3. JE JACOBS October 2007 Cumbria County Council JE MVVDF STRATEGIC FLOOD R SK ASSESSMENT SFRA J ACOBS The SFRA has been developed building heavily upon existing knowledge with respect to flood risk within the district A rolling programme of detailed flood risk mapping within Cumbria is underway This in addition to observed flooding that may occur throughout a year will improve the current knowledge of flood risk within the district and may marginally alter predicted flood extents Furthermore Communities and Local Government CLG are working to provide further detailed advice with respect to the application of PPS25 and future amendmenis to the PPS25 Practice Guide are anticipated Given that this is the case a periodic review of the SFRA is imperative It is recommended that the SFRA is reviewed on a regular basis The following key questions should be addressed as part of the SFRA review process Question 1 Has any flooding been observed within the county since the previous review If so the following information should be captured as an addendum to the SFRA What was the mapped extent of the flooding On what date did the flooding occur What was the perceived cause of the flooding If possible what was the indicative statistical probability of the observed flooding event i e how often on average would an event of that magnitude be observed within the county If the flooding was caused by overtopping of the river
