The cul de sac access is bad enough, but to design it to go below ground level was asking for trouble. This tunnel has flooded before and no doubt it will flood again. Since the last major flooding, I wonder how much grass area has been removed as this can act as a sponge?
The intensity and for the period of this extraordinary rain, it is not surprising that there was flooding, not only at the airport, but down in the town as well.
As for the congestion in the TMA, well this will be entirely solved during the spring of 2009
well if it doesn't rain heavily thereafter!
