The Local Planning Authority has no objection to Drawing 2846 P01 (Proposed Site Plan) superseding Site Layout Plan Drg. No. 21414 P0002 Rev K

Prior to commencement of development (except groundworks) detailed calculations and drawings should be provided for the full drainage strategy and report to include: Details of that the proposed surface water drainage system has been designed to prevent surcharging in all events up to an including the 1 in 2 annual probability storm event, prevent any flooding of the site in all events up to and including the 1 in 30 annual probability storm event. This report should also demonstrate that surface water runoff up to the 1 in 100 year event plus climate change will be controlled without causing harm to people or properties. Details to demonstrate how the system of swales and basins actually function and how they are to drain after an event. This should also include commentary on how the building floor levels and ground levels across external areas compare to design water levels within the swales and basins. Detailed drawings illustrating the proposed surface water drainage system including location of SuDS features, manholes, external pipework, attenuation features and discharge locations. These drawings should illustrate that the proposed attenuation structures are not located within an area at risk of fluvial or surface water flooding up to the 1 in 100+ climate change annual probability event, and rational behind this if this is the case. Design should account for a potential surcharged outfall to the watercourse with supporting calculations etc. Design calculations should use FEH rainfall and the system should be designed with climate change allowances of 45% based on current government requirements. Provisions within the site for the disposal of surface water so as to prevent its discharge onto the highway The approved drainage system shall be implemented in accordance with the approved Sustainable Drainage Strategy prior to the use of the building commencing and maintained thereafter for the lifetime of the development. Reason: To prevent the increased risk of flooding by ensuring the provision of a satisfactory means of surface water disposal is incorporated into the design and the build and that the principles of sustainable drainage are incorporated into this proposal and maintained for the lifetime of the proposal

Prior to commencement of any works in the highway a survey of the condition of the adopted highway shall be submitted to and approved in writing by the Local Planning Authority. The extent of the area to be surveyed must be agreed by the Highways Authority prior to the survey being undertaken. The survey must consist of: - A plan to a scale of 1:1000 showing the location of all defects identified; - A written and photographic record of all defects with corresponding location references accompanied by a description of the extent of the assessed area and a record of the date, time and weather conditions at the time of the survey No building or use hereby permitted shall be occupied or the use commenced until any damage to the adopted highway has been made good to the satisfaction of the Highway Authority. Reason: to ensure that any damage to the adopted highway sustained throughout the development and construction process process can be identified and subsequently remedied at the expense of the developer in accordance with Policy D13 of the Local Plan.

Prior to commencement of any works in the highway a detailed plans have been submitted to and approved in writing by the Local Planning Authority relating to line, level and layout of the access road junction / off site improvements to Pillmore lane and its means of construction and surface water drainage as shown generally in accordance with drawing HIGH-CDY-XX-XX-DR-C-0044 Rev P01. The approved access road junction / highway improvements shall be laid out and constructed in accordance with the requirements of a Section 278 Agreement under the provisions of the Highway Act 1980 prior to the development first being brought into use. Reason: In the interests of highway safety in accordance with Policy D13 of the Local Plan.

Prior to the completion of the development, details of a scheme for the management of foul and surface water in line with the document 1261 HIGH-CDY-XX-XX-DR-D-0500 Rev P04 dated 20/01/23 should be submitted to , and approved in writing by the Local Planning Authority. The scheme shall be managed and maintained in accordance with the approved scheme for the lifetime of the development. Reason: In the interests of flood prevention in accordance with Policy D1.
