Demolition of existing garages and replacement with permeable block paving open parking spaces and new 2000mm high close boarded fences to neighbouring properties

1. The development hereby permitted shall be begun before the expiration of three years from the date of this permission. Reason: In accordance with Section 91 of the Town and Country Planning Act 1990 (as amended).
2. The development hereby permitted shall be retained in accordance with the following approved plans: - Site Location Plan Proposed Elevations - CKH-GP-EAW-06 Block Plan - CKH-GP-EAW-05 Proposed Site Plan - CKH-GP-EAW-04 Existing Garage Elevations - CKH-GP-EAW-03 Existing Site Plan - CKH-GP-EAW-02 Site Location Plan - CKH-GP-EAW-01 Reason: For the avoidance of doubt and in the interests of proper planning
3. Prior to the commencement of development beyond site clearance, a surface water drainage scheme shall be submitted to and agreed in writing with the Local Planning Authority. The scheme shall include but not be limited to: o Demonstration of the discharge surface run off being as high up the hierarchy of drainage options as reasonably practicable and the use of treatment trains. o Demonstration of the areas of permeable and non-permeable hard surfacing. o Details of existing surface water risk of the site. o Discharge rates limited to the greenfield 1 in 1 year rate or 1l/s, whichever is lower. Where it is not possible to meet the greenfield 1 in 1 rate, demonstration of its unfeasibility shall be provided, and rainwater re-use should be used to reduce the runoff rate from the site. o Sufficient storage should be provided to ensure no internal flooding as a result of the development during all storm events up to and including the 1 in 30 year storm event and no off site flooding as a result of the development during all storm events up to and including the 1 in 100 year plus 40% climate change event. o Infiltration testing/ground investigation to assess the viability of using infiltration on site- there should be some ground testing for geology and then the worst case rates for that soil type should be used. o If the site is directing water to a single point of infiltration, then we would need to see infiltration testing for that location. However, if the water is being distributed evenly across the site as the rain lands on the ground, then we do not require infiltration testing as it is mimicking natural processes. o A site layout, location of features, outfall location, exceedance flows and conveyance. o A 10% allowance for urban creep must be included within the storage calculations. o Detailed engineering drawings of each component of the drainage scheme. Reason: To prevent the increased risk of flooding and to improve and protect water quality, in accordance with policy LP32 of the Peterborough Local Plan 2019 and Chapter 14 of the National Planning Policy Framework 2024. The condition is pre-commencement as it would be unreasonable to require applicants to undertake this work prior to consent being granted and the details need to be agreed before construction begins.
4. Prior to first occupation a maintenance plan detailing the maintenance arrangements shall be submitted and agreed in writing with the Local Planning Authority. The plan shall include who is responsible for different elements of the surface water drainage system and the maintenance activities/frequencies. Reason: To ensure appropriate maintenance arrangements are put in place to enable the surface water drainage system to function as intended to ensure mitigation against flood risk, in accordance with Policy LP32 of the Peterborough Local Plan 2019 and Chapter 14 of the National Planning Policy Framework 2024.
