Land Off St Lukes Road Llwyncelyn Porth RCT

1. 1.Insufficient information has been submitted to demonstrate that safe access can be achieved from the public highway, including adequate visibility and intervisibility between vehicles using the proposed access and the adjacent junction of Llwyncelyn Parc and St Luke's Road. In addition, the application fails to demonstrate that sufficient off-street parking can be provided in accordance with adopted standards. The resulting parking shortfall would be likely to increase on-street parking, to the detriment of highway safety and the free flow of traffic. Accordingly, the proposal would adversely affect highway safety and is contrary to Delivering Design and Placemaking: Access, Circulation & Parking Requirements SPG, Manual for Streets and Policy AW5 of the Rhondda Cynon Taf Local Development Plan.
2. 2.Insufficient information has been submitted to demonstrate that the proposed development would not result in unacceptable harm to biodiversity or the resilience of ecosystems, or that appropriate mitigation and enhancement measures can be secured. As such, the proposal fails to demonstrate how it would contribute to the sustainable management of natural resources, and is therefore contrary to Future Wales Policy 9, Chapter 6 of Planning Policy Wales, and Policies AW6 and AW8 of the Rhondda Cynon Taf Local Development Plan.
3. 3.The proposed development would result in the erection of a highly vulnerable form of development within Flood Zone 3 (Surface Water and Small Watercourses), as identified by Technical Advice Note (TAN) 15 and the Flood Map for Planning. In the absence of a satisfactory Flood Consequences Assessment and Drainage Statement demonstrating that the development can be safely accommodated without increasing flood risk, the Local Planning Authority cannot be satisfied that the proposal is acceptable. Consequently, the development is contrary to the requirements of Planning Policy Wales (Edition 12), Technical Advice Note 15: Development, Flooding and Coastal Erosion (TAN 15), and Policy AW10 of the Rhondda Cynon Taf Local Development Plan, and is therefore unacceptable in principle.
4. 4.The proposed development, by reason of its siting and layout, would prejudice access required for the ongoing maintenance, inspection and emergency repair of the adjacent watercourse and culvert. This would increase the risk of blockage and reduced hydraulic capacity, potentially resulting in increased flood risk both on-site and to neighbouring properties. Consequently, the proposal fails to demonstrate that it would be safe for its lifetime without increasing flood risk and is therefore contrary to the requirements of Planning Policy Wales (Edition 12), Technical Advice Note 15: Development, Flooding and Coastal Erosion (TAN 15), and Policy AW10 of the Rhondda Cynon Taf Local Development Plan, and is therefore unacceptable in principle.
