Review of plans, policies and

FLOODING

• 
  The planning system provides a framework for managing development and the use of land in ways which take into account the sustainable use of our natural resources, for example by designing in from the outset measures to tackle flood risk (UK Government Sustainable Development Strategy)
  
• 
  Ensure that flood risk is taken into account at all stages in the planning process to avoid inappropriate development in areas at risk of flooding, and to direct development away from areas at highest risk. (PPS25, para.5)(PPS1, para.20 and para.27 (iv))
  
• 
  Development will not be permitted where it would be subject to an unacceptable risk of flooding, will materially increase the risk of flooding elsewhere, or result in an unacceptable maintenance liability (UDP Policy EN18)
  
• 
  There should be an early consideration of flood risk in the formulation of RSSs, LDDs and proposals for development by RPBs, LPAs, the Environment Agency, other stakeholders and developers. This should identify opportunities for development of infrastructure that offers wide sustainability benefits (PPS25, para.33)
  
• 
  Those proposing development are responsible for identifying opportunities to reduce flood risk, enhance biodiversity and amenity, protect the historic environment and seek collective solutions to managing flood risk. (PPS25, para.22)
  
• 
  LPAs should notify the Environment Agency of the outcome of all planning applications for development in flood risk areas, including those for major development. (PPS25, para.29)
  
• 
  United Utilities plans to reduce by almost half the number of incidents of flooding of homes from overloaded sewers (Planning for the Future p3)
  
• 
  Local authorities should produce sub-regional or district level flood risk assessments, guided by the Regional Flood Risk Appraisal (RSS Policy EM5)
  
• 
  Development of new communities or the regeneration of existing ones, will, where possible, not be placed in unsustainable locations in terms of flood risk. (Sustainable Communities, para.3.12)
  
• 
  Use the best available science to provide a challenging vision for flood and coastal defence in the UK between 2030 and 2100 and so inform long-term policy. (Future Flooding, p.6)
  
• 
  Effective monitoring and review is essential to reducing and managing flood risk. (PPS25, para.35)
  
• 
  It is economically critical to ensure continued water quality and supply and to reduce the risk of flooding to households and businesses in Manchester, Salford and Liverpool (Atlantic Gateway p.26)
  
• 
  New residential development proposed in High Flood Risk Zone 3 should be designed and built such that floor levels for habitable rooms would be no more than 600mm below the flood level predicted for the 1:1,000 year flood event (Flood Risk and Development Planning Guidance, Policy FRD4).
  
• 
  New development in High Flood Risk Zone 3 should not result in a net loss of flood storage capacity (Flood Risk and Development Planning Guidance, Policy FRD5).
  
• 
  New development in High Flood Risk Zone 3 should not have an unacceptable impact on the effectiveness of known linear flood flow routes. Where possible new development should seek to enhance the effectiveness of flow routes and/or be designed to allow permeability to the through flow of water (Flood Risk and Development Planning Guidance, Policy FRD 6).
  
• 
  EA policy to:
  
  • 
    Take further action to prevent flood risk from the Manchester Ship Canal increasing in the future, initially working with the Manchester Ship Canal Company to better understand flood risk in this area (Sub area 1).
    
  • 
    To do more to understand flood risk in Manchester City Centre and to work in partnership with the City Councils on flood risk and development issues (Irwell Catchment Flood Management Plan Summary Report -
    
  • 
    Sub area 2)
    
  • 
    Take further action to reduce flood risk in Salford which might include constructing more flood defences or by making communities and properties more resilient to flood events through effective planning (Irwell Catchment Flood Management Plan Summary Report - Sub area 3)
    
  • 
    Take action to store water or manage run-off in Kearsley and Kersal to reduce flood risk further down stream in Salford and Manchester (Irwell Catchment Flood Management Plan Summary Report - Sub area 4)
    
  • 
    No large watercourse within Swinton and Eccles, actions to reduce flood risk relate to planning and development control (Irwell Catchment Flood Management Plan Summary Report - Sub-area 10)
    
  • 
    Flood risk us low in the Glaze sub-area and future changes will be driven by climate change. Reduce existing flood risk management actions, as current defences mostly protect rural land and isolated properties. In these locations the flood risk will be allowed to naturally increase over time (Mersey Estuary Catchment Flood Management Plan – Sub area 1)
