FLOOD DEFENCESGranting of planning permission for development subject to significant flood risk, will be linked to the improvement of flood defences (Adopted UDP Policy EN19) Planning permission will not be granted for any development that would prejudice the provision of flood storage basins or associated water channel improvements to be undertaken as part of the River Irwell Flood Control Scheme (UDP Policy EN20) The planning system should promote and enhance natural flood plains as they act as the natural regulator of river flow. (PPS25, para.C4) One of the best ways to mitigate the impact of flood risk is by restoring flood plains (Hallmarks of a Sustainable City p19) SEQUENTIAL APPROACHA sequential risk-based approach to determining the suitability of land for development in flood risk should be applied at all levels of the planning process. (PPS25, para.14) (Meeting the Sequential Flood Risk Test: Guidelines for the North West Region, p.iv) (RSS Policy EM5) Priority should be given in allocating or permitting sites for development, in descending order to the flood zones: Flood Zone 1: Low Probability (no constraint) Flood Zone 2: Medium Probability (suitable for most development) Flood Zone 3a: High Probability Flood Zone 3b: The Functional Floodplain (PPS25, para.D7) Regard will be had to the extent to which a development is located within or impacts upon a functional floodplain or flood zone (Adopted UDP Policy EN19) Where the Sequential Test is not possible, the Exception Test can be applied. Decision-makers should apply the test at the earliest stage possible in planning, to all LDD allocations for development and all planning applications other then for minor development. (PPS25, para.20 and Annex D) SUSTAINABLE URBAN DRAINAGE SYSTEMS (SUDS)Promote the use of sustainable drainage systems in the management of run-off (PPS1, para.22)(Adopted UDP Policy EN19) (RSS Policy EM5). Those proposing development are responsible for designs which reduce flood risk to the development and elsewhere, by incorporating SUDs and where necessary, flood resilience measures (PPS25, para.22) New development in High Flood Risk Zone 3, Medium Flood Risk Zone 2 and areas that suffer from sewer and surface water drainage flooding and new development of 1ha or more in Low Flood Risk Zone 1, should demonstrate that the disposal of surface water from the site will not exacerbate existing flooding (Flood Risk and Development Planning Guidance, Policy FRD11). Sustainable Drainage Systems should be used where practicable, particularly in areas prone to surface water flooding (Flood Risk and Development Planning Guidance, Policy FRD11). IMPLICATIONS OF CLIMATE CHANGEImplications of climate change for managing flood risk areas should be taken into account (RSS Policy DP1) Adaptation to climate change requires an integrated approach across different sectors including land use, water resources, transport, biodiversity and recreation. This integrated approach should be reflected in FRA. (PPS25, para.B13) Climate change will have a large impact on the region’s future demand for, and availability of, water and effective local and strategic management plans will be needed to address these important issues. (Spatial Implications of Climate Change, p.43) Climate change considerations should be integrated into all spatial planning concerns, including water supply, and not considered separately. (PPS: Planning and Climate Change, para.7) To address the challenges brought by climate change United Utilities intend to improve their understanding of surface water flood risk across the region and reducing water demand against a more uncertain water resource position should there be drier, hotter summers (Planning for the Future p3) FLOOD RISK ASSESSMENTSAny application for development likely to be at risk of flooding or materially increase the risk of flooding elsewhere, needs to be accompanied by a formal flood risk assessment (UDP Policy EN19)(PPS25, para.8 and Annex E) Regional FRAs will refer to Environment Agency Flood Maps and will utilize further information such as Strategic FRAs to allow flood risk to be taken into account in a broad regional context. (PPS25, para.D3) Local authorities should produce sub-regional or district level flood risk assessments, guided by the Regional Flood Risk Appraisal (RSS Policy EM5) The SFRA refines information on the probability of flooding, taking other sources of flooding and the impacts of climate change into account. The SFRA will provide the basis for applying the Sequential Test on the basis of the ‘Zones’ (see Sequential Test). Where the Exception Test is required, the scope of the SFRA will be widened. (PPS25, para.D4) A Flood Risk Assessment will be required to accompany planning applications for: any development proposals in High Flood Risk Zone 3; any development proposals in Medium Flood Risk Zone 2; or any operational development of 1ha or above in Low Flood Risk Zone 1 (Flood Risk and Development Planning Guidance, Policy FRD1).
