supported by a Strategic Flood Risk Assessment and should take account ofadvice from the Environment Agency.5.14.7 In light of the above, the NPPF requires the application of a sequentialtest which steers new development to areas with the lowest probability offlooding. It recognises that it may not be possible for development to belocated in zones with a lower probability of flooding if it is to meet widersustainability objectives. In such cases, it allows an exception test to beapplied. For the exception test to be passed, it must be demonstrated that:• the development provides wider sustainability benefits to thecommunity that outweigh flood risk; and• the development will be safe for its lifetime taking account of thevulnerability of its users, without increasing flood risk elsewhere, and,where possible, will reduce flood risk overall.5.14.8 The NPPF further states that land that is required for current and futureflood management should be safeguarded from development. It also advises<strong>Local</strong> <strong>Plan</strong>s to use opportunities offered by new development to reduce thecauses and impacts of flooding.5.14.9 The Thames Estuary 2100 (TE2100) project aims to develop a longterm tidal flood risk management plan for London and the Thames Estuary.The proposed TE2100 Flood Risk Management <strong>Plan</strong> shows that there areunlikely to be major changes to the existing system of defences over the planperiod. However, it is likely that there will be changes in the longer term. Allthe options include a new flood defence to the north east of Gravesend andsome of the options include a new Thames flood barrier, either at LongReach, Dartford, or between Gravesend and Tilbury. This needs to be takeninto account in the Council's approach.5.14.10 A Strategic Flood Risk Assessment (SFRA) was carried out for KentThameside (Dartford and <strong>Gravesham</strong> Boroughs) in 2005 and updated in2009. This showed the different zones of flood risk in the Borough, particularlyfor potential development sites, to inform the application of the sequential andexceptions tests. It also made a series of recommendations including:177
