall be submitted to, and approved in writing by, the Local Planning Authority.

 

5.       No development shall commence until a scheme for managing any borehole installed for the investigation of soils, groundwater or geotechnical purposes has been submitted to and approved in writing by the Local Planning Authority. The scheme shall provide details of how redundant boreholes are to be decommissioned and how any boreholes that need to be retained, post-development, for monitoring purposes will be secured, protected and inspected. The scheme as approved shall be implemented prior to the occupation of the building.

 

6.       No development shall commence until the final design of the drainage scheme has been submitted to and approved in writing by the Local Planning Authority. The surface water drainage system will be based on the approved Flood Risk Assessment & SUDS Strategy at Dhamecha Foods, Imperial Way, Watford prepared by Turner Jomas & Associates, dated June 2019 (Version 4.0, Ref: P1851J1558). The scheme shall also include:

 

1.       Detailed engineered drawings of all the proposed SuDS features including their location, size, volume, depth and any inlet and outlet features including any connecting pipe runs and all corresponding calculations/modelling to ensure the scheme caters for all rainfall events up to and including the 1 in 100 year + 40% allowance for climate change event.

 

2.       Demonstrate an appropriate SuDS management and treatment train and inclusion of above ground features such as permeable paving etc. and ensuring appropriate management and treatment of the car parking areas.

 

3.       A management and maintenance plan for the surface water drainage system.

 

7.       No construction works above ground level shall be carried out until details of the materials to be used for the external surfaces of the development have been submitted to and approved in writing by the Local Planning Authority. The development shall only be carried out in accordance with the approved details.

 

8.       No infiltration of surface water drainage into the ground at the site shall take place other than with the express written consent of the Local Planning Authority, which may be given for those parts of the site where it has been demonstrated that there is no resultant unacceptable risk to controlled waters. The development shall be carried out in accordance with the approved details.

 

9.       No piling or any other foundation designs using penetrative methods shall be carried out until a piling method statement (detailing the depth and type of piling to be undertaken and the methodology by which such piling will be carried out and the programme for the works) has been submitted to and approved in writing by the Local Planning Authority. The piling method statement must incorporate measures to demonstrate that there will be no resultant unacceptable risk to groundwater. Any piling must be undertaken in accordance with the approved piling method statement.

 

10.     If, during development, contamination not previously identified is found to be present at the site then no further development (unless otherwise agreed in writing with the Local Planning Authority) shall be carried out until a remediation strategy detailing how this contamination will be dealt with has been submitted to and approved in writing by the Local Planning Authority. The remediation strategy shall be implemented as approved.

 

11.     The development permitted by this planning permission shall be carried out in accordance with the Flood Risk Assessment and SUDS Strategy at Dhamecha Foods, Imperial Way, Watford by Turner Jomas and Associates, dated June 2019 (Version 4.0, Ref. P1851J1558) and the following mitigation measures:

 

1.       Provide attenuation (151.28m3 of storage) to ensure no increase in surface water run-off volumes for all rainfall events up to and including the 1 in 100 year + 40% climate change event.

 

2.       Implement drainage strategy based on restricted surface water discharge at 1l/s and include permeable paving with sub-base and geocellular storage.

 

12.     Prior to any part of the development hereby approved being brought into use a verification report demonstrating the completion of works set out in the approved remediation strategy and the effectiveness of the remediation shall be submitted to and approved in writing by the Local 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.

 

13.     The development hereby approved shall not be occupied until the new on-site car parking spaces and manoeuvring areas have been constructed and laid out in accordance with approved drawing no. DFW/PL/100 (or any subsequent drawing submitted to and approved in writing by the Local Planning Authority). The vehicular access and on-site car parking spaces and manoeuvring areas shall be retained at all times thereafter unless otherwise agreed in writing by the Local Planning Authority.

 

14.     The development hereby approved shall not be occupied until refuse, recycling and cycle storage has been provided in accordance with the approved plans. The storage facilities shall be retained at all times thereafter.

 

15.     Notwithstanding the provisions of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended), and any subsequent legislation that amends or supersedes this Order, the floorspace hereby approved shall only be used for purposes within Class B1(c) of the Town and Country Planning (Use Classes) Order 1987 (as amended) as shown on the approved plans, unless otherwise agreed in writing by the Local Planning Authority.
