Is subject to call in?: No

Decision:

RESOLVED: That application 21/02076/FP be GRANTED planning permission subject to the reasons and conditions outlined in the report of the Development and Conservation Manager and the following amendments to conditions:

 

·         Condition 1 to be added with the following:

 

The development permitted by this planning permission shall be carried out in

accordance with FRA and Drainage Strategy E20-064 Issue 4 dated November 2021

prepared by SDP Consulting Engineers including Appendices 1-19. and the following

mitigation measures; 

 

1. Limiting the surface water run-off rates for all rainfall events up to and including the

1 in 100 year + climate change event with discharge via two deep bore

soakaways.

2. Provide attenuation to ensure no increase in surface water run-off volumes for all

rainfall events up to and including the 1 in 100 year + climate change event

through the use of permeable driveways, permeable access road with sub-base

and a detention pond. 

3. Implement drainage strategy as indicated on the proposed drainage strategy

drawing E20-064-1001 P4 dated December 2021 prepared by SDP Consulting

 

 Reason :To reduce the risk of flooding to the proposed development and future occupants

 

·         Condition 2 to be added with the following:

 

No development shall take place until the final design of the drainage scheme is

completed and sent to the LPA for approval. The surface water drainage system will be

based on the submitted FRA and Drainage Strategy E20-064 Issue 4 dated November

2021 prepared by SDP Consulting Engineers including Appendices 1-19. The scheme

shall also include;

 

1. Detailed engineered drawings of the proposed SuDS features (Permeable

driveways, permeable road with subbase and pond) 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 climate

change event. 

2. Infiltration bore holes tests to be undertaken in the exact location of the two

proposed deep bore soakaways to determine the worst-case infiltration rate to be

used to finalise the proposed attenuation pond design.

3. Cross sections of the proposed pond including the permanent water level,

freeboard and the additional 1 in 30-year rainfall event.

4. Demonstrate an appropriate SuDS management and treatment train and inclusion

of above ground features such as permeable paving, swales etc. for the access

road and reducing the requirement for any underground storage. 

5. Silt traps for protection for any residual tanked elements.

6. Final detailed management plan to include arrangements for adoption and any

other arrangements to secure the operation of the scheme throughout its lifetime. 

7. All drawings should be final, ready for construction and not subject to change.

Reason :To prevent flooding by ensuring the satisfactory storage of and disposal of surface water from the site

 

 

 

 

·         Condition 22 to be added with the following:

 

“Prior to the commencement of the development hereby permitted, a feasibility study into the installation of UV solar panels within the development shall be submitted to and approved in writing  by the Local Planning Authority. The study shall include provision for the installation of such panels where they are deemed to be feasible. Such works shall thereafter be carried out in accordance with the approved details or particulars prior to the occupation of the dwellings to which they relate unless otherwise agreed in writing by the Local Planning Authority.

 

Reason: In the interest of delivering sustainable homes”

 

·         Condition 23 to be added with the following:

 

“Prior to the commencement of the development herby permitted, full details of measures to minimise water use and consumption shall be submitted to and approved in writing by the Local Planning Authority.

Reason: In the interest of delivering sustainable homes”
