London Boroughs of Wandsworth, Merton, Sutton and Croydon Level 1 Strategic Flood Risk Assessment Appendix G – Surface Water Flooding Data London Boroughs of Wandsworth, Merton, Sutton and Croydon Level 1 Strategic Flood Risk Assessment Introduction This appendix presents further details of the surface water flooding mapping presented within Appendix A, Figures 9A – 9D. The source of the data presented as a point series in the maps has been provided for each of the four Boroughs. This will allow further consideration of the specific reason why each location has been highlighted to ensure that the actual risk is considered on a site by site basis where appropriate. Photographs of surface water flooding incidents obtained throughout the course of this study are also included for background information. Appendix G December 2008 i London Boroughs of Wandsworth, Merton, Sutton and Croydon Level 1 Strategic Flood Risk Assessment LB Wandsworth The information listed in Table G-1 below is the raw data provided by LB Wandsworth officers. Each location has been identified as a ‘problem area’ which is historically known to suffer from flooding during heavy rain. Other locations have been identified as at risk of sewer flooding, which have been mapped to allow consideration of potential flood flow paths from the overloaded sewer towards development site. Site specific FRAs should include consideration of the surface water problem areas highlighted on the maps. Table G-1 includes further information regarding the specific location of the problem area and the source of flooding issues, where available. This should be used to assess the risk to development and formulate suitable mitigation measures where appropriate.
