Heavy rains in Mombasa cause flash floods, submerging roads in Bombolulu Estate 

Nothing like that. Over the years people have built houses where a STORM WATER DRAINAGE SYSTEM should be. This is not just in Mombasa but all urban centres and this will be a problem for years because as I can see even in your comment everything is politicised. To deal with this problem houses constructed in water pathways have to be DEMOLISHED and drainage systems built. I remember one Raila tried to do that in Nairobi and Mau forest see what he was called all sorts of names and ended being removed from that post. Kenya will never change
