The Surface Water Flood Extents are based on NRW s updated Flood Map for Surface Water (uFMfSW) For future/ climate change scenario, a broad scale assumption has been made for Stage 1 screening: Current 1 in 1000 (0.1%) annual chance flood outline becomes 1 in 100 (1%) with climate change. 1. NRW Flood Zone 2 - Assumed to approximate to 1 in 100 (1%) annual chance event with climate change. 4. The maximum 0.5% annual chance or greater extreme tide level plus sea level rise is 6.9m. A coarse 7m contour (not shown) has also been used to screen tide risk for coastal sites - see Stage 1 SFCA Report.
