Decision 1. The appeal is allowed and planning permission is granted for sub-division of site and erection of a detached 2-storey single family dwelling at side/rear accessed via Old Park Grove involving associated parking, refuse storage at 1 Old Park Grove, Enfield EN2 6PW in accordance with the terms of the application, Ref 24/01578/FUL, subject to the conditions in the attached schedule. Main Issue 2.

1 Old Park Grove, ENFIELD, EN2 6PW — London Borough of Enfield — Appeal Decision The main issue is whether there is an adequate sustainable drainage strategy that demonstrates how the risk of flooding would be managed and utilises Sustainable Urban Drainage Systems. Reasons 3. The appellant provided a SuDS report with the application which the Council consider provided inaccurate information with regard to some of the calculations. I have reviewed the report and can see that the runoff attenuation was calculated having regard to the demolition of existing hard surfaced areas. In regard to the information provided within the report on runoff attenuation I am satisfied that while there is a minor difference, this is now less than originally indicated and as such is acceptable. 4. The Council consider that the greenfield run off rate should be calculated for the whole site area, based on the size of the proposed development. However, the appeal proposes the removal of an existing shed and outbuilding which would result in a change. The SuDS report has taken account of the removal of these hardscaped areas and therefore represents an accurate calculation for the greenfield run off rate. https://www.gov.uk/planning-inspectorate

1 Old Park Grove, ENFIELD, EN2 6PW — London Borough of Enfield — Appeal Decision Appeal Decision APP/Q5300/W/24/3351415 5. The SuDS system needs to store runoff from a 1 in 100-year event plus climate change and discharge as close to greenfield rates as possible. The amount of storage required has again been calculated on the basis of the removal of some hardscaped areas and proposes a stone rubble rain garden which has a storage volume in excess of the volume required. I am therefore satisfied that the amount of storage proposed would be adequate to store runoff from a 1 in 100-year event plus climate change. 6. I therefore conclude that the proposed drainage strategy would be adequate and the risk of flooding would be managed utilising Sustainable Urban Drainage Systems. I find no conflict with Policy SI 13 of the London Plan, Policies CP21 and CP28 of the Enfield Council Core Strategy Adoption November 2010, Policies DMD59, DMD60, DMD61 and DMD62 of the Enfield Development Management Document Adopted November 2014 and the Enfield Strategic Flood Risk Assessment 2008. Amongst other things, these seek to ensure that sustainable drainage measures are incorporated within new developments, direct developments to the lowest areas of flood risk and not increase flood risks elsewhere. Conditions 7.

1 Old Park Grove, ENFIELD, EN2 6PW — London Borough of Enfield — Appeal Decision I have considered the Council’s suggested conditions in the event I were to allow the appeal. Where necessary, and in the interests of clarity and precision, I have slightly altered them to more closely reflect the advice in the Framework and the Planning Practice Guidance. 8. Condition 1 is the standard condition which relates to the commencement of development and condition 2 specifies the approved plans for the avoidance of doubt. 9. Condition 3 is necessary in order to ensure a landscaping scheme and management plan is submitted. While I note that a landscaping site block plan has been provided with the appeal, the submitted plans are lacking some details and there is no information on management. 10. Condition 4 is required in order to ensure that a construction management plan is submitted to protect the living conditions of neighbouring occupiers. Condition 5 is required in order to ensure that details of the external materials and hard surfaced areas are submitted to and approved by the Council to ensure a satisfactory appearance. 11. Condition 6 is required in order to secure cycle parking to encourage the use of sustainable modes of transport for future occupiers.

1 Old Park Grove, ENFIELD, EN2 6PW — London Borough of Enfield — Appeal Decision Condition 7 is required in order to demonstrate reduced water consumption and condition 8 requires details of waste and refuse storage to ensure future occupiers have adequate provision. 12. Condition 9 seeks to ensure that no structures are erected to restrict the visibility of vulnerable users. Condition 10 is required in order to ensure that the machinery uses meets emission standards and condition 11 requires an energy statement to ensure emission targets are met. https://www.gov.uk/planning-inspectorate 2

The Council have proposed the removal of permitted development rights for buildings, extensions, windows and doors. However, the sites location which backs onto the railway and the windows and doors already proposed are either angled away from neighbouring properties or obscure glazed. I have therefore not found it exceptionally reasonable or necessary to remove these permitted development rights and I have therefore not imposed these conditions. Conclusion 14. For the reasons given above the appeal should be allowed.
